Defect/Enhancement Number
Cause
Error indicates that the machine hosting Savvion Business Manager (SBM) is not able to connect with the database.
 
Resolution
After a few minutes, try restarting the Savvion servers once again. The error could have been thrown due to a temporary network failure.
If the exception occurs continuously, it could be due to different reasons. The following checklist verified in the order presented can help understand the specific reason for the error.

1. Can the machine hosting Savvion (<savvion_host>) reach the machine where Oracle is installed (<oracle_host>)? (From savvion_host, ping oracle_host> ) If NO, the two machines are not connected to each other on the network.
Enlist help of Network Administrator to verify if there was an issue with the network.

2. Does a "telnet <oracle_host> <oracleListenerPort>" work? If NO, this could indicate that the Oracle instance / listener has not been started.
The person managing the database in the Organization should be able to help.
3. Try using a different SQL client such as SQL Developer / Squirrel SQL Client to check if database is accessible. If yes, check the Savvion-level product JDBC configuration. Make changes if necessary.
