Hallo list,
We have changed session parameter to 500 for our database (11.2.0.2 running under windows server 2008 64 bit).Next day i can see these errors in the alter log:
Fatal NI connect error 12545, connecting to:
(LOCAL=NO)
VERSION INFORMATION:
TNS for 64-bit Windows: Version 11.2.0.2.0 - Production
Oracle Bequeath NT Protocol Adapter for 64-bit Windows: Version 11.2.0.2.0 - Production
Windows NT TCP/IP NT Protocol Adapter for 64-bit Windows: Version 11.2.0.2.0 - Production
Time: 24-APR-2015 15:35:39
Tracing not turned on.
Tns error struct:
ns main err code: 12545
TNS-12545: Connect failed because target host or object does not exist
ns secondary err code: 12560
nt main err code: 0
nt secondary err code: 0
nt OS err code: 0
opiodr aborting process unknown ospid (1960) as a result of ORA-609
After investigation i found the error is triggered when user SYSMAN tries to connect to the database ,this causes our backup jobs in Enterprise Manager fails,also as a result i can not log on Enterprise manager.
Have any one a cue to the problem? i even reduced number of sessions back to 450 but the error still showing in alter log/
Best wishes to all of you,
