CA Allocate DASD Space and Placement

Issue/Introduction

Hi.
We just installed z/OS 2.3
Since then, CA-Allocate EOV logic is disabled.
This is also reported by Health Check : ALLOC_VRFY_EOV_X37_SVCS_STATUS
I can't find why or any error message.

Here is part of the joblog :

I thought we installed all required maintenance for z/OS 2.3
Is there any missing maintenance of parameter for this ?


Environment

Release : 12.5

Component : CA Allocate DASD Space and Placement

Resolution

Regarding your EOV problem  please verify if you have PTF SO11680 installed:

PROBLEM DESCRIPTION:                                                      

After applying IBM PTF's UJ00897 (z/os 2.4), UJ00896 (z/os 2.3), and UJ00898 (z/os 2.2), the CA Allocate 'end-of-volume' (EOV) environment willnot be enabled after CA Allocate initialization.                          

SYMPTOMS:

The VAMH0101E is issued since you are running with PLOPT94 set to Y.

Following is from the health check:
VAMH0101E                                                                          

CA Allocate is not configured to utilize available STUB Methodology.               

                                                                                   

  Explanation:  You are running with PLSOPT94 set to (Y) which will cause CA Allocate to attempt to remove the hooks it has at IGGPRE00, IGGDAC02, IGGPOST0 and SVC26 during a REMOVE operation in the order in which they were set.  This process is referred to as LIFO (last-in, first-out).                                                        

The default value of PLSOPT94 is (N), which will cause CA Allocate to leave those hooks in.  This process is referred to as the STUB  process. The STUBs provide anchor points for CA Allocate and are  effectively dormant when the system is not active.                            

System Action:  In the event of a shutdown outside of an IPL, CA Allocate will attempt removal of the hooks it has at IGGPRE00, IGGDAC02, IGGPOST0 and SVC26 using the LIFO Methodology. LIFO removal of one or more of these hooks is likely to fail because of other OEM products you are running with also hook at these places and very likely hooked after CA Allocate hooked.                               

Operator Response:  Notify the systems programmer.                               

System Programmer Response:  Change the value of PLSOPT94 to (N) in the sysparm override member of your CA Allocate parmlib. The new value(s) will become effective the next time you recycle CA Allocate, or you can use a PARMREF operation to dynamically activate the new values.
