Updating to Celonis Process Mining 4.7.3

Please be aware that before updating to Celonis Process Mining 4.7.3, it is required to install and run version 4.7.2. 

For detailed information and further required steps, please refer to the Celonis 4.7.3 - Update Guide 1.14. All updated guides can be found here.

Not adhering to these instructions can lead to loss of configuration! These steps are not necessary in case of a fresh installation. Only application updates are affected.

Important Changes

1. Deprecation note: Optimized load

With Celonis Process Mining 4.7.3, we are deprecating parts of the “optimized load” functionality (Data Model → Loading → Load column).

Remaining functionality:

The user can manually select which columns of a certain table are included/excluded from a data model load.

Deprecated functionality:

  • The application no longer tracks the access count and last access dates for columns
  • The “Load only used columns” functionality is no longer available. This functionality was used to automatically include columns that were not available but accessed by a user into the next load

2. MS SQL Configuration Store - JDBC Driver


In case the application is configured to use the Celonis Configuration Store based on MS SQL in config-custom.properties, a manual  update has to be applied:

Validating the usage of MS SQL

  • Navigate to <installDir>/config-custom.properties
  • Check if this exact property exists within your config-custom.properties file. In case the property is commented (#) the manual update does not have to be applied:
Code Block
themeEclipse
database.dialect=org.hibernate.dialect.SQLServer2008Dialect

For detailed information and further required steps, please refer to the Celonis 4.7.2 - Update Guide 1.13. Not following this instruction will lead to all Amazon Athena connections failing

How to update the property

  1. Navigate to <installDir>/config-custom.properties
  2. Replace the old value org.hibernate.dialect.SQLServer2008Dialect of the property database.dialect with the following value:
Code Block
themeEclipse
de.celonis.pm.utils.engine.CPMSQLServer2012Dialect


3. Microsoft JDBC Driver for SQL Server Authentication Library for Windows


We also removed the mssql-jdbc_auth-<version>.x<64/86>.dll (Microsoft JDBC Driver for SQL Server Authentication Library for Windows) from the embedded dependencies. In case the application is running on Windows and the SQL Server Authentication (indicated by integratedSecurity=true in the JDBC string) is used to connect to the Celonis Configuration Store or the Analytics Database, the library has to be deployed manually.

Please refer to the Celonis Update Guide 1.14 for more information. Not applying this configuration can lead to MS SQL connections failing.

How to deploy the driver

  1. Stop the application
  2. Download the respective driver version based on your SQL Server version and compatibility from here. Please follow the Microsoft recommendations in case of any questions: here.
  3. Place the library in <installDir>\jre\bin
  4. Start the application


4. Updated log file structure & log rotation


With version 4.7.3, we revamped the full log file structure on the application server. In addition to that, we enabled log rotation by default for the main Celonis Frontend and Compute Compute service logs.

Please refer to the Celonis Update Guide 1.14 for more information.

WindowsLinux

Celonis CPM4 Frontend

    • <installation_directory>/logs/cpm_svc.err.log
      <installation_directory>/logs/cpm_svc.out.log
      <installation_directory>/logs/cpm_svc.wrapper.log
      Windows Service Wrapper logs (when starting Celonis CPM4 Frontend service)
    • <installDir>/logs/cpm-stdout.log
      Celonis CPM4 Frontend startup messages (before full application server start)
    • <installation_directory>/logs/cpm.log
      Celonis CPM4 Frontend general service log file for current date (today’s logs)
    • <installation_directory>/logs/cpm.<date>.log.gz
      Celonis CPM4 Frontend archive service log files, rotated daily by default

