In this example 2 CAM queues have a proxy queue (prx) and a big Qlen. A lot of retries are made by cam.
If there are a lot of queues like this, cam.exe could be overloaded by sending a lot of retries to machines which seem not available on network anymore.
Environment
Release : All Client Automation Release
Component : Client Automation
Resolution
In Addtional information section below there is a text of a script. Create a file camclean.bat with content of this text.
Script camclean.bat could be used to remove CAM queues with proxy and with big Qlen.
It could be copied on the machine with problem under C:\Program Files (x86)\CA\DSM\Bin
Then execute camclean.bat
This script removes the CAM queues with QLen greater or equal to 10 and which have a proxy queue.
This script generates a log file : C:\Program Files (x86)\CA\DSM\logs\camclean.log
This script could be executed regularly on the server (once a day for example).
To do this an Asset Job could be created for this script :
1- On DSM Explorer, create a new Asset Job of type "Command"
2- Give it a name and copy/paste the content of file camclean.txt
3- Click on "Set Scheduling" option.
In Conditions put "Run only once a Day".
4- Click Finish and assign this Asset Job to the machine with cam problem.
Everyday when AM Agent plugin is executed, machine will execute the camclean job and does the cleanup in CAM queues.
