Example of Adding LUs

The following example shows four LUADD statements in a parmlib member named APPCPM1A. The first LU is similar to the default LU provided in the sample APPCPMXX member in SYS1.SAMPLIB. It is a member of the VTAM® generic resource group MVSLU1, and is enabled for network-qualified names support. The second LU is one in a generic resource group of test LUs that access group and system-level profiles from a special test TP profile file. The third LU accesses user, group, and system-level profiles from the TP profile file SYS1.XYZTP. Following an interruption, sessions in this LU would persist for 3600 seconds (1 hour). If service is not restored within 3600 seconds the LU becomes unavailable. The USERVAR and ALTLU keywords are used to pass data to scheduler XYZ. This XYZ scheduler is a scheduler other than the APPC/MVS transaction scheduler (ASCH). The fourth LU is a NOSCHED LU from which APPC/MVS servers will receive inbound conversations. This LU accesses only the database token from TP profile file SYS1.APPCTP.

To activate the LUs, issue the START command if APPC was not previously started; otherwise issue the SET command. Examples of each command follow.

   START APPC,SUB=MSTR,APPC=1A

   SET APPC=1A
