The default Xmx setting for Datical is 2048m. If your machine has more than 4096m of RAM, you can increase the Xmx setting for RAM allocation as follows.
Desktop Client (Eclipse GUI)
For the desktop client/Eclipse GUI, you can increase the Xmx setting in your datical.ini file in your Datical DB installation directory:
In <datical-install>/datical.ini, change line -Xmx2048m to -Xmx4096m or higher.
Command Line (CLI)
There are two methods of changing the Xmx setting for the CLI. The first method using a command line option is usually preferred, because the command line option will persist no matter which version of Datical you are running. The second method of modifying Xmx in the bat or ini can be less desirable because you would need to edit the file again after each time you upgrade to a new Datical version. You can use whichever method better fits with your process or automation tools:
1. Command Line Option (recommended method)
When running a command, add the --vmargs -XmxNNNNm option to increase the RAM available. This method will persist after you upgrade to a new version of Datical. For example:
| Code Block |
|---|
hammer groovy deployPackager.groovy pipeline=<pipeline> scm=true --vmargs -Xmx4096m |
| Code Block |
|---|
hammer deploy <dbDef> --vmargs -Xmx4096m |
2. Editing .bat or .ini (alternate method)
Note that you would need to edit the file again after each time you upgrade to a new version of Datical. The instructions are different for Windows versus Linux:
Linux edit hammer-bin.ini
For Linux systems: In <datical-install>/repl/hammer-bin.ini, change line -Xmx2048m to -Xmx4096m or higher.
Windows edit hammer.bat
For Windows systems: In <datical-install>/repl/hammer.bat, change the set __cmd line to include RAM allocation in an -XmxNNNNm option. Example:
