Issue/Introduction

After upgrading to Z/OS 2.03 RSU1812 we cannot compile and link a module using SUBSYS=LAM
To get around the abend we were able to copy the member out of  the Librarian master file  to a temp file and  use that as input to the
 job instead of using SUBSYS=LAM.

Cause

After applying IBM maintenance RSU1812 for z/OS 2.3 APAR OA53955 (Z/OS 2.3) introduced new  DEBCHK ADDLOCK/UNLOCK function which causes jobs using SUBSYS=LAM to fail with DEBCHK errors or SC03 abends on compiles.

Environment

Librarian V4.4 
z/OS 2.3 RSU1812

Resolution

Download and apply Librarian PTF SO04128.
Follow the instructions in the HOLDDATA.
-   Reinit LAM subsystem using CA Common Services rimparms as follows:
   PRODUCT(CA-LIB44) VERSION(LJ44) INIT(LJ44INIT) PARM(REINIT,NAME=LAM)
