This can be caused by the following.
1. The Database is down. Check with the DBA to confirm the SQL or Oracle database is up and running.
2. Database password was changed or changes once every 6 months. Change password configurations to never expire or set a schedule so teams using the database are aware and can prepare for the change.
3. Max-pool-size on the database limit is reached. The values are found in ca-standalone-full-ha.xml (/opt/CA/wildfly-idm/standalone/configuration). Increase as needed. I set to 1000.
