Quick Beginnings for DB2 Connect Enterprise Edition
This section describes the SPM processes.
The LU 6.2 SPM has Engine Dispatchable Units (EDUs) with the
following names:
- db2spmcm
- The SPM APPC listener. This is a long-lived EDU that remains as
long as DB2 is started.
- db2spmrm
- The SPM restart/resync manager EDU. This is a long-lived EDU that
remains as long as DB2 is started.
- db2spmlw
- The log write EDU of the SPM Logger. This is a long-lived EDU that
remains as long as DB2 is started.
- db2spmri
- The resynchronization initiator EDU. This is a short-lived EDU that
exists until the resync operation is completed. The number of EDUs of
type db2spmri are controlled by the SPM_RESYNC_AGENT_LIMIT.
- db2spmrr
- The resynchronization receiver or XLN receiver EDU. This is a
short-lived EDU that is spawned by the SPM SNA listener when a syncpoint TP
attach request is received.
In UNIX, these EDU names can be displayed as separate processes.
