Description (partial)

Issue found on 15 K test bed after VM was Powered OFF unexpectedly. After VMs are powered ON, CUP couldn't start Sync Agent Service. CUP Version: 241.

Error in Sync Agent log:
2014-10-08 14:15:30,199 ERROR [main] dbl.Connector - connect() SQLException
java.sql.SQLException: No suitable driver found for jdbc:informix-sqli://;IFX_LOCK_MODE_WAIT=10;DB_LOCALE=en_US.utf8;CLIENT_LOCALE=en_US.utf8;;IFX_SOC_TIMEOUT=300000;INFORMIXCONTIME=7;user=dbuser;password=22bb31d55723
at java.sql.DriverManager.getConnection(
at java.sql.DriverManager.getConnection(

After analyzes it is found that the root cause of the error is that CUCM was not connectable when CUP db was starting up. It could be due to: 

1)DNS issue 2) network issue 3) CUCM was down or the RPC service on CUCM was stopped

Work around for this issue is to restart A Cisco DB service.

CUP VM was Powered OFF unexpectedly.
