Deploying AEM to Cloud Foundry


Level 1

Wondering if someone maneged to deploy AEM to cloud foundry type of cloud?

I've maxed out on memory for a given instance

       Memory Settings: -XX:MaxMetaspaceSize=838860K -Xms6G -XX:MetaspaceSize=838860K -Xss1M -Xmx6G 

but still getting

Has anyone managed to solve it ?

How much RAM does the server have on which you deployed AEM?

Please share the RAM size, if machine is 32 or 64 bit ?

It's 64bit

 Using 64bit VM settings

It has 8GB memory available on this container.




so yo have 8GB in total and you are allocating 6GB to AEM? I usually go with 50% of memory allocated to the AEM.

It really depends on what you are using this instance for to decide how much total and allocated RAM you need, the more RAM you have the better, as AEM can then run the repository in memory. Remember that AEM now utilises memory mapping[0].  If I had 16GB memory on my machine I'd maybe start 6-8 and see how things run. If I had more than 16GB, I still wouldn't go above 8-12GB.

Are you doing any DAM ingestion?As you need to have an adequate temp drive setup[1]
