I upgraded ACF2 back in preporeation for Y2K and as I recall, when I installed 
toleration I had to restore and reapply my usermods, some of those usermods 
dealt with TSO submit exit processing and CICS signon processing, did you have 
to reject/restore any usermods and if so did you reapply ?

Subject: z/OS 2.3 Migration Story 

Hello Mates, 

I'm unable to figure out root cause of the below issues after z/OS 2.3 
Migration, as Described below 

1. Once we migrated from z/OS 2.3 (With CA ACF2 V16 security product), One 
of the batch job got failed due to security issue with batch ID, where as 
a batch code with TSO SUMMIT command within the batch job, and it failed 
with very first instance after migration, How ever I had reached security 
team to provide the required access, security team had code batch ID with 
JCL attribute then it got completed successfully, but this batch was 
successfully completing in z/OS 2.1 without JCL attribute, must wanted to 
know does any new security rules come along with z/OS 2,3 (hoe ever I had 
applied all CA z/OS 2.3 compatibility fixes as well), now current problem 
is If I move onto production Lpar to migrate, what if all batch ID's fail's 
(Which has TSO summit command coded on it), it will be a disaster, can some 
tell me, these issue had reported in your system and what action you have 
taken to mitigate this issue 

Hence I need your suggestion to mitigate this issue before the next 
migration. 

2. the batch ID had problem with another batch job, where as it was trying 
to write to master catalogue (however I had try to create a new master 
catalogue during migration unfortunately it didn't work out), where as 
Batch ID previous used to write user catalogue but after migration it tried 
to write on master catalogue directly, and previously it didn't had write 
access, only it had read access to master catalogue. 

Need your suggestion find out the root cause of this issue as well. 

Thanks and regards, 
Shashi
