Table 7-20 Key-Range States State Meaning wt_tr_ok Server is waiting for routers to accept it wt_quorum Server is waiting for backend to be quorate lcl_rec Local recovery lcl_rec_fail Primary server waiting for access to a restart journal lcl_rec_icpl Getting next journal to recover from lcl_rec_cpl Processed all journals for local recovery shd_rec Shadow recovery shd_rec_fail Shadow server waiting for access to a restart journal shd_rec_icpl Shadow getting next journal to recover from shd_rec_cpl Processed all journals for shadow recovery catchup Secondary is catching up with primary standby Server is declared as standby active Server is active pri_act Server is active as primary shadow sec_act Server is active as secondary shadow remember Primary is running without shadow secondary The State field of SHOW PARTITION /ROUTER can display the following values:
Table 7-21 Router Partition States State Meaning BLOCKED Key range is recovering or awaiting journal access ACTIVE Primary server is ready to accept transactions CATCHUP Secondary server is catching up with primary TAKEOVR Standby take-over is in progress LAGGING Secondary is ready, primary is still recovering
/BACKEND
/NOBACKEND (D)
Displays information about backend partitions; it shows the partition state and low and high bounds. /BACKEND with /FULL provides more detailed information for a partition, giving the current queue depth (transactions active) on a partition. This is useful for determining whether a server is processing transactions correctly.
- Last Rcvy BE: shows from which node recovery information may be fetched.
- Txns Rcvrd: shows the number of transactions actually recovered.
The default is to output brief router and backend information.
/BRIEF
/NOBRIEF (D)
Brief output gives a one-line listing of each partition in the system, showing the partition name, the facility in which it resides, and the partition state. Since space on the line is limited, partition names may be truncated to fit./CLUSTER
/NOCLUSTER (D)
Specifies that the command is executed on all the nodes in the cluster.If neither /NODE nor /CLUSTER is specified, the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered, the command is executed only on the node where the command was issued.
Note
In environments that do not support remote command capability, the /CLUSTER qualifier causes the relevant command to be executed on the local node only. See Section 1.4 for more information./FACILITY
/FACILITY="*" (D)
Specifies the facility name for which information should be displayed.By default, information is displayed for all facilities.
/FULL
/NOFULL (D)
Gives a detailed listing of server partition information.The following items are displayed:
- Key segment low and high bounds
- Counts of the active and free servers bound to the partition
- Counts of the active and recovered transactions for the partition
- The state of transaction presentation - one of active, suspended or suspending
- The current failover policy - one of fail_to_standby , fail_to_shadow or pre_v32_compatibility
The SHOW PARTITION command displays callout server data as backend server data because a callout server uses server, not router, data structures. A callout server actually runs on the router identified for its facility.
/NODE[=node-list]
/NODE=default-node (D)
Specifies that the command is executed on all nodes specified in node-list . If node-list is omitted, the command is executed only on the node where the command was issued./OUTPUT[=filespec]
/OUTPUT=stdout (D)
Specifies that the resulting information is written to the file filespec . If /OUTPUT or filespec is omitted, the standard or default output is used./ROUTER
/NOROUTER (D)
Displays information about router partitions; it shows the partition state and partition low and high bounds. It can be used to quickly determine the current primary node for a given partition. Using /ROUTER with /FULL provides more detailed information, such as the main, shadow and standby servers for the partitions, as seen from the router.Partition bounds are shown as ASCII characters if there is a translation, otherwise as hexadecimal digits. Only the least significant 4 bytes are shown.
The following example shows a router partition.
