Database Credentials

The command descriptions assume that database credentials are stored in the project (the default) or in environment variables.

If you have runtimeCredentials set and the credentials are not stored in environment variables, then you need to specify the database credentials on the command line.

We strongly recommend to use runtime credentials because it is more secure than stored credentials (due to the possibility of the stored password being decoded).

See Database Credential Management. 

Single-credential

Commands that work on a single database (dbdef) require the -un <username> and -pw <password> options to specify the database credentials.

Two-credential

Commands that work on two databases require credentials for the reference (desired state) and target (changed) databases

• Reference database:  Use -ru <username> and -rpw <password> options.
• Target database:  Use -tu <username> and -tpw <password> options.

add-to-property

Add a path to a property

USAGE

add-to-property <property> <path>

EXAMPLE

add-to-property drivers /home/user/newdrivers

NOTES

This command appends a new path to an existing property that expects path values.

addContexts

Add contexts to changesets. Adds context attributes to a set of changesets in the changelog. The attributes are selected using a label expression. This command is used by the Deployment Packager to indicate that a group of changesets is ready to be deployed to a new environment.

USAGE

addContexts --lookupChangesets=<label-expression> --context=<contexts> [--scriptChecksum=<checksum>] [--matchAll=true|false]

OPTIONS

• lookupChangesets - Label expression used to matchthe change sets (required)
• context - Comma-separated list of contexts (required)
• scriptChucksum - SQL script checksum value
• matchAll - SQL Script checksums must match for change set lookup. Default value is true. 

NOTES

The value of the scriptChecksum parameter can be used to further qualify change sets that match the label expression. This is used primarily in the Deployment Packager to confirm that the change set was generated by the expected version of a script.

The value of the matchAll parameter impacts the matching behavior of the scriptChecksum parameter.

• If matchAll is true, all change sets identified by the label expression must have a scriptChecksum attribute that matches the attribute passed on the command line.
• If matchAll is false, only one change set returned by the label expression needs to have a matching scriptChecksum attribute.

addLabels

Add labels to changesets. Adds label attributes to a set of changesets in the changelog that are selected using a label expression.

USAGE

addLabels --lookupChangesets=<label-expression> --context=<contexts> [--scriptChecksum=<checksum>] [--matchAll=true|false]

OPTIONS

• lookupChangesets - Label expression used to match the change sets (required)
• labels - Comma-separated list of labels (required)
• scriptChecksum - SQL script checksum value
• matchAll - SQL Script checksums must match for change set lookup. Default value is true

NOTES

The value of the scriptChecksum parameter can be used to further qualify change sets that match the label expression. This is used primarily in the Deployment Packager to confirm that the change set was generated by the expected version of a script.

The value of the matchAll parameter impacts the matching behavior of the scriptChecksum parameter.

• If matchAll is true, all change sets identified by the label expression must have a scriptChecksum attribute that matches the attribute passed on the command line.
• If matchAll is false, only one change set returned by the label expression needs to have a matching scriptChecksum attribute.

assignMetadata

Assign metadata information to a label. Used to associate more information with a label than could be expressed in the label itself. The metadata is stored in the project’s associated DMC database, so this command requires that an DMC database has been configured for the project.

USAGE

assignMetadata --metdataLabel=<label name> --metadataFile=<path to file>

OPTIONS

• metadataLabel - Name of the label
• metadataFile  - Path to a properties file containing the metadata key-value pairs

changelogSync

Mark all change sets as executed in the database. Marks all changesets as applied to the specified database.

USAGE

changelogSync <dbdef> <options>

EXAMPLE

changelogSync myAppDev --mergeLabels=merge --pipeline=Feature1

OPTIONS

• labels - Comma-separated list of labels
• mergeLabels - Label merge strategy, one of override (default), merge (AND), append (OR). Specifies how to combine labels set on the command line with labels set on the step. 
• pipeline - Specifies the pipeline associated with the changelogSync for reporting purposes.
  • If not set and the dbDef is a member of only one pipeline, then that pipeline is used.
  • If not set and the dbDef is a member of multiple pipelines, then an error is returned.

