Hi , I need to write a JCL which reads a messages from a queue and writes into a file. but I want to commit the transaction at some specified intervals say after 100 messages .for example MAXUMSGS for a queue manager is 500 and 501messages are there queue I need to write a JCL to read a messages and write into a file , this call will fail because MAXUMSGS attribute at Queue Manager ,can we handle in JCL so that we commit this transaction at every 100 message

What application / utility are you using in the JCL to do this? The majority of these allow commit points to be set by one method or another.

"I need to write a JCL..."
It appears that you are not a mainframe person.
JCL is a scripting language that causes application programs to be executed. So, there must be a program. The program will decide how many messages to get, and when to commit.
Look to a mainframe person for help with this. |

JCL is not used in an application - JCL runs applications. 
It certainly doesn't read MQ queues or write files unaided.

I know the program can only handles, reading the queue and writing into a file. I know there is only DB2 commit as well, which can be handled in the program.
Do you suggest anything, apart from writing a program, we can handle this situation.
Thanks for your reply sir. |

Are you the original poster, doing some kind of Jeckel & Hyde thing? 
You either write a program that does this (which on a mainframe will require JCL to run) or you use on of the utilities that can do this.
A search in this forum will turn up a number of discussions on the various methods of file<->message along with their pros and cons.
