Description:
What is the "Sybase Client Libraries" field for?

Symptoms:
n/a

This field is specifically addressed for the Sybase APM for HP-UX that requires additional library to be loaded. Use this field to load the other required library from Sybase APM.

Sybase APM for HP-UX require additional library "/usr/lib/libcl.2" to be loaded. Without this library, Sybase db backup just hangs and no data is transferred to the backup device.

Alternate method is to manually modify the Sybase backup server script (i.e. RUN_<servername>_BS) and activate the environment variable:

=====
#! /bin/sh
#
# Error log path: ............
:
:
# Backup Server name: .............

LD_PRELOAD=/usr/lib/libcl.2
export LD_PRELOAD

<Sybase home>/ASE-12_5/bin/backupserver \
-S<server name>_BS \
-e ............
:
=====

Important: HP-UX OS needs to have adequate patch installed so that the LD_PRELOAD parameter is activated. Run "swlist | grep -i linker" command to see which linker patch version is applied.

* HP-UX 11.0 - requires patch PHSS_24303 or later.
* HP-UX 11i - requires patch PHSS_22535 or later.
