Post-installation steps

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 (version 12.5.3 and later). To enable TCP/IP access to IMS, use the following procedure.

Setting 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 startup 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, APF-authorized library is named IMS710B.SDFSRESL.

3. Add SYBTRSEX to the IMS configuration member specified in the startup 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
