When using CA Chorus Mainframe Manager (CSM) to install CA Datacom/DB or CA Datacom/AD products, I need to supply the "Operating System: CAW0LINK*" in the "Target Zone Parameters"

In above,  "CAI.CA90CICS" displays as the default value.

How can I find the library to use?

You can also browse the CAIRIM module and check the eyecatcher. 

To browse the found module in SYSVIEW, enter "B" in the Cmd column to the left of that library.

Release:
Component: DB

Look for the first library in the LINK LIST that has the load module CAIRIM and confirm that it is the CA Common Services (CCS) library. 

Typically it is in the CCS hlq.CAW0LOAD library. 

If you have CA SYSVIEW, you can quickly identify the library using the following commands from within SYSVIEW:

Enter SYSVIWQ command: LINKLIST

This will show the list of libraries currently in this Lpar's link list.

Then enter the SYSVIEW command: WHERE CAIRIM

This will cause the link date ("LinkDate" column) to be filled in for any library in the list that has the CAIRIM module.

Example SYSVIEW display for LINKLIST: 

GSVX000P 4.1 CA11 ----------- LINKLIST Libraries ------------ 04/25/16 15:11:23 

Command ====> Scroll *===> PAGE 

------------------------------------------------ Lvl 2 Row 1-31/143 Col 1-79/86

Setname LNKLST00 Status CURRENT IPL CHK Allocations ACTIVE

LLAStat SEARCH AVAILABLE Extents 199 239

Cmd Dataset-Name Xtn Volser APF Org

    SYS1.LINKLIB 1 MVR21A APF PO 

    SYS1.MIGLIB 1 MVR21A APF PO 

    SYS1.CSSLIB 1 MVR21A APF PO 

...etc...

Example SYSVIEW display for WHERE CAIRIM: 

GSVX000P 4.1 CA11 ----------- LINKLIST Libraries ------------ 04/25/16 15:12:06 

Command ====> Scroll *===> PAGE 

---------------------------------------------- Lvl 2 Row 38-68/143 Col 1-79/146

-------------------------------------------------------------------------------

Cmd Dataset-Name Xtn Volser APF Org LinkDate

    CAIPROD.CCS.R141SE.D160118.CAW0LOAD 1 LNKD01 APF PO 12/30/15 

    CAIPROD.CCS.R141SE.D141212.CCCSLINK 1 LNKD01 APF PO 

    CAIPROD.CCS.R141SE.D141212.CCCSLOAD 1 LNKD01 APF PO

...etc...

In this case, the only CCS library with the CAIRIM module showing a LinkDate found is in CAIPROD.CCS.R141SE.D160118.CAW0LOAD.

If multiple entries display with LinkDate, use the 1st library.

You can also browse the CAIRIM module and check the eyecatcher. 

To browse the found module in SYSVIEW, enter "B" in the Cmd column to the left of that library.
