在日常维护中，我们会经常发现，有些请求无法取消，而且占用资源很高。这时候就需要我们从后台用sql语句修改这个请求的状态。

update fnd_concurrent_requests set status_code='X',phase_code='C' where request_id=;

This problem can occur on any platform.

11.0.x - 12.0.x

Symptoms

Unable to cancel a concurrent request out of the queue that is stuck.

Cause

Tried to Cancel a concurrent request. Used the "Cancel Request" button from the Administer > Concurrent > Manager form.

Got the following message:

Request xxxxxx can no longer be cancelled. The Concurrent Manager Process that was running this request has exited abnormally. The ICM will mark this request as completed with error.

Solution

Manually cancel the request out of the queue with the following SQL against the offending

request id(s). This can be safely done while managers are up and running:

SQL> UPDATE fnd_concurrent_requests

SET phase_code = 'C', status_code = 'X'

WHERE request_id = '';

commit;

Note:  To obtain request details prior to cancelling the request, use Note 134035.1 ANALYZEREQ.SQL - Detailed Analysis of One Concurrent Request. When prompted, provide the request id to be analyzed.  This can be useful for determining the reason why the request may be stuck in the queue.
