RMAN 9i backups using EDM [message #74680]

Is anybody using EMC's EDM backup utility with RMAN to back up their Oracle databases? We're running into problems when trying to back up 9i databases. 8i backups work fine.

I have linked my libobk.so library in $ORACLE_HOME/lib to the EDM library and this still odesn't work. I have listed the error I am getting below.

"daily_db_backup.log" 980 lines, 50218 characters
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of allocate command on t1 channel at 02/03/2005 14:36:06
ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27211: Failed to load Media Management Library
Additional information: 2

Recovery Manager complete.

Any help would be much appreciated

check your LD_LIBRARY_PATH

make sure you have LIBPATH has $ORACLE_HOME/lib follwoed by /usr/lib

Did you bounce the instance?

Hi Mahesh,

Thanks for the reply, These are the setting for LIBPATH and LD_LIBRARY_PATH below.

saprsun02b $ env|grep lib
LIBPATH=/apps/oracle/product/9.2/lib:/lib:/usr/lib
LD_LIBRARY_PATH=/apps/oracle/product/9.2/lib:/lib:/usr/lib

Do you see anything wrong with this? I have not bounced the instance, I can't see why this would make a difference as RMAN connects to the target database fine, it just has a problem loading the media manager.

I am not very sure...
Mostly the issue is with libobk. It is supposed to be dynamically loaded but sometimes it will not ( cases reported in different vendors NOT JUST SPECIFIC to EMC).
try creating a symbolic link to MML.
something like

goto
$ORACLE_HOME/lib
create a link to /usr/lib/liblsm.so and call it libobk.so

ln -s /usr/lib/liblsm.so libobk.so

try again.

Hi,

there was no /usr/lib/liblsm.so file, the only file similar was /usr/lib/liblsm.so.1 so I linked this instead(command below) and this still didn't work.

ln -s /usr/lib/liblsm.so.1 libobk.so

Don't really know where to go with this one now.

Cheers,
Dave

is that a 32bit os or 64 bit os?

for 9i
64 bit libraries are in lib and
32 bit libraries are in lib32.

please go this part of documentation carefully and see whether it applies to you.
