Examples of Modifying an LU

In the following example, the first LUADD statement in parmlib member APPCPM2A defines LU Z098AP01, and the second LUADD statement in APPCPM2M changes the TP profile file for the LU.

Figure 1. APPCPM2A

   LUADD
     ACBNAME(Z098AP01)
     SCHED(ASCH)
     GRNAME(MVSLU1)
     NQN
     TPDATA(SYS1.APPCTP)
     TPLEVEL(SYSTEM)

Figure 2. APPCPM2M

   LUADD
     ACBNAME(Z098AP01)
     SCHED(ASCH)
     GRNAME(MVSLU1)
     NQN
     TPDATA(SYS1.NEWTP)
     TPLEVEL(SYSTEM)

Assuming that parmlib member APPCPM2A is already active, you can modify the LU by issuing the SET command as follows:

     SET APPC=2M

You can also modify the level of an LU through a parmlib member that contains the original LUADD statement with a different TPLEVEL parameter. The following LUADD modifies the level of the LUADD in parmlib member APPCPM2A from SYSTEM to USER.

Figure 3. APPCPM3M

   LUADD
     ACBNAME(Z098AP01)
     SCHED(ASCH)
     GRNAME(MVSLU1)
     NQN
     TPDATA(SYS1.APPCTP)
     TPLEVEL(USER)

Regardless of whether parmlib member APPCPM2A or APPCPM2M is active, to make the change, issue the SET command as follows:

     SET APPC=3M

If after several modifications, you are unsure of what your configuration looks like, issue the following DISPLAY APPC command.

   DISPLAY APPC,LU,ALL

Assuming you created and modified LUs using the previous examples and sessions were bound, you would see the following:
