Post-installation steps for IMS

The Server Option supports TCP/IP access to IMS using the IBM IMS Connect TCP/IP listener and the Mainframe Connect DirectConnect for z/OS Option. To enable TCP/IP access to IMS, use the following procedure.

StepsTo set up TCP access to IMS

  1. Copy the supplied IMS Connect exit, named SYBTRSEX, from hlq.OSC126.IMS.LOADLIB to an APF-authorized library.

  2. Add the name of the APF-authorized library from step 1 to the STEPLIB of the IMS Connect start-up procedure, for example:

    //IMS7HW01 PROC
    //*
    //STEP1 EXEC PGM=HWSHWS00,REGION=7M,TIME=1440,
    // PARM='BPECFG=BPECFG01,HWSCFG=HWSCFG01'
    //STEPLIB DD DSN=IMS710.HWS110.SHWSRESL,DISP=SHR
    // DD DSN=IMS710B.SDFSRESL,DISP=SHR
    //PROCLIB DD DSN=IMS710B.PROCLIB,DISP=SHR
    //SYSUDUMP DD SYSOUT=A
    //SYSPRINT DD SYSOUT=A
    //HWSRCORD DD DSN=IMS710B.HWSRCDR,DISP=SHR
    

    Here, the APF-authorized library is named “IMS710B.SDFSRESL.”

  3. Add “SYBTRSEX” to the IMS configuration member specified in the start-up procedure, for example:

    HWSCFG01
    
    HWS (ID=IMS71B01,RACF=Y,XIBAREA=20)
    TCPIP (HOSTNAME=TCPIP,ECB=Y,RACFID=DEFAULT,PORTID=(8880),MAXSOC=500,
    TIMEOUT=30000,EXIT=(SYBTRSEX))
    DATASTORE (ID=IMSB,GROUP=IMSXCF,MEMBER=IMSHWS1,TMEMBER=IMS7B)
    

    Here, “SYBTRSEX” is added to the HWSCFG01 member of IMS710B.PROCLIB.

  4. Have your DirectConnect for z/OS TRS administrator add an IMS region with the same listener port as the PORTID specified in the IMS Connect configuration member, for example:

    1> exec sgw_addregion IMSB,ophelia,'8880',IMS
    2> go
    

NoteThe DirectConnect for z/OS Option and IBM IMS Connect support only implicit IMS transactions for the Server Option. Explicit IMS transactions are not supported.
