[java] [ main] [ ] [ ] ( internal.util.MoveLog) INFO - Processed 1100 of 2325 (47.31%): 1100 committed, 0 skipped, 17 seconds remaining



Steps to Reproduce

  1. Upgrade PRPC 6.3 SP1 to Pega 7.2
  2. Run upgrade.sh on an Oracle database from a UNIX environment.


Root Cause



A defect or configuration issue in the operating environment.

Oracle JDBC driver gathers entropy during upgrade or install while using UNIX. Oracle JDBC drivers use /dev/random by default. When running in an environment where there is not a lot of noise, the entropy pool eventually gets empty and the connection is reset. In some versions of the driver there are long hangs and then the connection restores. In other versions, SQLRecoverableException is observed and the connection is closed.

Resolution



Use Oracle's suggested local-change to set the system property, 
-
Djava.security.egd=file:///dev/urandom:

Modify the setupDatabase.xml file to set the system property and resume the upgrade.
