WIS_LOCK_POOL_SIZES

WIS and WQS Process Configuration

Summary

This attribute defines the number of locks in the internal lock pool used by the WIS process.

Applies To

The attribute can be set for a WIS process (only).

Permissible Values

The attribute value must be one of the following:

Value	Meaning
TINY	Sets the size of the internal lock pool. (The actual numbers represented by these values are set internally by iProcess Engine.)
SMALL
MEDIUM
LARGE
HUGE
GIGANTIC
VAST

Default Value

This attribute is not defined on a newly installed iProcess Engine node. In this case, the default value is:

Machine ID	Process	Instance	Value
0	WIS	0	MEDIUM

The attribute only appears in the output of the SHOW_ALL_ATTRIBUTES command if you have explicitly assigned a value to it using the SET_ATTRIBUTE command. The default setting is not displayed

Notes

The WIS process uses pools of locks to reduce its resource usage when handling large numbers of queues and work items. Because these locks are in pools, the resources required for locking do not increase as the number of work queues and work items increases. This attribute is only read when iProcess Engine starts up. Any changes that are made when iProcess Engine is running are ignored.
