CA Service Management

Hi, we have just installerd Catalog 17.1.0.1 and today we noticed that the forms keeps cached and its making the requests to fail. Cleaning the cache on each PC solves it but we have more than 5k of them. That is really complicated for us because it is going to affect to other websites.

Does anyone knows an alternative to avoid cleaning all the PCs cache?

Regards

Good Morning Sebastian.

From pour Engineering Team, it is understood that:

In CA Service Catalog(SC), Ehcache is used to store and retrieve Java Objects and it is helpful for improving the performance at server side.
It has nothing to do with the browser cache.
An end user has to delete the browser cache manually.
An administrator can create a new message in SC, asking every user to clear his browser cache.
However, this is not similar to SDM pdm_webcache -b, as this message will be shown to every user until administrator removes it from the message list.

Please advise whether you refer to the browser cache indeed?

Thanks for your understanding and kind regards, Louis.

Hi Louis, thanks for your answer!

Yes, I mean the browser cache on the client side. How can I enable that message?

Is it possible to force the server to reload the forms on the client side without cleaning cache?

Good Afternoon Sebastian.

Forcing a browser-cache-refresh? I am not aware of such option.

You can ask the browser-owner?

Kind regards, Louis.

Yes im talking to the operating system specialist too but I have no good news until now.

Regarding to Service Catalog, I was asking if there is a configuration to force that the forms needs to be downloaded again. Or to change the time of keep alive of each cache.

Good Afternoon Sebastian.

Question:
How to disable form definition caching in Service Catalog?

Answer:
Following is the steps to disable the form definition caching:
1. Open the file ehcache.xml located in the following folder USM_HOME/view/conf in a text editor(notepad).
2. Locate the following line
<cache name="system.form.cache" maxBytesLocalHeap="100M" eternal="false" overflowToDisk="false" timeToIdleSeconds="86400" timeToLiveSeconds="120000"/>
3. Change the following values
timeToIdleSeconds="2"
timeToLiveSeconds="2"
4. Save the file
5. Restart the CA Service Catalog service for the change to take effect.
** Please note that it is mandatory to recycle the CA Service Catalog service after the above changes have been made.

Kind regards, Louis.

HI! Yes i already have that configuration but still need to clean cache on PCs 

Not really an alternative to clearing out the local PC cache, but at least a way to streamline it - it looks like there's a few different ways that Group Policies can be configured to get the same or similar result. You can enable the "Empty Temporary Internet Files Folder when browser is closed" option, manually set a registry entry in HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Cache Persistent = 0, or manually clear out the cache folder through a batch script called at logon. (A modification of the folder-clearing script could likely also work for non-IE browsers like Chrome and Firefox.) More details on how to accomplish these were found at the link below:
