RMS_CONPOLICY is a system parameter that specifies the policy to be used for dealing with high-contention write-shared files. This dynamic parameter can be used to ensure fairness between lock conversions and new lock requests.
Possible values are the following:
|NEVER||(Default) Never use the higher overhead option to improve fairness for any write-shared files accessed on the system; minimal overhead.|
|SOMETIMES||Use this option for fairer bucket access (but higher overhead) to any write-shared files with global buffers enabled that are accessed on the system.|
|ALWAYS||Use this option for fairer bucket access (but higher overhead) to all write-shared files accessed on the system.|
You can set this system parameter with the DCL command SET RMS_DEFAULT/SYSTEM/CONTENTION_POLICY=value and display the parameter with the DCL command SHOW RMS_DEFAULT. RMS_CONPOLICY is a DYNAMIC parameter.
