Workload management environment variables in DataStage®

These environment variables provide options for setting workload management requirements.

APT_WLM_COMPUTE_PODS environment variable in DataStage

Set the number of pods to split the the job partitions between.

When set to 1, all partitions will be put on the same pod. When set to N, partitions will be split between N pods. When set to a value less than 1, partitions will be striped across as many pods as needed. The default value is -1.

APT_WLM_PARTITION_COUNT environment variable in DataStage

Set the number of partitions to run with for a job that uses dynamic configuration files.

The APT_WLM_PARTITION_COUNT variable defines the number of partitions a job using dynamic configuration files will run with. It overrides the partition count set in the runtime environment for the job. It will be ignored if the job sets APT_CONFIG_FILE.

APT_WLM_PART_MEMORY environment variable in DataStage

Set the amount of memory in MBs that each partition requires to be available on a pod.

If set, historic memory queuing in WLM will be ignored. The default value is -1 which disables it.

APT_WLM_POD_MEMORY environment variable in DataStage

Set the minimum amount of available memory in MBs that a pod requires to run a job.

The default value is -1 which disables it.

APT_WLM_POD_CPU environment variable in DataStage

Set the minimum amount of available CPU in cores that a pod requires to run a job.

The default value is -1 which disables it.

APT_WLM_PART_CPU environment variable in DataStage

Set the amount of CPU in cores that each partition requires to be available on a pod.

The default value is -1 which disables it.

APT_WLM_RES_REQUIREMENT environment variable in DataStage

Set the strictness of the WLM requirements.

You can set the value to soft or hard. A value of soft means that if the requirements are not met after a few attempts to run, WLM will assign the pod(s)which are closest to meeting the requirements. A value of hard means the job will not be allowed to run until the requirements are met. The default is soft.
