Physical Lock Transition – identify context switches related to acquiring physical locks.
Logical Lock Transition – identify context switches related to acquiring cluster logical locks
Object Lock Transition – identify context switches related to acquiring object locks
For these three rows, % total represents
a collective number of context switches caused by cluster messaging.
Higher values for % total for
this context indicates high cluster message activity. Compare this
number with Number of Cluster Lock Requests to
determine the number of cluster messages per lock request. Query
the monSysWaits monitoring table for more information
about context switches.
Assess your application partitioning if a lock requests creates too many context switches. A higher number of context switches indicates additional requirements for the cluster message buffer. monCIPC may have high values for ReceiveCount and TransmitCount if there is a shortage of CIPC message buffers. Increase the size of the CIPC message buffer to resolve this issue.
