Step 31. Prepare Control-O

1. Modify installation parameters

   If necessary, modify the Control‑O current release installation parameters. Verify that the values assigned to the following parameters in the current release installation are suitable for production. You can change the values by using the "CTOPARM Post‑Installation" major step, under Product Customization for Control-O, in ICE Customization.

   Table 20 Control‑O installation parameters

   Parameter	Additional considerations
   DAYTIMEO	This definition must kept in the active Control-O
   EMCSCONS	The definitions of the Extended MCS must not conflict with those of the other active Control‑O system. For example you should ensure that test and production installations on the same MVS image do not use SMFID as the prefix of the consoles’ names. ensure that in a Sysplex environment no two installations use the IOA subsystem name as the prefix of the consoles’ names.
   JCMDSSN	This definition must not conflict with that of the other active Control‑O system.
   NUMCONS	If EMCSCONS is assigned, this is unnecessary.

2. Save parameters

   Save parameters by performing the "Save Parameters into Product Libraries" minor step.

3. Check blocks

   Check the KOATERM blocks in the IOAKPRM member in the IOA.PARM library. Verify that all CPUs defined in the IOACPRM member (in the IOA.PARM library) are also defined for KOA.
