Hi,
We are having an issue in our CICS.
Lets say we have one CICS region which runs two transactions TRAN1 and TRAN2.
TRAN1 is critical and TRAN2 is non critical.
Sometimes when we have a huge influx of TRAN2, the response time of TRAN1 is affected.
Our CICS treats both TRAN1 and TRAN2 similarly.
Is there anyway we could specify in CICS, to give more resources to TRAN1 and make TRAN2 sort of discretionary.
There was a link in IBM mentioning TERMPRIORITY and PRIORITY.
www.ibm.com/support/knowledgecenter/en/SSGMCP_5.4.0/tuning/dfht3tm1.html
Will the values TERMPRIORITY and PRIORITY prevent TRAN2 from starting when the load is high?
Or will TERMPRIORITY and PRIORITY start all the available transactions both TRAN1 and TRAN2, but slow down the run time of TRAN2 if TRAN1 needs resources?
Please let me know your suggestions. Thank you.
Vasanth.S |

We cannot add a delay in the program to achieve this. I mean we are unable to change programs.
The transactions need to be Managed somewhat similar to how WLM manages resources for jobs |

Put tran2 in an AOR with a low dispatching priority? |

Thank you, that would work.
As a last resort we might actually build a new AOR with lower dispatch priority and route all TRAN2 to it :-( |

Or if you have a CICSPlex SM then explore to see if GOR can help to route it accordingly. |
