11.2 Step 2: Defining VTAM Resources

1. Define LU in VTAM configuration:

   The LU configuration for the remote CICS region should resemble in the following Listing and be located in SYS1.VTAMLIST by default. It is shown in bold typeface where the LU name is used for this remote CICS region.

   Listing LU Configuration for Remote CICS Region

   CRMMN3         VBUILD TYPE=APPL
   **LUNAME**     APPL ACBNAME=**LUNAME**,
                  APPC=YES,
                  SYNCLVL=SYNCPT,
                  AUTH=(ACQ,PASS),
                  PARSESS=YES
   *example ACBNAME=( CRMLU80 )

   Note:

   All entries prefixed and terminated with ** are placeholders for you to fill in with relevant parameters, or take a note of the subsequent configuration entries. It is applicable to all of the subsequent cases and won’t be noted again.
2. Check or define the connection in the remote CICS region:

   The purpose is to add LU to the connection of the CICS region. The value of NETNAME field should be consistent with the LU defined on system A in Step 1: Configuring ART CICS on Open System.

   Note:

   When the same placeholder is identified in multiple entries, please use consistent values, for example, **GROUPNAME**, as in the following listing.

   Listing Define LU Connection for Remote CICS Region

   ADD GROUP(**GROUPNAME**) LIST(**LISTNAME**)
   
   DEFINE CONNECTION(**CONNNAME**)   GROUP(**GROUPNAME**)
          DE(BEA TMA SNA EXAMPLE RDO CONNECTION) 
          ACCESSMETHOD(VTAM)         PROTOCOL(APPC) 
          NETNAME(**LUNAME**) 
          ATTACHSEC(LOCAL)           AUTOCONNECT(NO)
   *example CONNECTION(BEALST)
   *example CONNECTION(BEA)
   *example GROUP(BEACONN)
   *example NETNAME(CRMLU80)
   
   DEFINE SESSION(**SESSIONNAME**)   GROUP(**GROUPNAME**)) 
          CONNECTION(**CONNNAME**) 
          DE(SESSION EXAMPLE)
          PROTOCOL(APPC)             AUTOCONNECT(YES) 
          MODENAME(**SNANAME**)      MAXIMUM(**SESSNBR**,**WINNER**)
   *example SESSION(BEATEST)
   *example CONNECTION(BEA)
   *example GROUP(BEACONN), keep it same as group name in DEFINE CONNECTION 
   statement
   *example MODENAME(SMSNA100)      MAXIMUM(10,5)

3. Activate defined LU resource:

   In SDSF, enter the following commands:

   1. Enter LOG in SDSF.
   2. Enter /V net,id=**Major Node Name**,act,scope=all to activate all LUs defined under this major node. Example below uses crmmn3 as the node name.
   3. Check result, as shown below, the screen shows crmmn3 active
