Problem with Patch installation of Dstx

[bhushanpatil]

We faced a strange problem as described below with our major code release in past few days

Problem: Initially we were using custom build c libraries to handle the opeartion to be performed on MQ server of our backend database. but we redesign the architecture and we remove those c libraries and we make use of inbuilt IBM Websphere MQ(Server) adaptor of datastage TX.
In the initial phase this adptor was not working with our application and we got resolution to this by a patch of DSTX 7.5. With the patch we compiled our architecture code libraries and it started working fine on the test UNIX boxes with the DSTX maps deployed on UNIX box.
but when we install the patch on the actual run time production box we faced a problem. In the box we have several instances ( C executables - we called then servers) which inturn are calling some runtime shared object libraries and DSTX maps deployed on UNIX platfroms to perfrom the complete operation . once we install a new patch on the production boxes all instances goes down , then we try to restart some of the instances of our interest. but some instances becomes active while for some instances we were not able to make them working again. then we reboot the complete unix box and then the patch starts working fine. We are just looking for the root cause of this. Can anyone suggest that . Thanks

Without knowing what the patch does it's impossible to say. I think you need to raise it with support as there are obviously other issues asociated with the change.

The patch in the sense we modify some libraries (.so files) in our box. Initially the inbuilt IBM MQServer adaptor of DSTX was not working and the response time of the maps was not that much compatible as compared with the C libraries. So we modify the libraries given by Owner of the product to make this thigs effect. but we faced above mentioned problem. Please suggest. Thanks
