Advanced configuration and integration
The application configuration is stored in the following file:
<PM_HOME>/etc/processmining.conf
When you introduce changes to the processmining.conf file, make sure you do it correctly. For more information, see Configuration file editing guidelines.
Password encryption
You must encrypt the passwords for DB connection or SMTP connection before storing the information in the configuration file.
You can use the crypto-utils command-line tool to encrypt and decrypt passwords, located in <PM_HOME>/crypto-utils:
./crypt-utils.bat myPassword
./crypt-utils.sh myPassword
If the original password includes the $ character, then you must enclose the password in single quotation marks as denoted in the following sample:
./crypt-utils.sh 'test$1'
Horizontal Scaling of long running procedures
Some of the methods, for example Running case detection, Computing replay, and Computing case analysis, started by Process Mining are time-intensive and are currently performed as a single-thread process.
The following table describes the parameters that you can use to improve this process.
| Parameter | Description | Default value |
|---|---|---|
engine.defaults.runningCaseDetectionParallelism |
Indicates the parameter to set parallelism for the running case detection algorithm. | (machine core number)-4 |
engine.defaults.processReplayParallelism |
Indicates the parameter that determines the parallelism of the replayLog. You might not get a better performance when the value is set to more than 4 or 5. Hence for better performance, set the value to 4. This is applicable only for legacy multilevel processes. There is no impact on flat processes. |
2 |
engine.defaults.caseAnalysisParallelism |
Indicates the parameter to parallelize the calculation algorithm of the case analysis | Max(2, (machine core number) -1) |
engine.defaults.defaultParallelism |
Indicates the parameter to set the value of parallelism for most of the long running executions. For example: log variants extraction for analytics, custom metric filters, and diff analysis. | 4 *If the workstation has more than 16 cores, set the value to 6. |
| engine.defaults.planner.maxWidthPerQuery | Indicates the parameter to set the value of parallelism for analytics queries executions. If you encounter performance problems when retrieving analytics widgets, increase this parameter gradually until reaching a maximum of half the maximum number of cores of the workstation. | 4 |
