Installation Process

Note Some members of the CNTL library are now under SMP/E control and some members will be loaded as part of the APPLY process. When modifying the ALLOCT00 JCL stream, verify that the TCPJCL DDDEF points to your CNTL library. Also, you should exit the CNTL library as soon as the INSTSMPE job stream is submitted. Keeping the data set open in your TSO session will cause the APPLY job to fail.

References to member names in the following instructions are located in the control file that you loaded onto your system in Control File JCL.

1TCPNAMES

Member TCPNAMES in the CNTL library is used to customize all other installation members.

The TCPNAMES member, a REXX EXEC, lets you assign consistent data set name allocations. You can customize member TCPNAMES so that you do not need to edit the other installation members manually.

Step 1 Edit the data set name symbolics to be consistent with naming conventions of your site.

Verify adequate space on the volume specified.

The LNKINDX data set is allocated as a SYS1 data set in job ALLOCT00. You can change to a different high level node if you do not have authority to allocate SYS1.

Step 2 Copy the TCPNAMES member to a CMDLIB listed in the SYSPROC concatenation of your TSO logon procedure as described below.

Determine the name of your logon procedure. It is identified on the first screen of your

TSO logon.

Determine the data set in which your logon procedure is located. It is most likely in SYS1.PROCLIB. If not, from your TSO command line execute the command

TSO LISTA, which will list all data sets allocated to your TSO session. Your TSO logon procedure is most likely located in a data set with final node of PROCLIB.

Determine the CMDLIB you will use. Select the member containing your logon procedure, find the SYSPROC DD, and select a CMDLIB to copy TCPNAMES into.

If you are copying TCPNAMES into a VBA library, you must delete the line numbers that appear in columns 73 through 80 after you copy it in.

2JOBCARD

Member JOBCARD in the CNTL library is used by the TCPNAMES EXEC to customize the jobcards of all other installation members.

Choose a jobcard and copy it into the CNTL data set member JOBCARD.

If you are using JES3, replace the JOBPARM card with the following:

//*MAIN LINES=(999,W)

3ALLOCSMP

Member ALLOCSMP allocates the data sets that contain your consolidated software inventory. Edit and submit member ALLOCSMP according to the instructions below.

Before submitting the ALLOCSMP member, consider the following:

ALLOCSMP requires 53 cylinders.
