Cannot Log In to Axon

If your Axon license expires, users cannot log in to Axon. Logged in users automatically log out of Axon at the time of license expiry.
Perform the following tasks if your Axon license expires:

Verify that the PostgreSQL Database Service is Running

To verify that the PostgreSQL database service is running, go to the <INSTALLATION_DIR>/axonhome/third-party-app/scripts directory in the Linux environment, and run the following command:
sh postgresql status
If the service is shut down, go to the <INSTALLATION_DIR>/bin directory, and run the following command to restart the Axon services:
sh startup.sh
Note: Use the same commands to verify that the database services is running for the PostgreSQL database deployed on a different node and external nodes, such Amazon RDS and Microsoft Azure Database for PostgreSQL.

Replace Your Axon License Key

To replace your Axon license key, perform the following steps:
  1. 1. Contact Informatica Global Customer Support to obtain a new license key.
  2. 2. In the Linux environment, replace the expired license key file with the new license key file in the following directory:
  3. <INSTALLATION_DIR>/axonhome/axon/
    Note: Make sure that the new license key file and expired license key file share the same name.
Note: When you clear the cache and restart the Axon services, the Axon web interface might be disrupted for some users that are logged into Axon. Informatica recommends that you update the cache after you save your changes in all the System Settings pages. Additionally, perform this action during a maintenance period when very few users are using Axon.
