Connecting the TSO attachment facility to a second Db2 subsystem

After you install a second Db2 subsystem on the same operating system, you should connect the TSO attachment facility to that subsystem.

Procedure

To connect the TSO attachment facility:

  1. Add STEPLIB statements to the logon procedure if you are using a separate library for the second subsystem or you are managing two different SDSNEXIT data sets. The STEPLIB statement must be authorized using the authorized program facility (APF).

    A Db2 logon procedure can use only one set of Db2 libraries.

  2. Concatenate the CLISTs by updating the SYSPROC library if you decide to have a separate library for the second subsystem.
  3. Concatenate the DB2I panels by updating the ISPPLIB library if you decide to have a separate library for the second subsystem.
  4. Concatenate messages by updating the ISPMLIB library if you decide to have a separate library for a second subsystem.
  5. Update the ISPF primary option panel (ISR@PRIM) if you decide to have a separate library for the second subsystem.
  6. Grant authorization on both subsystems as necessary.
  7. Specify the new subsystem name on the Db2I defaults panel as required.
