IWMWQWRK – Query Work Service

A work manager can use IWMWQWRK to help identify where its transactions may be executing. A caller can issue this for a work manager address space that is having trouble executing transactions, and wants to find out where transactions are abending.

A caller can narrow in on where the problem is occurring by using the LU 6.2 token information contained in monitoring environments.

With this service, a caller can get:

• A list of LU 6.2 tokens

  Specify SEARCH_BY=CONNTKN, and get a list of LU 6.2 tokens for all work requests reflected in monitoring environments owned by the current home address space. To do this, the caller should provide the connect token of the address space in the CONNTKN parameter.

• A list of ASIDs and/or STOKENs

  Specify SEARCH_BY=LU62TKN and provide a list of LU 6.2 tokens, and IWMWQWRK returns a list of ASIDs and/or STOKENs representing owners of monitoring environments initialized (via IWM4MINI) with an LU 6.2 token in the list.

  The list of LU 6.2 tokens must have been obtained on a previous call to IWMWQWRK.

  Monitoring environments owned by the home address space which are related (by IWMMRELA) to other monitoring environments are not searched.

  Optionally, to narrow the search, a caller can also provide the subsystem type or the subsystem instance in the SUBSYS and SUBSYSNM parameters.
