You need to update PowerExchange libraries and configuration files to ensure compatibility with the CDI-PC 2025.04.M update.
Based on the PowerExchange version that you want to update, review and update key configuration files, adjust environment variables, and verify that the PowerExchange Listener and Logger Services in the Administrator tool match the updated configurations.
Before you update
If you use PowerExchange, back up the dbmover.cfg file before you update the domain. After you complete the domain update, copy the dbmover.cfg file to the new <CDI-PC HOME>\usr\config\pwx\ directory. If you have configured an overrides.cfg file, make sure that you copy the overrides.cfg file to the new directory.
Whether you run SSL-enabled environments, use PowerExchange Listener or Logger service, or maintain an on-premises PowerExchange installation, use the following instructions to update CDI-PC from the October 2024 release to April 2025 release and effectively manage different PowerExchange update scenarios.
When neither SSL is used nor a PowerExchange on-premises installation exists
- Update the CDI-PC domain directly to the CDI-PC April 2025 release.
- No additional configuration or actions are required.
When SSL is enabled in the PowerExchange network
Before updating to the CDI-PC April 2025 release, complete the following tasks:
- In the DBMOVER configuration file, update existing SSL_CONTEXT_METHOD statements to select TLSV1_2.
- Update SSL certificates. Note that OpenSSL 3.3.1 rejects certificates with an RSA key smaller than 2048 bits or signed with SHA1.
- If you're running a PowerExchange 10.4.x Listener, upgrade it to version 10.5.x or later before updating to the CDI-PC April 2025 release.
When PowerExchange Listener or PowerExchange Logger services are used with an on-premises PowerExchange installation
Before updating to the CDI-PC April 2025 release, complete the following upgrade tasks for PowerExchange 10.5.8:
- Install PowerExchange 10.5.8 alongside the current PowerExchange installation.
Note: Do not uninstall your existing PowerExchange installation.
- Complete all the standard upgrade procedures for PowerExchange 10.5.8.
- Create a copy of the existing PowerExchange configuration files, such as dbmover.cfg and pwxccl.cfg, and update the copied files as required to ensure compatibility with PowerExchange 10.5.8. For more information, see DBMOVER Configuration File.
- Align with the configuration values and configuration file locations of the PowerExchange 10.5.8 installation. For more information, see PowerExchange Listener Overview.
Before you apply the CDI-PC April 2025 release update, complete the following tasks:
- Stop all running workflows.
- Shut down the entire PowerExchange environment.
- Update environment variables, such as, PATH, LD_LIBRARY_PATH, and PWX_HOME, to point to the PowerExchange 10.5.8 installation directory.
- If any PowerExchange configuration file locations have changed, update the PowerExchange Listener and Logger Services settings in the Administrator tool as necessary.
- Update CDI-PC to April 2025 release.
- After completing the update, resume all workflows.
If you use PowerExchange on-premises installation instead of the CDI-PC PowerExchange client
- If you do not require the PowerExchange on-premises installation, switch to the CDI-PC PowerExchange client before you update to CDI-PC April 2025 release.
- If you use the PowerExchange on-premises installation because of a workaround recommended by Informatica Global Customer Support and the issue is resolved in the CDI-PC April 2025 release, switch to the CDI-PC PowerExchange client during the upgrade.
- If you want to continue using the existing PowerExchange on-premises installation version after you update to CDI-PC April 2025 release, make sure the following conditions are met:
▪ If you use SSL or the PowerExchange Listener or Logger service, you must upgrade to PowerExchange version 10.5.8.
▪ If you're not using SSL or the PowerExchange Listener or Logger service, you can continue using a earlier PowerExchange version.
Post-update task for PowerExchange for PostgreSQL
If you use PowerExchange for PostgreSQL and upgrade the CDI-PC domain, the PostgreSQL mappings might fail unless you register the PostgreSQL plugin again and verify the override schema changes.
1 Copy the following file from the CDI-PC node to your workspace:
<INFA_HOME>/server/bin/Plugin/postgres_Plugin.xml
2Log in to Informatica Administrator (the Administrator tool) and go to Manage > Services and Nodes.
3Select the CDI-PC Repository Service and change the operating mode to Exclusive.
The repository service restarts in exclusive mode.
4In the Contents panel of the repository service, click the Plug-ins view.
5In the Actions menu of the Domain tab, select Register Plug-in.
6Select the file you copied in 1, and select Update existing plug-in registration.
7Enter the user name, password, and the security domain.
8Click OK.
The CDI-PC Repository Service registers the plug-in with the repository. The results of the registration operation appear in the activity log.
9On the Properties tab of the repository service, change the operating mode to Normal.
