ORA-27211: Failed to load Media Management Library after Update to HP DP 6

Question

Hi,
after an Upgrade to Version 6.0 from the Backupsoftware HP Dataprotector i can't run RMAN Backup's anymore, because something is wrong with Linking of the MML.
BS: SLES 8 / Kernel 2.4.21-251-smp
Oracle: 9.2.0.5
I try this RMAN Statement:
RMAN> run
2> {
3> allocate channel 'c1' device type sbt_tape
4> PARMS='SBT_LIBRARY=/opt/omni/lib/libob2oracle8.so';
5> }
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of allocate command on c1 channel at 10/22/2007 16:04:24
ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27211: Failed to load Media Management Library
Additional information: 2
the tracefile (i try RMAN Test with and without PARM Parameter):

Failed to load SBT library /opt/omni/lib/libob2oracle8.so
All Infos i found tells me:
- that i doesn't need to restart the Instance of the Database
- i must only remove the old link in $ORACLE_HOME/lin/libobk.so and take a link new link $ORACLE_HOME/lin/libobk.so to the new Backuplibrary in /opt/omni/lib/libob2oracle8.so
But this doesn't work!
Any usefull Hints?
I always try the RMAN Command's:
CONFIGURE DEVICE TYPE 'SBT_TAPE' CLEAR;
CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE' clear;
Nothing help...
My last Idea ist to reboot the whole Database, but this is a little difficult 8-)

Answer 1

hi,
all Systems are 32 Bit (Database Oracle 9.2.0.5 and DP6.0).
What do you mean with "what is Version DP6" ?
HP Dataprotector 6.0 with Patch DPLNX_00013
thx
