Hi,
Pega Platform requires Java to be installed on the application server.
Please find below link to get the support guide.You can get more details at page no 14,15.

Coming to your other question of heap size,RAM etc ,It depends on your prpc version.for example prpc 7.3 should meet below memory requirements
Application Server
1.System heap size is 4 - 8 GB based on monitoring of memory usage and
garbage collection frequency
2.Larger heaps are advisable if your applications allow a high number of concurrent open tasks
3.The minimum host application server memory size is
8 GB:
4 GB heap + 4 GB for native memory, operating system, and buffering
Database Server
1.8 GB minimum RAM
2.A supported version of the JDBC4 driver for your version of the database
3.10 GB minimum initial tablespace set to auto-extend
4.50 MB logfile size — This default size is sufficient for the initial installation,but will need to be
resized to run the application server workload
These details you can get it from installation guide and support guide.Hope you got your answer.Please let me know If you need more details.

Hi Harsh,
Its always the Java JVM that we use with Pega.
We don't manufacture JVM of our own, we only use JVM from different vendor such as Oracle, IBM etc.

I know Pega is using JAVA JVM, but I would like to know is there any difference between these two in terms of configuration like Heap Size, RAM size etc.
Glade that you have responded to my query.

Hi,
Pega is not giving any JVM, it depends on the application server which you are using either oracle Jvm or websphere jvm.

Hi Sudhakar
Glad that you have responded,
Pega JVM mean to say that JVM which is used by Pega, and the JVM which is used by JAVA app, does it have any architectural difference like RAM occupancy or Heap Size occupancy . is there any thing were JAVA JVM require less amount of Heap Size as compare to Pega JVM ?

Hi,
Pega is also a Java application and a platform where you can build your own applications.
The amount of heap that a Java application(whether it's Pega or any other java application) requires depends on several factors like the size of the application and number of active users etc.

See Application server memory requirements section in Pega installation guide to see the heap requirements.
