TNS-12557: TNS:protocol adapter not loadable

Oracle Error : TNS-12557: TNS protocol adapter not loadable

Cause: On some platforms (such as OS/2) protocol adapters are loaded at run-time. If the shared library (or DLL) for the protocol adapter is missing or one of its supporting libraries is missing then this error is returned.

Action: For further details, turn on tracing and reexecute the operation. The trace file will include the name of the shared library (or DLL) that could not be loaded.

Unable to validate Oracle database credentials error"
Environment: Backup Exec 11d Media server running on W2003 R2 SP2

Remote oracle server running on W2003 SP2 running 4 databases (one on oracle 10, 3 on oracle 9)

Note: complete Oracle newbie.

I'm trying to setup the remote backup agent. I start the BE Remote Agent Utility then select the Oracle tab and click the New button. I select one of the Oracle 9 dbs in the Local instance name drop down field and then fill in the name and password of an oracle user with the appropriate rights to backuprestore the Database. I add the name of the media server in the job settings page. When I click OK the unable to validate error appears.


Also in the \Symantec\Backup Exec\RAWS\sqlnet.log file I get the following:

Fatal NI connect error 12557, connecting to:
(DESCRIPTION=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracl e)(ARGV0=oracleORA92A)(ARGS='(DESCRIPTION=(LOCAL=Y ES)(ADDRESS=(PROTOCOL=beq)))'))(CONNECT_DATA=(SID= ORA92A)(CID=(PROGRAM=C:\Program Files\Symantec\Backup Exec\RAWS\vxmon.exe)(HOST=LEO)(USER=hhall))))
