IBM Platform LSF 9.1.3 Fix 29142 Readme File

Abstract

APAR P100917: This fix disables submission host lookup in the job execution sbatchd.

Description

Readme documentation for IBM Platform LSF 9.1.3 Fix 29142 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issue:

Job execution initialization fails if the execution host cannot resolve the submission host.
We introduce following new parameter in this ticket:

LSB_DISABLE_SUB_HOST_LOOKUP
Configured in lsf.conf

Syntax
LSB_DISABLE_SUB_HOST_LOOKUP=Y|N

Description
Disable submission host name lookup when executing jobs. When this parameter is set, the job execution sbatchd does not look up the submission host name when executing or cleaning up the job. LSF will not be able to do any host-dependent automounting.

Default
N. LSF will look up the submission host name when executing jobs
