TS/MP 2.5 System Management Manual

Example 32 Wild card support using * in the SERVER object name
STATUS SERVER EXM*
The above command displays the status of all server classes defined for the PATHWAY environment
whose name starts with "EXM":
INFOERROR#RUNNINGSERVER
1EXMP1
1EXMP2
1EXMP3
1EXMP4
1EXMPA
1EXMPB
NOTE: Only one instance of the wildcard character ("*") is accepted. If two or more asterisks
are used, "illegal syntax" error appears. Therefore, for example, A*BD, AB*D or ABD* is supported.
However, A*B*D or AB**D is not supported.
Usage Considerations for SET SERVER TIMEOUT Attribute
If a server process is delayed in its request processing (for example: when it is stuck behind a lock,
is blocked by a higher priority process, or due to any performance pitfall), TS/MP might time out
the request using the timeout value from either the SET SERVER TIMEOUT configuration parameter
or the timeout argument of a SERVERCLASS_SEND_ call, SERVERCLASS_DIALOG_BEGIN_call or
SERVERCLASS_DIALOG_SEND_call.
Despite being timed out, the server might continue to process the request or continue to be "stuck".
Read-only type processing is especially vulnerable to these conditions.
When insert, update, or delete operations are being performed within a TMF transaction and a
timeout occurs, the TMF transaction will be aborted. Subsequent I/O operations might then complete
with file system error FEINVTRANSID, thereby terminating processing. Read-only processing has
no easy way to know that the server request was cancelled, unless the server is multi-threaded and
monitors $RECEIVE for incoming messages and cancellations while processing its current requests.
If MAXLINKS > 1, any requests queued on $RECEIVE will continue to queue there, possibly up to
the point of timing out themselves. Configuring MAXLINKS 1 for a server class minimizes these
additional effects.
Therefore, a single-threaded server is incapable of processing $RECEIVE “message cancellation”
system messages in a timely fashion.
