Jobs running via datastage application takes longer than usual
VMAX is the storage array and in our environment there will be day to day clone jobs and followed by some application level jobs. There is an application called Datastage which takes input from one server and manipulates that data and writes it to other server. Let say server A has the application datastage running it uses data from server B and manipulates then writes it to server C. Server A has all thick FC (RDF1+R5). Server B and C devices are all thick FC R5. So this job of datastage is taking longer than usual to complete since last month,it takes atleast 2 hours extra to complete. The application guys are looking at their end but if need to checked at storage level what indicators need to be taken into account to know any performace impact at storage level. Please help me with your suggestions and let me know if you need any information further. Cache WP% stays well below 20 % and there are some spikes here and there.

Hi,
Sorry for the late reply, the issue has been fixed couple of days back and it was on database side, it has been found some log file has exceeded the limit and by purging that log file the issue got fixed.
Thanks for the reply.

You notice the issue the last month.
What has changed the last month or the month before the last month?

Hi Bourne,
at what time all those datastage procedures are executed?
What other procedures are being executed at the same time?
Maybe a DCP must be setup for the devices of the datastage.
