After installing Data Catalog, there may be other components you need to set up, depending on your environment. Use the following topics as needed, to finish setting up your environment.

Configure system environment variables

 

Although not common, there may be instances where you need to change the default settings for Data Catalog system environment variables. These configuration modifications allow you to override default system behavior to align with your specific needs.

 

CautionModifying these settings can have system-wide implications, and incorrect changes may negatively impact the functionality of the other platforms. It is a best practice to collaborate with your Pentaho Data Catalog partner to ensure that any modifications align with your intended objectives.

Procedure

  1. In a terminal window, navigate to the pdc-docker-deployment directory and open the hidden environment variable configuration file (.env). This file is located in the /opt directory by default.

  2. Verify the system environment variables set in the /opt/pentaho/pdc-docker-deployment/vendor/.env.default file:

    • For example, the number of worker instances that Data Catalog uses to run processes is set to 5: 
      PDC_WS_DEFAULT_OPS_JOBPOOLMINSIZE=5
PDC_WS_DEFAULT_OPS_JOBPOOLMAXSIZE=5
      NoteMake sure that PDC_WS_DEFAULT_OPS_JOBPOOLMINSIZE and PDC_WS_DEFAULT_OPS_JOBPOOLMAXSIZE have the same value for consistent worker instance management.

  3. To override an environment variable set in the vendor/.env.default file, you can create a new .env file in the opt/pentaho/pdc-docker-deployment/conf/ folder:

    vi opt/pentaho/pdc-docker-deployment/conf/.env

  4. After adding all required system variables, save your changes and restart the Data Catalog system services.

    ./pdc.sh stop
./pdc.sh up
