Hi Richa, been looking for performance issues related to this case and found a suggestion to run large data generation jobs in Portal instead of Datamaker and also set the following C:\Program Files\CA\CA Test Data Manager Portal\conf\application.properties parameters and restart TDM portal and test.
tdmweb.publish.batchCommit=true
tdmweb.publish.iterationsBeforeCommit=20000
batchCommit=true means that commits to the database are made in batches rather for each row
application.properties file and restart TDM portal and test.
tdmweb.publish.batchCommit=true
tdmweb.publish.iterationsBeforeCommit=20000
batchCommit=true means that commits to the database are made in batches rather for each row
iterationsBeforeCommit=20000 means that commit to the database is done by batches of 20000 rows.
However, being the output a CSV file we don't think it will affect the performance in this case.
