Answer / tkm
1) Perform a bulk load into the target load.
2) If bulk load is already there, check whether the indexes (if any) in the target table are disabled or not.
3) Maybe you can check the configuration file to check how many nodes it is using and switch to a different configuration file having more number of nodes.

Check the DataStage Director job log for jobs which do not show job run statistics and confirm whether the following variable is defined:
APT_NO_JOBMON
If APT_NO_JOBMON is defined and set to value of 1 or true, then it will disable job monitoring and process metadata reporting for parallel jobs.
Confirm the JobMonApp process is up and running:
ps -ef | grep JobMonApp
default ports for JobMonApp is : 13400 and 13401
Both ports must be in listen state.
if you are getting this error: Failed to connect to JobMonApp on port 13401" please restart this service.
[root@ibmiis9 ~]# cd /opt/IBM/InformationServer/Server/PXEngine/
[root@ibmiis9 PXEngine]# export APT_ORCHHOME=`pwd`
[root@ibmiis9 PXEngine]# cd java/
[root@ibmiis9 java]# ./jobmoninit stop
JobMonApp has been shut down.
[root@ibmiis9 java]# ./jobmoninit start
JobMonApp has been started.
