# WIS_CDQP_DATA_RECACHE_BATCH

WIS and WQS Process Configuration

CDQP updates introduced in 10.4 by CR17048.

## Summary

This attribute defines the number of work items that the CDQP update thread will update in a single operation when updating CDQP field values for a `WIS` process’ queues.

## Applies To

This attribute should be set for a `WIS` process (only).

## Permissible Values

This attribute must be an integer in the range 1000 to 500000.

## Default Value

The attribute is assigned the following default value when the iProcess Engine node is installed.

Machine ID | Process | Instance | Value
0 | WIS | 0 | 5000

## Notes

The `WIS` process’ `CDQP` update thread is used to update `CDQP` field values for work items in its queues following a `swutil QINFO PUBLISH` command, which is under the `SWDIR``\bin` directory. The `CDQP` update thread updates each work item in each queue handled by the `WIS` process, updating `WIS_CDQP_DATA_RECACHE_BATCH` items at the same time.

The `CDQP` update thread obtains the updated `CDQP` field values from the `pack_data` database table, which prevents other processes from updating or deleting any rows in the table that the `CDQP` update thread is accessing.

If you find that performance is impacted after the `swutil QINFO PUBLISH` command, you should reduce the `WIS_CDQP_DATA_RECACHE_BATCH` value.
