OS：Windows Server 2008 R2; Versions：OO 9.07 Database: Oracle
OO work fine, but one day customer restart the OO central failed with the below error: "failed to connect to OO database with error：
Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor"
But after they restart the Oracle, and then restart OO, the problem solved.
This problem happened sometimes, So I do not think the configuration has problem.
What's the analysis direction? does anyone encounter the problem before?
