Memory requirement for OrgChart to run on NW7.3?

[Former Member]

Dear Experts,

I installed Nakisa OrgChart 4.1 on NW7.3 last friday.

Configured app from admin console and everything was working fine.

Monday morning NW AS java shut down, When I looked in to logs it was complaining about message server unreachable.

As per my investigation, I think memory parameter value need to be increased.

Is there any memory param recommendations for Nakisa app to run on Portal?

Attached are the log files for your reference.

Thanks,

Hardeep

With regards to memory, there are 2 considerations ... total memory on the NW server and the memory allocated to the Nakisa applications.

Total memory on server: Recommendation is now 16GB RAM (in the "VSN41_Environment_Checklist.docx").  Although in the Capacity Planning Guide I saw ("Capacity_Planning_Guide.pdf") starts from 8GB RAM for upto 15,000 users.

Memory allocated: The last Capacity Planning Guide says 6GB of RAM should be reserved for Nakisa applications.  NetWeaver should also be set to specify the amount of memory to be used by the Nakisa application. There are two JVM configuration parameters to consider (initialHeapSize and maxHeapSize)

Setting	initialHeapSize	maxHeapSize
Minimum	½ x maxHeapSize[1]	6 GB
Maximum	Less than maxHeapSize More than minimum initialheap size.	[Server RAM] – [RAM to reserve for OS and other applications] More than minimum maxHeap size.

[1] From NW 7.3 it is recommended to only change the maxHeapSize (the initialHeapSize will adjust automatically)

Instructions on how to change the values can be found in the SAP online help:

Thank you Stephen for your help!

May I know how can I reserve memory for application running on portal?

In this case, how can i reserve memory for Nakisa app?

Thanks,

Use one the link above for instructions on how to set the initial and max heap size variables in the JVM for the Nakisa application(s).