NOTES

USE CAUTION! Before running changelogSync, verify that the specified database is up to date!

Running changelogSync against a database that is not complete can lead to future deployment failures.

checkDrivers

Check that JDBC driver jars are installed or on the specified path. Scans the path(s) specified by the 'drivers' property for accessible JDBC drivers.

USAGE

checkDrivers

EXAMPLE OUTPUT

Found installed driver: com.ibm.db2.jcc.DB2Driver driver: (v3.63) jar: (v1.0.11.20181126111708)
Found installed driver: com.datical.jdbc.oracle.DaticalOracleDriver jar: (v0.0.60.20181126114644)
Found installed driver: com.microsoft.sqlserver.jdbc.SQLServerDriver driver: (v6.3) jar: (v1.0.11)
Found installed driver: oracle.jdbc.OracleDriver driver: (v18.3) jar: (v1.0.11)


NOTES

There are several ways to configure Datical DB to use the JDBC drivers that communicate with the databases being managed. The preferred method is to install the drivers into the OSGi environment using the installDrivers command. Drivers can also be found by creating a properties file in the project and then either

• manually editing the file
• using the command set property drivers <path-to-drivers>

For more information on setting the drivers property, see the help: help set property

checkRules

Compiles rules and reports any errors.

USAGE

checkRules [PreForecast|Forecast|PostForecast|SqlRules]

EXAMPLE

checkRules PreForecast

OPTIONS

• rulesFolder - specifies the folder to check, one of PreForecast, Forecast, PostForecast, SqlRules. These are the standard folders under the Rules folder for the project. If rulesFolder is not specified, then rules in all the standard folders are compiled.

NOTES

Run the command from a valid Datical DB project directory.

clearCheckSums

Delete the checksums used to detect altered change sets from the tracking tables.

USAGE

 clearCheckSums <dbdef>

EXAMPLE

clearCheckSums myAppDevDB

OPTIONS

NOTES

Use only under the direction of a Datical Support Engineer or if you are very experienced with Datical DB.

This command is helpful when you need to respond to a change to an existing object that is made outside of Datical DB. For example, someone uses a SQL script to change a database directly.  It allows you to update the change set that creates this object and clear the existing checksums to avoid validation errors. The checksums are recreated on the next deploy or changeLogSync command. 

create

NOTES

Run the command at the root of a project directory, <project>. 

For use case scenarios and examples, see Assembling Data for Datical Support. 

To include an external file, place it in the project directory, preferably in the root, <project>.

Do not use : or / characters in <searchstring>. If you search for a URL, do not include the prefix (http://, https://)

OUTPUT

OPTIONS

• <script-name> - path to a script name
• <script-options> - Options to pass to the script

NOTES

To access Datical DB commands through the script, access them through the DaticalDb object. The parameters for a command are (project, List<String> <[parameters]>). Use the word "project" as shown below.

Exceptions: add-to-property is accessed by addToProperty and deploy-autoRollback is accessed by deploy-AutoRollback.

Examples:

help(project, [])

help(project, ["groovy"])

show(project, ["dbprop", "myProject", "enableStorageOptions"])

help

Show help on Datical DB commands.

USAGE

help

help <command>|options

set help

show help

EXAMPLE

help diff

OPTIONS

• <command> - Name of the command you'd like to learn about.
• options - list of options used by the commands

NOTES

When run without a command option, lists all available commands and a brief description of each.

SEE ALSO

The set and show commands. 

history

Show the applied changeset history of a database. Shows all changesets that have been applied to the specified DbDef.

USAGE

history <dbdef>

EXAMPLE

history QAdb

OPTIONS

• <dbdef> - project dbdef name of the database to use.

insertSavedAuditData (deprecated)

Insert all audit entries temporarily saved in the project into the user-configured DMC DB.

