STATUS Commands
SDRLOG is created when the first DDL operation is replicated successfully. All
replicated DDL operations are logged, even if they do not succeed.
The SDR updater detects if the log fills up and deletes the oldest records, making room
for new records. The SDR update also detects retries resulting in the same error and
does not write a new log entry that would be a copy of the previous one.
The format of the SDRLOG entries is proprietary. Use the READLOG command to
examine the content of the log file. The display is similar in format to the output of the
STATUS UPDATE command described below.
STATUS Commands
Used in conjunction with the EMS log, the STATUS commands provide information on
the state of the participants in the DDL replication:
STATUS MONITOR
STATUS SDR
STATUS RDF
STATUS UPDATE
STATUS *
STATUS MONITOR
STATUS MONITOR or the equivalent, MONITOR STATUS, displays information about
the monitor process and the objects it manages. In the example below, the monitor has
just been started and no replication has taken place yet:
