Issue/Introduction

An ACF89810 error message is seen right after ACF2 initialization. What is causing this error and how can it be fixed?

Example of messages seen in the console:

ACF89888 ACF2 SUBSYSTEM INITIALIZATION IN PROGRESS 
IEF196I ACF89810 UNABLE TO IMPLANT DELETE CDE HOOK 
*ACF89810 UNABLE TO IMPLANT DELETE CDE HOOK 
ACF89890 ACF2 SUBSYSTEM INITIALIZATION COMPLETE 
CAS2031I CA SAF interface initialization complete

Cause

The most common cause of the ACF89810 error message is missing compatibility fixes.

Other causes could be by either picking up old ACF2 Linklib/LPA libraries or not copying runtime library properly.

Resolution

1. Verify that all ACF2 z/OS compatibility fixes are applied. See the z/OS Compatibility Matrix to verify which fixes are required.
   
   
2. Verify that DSN SYS1.NUCLEUS contains module CSVSBRTN in your IEANUCxx member. Make sure it is current by looking for the eyecatcher.
   
   
3. By using TSO ISRDDN or TSO CAMODID verify the RMID of CSECT ACF89CDE in any module related to it. It is included in several other ACF2 modules such as module ACF89SIP.
   
   The RMID should be current based on the version of z/OS. RMIDs as of March, 2026 include:
   
   z/OS 3.1 with IBM PTF OA66032 or z/OS 3.2: LU16693
   z/OS 3.1 base without IBM PTF OA66032: LU09157
   z/OS 2.5: LU10561
   z/OS 2.3: RO95218
   
   Here in an example of locating the z/OS 2.3 ACF2 RMID RO95218 for ACF89CDE in acf2hlq.CAX1LINK(ACF89SIP):
   
   .......-ACF89CDE........AC89CDE#........CMCTABLE...... AC89CDE@...&...0ACFF1MFS

4. Make sure the runtime library is up to date and if copying, that nothing is missing or out of sync.