USAGE

insertSavedAuditData --project=<path>
insertSavedAuditData

OPTIONS

•   project - Path to the project directory to use for inserting saved DMC DB data.

NOTES

If run without an option, the command runs in the current directory. The command fails if the directory is not a valid project directory.

Sometimes an operation (like deploy) encounters a condition that prevents information from being written to the DMC database. In that case, the information is saved to a temporary on-disk database. Use this command to move the on-disk data to the configured DMC database once connectivity to the DMC database has been restored.

installDrivers

Run the custom script installDrivers.groovy. Installs OSGi packaged JDBC drivers from the specified update site

USAGE

hammer installDrivers <driver_update_site>

EXAMPLE

hammer installDrivers http://update.datical.com/drivers/updates/

NOTES

Update sites can be either HTTP URLs (as shown above) or directories on a file system.

Examples of <driver_update_site>:

• Composite Archive (Windows and Linux):
     jar:file:/C:/Users/Pete/DaticalDBCompositeRepo-4.26.4467.zip
   jar:file:/home/Users/Pete/DaticalDBCompositeRepo-4.26.4467.zip

• Extracted Archive (Windows and Linux):

   file:/home/Pete/DaticalDBCompositeRepo-4.26.4467/

installLicense

Install a license file to allow continued use of Datical DB. Once a license is installed on a machine once, it does not typically need to be installed again.

USAGE

installLicense <path>

EXAMPLE

installLicense /home/datical/datdb.lic

OPTIONS

• <path> - Specifies where to find the file that contains the Datical DB product license.

NOTES

If you need to obtain or renew a license please email support@datical.com.

licenseCounter

Count the DbDefs in use for licensing validation.

USAGE

hammer licenseCounter <projects_dir> [ showDebug=true ]

EXAMPLE

Linux: hammer licenseCounter ~/datical
Windows: hammer.bat licenseCounter C:\Datical\Projects

OPTIONS

• <projects_dir> - Specifies the top directory to begin scanning project files.  It can be a relative or absolute path. All project files in the file hierarchy under this directory are scanned. 
• showDebug=true - Show additional detailed information as the command runs.  

NOTES

Output is sent to stdout. Redirect to a file to save it. 

modifyChangeSet

Modify changeset attributes

USAGE

modifyChangeSet --action=<action> --<modify-option>[=<value>, ...]... [--<search-option>=<value>, ...]...

EXAMPLE

hammer modifyChangeSet --action=ADD --modifyLabels=history --searchIgnore=true

hammer modifyChangeSet --action=REMOVE --modifyContext=QA4 --searchContexts=QA4

hammer modifyChangeSet --action=ADDALL --modifyContexts=DEV,PATCH01

hammer modifyChangeSet --action=REMOVEALL --modifyContexts=PATCH01

hammer modifyChangeSet --action=ADD --modifyIgnore --searchLabels=MyScriptName123.sql

hammer modifyChangeSet --action=ADD --modifyContexts=DEV,NEWCONTEXT --modifyLabels=MyTestSsisPackage --searchOrigFilePaths=ssis/MyTestSsisPackage

OPTIONS

Action

• action - Specifies the action to perform, one of ADD, REMOVE, ADDALL, REMOVEALL
  • All actions require at least one modify option. 
  • If you specify ADD or REMOVE, you must also specify a search option. 
  • If you specify ADDALL or REMOVEALL, do not specify a search option. If you do, the command fails with an error. 

Modify Option

At least one modify option is required. It specifies what change to make. It can be one of the following:

• modifyContexts - One or a comma-separated list of values for the context attribute.  
• modifyIgnore - Change the value of the ignore attribute. It does not take a value. The ADD action sets ignore=true. The REMOVE action sets ignore=false.
• modifyLabels - One or a comma-separated list of values for the label attribute.  

When a value is added to an attribute, it is added at the end of the existing list and the order of the list is preserved. If the value already exists, it is not added again. 

