We encountered one issue in the last production change and getting an exception on the UI while submitting enrollments to downstream system.

Please find the steps which we performed.

  1. Deleted the Database instance as this is duplicate and having database connection string, username / Password hard coded in this instance and we have already PEGA_RULES with JNDI connection.
  2. After that we bounced all Pega servers.
  3. As part of testing killed one database instance to check the application availability and database server automatically restarting or not? (we have a RAC node solution in the Database)
  4. Oracle server restarted successfully and traffic routed to the second instance successfully.
  5. We were able to login into application, and able to create enrollments & at final submission process to downstream system getting an exception on the UI <<Implementation class name>> Java.lang.NoClasssDefFoundError:Com/Pega/apache/log4J/spi/ThrowableInformation


  1. We need to bounce Pega Serves bounce or not ? after the oracle instance restarted.


Observed this error in the log files while testing. << Security Access Error: Fail: No credentials supplied >>


Veera Illuri.
