SET PARTITION
/IGNORE_RECOVERY
/NOIGNORE_RECOVERY (D)
Forces the partition to exit any current wait state it may be in.
If a partition should enter a wait state or fail because of the unavailability of
either a local or remote journal, this command can be used to override the default
RTR behaviour. It instructs RTR to skip the current step in the recovery process.
Since this command bypasses parts of the recovery cycle, use it with caution, and
only when availability is more important than consistency in your application
databases.
/PRIORITY_LIST=(backend-node-list)
Sets a relative priority that is used by RTR when selecting a backend member
to make active. Enter a list of the backends in your configuration in decreasing
order of priority; the relative order of the list will be taken into consideration
when RTR is determining on which node to make a partition active.
It is not an error to enter different versions of the priority list at different
backends, but this is not recommended. It is recommended to suspend partitions
before changing the priority list.
/RECOVERY_RETRY_COUNT=n
The recovery retry count indicates the maximum number of times that a
transaction should be presented for recovery before being written to the journal
as an exception. Once a transaction has been recorded as an exception, it is no
longer considered eligible for recovery and will require manual processing by a
qualified individual.
The recovery retry count is partition specific, and applies to both local and
shadow recovery operations. The default is no limit on the number of retries,
which permits a killer message to bring down all available servers servicing a
given partition.
The recovery retry count should be set prior to starting (or restarting) the
application servers so that the limit is established prior to the start of recovery
operations.
/RESTART_RECOVERY
Restarts the recovery cycle. The recovery cycle can be manually restarted with
/RESTART. This is useful if the operator previously aborted recovery through
use of /IGNORE_RECOVERY. Since this command may result in recovery of
transactions from previously inaccessible journals, it should not be used if your
applications are sensitive to the order in which transactions are processed by the
servers.
/RESUME
Resume normal operations (that is, cancel a /SUSPEND command). If the
partition is already in the desired state, the command has no effect.
/SHADOW
/NOSHADOW
Turns shadowing on or off for the specified partition.
Shadowing for a partition can be turned off only in the absence of an active
secondary site, that is, the active member must be running in remember mode.
The command will fail if it is entered on either an active primary or secondary. If
entered on a standby of either the primary or secondary, the command is accepted
but fails in the RTR router; this is recorded with a log file entry at the router.
