Symptoms

Unable to create an Oracle client.

Error in the nsrorara.log:

nsrorara-D0 Unable to load Oracle OCI library.
nsrorara-D0 ERROR generated: "Could not load library("/u01/oracle/12c/product/lib/libclntsh.so")" in file "/disks/nasbld/nas62/nw/19.11/remagents/common/ra/ora/oracommon.c" line #784

Cause

There is an Oracle and NMDA architecture mismatch.
The Oracle database is 64-bit, but the 32-bit version of NMDA was installed.

Resolution

  1. Validate the system architecture on the NMDA client host:
uname -m
A 64-bit host reports x86_64. A 32-bit host reports x86 or i686. For additional commands, consult operating system documentation.
  1. Validate the NetWorker client and NMDA installation architecture:
nsradmin
show arch, CPU Type
print type: nsrla
Or use the operating system's package manager commands to check the package versions:

rpm package managed systems: 
rpm -qa | grep lgto
SUSE systems: 
zypper search -i | grep lgto
AIX systems: 
lslpp -L | grep lgto
Solaris systems: 
pkginfo | grep lgto

The bit architecture (32-bit or 64-bit) of NMDA software that is required depends on the architecture of the database or application server being protected. To resolve this issue:

  1. Uninstall NMDA.
  2. Install the 64-bit NMDA version.
