Messages from the Shared Memory Objects File Server under NDB
This section lists the information and error messages that may be
issued when creating or accessing a Shared Memory Objects File Server (FSSM)
under Natural for DB2.
For information on the FSSM, see File
Server – Shared Memory Object in the Database
Management System Interfaces documentation.
Unlike Natural system messages, the explanatory long texts to FSSM
messages and codes are only available in this document, not online.
FSSM messages are written into the JESMSGLG data set of the job or
started task which tries to access a file server shared memory object. A copy
of these messages prefixed by the job name and job number is written into the
JESMSGLG of the Natural Authorized Services Manager.
- Example:
-
JESMSGLG of CICS:
17.05.41 S0405196 FSSM008I NATFSSM attached to Shared Memory for
17.05.41 S0405196 CMFSERV2 at address 00000200_06900000
JESMSGLG of Authorized Services Manager SAGAS292:
17.05.41 S0306804 ASM0401 SAGAS292: DAEFCIA2 S0405196 FSSM008I NATFSSM attached to Shared Memory for
