TIBCO StreamBase® Runtime Administrator provides these different views of partition status:
Cluster wide summary
Details on a specific partition
Node summary
Figure 6.4, “Cluster partition summary” shows the cluster
partition summary screen that is accessed from the High
Availability Partitions
folder in the Cluster
Browser
. This screen provides a summary of all partitions that
are defined in every node in a cluster. A row is displayed for each node
with that node's view of the partition. The fields in the
Partitions
table are:
Reporting Node - the node name that is reporting the information on the partition.
Partition Name - the partition name.
Partition State - the state of
the partition on the node in the
field.Reporting
Node
Partition Status - the status
of the partition on the node in the Reporting Node
field.
Last State Change Time - the
last time the partition state changed on the node in the Node
Name
field.
Active Node - the active node
for the partition from the perspective of the node in the
Node Name
field.
Replica Nodes - the replica
nodes for the partition from the perspective of the node in the
Node Name
field.
Replicate To Existing - defines
whether replication occurs to active replica nodes during a migration
(true
) or not (false
).
Object Batch Size - number of objects locked during a migration or update of this partition.
Number of Threads - number of threads used during partition migration.
Restore From Node - node partition should be restored from in a multi-master scenario.
Mapped Types - list of types mapped into this partition.
Broadcast Definition Updates - broadcast changes in partition state to all nodes in the cluster.
Foreign Partition Audit Option - audit node list if a foreign partition.
Replica Audit Option - audit behavior for partitions with replica nodes.
Remote Enable Action - Control remote enabling of the partition.
Availability Zone - the availability zone for the partition.
This information can also be displayed using this command:
epadmin --servicename=X display partition
Figure 6.5, “Partition summary” shows the partition
summary screen that is accessed by selecting a specific partition under
the High Availability Partitions
folder in the
Cluster Browser
. This screen provides a summary of a
specific partition defined in the cluster. The fields in the
Active Node
section of this screen are:
Node Name - the node reporting this information.
Active Node - the active node for the partition.
Partition State - the state of the partition on the active node.
Partition Status - the status of the partition on the active node.
Last State Change Time - the last time the partition state changed on the active node.
Replicate To Existing - defines
whether replication occurs to active replica nodes during a migration
(true
) or not (false
).
Object Batch Size - number of objects locked during a migration or update of this partition.
Number of Threads - number of threads used during partition migration.
Restore from Node - node partition should be restored from in a multi-master scenario.
Mapped Types - list of types mapped into this partition.
Broadcast Definition Updates - whether partition definition updates should be broadcast to other nodes in the cluster.
Foreign Partition Audit Option - the foreign partition audit option value.
Replica Audit Option - the replica audit option value.
Remote Enable Action - the remote partition enable option value.
Availability Zone - the availability zone for the partition.
The Replica Nodes
section of this screen has a
row for each replica node defined for the partition. The fields in this
section of the screen are:
Node Name - this node is a replica node for the partition.
Partition State - the state of the partition on the replica node.
Partition Status - the status of the partition on the replica node.
Type - indicates whether the
partition uses Asynchronous
or
Synchronous
replication to this node.
Last State Change Time - the last time the partition state changed on the replica node.
The information in both of these sections can also be obtained using this command:
epadmin --servicename=X display partition --name="Z"
Figure 6.6, “Partition node summary” shows the node
partition summary screen that is accessed from the High
Availability
tab in the node display. This screen provides a
summary of all partitions that are known by the node in the Known
Partitions
section. A row is displayed for each partition known
by a node. A partition is known by a node when the node is the active or
replica node for a partition, or the partition was previously an active or
replica node, but the partition was migrated off of the node.
The fields in the Known Partitions
section
are:
Partition Name - the partition name.
Partition State - the state of the partition on this node.
Partition Status - the status of the partition on this node.
Last State Change Time - the last time the partition state changed on this node.
Active Node - the active node for the partition from the perspective of this node.
Replica Nodes - the replica nodes for the partition from the perspective of this node.
Replicate To Existing -
defines whether replication occurs to active replica nodes during a
migration (true
) or not
(false
).
Object Batch Size - number of objects locked during a migration or update of this partition.
Number of Threads - number of threads used during partition migration.
Restore From Node - node partition should be restored from in a multi-master scenario.
Mapped Types - list of types mapped into this partition.
Broadcast Definition Updates - whether partition definition updates should be broadcast to other nodes in the cluster.
Foreign Partition Audit Option - the foreign partition audit option value.
Replica Audit Option - the replica audit option value.
Remote Enable Action - the remote partition enable option value.
Availability Zone - the availability zone for the partition.
This information is also available using this command:
epadmin --servicename=A display partition --name=Z
