Re: Cognos on HANA Live
Hello Sai,
there was a similar question in space SAP HANA and In-Memory Computing: Correct answer (Re: Cognos on SAP HANA?) pointed to SAP note 1577128.
As I have no clue, I will move your question to that space.

Re: Repository: Encountered an error in repository runtime extension; Deploy Attribute View: no view attributes
Hi Sakthikumar,
As far as I know this error comes when no column of attribute view is added to output.
It would be good if you can provide few more details of your model.
Best Regards,

Re: Chasing documentation for Smart data access
As an SAP employee, you might be better off asking for the explanation of not documented parameters in an SAP internal forum or directly from the development team.
One thing I can tell you right away is that guessing what a parameter does (even the "obvious" ones) usually doesn't get the correct answer.
enable_remote_cache -> creates a cache on the remote server? creates a cache that is rather remote? caches data for access by remote systems? ...

Re: HANA Merge and Optimize Compression process
Hi Lars,
You mentioned "the compression optimization only is performed when a lot of data has changed - or when it manually asked for", do you know if HANA upgrade will trigger this process automatically?
We upgrade our HANA from SPS07 to SPS10, after upgrade complete, we found HANA performance is very slow due to optimize compression started against multiple big tables we had in HANA, this make HANA system un-usable for hours, do you if there has way to control this behavior?
Thanks,
Xiaogang

Re: HANA Merge and Optimize Compression process
In the past range partitioned tables were compressed to rarely, e.g. BW fact tables. This has changed with SPS 10. So if you mainly see range partitioned tables being compressed, this special improvement with SPS 10 can be the reason. As a consequence you should see a significantly reduced memory footprint. Theoretically you can set the auto_decision_func of the compression optimization back to the previous default value (temporarily), but usually this shouldn't be required.

Re: HANA smart data integration and smart data quality questions post there
HI Hitesh,
thanks for your reply. We have added all authorizations to our ECC data provisioning db user. However, issue remains. Our ECC uses MS SQL db and only existing schema containing DD16S is native SAP schema RAZ (which is ECC SID), There is no SYSTEM schema.
It seems that HANA somehow gets information (or concludes) that table DD16S resides in SYSTEM schema.
Kind regards, Josko.

Debug the calc view
Hi Experts,
I am trying to debug the calc view. Found info in the help.sap.com as choose the performance icon dropdown for debug. Only users with SELECT and CREATE ANY privilege on _SYS_BIC can debug calculation views.
http://help.sap.com/saphelp_hanaplatform/helpdata/en/d5/1dbabf5be34b408b60bc94ec65243e/content.htm
I dont see the debug option in the modelling editor. how to find out whether my user has those privileges for debug and also how to debug a graphical calc view or analytic view?
Thanks,
Prasad

Hi Prasad,
You will find this option at top right hand side. If you are modeler then you will have rights for debug.

KNN Text Classification Execution Time in HANA
Hi folks,
I have a question about the duration of the KNN Text Categorization (TM_CATEGORIZE_KNN function in Text Mining) in HANA.
I have a train (labelled) table which has 24600 records. It has text, maincategory, subcategory columns where maincategory and subcategory are my labels. Additionally, I have another table which has 8095 records to be predicted for each label. When I start the process, it takes about 140 seconds to finish all predictions for 8095 record (both for two labels) and insert the results into one final table. What will happen, when I have 8 million records to be predicted (assuming the train table size will remain same -actually it may increase as well-)? Will it take 140000 seconds which is about 38 hours? Is that normal or is there a way to increase the speed of the process?
Note: I am using aws r3.2xlarge instance type which has 8 cores, 61GB memory, 1x160 GB SSD. Version is 1.00.110.00.1447753075
For this process, I created an outer procedure (KNN_CHURN_TEST_OUTER) which reads unlabelled records from a table, and an inner procedure (KNN_CHURN_TEST_INNER) which makes predictions for a record (I have two labels, so it makes two predictions for each record). For each record, I call inner procedure from outer procedure.
Thanks,
Inanc
Here is the outer and inner procedures.
CREATE PROCEDURE "SYSTEM"."KNN_CHURN_TEST_OUTER" () LANGUAGE SQLSCRIPT AS BEGIN /***************************** Write your procedure logic *****************************/ DECLARE new_text NCLOB; DECLARE id INT; DECLARE CURSOR c_products FOR SELECT "id","text_data" FROM "SYSTEM"."AVEA_CHURN_TABLE_TEST"; FOR cur_row as c_products DO new_text := cur_row."text_data"; id := cur_row."id"; call "SYSTEM"."KNN_CHURN_TEST_INNER" (id, new_text); END FOR; END;

capturing HANA DB growth
Dear Experts,
Recently we have started conversion activities in SAP HANA systems.
Can anyone of you suggest, on how to capture the DB growth. Also we want to capture the Top 100 tables which grew and if possible certain objects too.

Scheduling the Job only once
Hi Experts,
I am trying to schedule a job, but i need to make sure that the job is scheduled only once.
In xscron i mentioned : xscron: "* * * * * * *"
What actually does happen if we enter all the parameters of the xscron as *.
And what should be done in order to schedule the job only once.
Thanks,
Abhishek.
