Report on HANA Views as Data Source Throwing Server Error

[Cognosy]

Hi,
Certain report could not run because a server error occurred. PFB for detailed error. Could somebody direct me the approach to debug the same.

Hi,

I'm not an expert on SAP Hana by any stretch of the imagination, but googling "SAP DBTech JDBC: [2048]: column store error: search table error:  [9] Memory allocation failed." points to this being an error from Hana telling you it is out of memory.

http://sapkbs.blogspot.com/2016/02/1999997-faq-sap-hana-memory.html

I'd be looking at your Hana indexserver trace files to see what they are saying, and also asking SAP support if they can help you with this. I have seen a couple of posts online saying that people with this error have been successful by moving to a newer Hana revision, too, so it might be a limitation of the revision you are using? Bottom line is that this isn't a Cognos error - it's Hana running out of memory. My guess is the report is trying to retrieve a huge amount of data?

Good luck!

MF.

Thank you very Much. Resolved

What did you do to fix the issue? Might be useful to others in the future with the same problem if you can point them in the right direction?

Cheers!

Hi,
I talked to the BASIS team to allocate more memory. Also since I was loading all the data in the prompt page, the Query was taking longer memory hence more time to load.
1. Allot more memory
2. Run only the required queries