When a value is removed from an attribute, the order of the remaining values is preserved. 

When you specify more than one modify option, all modifications of the same type (context, ID, label) are put together and applied at one time. 

Search Option

The search options determine which changesets to modify. They select a list of changesets for the modify options to work on. 

Searches are not case-sensitive. 

• Multiple values in one statement are OR'ed together. 
• Multiple search option statements are ANDed together.

Search option statements take one or a comma-separated list of values. They are provided for changeset attributes as follows: 

• searchIds - id
• searchLabels - label
• searchContexts - context
• searchIgnore - ignore - true | false - Searches for false also return changesets where the ignore attribute is not set. true | false
• searchOrigFilePaths - origFilePath
• searchOrigFileNames - origFileName
• searchVersion - version, an integer. 

OUTPUT

The command reports the number of changesets that met the search criteria. If no changesets meet the criteria, the command succeeds and reports that no changesets met the search criteria. 

ERRORS

The command fails and reports an error when:

• No action is specified or an invalid value is specified.
• An action is valid but no modify options are specified.
• ADDALL or REMOVEALL is specified as an action and a search option is specified. 
• ADD or REMOVE is specified as an action and a search option is not specified. 
• An invalid value is specified for searchIgnore. It must be true or false.  

NOTES

The modifyChangeSet command is intended to make it easier to work with labels and contexts.

• Searching - Make it easier to find a changeset: Search by criteria other than a label name, particularly criteria that can be unique (origFilePath, origFileName, ID).
• Labels - Manage labels for a release, especially for later steps in a pipeline.
• Contexts - Use context settings as a gating mechanism for deploying to a specified environment (context)

Context expressions and label expressions are not currently supported. Use comma-separated lists for multiple values. 

Starting with version 4.32, Use this command rather than the following commnds, which are deprecated and may be removed in a future release:

• addLabels
• removeLabels
• addContexts
• removeContexts

releaseLocks

Reset the lock Datical creates in an environment to prevent concurrent Datical operations.

USAGE

        hammer releaseLocks <dbDef>

EXAMPLE

        hammer releaseLocks PROD_DB 

NOTES

        Typically this lock is cleared at the end of a deployment but a deployment that ends prematurely may leave this lock in place. Subsequent deployments to such an environment will fail until the lock is released.

removeContexts

Remove contexts from changesets. 

USAGE

removeContexts --lookupChangeset=<label-expression> --context=<contexts> [--scriptChecksum=][--matchAll=true|false]

OPTIONS

• lookupChangesets - Label expression used to matchthe change sets (required)
• context - Comma-separated list of contexts (required)
• scriptChucksum - SQL script checksum value
• matchAll - SQL Script checksums must match for change set lookup. Default value is true. 

NOTES

The value of the scriptChecksum parameter can be used to further qualify change sets that match the label expression. This is used primarily in the Deployment Packager to confirm that the change set was generated by the expected version of a script.

The value of the matchAll parameter impacts the matching behavior of the scriptChecksum parameter.

• If matchAll is true, all change sets identified by the label expression must have a scriptChecksum attribute that matches the attribute passed on the command line.
• If matchAll is false, only one change set returned by the label expression needs to have a matching scriptChecksum attribute.

removeLabels

Remove labels from changesets. 

USAGE

removeLabels --lookupChangeset=<label-expression> --context=<contexts> [--scriptChecksum=][--matchAll=true|false]

OPTIONS

• lookupChangesets - Label expression used to matchthe change sets (required)
• context - Comma-separated list of contexts (required)
• scriptChucksum - SQL script checksum value
• matchAll - SQL Script checksums must match for change set lookup. Default value is true. 

NOTES

The value of the scriptChecksum parameter can be used to further qualify change sets that match the label expression. This is used primarily in the Deployment Packager to confirm that the change set was generated by the expected version of a script.

The value of the matchAll parameter impacts the matching behavior of the scriptChecksum parameter.