Celonis CPM4 Compute

    • <installation_directory>/compute/logs/cpm_svc.err.log
      <installation_directory>/compute/logs/cpm_svc.out.log
      <installation_directory>/compute/logs/cpm_svc.wrapper.log
      Windows Service Wrapper logs (when starting Celonis CPM4 compute service)
    • <installDir>/compute/logs/compute-stdout.log
      Celonis CPM4 compute startup messages (before full compute server loading)
    • <installation_directory>/compute/logs/compute.log
      Celonis CPM4 compute general service log file for current date (today’s logs)
    • <installation_directory>/compute/logs/compute.<date>.log.gz
      Celonis CPM4 compute archive service log files, rotated daily by default

    • <installDir>/logs/cpm-stdout.log
      Celonis CPM4Frontend startup messages (before full application server loading)
    • <installDir>/logs/cpm.log
      Celonis CPM4 Frontend general service log file for current date (today’s logs)
    • <installation_directory>/logs/cpm.<date>.log.gz
      Celonis CPM4 Frontend archive service log files rotated, daily by default

Celonis CPM4 Compute

    • <installDir>/compute/logs/compute-stdout.log
      Celonis CPM4compute startup messages (before full compute server loading)
    • <installation_directory>/compute/logs/compute.log
      Celonis CPM4 compute general service log file for current date (today’s logs)
    • <installation_directory>/compute/logs/compute.<date>.log.gz
      Celonis CPM4 compute archive service log files rotated, daily by default


5. Custom logging configuration


The custom logging configuration was updated with version 4.7.3. It was previously configured in <installDir>config-custom.properties via the property logging.config=. This property is no longer supported. 

  • If custom logging was configured previously, please migrate the configuration to the approach (see the next slide).
  • If scheduled OS logrotate was configured, please deactivate it and use the default CPM4 log rotation. Alternatively, you can apply a custom logging configuration as highlighted on the next slide.

Please refer to the Celonis Update Guide 1.14 for more information. Not applying this update will lead to the application not picking up the previous custom logging configuration.

How to apply a custom logging configuration

  • Refer a custom logging config file using the JVM property -Dlogging.config in <installDir>/cpm.user.vmoptions
  • Refer a custom logging configuration in the file application.properties#logging.config residing in the same directory as the application jar.
Info
titleNote
The logging library was changed from log4j2 to logback. Therefore, an update to the  logging.xml configuration format could be required. For more information, please refer to: https://logback.qos.ch/manual/configuration.html





Improved Conformance Checker

1. Custom dimension

The Conformance Checker component can now be configured to use a custom dimension in two places (requires being in edit mode):

  • During the setup when selecting “mine process model”
  • In the component settings


2. Improved violation list

The violation list is now paginated for better usability and performance.

Additionally, violations can now be added to the allowlist directly, without opening the detail screen.

2.




Color mapping based on Null

Previously, the color mapping of analysis components was limited to numeric values. Therefore, we added the option to map null values to a specific background or font color.




Improved "Scheduled loads" overview

We added more information to the “Scheduled loads” overview (System Settings → Data loads → Scheduled loads):

  • Data model ID
  • Load ID
  • Load schedule/partial load schedule
  • Schedule configuration


Info
titleNote

If a load schedule as well as a partial load schedule are configured for the same data model, there will be two separate entries on the page.




Improved system monitoring

1. Storage metrics

The application now logs the available and used storage of config.properties#filesystem.writableroot= (once per hour).


2. Data Model Load Pool metrics:

The application now logs information about the Data Model Load Pool configuration (config-custom.properties#model.max.parallel) and workload (once per hour).

Examples:

Code Block
themeEclipse
titleStorage metrics
<yyyy-MM-dd'T'HH:mm:ss.SSSXXX> INFO ResourceMonitor - [STORAGE (writable root)] available 64 GB, used 32 GB (50.00%)
Code Block
themeEclipse
titleData Model Load Pool metrics
<yyyy-MM-dd'T'HH:mm:ss.SSSXXX> INFO ResourceMonitor - [Data Model Load Pool] current pool size = 3, maximum pool size = 6, active tasks = 0, completed tasks = 3, queued tasks =
