Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Feedback on Procwatcher Tool/Script

Just wondering if anybody here has used Procwatcher ( Note 459694.1 ) for troubleshooting.
11.x, the main Procwatcher features would be:

- Monitors hang analyzer wait chains within the database. |
- Gets short stacks, active session, history, and other data for background processes and processes in the wait chain.
Works in RAC and non-RAC.
- Can be used proactively or to monitor the system if some intermittent hang/problem is expected, can be run to capture data for that
- Can also be used to monitor clusterware processes.

In the Procwatcher note itself (Note 459694.1) it says:

Procwatcher is Ideal for...

- Session level hangs or severe contention in the database/instance.
