Out of Memory Error after Installing the Rev 56 of SAP HANA Studio

[Former Member]

Hi Team,

I'm facing an out of Memory exception while launching HANA Studio after I installed Rev 56 of the HANA studio.

Can you please help us out here, as we need to do some POC on this ?

Thanks & regards,

Hi Jomy,

Can you please try the following:

In file” C:\Program Files\SAP\hdbstudio\hdbstudio.ini” adjust the value for “-Xmx”.

-Xmx1024m

=> java error

Changed to:

-Xmx512m

You should be able to open the studio then.

Hi Jomy

Please do a ./HDB stop and ./HDB start,  you can do that by using putty logging as root user and changing the user in to hdbadm.

Flow should be like this:

1. Log-in as a root user using putty.
2. switch to hadbdm user using :   su - hdbadm
3. ./HDB stop    -- this will stop the hana server
4. ./HDB start   --  to start the hana server.

Then check for the Out of memory error - hopefully it will not show up again.  "Also Out of Memory Error is at OS level"

Fro more detail you can refer to the comments of these two documents  http://scn.sap.com/docs/DOC-42451 and  http://scn.sap.com/docs/DOC-30980#comment-361993

Hi Kumar

The error message is for SAP HANA Studio and not for the server.

Re-starting the HANA server wouldn't fix anything about this problem but only get your HANA server restarted (downtime!).

From what we see, the problem seems to be that the 32-Bit version (with reduced memory address room) is used and the initial memory allocation pool is set a bit high.

So Ravis hint might work well to work around this.

Hi Lars,

thanks for the information, but when I updated the Server to REV 56, I got the same error that time I accessed Rer 56 server with Rev 48 studio, but after HDB stop and Start, I never received the error again with Rev 48 studio and with Rev 56 studio.

As Ravi has mentioned I tried the same :

My result:

Xmx1024m

=> no java error but studio took long to open and perform any task.

Changed to:

-Xmx512m

=> Worked fine as before.

Kumar.

Kumar,

I totally believe that this is your experience.

However, this is coincidence and not causation.

The out of memory error thrown by the java vm from the eclipse platform has nothing to do with the HANA server.

Hi Lars,

Thanks for the input. I second with you as logically its an studio error, but I still wonder how it got solved in my case.

One more point I found REV 56 studio bit buggy you can refer the screen here ( ) as of now I am using Rev 48 studio with Rev 56 server.

Hi again

Well, the error in the other thread is quite different to the one in the current thread, isn't it?

So, this is not actually comparable.

- Lars

[former_member184871]

yes its different but studio Revision is same i.e .Rev 56. I am not comparing the error but the point is of HANA studio Revision number 

[lbreddemann]

Ok - but then we're cross talking, since I only focus on the actual problem.

I'm not going to hit on specific revisions.
