Thanks for the reply. Would the TCA address + tasknum of the current task make for a good unique identifier?

UEPURID will have the value of the local UOW which will change when we create a new UOW during a mid-task syncpoint. So it does not sound useful for your purpose.

Does a given task define a single unique UOW value in UEPURID for the life of the transaction, or can there be multiple UOW values during a single transaction?

I’m looking for a unique identifier at trans start TRUE invocation which can be deduced during the trans end TRUE invocation for the same task.

Thanks.

We give two fields related to the UOW’s identity to the TRUE.

UEPURID is the ‘local’ UOWID which is simply a STCK taken when the unit-of-work is initialised. STCKs are unique within an LPAR, but you might get identical STCKs generated on different LPARs.

UEPUOWDS is the (typically 27 byte) network-qualified UOW id (aka the LU6.2 UOWID, but every UOW has one not just those involved with LU6.2). This is made up of the VTAM network and netname of the region, a portion of the local UOWID and a sequence number. So this WILL be unique within a plex.

CICS uses the network-qualified UOWID a lot of the time (eg if resync is performed).

I have a question about CICSPLEX with respect to UOWID, the Unit of Work Id.
The UOWID is a unique id acquired via the STCK instruction. It is created by CICS and passed to a Task Related User Exit.
Under CICSPLEX, will the UOWID be unique across CICSs?

Hi Roger,

You don’t need to define a PORT in the TCPIP profile, but if you do want to reserve the port to your WUI Server, then the third operand (where you have OMVS) would be your WUI server jobname.

Cheers… Grant

Hi,
A port number is required to specified for WUI. Would you please tell me what is the correct unique port statement to be defined in TCP/IP profile.

9000 TCP OMVS is this correct or not?

I will be appreciated for your reply.

Regards,

Roger Lin

Hi Roger,

if you’re running CICS TS 3.2 you should be able to run CICSPlex SM as well. The CICS InfoCenter has some checklists as to what needs to be done to activate CICSplex SM. At a minimum you will need a CMAS (CICSPlex SM Address Space) which will manage the CICSPlex, and a WUI (Web User Interface) that is used to interact with CICSPlex SM.

The InfoCenter has instructions to get CICSPlex SM installed and verified. There is then a learning path called “Installing CICSPlex SM – WUI scenario” which takes you through defining more and more CICS regions, CMASes and links between them.

You can use CICSPlex for monitoring CICS regions, for performing operations (like changing connections and files to open or closed), for defining resources (using Business Application Services) and for Workload Management between CICS regions too.

Hope OK,

James (CICSPlex SM System Test in Hursley)

Hi,

We are running CICS/TS 3.2. What is the minimum requirement to run CPSM? I heard MVS/TSO ISPF end user
interface is not available in CICS/TS 3.2. If this is true, then does WUI become the way to interface to CPSM?
I do not have any experience in CPSM. We are thinking
to implement CPSM. Any answers or comments are appreciated.
