Re: Delta Merge Duration

Hi Mahesh,

 

In general, for larger tables Delta merge in system generally utilizes more resources and creates a heavy load on the system. Let me try to explain how it calculates.

 

1. It is generally based on number of merge tokens

 

2. Each merge token uses one CPU

 

3. load balancing cost function (load_balancing_func) determines the actual number of available merge     tokens

 

4. The number of token that needs to be will be calculated by system.

 

5. By default, there will be two tokens available for each tale.

 

Coming to your case, You can try start troubleshooting in this way

 

** TRY IN DEV/QUALITY SYSTEM BEFORE TRYING IN PRODUCTION **

 

1. Try to perform manual delta merge and check if it is taking the same time.

 

2. Change the value of default value of token_per_table to 1 and check if it is helping.

 

3. Try reducing number of parallel threads in system and perform manual merge for the same table and check if those are help full.

 

4. You can activate some trace on that and see if there is an issue with the table.

It took only 1.35 sec for me to fetch these details. Yes, I belive there should be some issue with the system. Hopefully, you will get the result in ms in your new hardware

Hello Deniz,

 

You can use below sql scripts in SQL Console;

 

select MANDT, BNAME, BCODE, PASSCODE, PWDSALTEDHASH, UFLAG from [SID].[sid].USR02 where BNAME IN('<Username Password known>', <User name password unknown>)

 

update [SID].[sid].USR02

set PWDSALTEDHASH = (SELECT PWDSALTEDHASH FROM [SID].[sid].USR02  WHERE BNAME = '<Username Password known>' AND MANDT ='000')

where BNAME ='<User name password unknown>' AND MANDT = '100'

 

update [SID].[sid].USR02

set PASSCODE = (SELECT PASSCODE FROM [SID].[sid].USR02 WHERE BNAME = '<Username Password known>' AND MANDT ='000')

where BNAME ='<User name password unknown>' AND MANDT = '100'

 

update [SID].[sid].USR02

set BCODE = (SELECT BCODE FROM [SID].[sid].USR02 WHERE BNAME =  = '<Username Password known>' AND MANDT ='000')

where BNAME ='<User name password unknown>' AND MANDT = '100'

Looks like this might actually turn out to be an issue with the version we were on. The VM's that were built we used an early version SPS 11.  Basis guys patched yesterday afternoon and so far no change in performance.

 

I will have to get the patch details but will update this thread with that information if it solves the problem.

 

Thanks for all the responses

Re: Transforming an ISO 8601 timestamp in HANA

Lucas,

 

I've tested on both the ETL (BODS) and HANA side; the HANA version does not recognize the additional "T" and "Z" characters in the format pattern, while in BODS those are accepted and produce the desired results.  It would be nice if there was a notation ("[..]"?) to indicate an optional part of the format when converting input, but I've worked around that.

 

I have another thread tracking the NULL issue (in the BODS section), which has a couple of interesting wrinkles since the functions there treat nulls differently than other characters.

 

Thanks,

  Donn

Lucas,  p.s.:

 

The to_timestamp() on HANA does convert an ISO 8601 timestamp properly only if the format string is not provided; however it does not accept the "T" and "Z" as part of an otherwise valid format (e.g. to_timestamp('2016-01-19T23:45:22.678Z', 'YYYY-MM-DDTHH24:MI:SS.FF3Z') ). 

This action seems counterintuitive to me, leading to the results I am seeing.

Error creating HANA Rules Framework Rule Service

Dear HANA Rules Framework experts,

 

we have been following Noam Gilady's excellent HANA Rules Framework blog with its respective references.

 

With that, we got everything working including a Vocabulary and Rule.

 

However, when trying to create a Rule Service, we get an 258 - insufficient privilege: Not authorized error. It looks as if the HRF framework tries to create a procedure in the SAP_HRF schema:

CREATE PROCEDURE.png

When executing this code from the SQL Console it fails

DBTech.png

with an

 

SAP DBTech JDBC: [411]: invalid table type: Cannot find table type SAP_HRF.bat::Aggregation.OUTPUT.TYPE: line 4 col 30 (at pos 134)

 

Has anyone come across this before?

 

Many thanks in advance

The ALTER statements cannot be run directly from within SQLScript.

To do that, you need to use dynamic SQL ( EXEC/EXECUTE IMMEDIATE).

BoH HANA - DBCON/DBACOCKPIT Connection to External Oracle Database

Dear Experts,

We have migrated ECC  system from Oracle to HANA.

We are troubleshooting a database connection in HANA DBCON/DBACOCKPIT to our external Oracle database.  We had the external database connection working before migration, but in HANA does not seem to connect to the external database.  Details below.

 

We are able to connect to the remote database with tnsping from the HANA server following command, but going through SAP results in 12154 Error.

Re: Calculated column in analytic view - To get the value for power of a variable that is (Variable) to the power of (1/x)

Hi Thiru, Muthuram, Ganapathy,

 

After an analysis with few customers data with SALES_0 and SALES_3 (Excel), it is observed the suggestion provided before is working as per the requirement (Thanks all!) i.e., the operator ^ and **, but I should make use of decimal part of 1/x. Example: 0.25 of 1/4.

 

The error screenshot which I shared before is due to specific case only as shown in the screenshot.

 

Error for Negative CAGR root.JPG

 

And the details are as shown below:

 

Final Analyze.JPG

 

 

When the SALES_3 is negative then the power of 0.25 is giving an error, as a basic mathematics issue that is root of any negative number is an imaginary. This was causing an error!!

 

So, I am thinking to restrict SALES_0 and SALES_3 greater than zero then perform the CAGR operation, else mark it as Zero.

 

Thanks Everyone.. It helped a lot!!

Nachappa S

Hello Mani,

 

I think you should test command tnsping WTKTST in application server and check if it succeeds or not, Oracle client and library should be installed in application server.

Murray, Basically apart from standard system schemas, there are few schema matching with Logon User IDs. Like there is one for my logon id.

 

And almost all the tables like VBAK, VBAP, MARA etc, they all are in my schema and in other schemas as well, so in short almost all the schemas have similar tables.

Hello Ning,

The Oracle client and library are installed in application server, the. tnsping WTKTST was tested working OK from the application server( I wrongly mentioned as HANA server, actually CI  sever connected to HANA  DB).


In debugging ABAP Database Connectivity (ADBC_TEST_CONNECTION), it fails at

Hi Narinder,

 

For every user created on a HANA system, a schema is created with that of the user name. Data can be loaded in to this Schema through different Data Provisioning techniques. These tables might have been loaded through Data Services or SLT (Here you have loading and replication).

 

Each of these tables in these different scehmas are separate instances and a table in ECC can be loaded in to different schemas under the same name but have to be in different schema. If trying to load in to the same schema the records will be appended or the table can be overwritten.


Different users are using the same server that you are using and each one is loading or replicating these tables for their own practice purposes.
