LSB_KRB_TGT_DIR

Syntax

LSB_KRB_TGT_DIR=directory

Description

Specify a directory in which Ticket Granting Ticket (TGT) for a running job is stored. Each job or task will have its environment variable KRB5CCNAME pointing to the TGT file. Please note that this parameter controls the TGT location for running jobs, not for pending jobs on the mbatchd side. For pending jobs, TGTs are stored in the mbatchd info directory, along with their job log file.

LSF tries to find the directory to place user TGTs in the following order:

  1. LSB_KRB_TGT_DIR
  2. /tmp on execution host

Once LSF finds a valid directory, the search stops.

If LSB_KRB_TGT_DIR is not defined to /tmp, LSF will create a symbolic link in /tmp to point to the actual TGT file. The symlink name pattern is lsf_krb5cc_${jid}_${some_suffix}.

Default

Not defined
