IVT5593I

Explanation
 CSM creates a CSM64001 data space for 64-bit backed
fixed data space storage and a CSM31002 data space for 31-bit backed
fixed data space storage. There is not enough storage available in
the existing data space. CSM creates another data space, dspname,
and issues this message.
dspname is the name
of the recently created data space.

System action
 Processing continues.

Operator response
 Issue the DISPLAY CSM command
without the OWNERID operand to determine current storage limits and
usage. Issue a DISPLAY CSM command with OWNERID=ALL
to determine how much storage is in use by each application. If TCP/IP
is available, issue the D TCPIP,,STOR command to
determine its storage usage. Save the system log and request a dump
of VTAM® and TCP/IP address
spaces and CSM data spaces for problem determination. Contact the
system programmer.
Note: CSM data spaces are associated with the
address space 1 (Master Scheduler).
See DISPLAY
CSM command in z/OS Communications Server: SNA Operation for more information.
See DISPLAY TCPIP,,STOR command in z/OS Communications Server: IP System Administrator's
Commands for more information.

System programmer response
Look at the Display CSM command
output and determine which application is using excessive data space
storage including 64-bit or 31-bit back fixed data space storage.
See the APARs II12657 and II12658 for VTAM and
TCP/IP maintenance for CSM storage problems.
If external trace
is active, see Analyzing storage in z/OS Communications Server: SNA Diagnosis Vol
1, Techniques and Procedures for information about analyzing storage by
using the VIT analysis tool.
See Internal
and external trace recording in z/OS Communications Server: SNA Diagnosis Vol
2, FFST Dumps and the VIT for more information.
If TCP/IP indicates
excessive CSM data space storage usage, see Steps
for reviewing a storage problem in z/OS Communications Server: IP Diagnosis Guide for more information.

User response
 Not applicable.

Problem determination
 Not applicable.

Module
 Use the modifiable VTAM start
option MSGMOD=YES (f  procname,vtamopts,msgmod=yes
or f procname,msgmod=yes) to display the issuing
 module when a message is issued. See z/OS Communications Server: SNA Operation and z/OS Communications Server: SNA Resource Definition
Reference for more information about start options.

Automation can be written to complete the following
operations when message IVT5593I is detected:Issue the DISPLAY CSM command without the OWNERID
operand
Issue the DISPLAY CSM command with OWNERID=ALL
Issue the D TCPIP,,STOR command
Request a dump
