DSNA messages

Message identifiers that begin with DSNA communicate information about the call attachment facility (CAF).

DSNA messages fall into two categories:

• Messages that are written to a trace file. These are seen only if the trace is turned on (that is, ddname DSNTRACE was allocated to SYSOUT or the TSO terminal).
• Messages that are returned by a Db2 stored procedure. These are seen only as a parameter that is returned by the stored procedure.

DSNA messages use common elements and share the same basic structure:

• Message number (DSNAnnna).
• The name of the CSECT responsible for writing the message.
• TCB address of the task currently executing.
• A series of tokens and token-explanations unique to each message.

The intent of these messages is to aid IBM® Support. They contain information that might not be meaningful except to IBM.
