Hello Guys,

I am starting with hana development.

Where can i download the SAP Hana Studio ?

Thanks.

Hi Team,

We have requirement where we want to Export the system schema full data (including indexes , Table , Function etc) and import the same to another schema say system1 .so that if we are going to change any table inside system1 schema ,should not effect the system schema,,,

What will the shortest and simplest method for doing this.

Your suggestion will be really appreciable .

Hello Experts,

Continuing from the below discussion :

SQLscript procedure - Avoid materialisation of Internal tables

and thanks to valuable inputs form Lars Breddemann I was able to zero in on the problem area.

What I learnt in the process(screenshot from planviz attached ) is that two statements take up 99% of time.

I have pasted the two statements below for reference ( I tried my best to better format sql statements for readability as it is not always the best approach to copy past sql statements )

Also, these two statements form the heart of the functional  logic.

This is part of a Revenue allocation code, where revenues ( or costs ) is allocated from  a sender to a receiver -

based on  characteristics from sender and receiver. (join condition ).

Distribution base is used to create the multiplying factor,

and allocation is done using - S."AMT"  * (R."DIST_BASE" / D."DIST_BASE" ) - ( a keyfigure in Receiver is defined as receiver_distbase )

I'm not  a functional expert in this topic, and sharing what I understood from functional expert.

Not going too much into functional topic,

Wanted to understand what is wrong with the below sqls.

I could already see that case statement is a row operation and will slow down the prcess drastically.

also "IN" in join condition which is also a performance glitch.

I understood from functional expert that this is necessary .

these two statements take around 20 seconds each which i feel is a lot  considering data volume.

Any pointers on how I should proceed.??

Thanks in advance.

Best Regards,
Vinay

Hi,

I'm trying HANA Hadoop Integration using SAP HANA SPS09, Hadoop 2.7.1 and HIVE 1.2.1.

I have followed the videos on the youtube (SAP HANA Academy - SDA : Hadoop Enhancements - 1. Creating User [SPS09] - YouTube) and also read the HANA documents (Administration Guide) on this topic.

All I want to do is to follow the video to run WordCount using HANA Hadoop Integration.

So I have assigned all the necessary privileges to the user and created MR Job Archives, Remote Source and Virtual Functions as shown below:

I have created the mrjobs.

Then I have run the two SQLs successfully.

create remote source hadoop_source

adapter "hadoop"

configuration 'webhdfs_url=http://myserver:50070;webhcat_url=http://myserver:50111'

with credential type 'PASSWORD'

using 'user=hduser;password=hdpass';

create virtual function HADOOP_WORD_COUNT()

RETURNS TABLE ("word" NVARCHAR(60), "count" integer)

package DEV."dev.HanaShared::WordCount"

CONFIGURATION 'enable_remote_cache=true;mapred_jobchain=[{"mapred_input":"/data/mockingbird/",

"mapred_mapper":"sap.WordCountMapper",

"mapred_reducer":"sap.WordCountReducer"}]'

AT HADOOP_SOURCE;

Currently I'm experiencing an issue when executing the last step.

So I wish to check the results:

select * from HADOOP_WORD_COUNT();

But then the console gives me these errors:

Could not execute 'select * from HADOOP_WORD_COUNT()' in 74 ms 384 µs .

SAP DBTech JDBC: [2048]: column store error: search table error:  [2620] executor: plan operation failed;

I went to check the log file of my HANA and found these:

pop.setNodeName('$$_SYS_SS2_RETURN_VAR_$$HADOOP_WORD_COUNT')

pop.setUseInternalTable()

Judging from the logs it seems the plan executor fails before the job could be able to be started.

BTW

I can successfully see the controller.jar in hadoop

Also I have uploaded the jars in the lib folder following the administration guide.

I tried different HANAs including SPS09 and SPS10 to perform the integration, all give me the same error.

So my question is has anyone happened to face the same issue?

Or if there is anything wrong with my previous steps?

Thanks in advance.

We have been facing a similar issue after an upgrade to the SPS 10.

Re: Out of Memory when executing Stored Procedures after SPS 09 upgrade

We had to downgrade again to SPS 09 but the issue didn't resolve.

The problem manifested in different ways. The most recent one appeared as it follows.

We have a select statement that goes out of memory when running into a store procedure. On the contrary it works fine when executed from SQL console. The select looks like:

SELECT [CALCULATION VIEW] WHERE [CLAUSE]

We have gone over this plenty of times but still don't understand what is going on here.

According to the PlanViz the engine suddenly starts making outer joins for apparently no reason (find the plv attacched).

Moreover if we get rid of the WHERE clause the execution doesn't run out of memory.

We did open an incident, but we are struggling to get an answer.

Hi All,

We are implementing   sidecar approach & installed below components.

