Enqueue Server
(R3EnqueueStat)

Enqueue server that provides the enqueue service for the system

   Enqueue Requests
   (R3EnqueueStatEnqReq)

Number of lock requests

   Enqueue Request Rejects
   (R3EnqueueStatEnqRej)

Number of rejected lock requests

   Enqueue Requests Errors
   (R3EnqueueStatEnqErr)

Number of errors that occurred during lock requests

   Dequeue Requests
   (R3EnqueueStatDeqReq)

Number of release requests (DEQUEUE)(

   Dequeue Requests Errors
   (R3EnqueueStatDeqErr)

Number of errors that occurred when releasing locks

   DequeueAll Requests
   (R3EnqueueStatDeqAll)

Number of releases of all locks of an LUW (such as at the end of an LUW)

   CleanUp Requests
   (R3EnqueueStatCleanReq)

Number of releases of all locks of an application server (such as when the server is started or shut down)

   Backup Requests
   (R3EnqueueStatBackupReq)

Number of update calls for which locks were forwarded to the update. The update process receives the lock owner ID of the caller, the caller receives a new lock owner ID.

   Reporting Requests
   (R3EnqueueStatReportReq)

Number of operations for reading the lock table.

   Owner Names
   (R3EnqueueStatOwnerNames)

Maximum number of lock owner IDs that can be stored in the lock table. Lock owner IDs are assigned to a user context or to an update request.

   Owner Names Peak Utilization
   (R3EnqueueStatOwnerNamesPeak)

Maximum number of lock owners that have been stored simultaneously in the lock table.

   Owner Names Actual Utilization
   (R3EnqueueStatOwnerNamesUtil)

Current number of lock owners in the lock table

   Granule Arguments
   (R3EnqueueStatGranuleArg)

Maximum number of different lock arguments that the lock table can contain; locks of different owners or with different lock modes, but with the same lock argument occupy one entry

   Granule Arguments Peak Utilization
   (R3EnqueueStatGranuleArgPeak)

Maximum number of different lock arguments that have been stored simultaneously in the lock table.

   Granule Arguments Actual Utilization
   (R3EnqueueStatGranuleArgUtil)

Current number of different lock arguments in the lock table

   Granule Entries
   (R3EnqueueStatGranuleEntries)

Maximum number of elementary locks that the lock table can contain (each elementary lock occupies one entry)

   Granule Entries Peak Utilization
   (R3EnqueueStatGranuleEntriesPeak)

Maximum number of elementary locks that have been stored simultaneously in the lock table.

   Granule Entries Actual Utilization
   (R3EnqueueStatGranuleEntriesUtil)

Current number of elementary locks in the lock table

   Update Queue Peak
   (R3EnqueueStatUpdQuePeak)

Maximum number of open update requests with locks that has occurred so far

   Update Queue Actual
   (R3EnqueueStatUpdQueActual)

Current number of open update requests with locks

   Total Lock Time
   (R3EnqueueStatTotLockTime)

Total time spent in the critical path of the lock table for lock operations

   Recent Lock Time (per minute)
   (R3EnqueueStatLockTime)

Time spent in the critical path of the lock table for lock operations (in seconds per minute)

   Total Lock Wait Time
   (R3EnqueueStatTotLockWaitTime)

Total wait time of parallel processes before entering the critical path of the lock table

   Recent Lock Wait Time (per minute)
   (R3EnqueueStatLockWaitTime)

Wait time of parallel processes before entering the critical path of the lock table (in seconds per minute)

   Total Server Time

   Runtime of Data Collector
   (R3EnqueueStatDataCol)

Node that is assigned to the data collection method; this is used to monitor the runtime of each data collection

Enqueue Clients

There is one instance with an enqueue service for each system ‑ this instance becomes the central instance of the system because it has this service. This monitoring object contains performance attributes for requests from the other instances to this service.

   <Hostname>_<SysID>_<InstNo>
   (R3EnqueueClient)

Instance name

      EnqueueFreq
      (R3EnqueueFreq)

Enqueue operations (logical data locks) per minutes that are coming from another instance to the central instance

Connection to Standalone Enqueue

If the system contains a Standalone Enqueue Server, this subtree provides information about the connection to the application server of this standalone enqueue server.

    <Hostname>_<SysID>_<InstNo>
   (R3HAEnqueue)

Instance name

      Description
      (R3HAEnqueueText)

Version of the standalone enqueue server

      Status
      (R3HAEnqueueStatus)

Status of the connection of the instance to the standalone enqueue server

      ReplicationStatus
      (R3HAEnqueueReplicationStatus)

Together with an enqueue replication server, the standalone enqueue server forms a high-availability enqueue server. If a replication server is installed, its current status is displayed here.

      ReplicaAvailability
      (R3HAEnqueueReplicaAvailability)

Availability of the replication server. If the server is not installed, the node contains the value 0%.

      Log
