DS_USE_OLD_STATUS_PURGE
Set this environment variable to disable a change to Auto-purge that was introduced in IBM® InfoSphere® Information Server, Version 8.5.0.1, to ensure multi-instance jobs are passed the correct parameters by a job sequence.
If DS_USE_OLD_STATUS_PURGE is set, a timing issue exists
that might cause an instance of a multi-instance job to be incorrectly
passed default parameters.
