Updater-level Command
RETRY RDF-control
If an updater has a pending DDL operation that it is unable to execute, then RETRY
causes the updater to make a new attempt to execute the DDL operation. Note that an
updater will retry a failed DDL operation every minute. Issuing the RETRY explicitly
eliminates the delay and causes the updater to retry immediately.
In the example below a table cannot be created on the backup because there is
already a table of that name. In such cases, SDR displays errors in the EMS log to
notify the operator that the CREATE TABLE operation could not be performed. The
error is also reported by STATUS SDR or STATUS UPDATER, as shown below in first
STATUS UPDATER.