• If matchAll is true, all change sets identified by the label expression must have a scriptChecksum attribute that matches the attribute passed on the command line.
• If matchAll is false, only one change set returned by the label expression needs to have a matching scriptChecksum attribute.

rollback

Roll back the target database to a specified revision, date or by number of steps.

USAGE

rollback <dbdef> lastlabel
rollback <dbdef> changeid:<changesetId>
rollback <dbdef> count:<num>
rollback <dbdef> date:<date>
rollback <dbdef> tag:<tag_name>
rollback <dbdef> lastDeploy

EXAMPLE

rollback <dbdef> lastDeploy --pipeline=FeatureA

OPTIONS

• lastlabel - Remove all changes associated with the last label deployed. Certain preconditions must be met for this mode to succeed.
• changeid:<changesetID> - Roll back to the <changesetId> change set in the change log.
• count:<num> - Roll back the last <num> change sets.
• date:<date> - Roll back all change sets applied after <date>.
• tag:<tag_name> - Roll back to <tag_name>. The tag <tag_name> must have been specified for a previous changeset.
• lastDeploy - Remove all changes associated with the last deploy operation. 
• pipeline - Specifies the pipeline associated with the changelogSync for reporting purposes.
  • If not set and the dbDef is a member of only one pipeline, then that pipeline is used.
  • If not set and the dbDef is a member of multiple pipelines, then an error is returned.

OPTION VALUES

• <dbdef> - Name of a DbDef in the current project.
• <changesetId> - The author and id of a change set. Format: "id=createTable1,author=Datical User"
• <num> - Number of change sets to revert.
• <date> - Date boundary used to determine which change sets will be reverted. Format: yyyy-MM-dd
• <tag_name> - Datical tag name to which you wish to rollback. Requires that you tag the database in a previous change set.
  
  

runRules

Runs rules from the SQLRules folder on the specified SQL file or folder of SQL files.

USAGE

runRules [<SQL-file> | <SQL-file-folder>]

NOTES

Deployment Packager runs the runRules command as part of packaging.  You can use it to check SQL files before checking them in for packaging. 

The command must be run from a project directory: datical/<project>.

In the workspace (datical), the SQLRules directory is under the Rules directory in a project: datical/<project-name>/Rules/SQLRules.

schemaStats

Display summary schema info. Shows summary info about the database model represented by the changelog.

USAGE

schemaStats

set

Set properties for the project and database. 

The set command provides help for the subcommands.

USAGE

set <property> <values>

set help

PROPERTIES

• alternateSchema - Set the alternate schema for the project.

USAGE: set alternateSchema <schema name>

• autoGenSQL – control whether or not SQL scripts are automatically generated during Forecast, Deploy, and Rollback operations.

USAGE: set autoGenSQL true|false

• dbprop - Set a database property in a project.

USAGE: set dbprop [dbdef] [propertyName] [propertyValue]

• dbdef - the name of a database definition in the current project.
• propertyName - a property name. The only property currently supported is enableStorageOptions. This property controls whether or not storage options are collected for a specific database definition during the snapshot command. Storage Option information includes storage configuration, tablespace/filegroup assignments, large object storage parameters and partitioning information for tables and indexes. This defaults to false.
• propertyValue - a property value (must be valid for the type of the property).

EXAMPLE: set dbProp QDdb enableStorageOptions true

• deployMode – controls how much work is done during Deploy operations. 

USAGE: set deployMode quick|full

• full - performs rules validation and runs a forecast before deploying the changes, subject to limitForecast.
• quick - deploys the changes (no rules valildation or forecast)
• deployThreshold – controls what happens when a full deploy detects errors or warnings in rules or in forecast.

USAGE: set deployThreshold stopOnError|stopOnWarn|deployAlways>

• stopOnError - Deployment is not performed when errors are present in Pre-Deployment validation
• stopOnWarn - Deployment is not performed when errors and/or Warnings are present in Pre-Deployment validation
• deployAlways - Deploy proceeds regardless of validation results. NOT RECOMMENDED
• enableRowCount - set method for counting rows in tables. 

• Changed in v5.7 from true | false with default of true. New default is disabled. Older projects are interpreted correctly and mapped to the new values. 

  USAGE: set enableRowCount exact | approximate | disabled

  • exact - Uses a table scan to count the number of rows in each table. 
  • approximate - Uses database statistics to approximate the number of rows. 
  • disable - Does not count table rows. 
• enableSqlParser - set use of SQL Parser to allow forecasting of DIRECT and DATA_DML scripts

USAGE: set enableSqlParser true | false

• true -  use SQL Parser to parse DIRECT and DATA_DML scripts into the Daticals object model for subsequent validation with rules and forecast.
• false - disable SQL Parser.  
• externalStoredLogic - Set whether stored logic definitions (stored procedures, etc.) are stored in external files or within the project changelog.

USAGE: set externalStoredLogic <true|false>

• forecastDML - For Oracle only, controls whether Datical DB attempts to forecast DML (Data Manipulation Language). 

USAGE: set forecastDML true | false 

• true - forecasts predict whether a DML change will be successful
• false - forecasts warn that any DML change encountered will not be forecast
• help <property> - show more help about a property. 
• invalidsCheck – controls how to check the validity of stored logic after deployment

USAGE: set invalidsCheck disabled|limited|local|global

• disabled - do not perform the check
• limited - only check objects targeted by a deployment and their dependencies
• local - check the target schema only
• global - check all schema in the database
• invalidsAction – controls how to check the validity of stored logic after deployment
  

  USAGE: set invalidsAction warn|fail

  • warn - print a warning message if invalidsCheck does not pass. 
  • fail - print an error message if invalidsCheck does not pass for new stored logic objects. Print a warning if the check does not pass for objects that already exist in the database.  If set to fail and a package operation encounters the error during deployment to REF, the package operations fails and the database is restored to its state before the packaging operation was started. 
• limitForecast - controls how Datical DB behaves during forecast operations. Forecast operations run faster if set to true, but some rules are not checked. 

USAGE: set limitForecast true|false

• true - limit object profiling to those directly affected by the forecast 
• false - profile all objects in the target database
• property - Sets the specified property to a given value. The only property currently supported is drivers. This points to the directory where you've stored your JDBC drivers.

USAGE: set property [propertyName] [propertyValue]

EXAMPLE: set property drivers /path/to/driver/dir

• requireOptions – controls whether or not labels or contexts are required for Forecast and Deploy

USAGE: set requireOptions true|false

• runtimeCredentials - controls whether database credentials are stored or prompted at run time. Default: false. If set to true, all stored credentials are removed and you are prompted for database credentials during forecasting and deployment. If set to false, database credentials are encoded and stored in the project.   We strongly recommend to use runtime credentials because it is more secure than stored credentials (due to the possibility of the stored password being decoded).

USAGE set runtimeCredentials true|false 

• true - all stored credentials (if any) are removed. You are prompted for database credentials during forecasting and deployment.
• false - (default) database credentials are stored in the project.

• scriptExecutionTimeout - sets a limit on how long Datical DB will wait for a script to run.  We recommend setting a value for this for all of your REF dbDefs, but only your REF dbDefs.

USAGE: set scriptExecutionTimeout <dbdefName> <seconds> 

• dbdefName - name of the dbdef where the limit is applied
• seconds - number of seconds. If set to 0, there is no timeout limit. The default value is 0. 
  
  
• storageOptionsScope - Specifies what storage information to use in snapshot and diff operations for all steps/dbdefs in the project. For <arg>, specify one of all, lob, tablespace, tablespaceAndLob.  The default is all. This setting works only for steps/dbdefs that have enableStorageSettings set to true. 

USAGE: set storageOptionsScope <arg>

• • <arg> - one of  all, lob, tablespace, or tablespaceAndLob
