Issue/Introduction

When the CA Scheduler ISPF interface is invoked, message "DATACOM NOT ACTIVE" appears.

At this time, both the Datacom MUF, and Scheduler started task are active.

 

Cause

The Scheduler, and Datacom load libraries are defined in the TSO logon proc STEPLIB DD, but they are not in the correct order.  
STEPLIB DD has the Scheduler loadlib, follows by the Datacom loadlib and CUSLIB.
Example:
//STEPLIB DD DISP=SHR,DSN=CAI.SCHED.CAILOAD
//                DD DISP=SHR,DSN=CAI.DATACOM.CAAXLOAD
//                DD DISP=SHR,DSN=CAI.DATACOM.CUSLIB
 

Environment

Release : 11.0

Component : CA SCHEDULER MVS

Resolution

The Datacom CUSLIB is a user-customized libraries and must be searched before the Datacom executable library.  
The correct order is as follows: 

//STEPLIB DD DISP=SHR,DSN=CAI.SCHED.CAILOAD
//                DD DISP=SHR,DSN=CAI.DATACOM.CUSLIB
//                DD DISP=SHR,DSN=CAI.DATACOM.CAAXLOAD

 

Additional Information

From the Datacom/AD manual in the Install section: 
The libraries that are listed for searching must include the following information in the order shown:
1. User-customized libraries that you might have defined for specially assembled and linked tables. For example,
DBMSTLST, DBSIDPR, DDSRTLM, or User Requirements Tables (CUSLIB)
2. CA Datacom®/AD base executable library (CAAXLOAD): CA Datacom®/DB, CA Datacom® Datadictionary™, CA
Dataquery™ for CA Datacom®, CA IPC, CA Datacom® Server, and CA Datacom® SQL
         3. CA Common Services for z/OS base libraries