1. HANA Database intallation done.

2. ECC & BW systems went go-live

3. SLT server Installation

Applied required add-ons on ECC side and SLT.

Can you please let us know know  steps needed for Replication of Data from ECC/BW on to the Hana.

Do we need to run any jobs for the same?

Please advice.

Regards,

Karthik.

Hi,

I am unable to find creation date of HANA Views. I looked at "SYS"."VIEW" as well as underlying base table "SYS"."RS_VIEWS_" but could not see a any date field. Where do I find information on when a HANA View was created and last modified? 

(In case of HANA tables, information is available in column "CREATE_TIME" in view "SYS"."M_RS_TABLES" but not for views )

Thanks.

#HANA Gurus

In HANA Studio ABAP Schema user is getting locked automatically.

So I want to know where we can check how the user is getting lock, is there any trace on OS level where we can check this or on HANA side how to find user info.    

Thanks in advance

Hi All,

Has anyone successfully installed SPS11 using the downloads from the service market place?

I have downloaded the files 3 times and each time I am getting CRC errors during the RAR Extraction process. This seems to be leading to issues during my install process.

Any feedback would be greatly appreciated.

Thanks, Paul

Subsequent install issue:

Hello,

I need to prepare a SCM migration to Hana Database, and I've been looking for a guide like as First Steps to migrate BW to Hana for SCM System but I can't find anything.

Are there a similar guide for SCM migration?

Thanks a lot.

Hello Gurus,

A bit of a background , I am developing SAP HANA views, which will be accessed using HANA live Browser or BOBJ.

Now the challenge is the organization has thousands or users and roles,

Is there any way to do a mass migration from ECC into SAP HANA Studio.

Need your urgent attention on this.

Hi, everybody, I'm not sure if this is the right forum, but I'm trying ...

I'm new to HANA xs service and I'm trying to make a databasepool in a xs service. I've done every thing that is listed in the sap HANA Developers Guide sps10, but still I think I got one connection instead of several connection via the dbpool. Here is how I have done it

1. created a .xssqlcc file
2. added description in .xssalcc file
3. added default role in .xssqlcc file
4. activeded the xssqlcc file in repo
5. activated the xssqlcc file via hana/xs/admin console
6. added code in my xs service

             var connDBpool = $.hdb.getConnection({'sqlcc' : '<package:myxssqlcc file>','pool' : true});

But still it seems to be only one db connection, then the service is doing several queries at the same time. Have some of you successfully created a dbpool, have I missed something in the configuration of the dbpool?

Do I also need to add some properties to the .xsaccess file? The content of that file is at the moment

{

     "prevent_xsrf": true,

     "authentication": { "method": "Basic"},

     "exposed": true

}

The reasone for why I want a dbpool is because I find it very strange that  the xs service need to make a db - connection for each and every query to the database.

Hi ,

I have read many forums where the calculation view - Graphical is called in the calculation view - SQL and parameters are passed, in my POC i want to try the other way, I want to use the calculation view - SQL in calculation view - Graphical in the projection node and get the desired output.

Can you please check the attached document and help me to resolve the issue?

Hello, experts.

I have a problem on setting up on Managed System Configuration for SAP HANA on SOLMAN71.

THe environment is

SAP HANA SPS04 revision 28.

Solution Manager 7.1 SR1

I have already done this 2steps "Preparation of Solution Manager", "Preparation on HANA"

http://scn.sap.com/community/it-management/alm/solution-manager/blog/2012/03/30/configure-hana-db-with-sap-solution-manager-for-rca-tools-and-technical-monitoring.

and at the next step,

I have some troubles.

Under the steps Managed Systems Configuration

Technical System -> Configure System ->step 5"Enter Landscape Parameters" -> Landscape Objects

it shows

Installed on path <Not Defined>(HANA Installed Technical System)(1)

and Status is "No parameters" (see the attached file1)

Technical System -> Configure System ->step 9"Check Configuration" -> Configuration Check

Message "Managed System ...~HANADB is not configured"

"No Path found in the Installed Technical System" in detail.(see the attached file2)

---------------------

I already check following URL. and needed procedure is already done.

http://wiki.sdn.sap.com/wiki/display/SMSETUP/Maintenance+of+Product+in+the+System+Landscape#MaintenanceofProductintheSystemLandscape-SAPHANA

and

I tried input the path on Technical System.(see the attached file3,4)

but nothing changed.

Regards.

I’ve a question.

Is it possible, to replicate the HANA database a second one?

Our business is planned a new datacenter design.

It’s planned to have a local HA solution. But the datacenter for the DR solutions, are more than 100km away.

So we will create for the local HA solution a synchronous replication and for the DR scenario an asynchronous replication.

Can me anyone help?

Thanks

Michael
