Executing CA Fast Unload for Db2 for z/OS (PFU) against tables which were recently encrypted and encountering
the following abends:
USER COMPLETION CODE=0987
PSW AT TIME OF ERROR 078C1000 A6D47AAA ILC 2 INTC 0D

The specific PFU execution include 10 SELECT statements against partitioned
objects with 100+ partitions each.
Release : 20.0
Component : CA Fast Unload for DB2 for z/OS
The following is the Db2 tools for z/OS r20 maintenance located related to encryption
which should be verified as implemented:
SO08313 - OVERALLOCATION OF MEDIA MANAGER'S ENCRYPTION BUFFERS
SO08406 - OVERALLOCATION OF ENCRYPTION STORAGE IN 64-BIT MM INTERFACE
SO08407 - OVERALLOCATION OF ENCRYPTION STORAGE IN 64-BIT MM INTERFACE
SO15937 - USER ABEND 987 (X'3DB') WITH ENCRYPTED DATA SETS
SO15938 - USER ABEND 987 (X'3DB') WITH ENCRYPTED DATA SETS
SO15939 - USER ABEND 987 (X'3DB') WITH ENCRYPTED DATA SETS
Based on the above maintenance, it appears that there is additional storage
requirements for encryption buffers.
The SYSTEM COMPLETION CODE=DC2 REASON CODE=4A001620 abend indicates:
A DC2 abend can be issued for a valid request which cannot be successfully
processed by RSM. DC2 abend are only generated when an IARV64 request is
An IARV64 macro invocation to manage storage above 2 gigabytes failed. The 4
byte hexadecimal reason code is in the format xxrrrryy, where rrrr describes
the error. The following are the rrrr values and their meanings:
Memory limit exceeded.
- If the reason code is memory limit exceeded (0016), determine if the
MEMLIMIT value for the address space can be raised to accommodate its
Recommended specifying a MEMLIMIT=nnnnnG in the JOBCARD.
Possibly try MEMLIMIT=4G or MEMLIMIT=8G on the more complex Fast Unload
jobs with multiple SELECT statements where encryption is in place.
