Environment

Release : 11.4

Component : CA Workload Automation AE (AutoSys)

Resolution

The /tmp directory should have a minimum of 500 MB of space available.

Please check the disk space on /tmp.

If you can not increase disk space on /tmp, you can use following workaround:

# mkdir /ca_tmp
# chmod 777 /ca_tmp
# IATEMPDIR=/ca_tmp; export IATEMPDIR

Launch WCC installation again

After the installation is complete, remove the temporary directory /ca_tmp and unset the IATEMPDIR variable

# rm -rf /ca_tmp
# unset IATEMPDIR

+

Check if /tmp is not mounted as readonly. You can use following command to make /tmp non-readonly:

mount –o remount,exec /tmp
