# Purge a Case

To purge one or more cases of a specific (locally hosted) procedure, use the following command:

## Syntax

    PURGE [-P priority] [-d] <node|-> procname <caselist|ALL_CASES|dd_mm_yyyy>

where:

| • | `-P` `priority` specifies the internal message queue priorities. For more information about message priorities, see "Message Prioritizing" in the appropriate TIBCO iProcess Engine (Database) Administrator’s Guide.

| • | `-d` purges cases without triggering events that are set for the `OnBeforePurge` event. The events are triggered before purging the case if running the `PURGE` command without the `-d` option. For more information about the `OnBeforePurge` event, see TIBCO iProcess Modeler Procedure Management.

| • | `node` is the name of the remote host node. Enter a hyphen (`–`) if the procedure is hosted locally.

| • | `procname` is the name of the procedure, including sub-procedures.

| • | `caselist` purges all cases in a given range, whether they are open or closed. Use:

| — | `ALL_CASES` to specify all cases of the procedure.

| — | a comma (`,`) to separate case numbers, and a hyphen (`–`) to specify a range. The caselist must not exceed 255 characters.

For example, the entry `2,5-10` means case `2` and cases `5` to `10` inclusive.

Note | It is more efficient to purge a number of cases using a list rather than running multiple purge commands.

| • | `dd_mm_yyyy` purges all cases terminated up to and including the specified date. The date is specified as the day, month and year numbers (in that order) separated by underscores.

## Notes

If you use a syntactically incorrect `PURGE` command, the utility may not return an error message (in verbose mode) indicating that it could not process the command.

Purging many cases can be made more efficient by setting the `USE_NEXT_MESSAGE_TO_DEQUEUE` process attribute to `1`. This is only of benefit when there is a large build up of messages in the Oracle AQs. See "Message and Mbox Processing Configuration" in TIBCO iProcess Engine Administrator’s Guide for more information.

## Example

This example purges all cases of procedure `HIRING` on the local node.

    PURGE - hiring ALL_CASES

This example purges case `2` and cases `5-10` inclusive of procedure `HIRING` on the local node:

    PURGE - hiring 2,5-10
