Hi, Last night a database server was rebooted. It has both oracle 8i and oracle 9 databases on it. The oracle 9 database started fine, the oracle 8s don't want to play. I believe I have all the environment variables set for the oracle 8 home. When starting svrmgrl I am getting an ORA-15260: TNS:protocol adapter error. Also the oracle 8 listener is not running. When trying to start the listener errors out with: Failed to start service, error 997. TNS-12536: TNS:operation would block TNS-12560: TNS:protocol adapter error TNS-00506: Operation would block 32-bit Windows Error: 997: Unknown error Another wierd thing, the log files for the listener are being generated in the oracle 9 home. Where is it finding the references to the oracle9 home? Thanks, Jeff -- //www.freelists.org/webpage/oracle-l
