Re: Error when Exporting on Hana cluster when connecting to secondary

$

Hi Raj,

 

Thanks for your response.

 

For our application we are running the command with jdbc and use the full connection string listing all hosts. When using jdbc we are getting this error whenever we list all hosts. We need to do this because we have a requirement for high availability where an active node (including the primary) could be a failover node.

 

Otherwise we would have to run a query to figure out what the actual primary is and have a different connection url for export from our normal jdbc url.

 

Thanks,

Jason


Re: authorizations trace in SAP HANA

Hi,

 

I guess there is no such equivalent but we can find what authorizations an USER has by querying the table "SYS"."GRANTED_PRIVILEGES" .

 

You can query by Object type,Schema Name, Grantee, etc.

 

In order to find privileges for a particular user, the query will be

 

select * from "SYS"."GRANTED_PRIVILEGES"

where GRANTEE = 'user_name'

Re: Installing HDB Server : hdbnsutil permission denied error

Hi Michael,
depending on which VM solution you are using, you got several problemes. the most importent on is the CMPXCHG16B support.
without it your hana db will not run. you have to activate it in your VM.
check with: grep cx16 /proc/cpuinfo
if your VM cpu is not supportet (usually it's not), you need to adjust a parameter in /i/51046016/DATA_UNITS/HDB_SERVER_LINUX_X86_64/server/HanaHwCheck.py
replace: self.HWInfo['CPU Sockets']=len(lines)-1       
with   : self.HWInfo['CPU Sockets']=<number of cores you want for HANA>
otherwise you get an Division by 0 error during the installation
a lot of erros you get for not supported hardware you can ignore with setting
export IDSPISPOPD=1
before you start the installation
now to your problem. when it aborts with the not enough memory error you have to continue manually.
if you don't want to provide the passwords on the commandline you can also continue interactivly with:
/i/51046016/DATA_UNITS/HDB_SERVER_LINUX_X86_64/hdbinst -s <SID> -n 16 -H penguin16  --datapath=/hana/shared/data --logpath=/hana/shared/log --sapmnt=/hana/shared --ignore=check_min_mem
after that was run successfully you still need to install the rest
mkdir /hanamnt/shared/<SID>/hdbstudio_update
export TEMP=/usr/sap/<SID>/setup/logs_20130629132131
/i/51046016/DATA_UNITS/HDB_STUDIO_LINUX_X86_64/hdbinst -a studio    --copy_repository=/hanamnt/shared/<SID>/hdbstudio_update
/i/51046016/DATA_UNITS/HDB_STUDIO_LINUX_X86_64/hdbinst -a studio    --batch --path=/hanamnt/shared/<SID>/hdbstudio --vm=/usr/lib64/jvm/java-1_6_0-ibm-1.6.0/jre/bin/java
/i/51046016/DATA_UNITS/HDB_CLIENT_LINUX_X86_64/hdbinst -b -a client --path /hanamnt/shared/<SID>/hdbclient
rsync -avz --progress /i/51046016/DATA_UNITS/HANA_IM_LINUX__X86_64/LM_STRUCTURE_CONTENT/ /hanamnt/shared/<SID>/lm_structure/
cd /hanamnt/shared/<SID>/lm_structure
mv currentStack.template currentStack.properties
mv landscapeVariables.template landscapeVariables.properties
chown -R <sid>adm.sapsys /hanamnt/shared/<SID>/lm_structure
in currentStack.properties and landscapeVariables.properties replace all $(...) entries with your values
as <sid>adm you can now start yur database with: HDB start

Re: SAP hana-Attribute view creation->active version of the object does not exist

Re: SAP Mobile Application on standalone Hana or Hana Cloud

Hello,

You may find many sap hana usercase in the link http://www.saphana.com/community/implement

In general you can expose the data stored in SAP HANA using OData. Develop a mobile UI using SAP UI5 and call the exposed Odata service to display data.

I would recommend you to start POC using SAP HANA cloud providers recommended in the link http://scn.sap.com/docs/DOC-31722 (or)  http://www.saphana.com/docs/DOC-3581

Then based on your requiment you can migrate the application to your owwn SAP HANA system.

Rgds,

Mat.

Hi Srinu,

 

After you are done with the creation of Attribute view, first you have to "Save and Validate" the view.

If there are no errors, it will create the Inactive version of the object(attribute view).

 

For doing the data preview, the object has to be the active version of the object. So after  "Save and Validate" , you have to click on "Activate" (which is next to "Save and Validate") which converts inactive version of the object to Active version of the object. Also you can see a copy of your view in Schema _SYS_BIC  under Column View.

 

Now it will be ready to do the Data preview.

 

Regards

Raj

FusionIO vs. Hana?

Hi there,

 

i am not that HANA Specialist. Our BW System is running at the Moment on FusionIO. So my Supervisor comes to me and asked if we should not go to SAP HANA.

 

So when we want to use SAP HANA do we have to migrate the whole BW System to HANA? Or is it so that only Infocubes Methods and so on are only stored in the HANA System?

 

Can someone here explain the benefit FusionIO vs Hana?

 

Kind Regards

Re: FusionIO vs. Hana?

Hi Bjoern,

 

According to me :

So when we want to use SAP HANA do we have to migrate the whole BW System to HANA? Yes, you have to migrate whole BW system to HANA :

Or is it so that only Infocubes Methods and so on are only stored in the HANA System? No, Everything has to be migrated

You replace your existing Database with HANA.

After migration also you have to convert your DSOs to In Memory DSO and your Infocubes to INmemory Infocubes

 

Well if you are going to use HANA you are getting In Memory DSO and In Memory Infocube which have a slight structure change as "

You don't have Aggregates, Indexes, Dimensions( except for Package Dimension) and then there is only one fact table in In Memory Infocube

To learn more about IN Memory Infocube :

http://scn.sap.com/community/hana-in-memory/blog/2012/01/11/bw-on-hana-working-of-in-memory-info-cube


In IMDSO we don't have a physical Change Log table Instead we have a Calculation View and our Active Data Table acts as a "Temporal Table" .

Learn more about IMDSO :

http://scn.sap.com/people/thomas.zurek/blog/2011/06/24/hana-and-bw-730--part-2

 

As per my knowledge :

HANA is a In memory database - whole data is stored in RAM.

Fusion-IO is not a database - it is a in memory device which can be installed and configured in the database to use it for temp files, log files, and indexes to triple performance or we can also move whole database .

But Fusion-io needs a database like Oracle or MySQL to work on.


So HANA is a In Memory Database while Fusio-IO is used to accelerate database performance

There are many benefits to HANA as you get IMDSO, IN memory Infocube.

 

To learn more :http://www.fusionio.com/solutions/database/

Fusion-io  can be used with SAP HANA also :

Hi Bjoern,

Just to add to Vivek comprehensive reply you will need to ensure you run SAP HANA on certified hardware. You can get a list of the certified vendors and servers on the PAM.

FusionIO vs. Hana?

As already mentioned, you're comparing two different things.

You cannot compare HW x SW.

 

What Database is your BW system on today? Oracle? DB2?

That's what you gotta compare to HANA.

 

Also, most of the HANA certified HW uses FusionIO for the log files (read/write), while using SSD for the data files (read).

 

Best,

Henrique.

Thanks Subrahmanya

But my requirement is just to transform rows into columns while selecting data from HANA tables within HANA studio.

 

I checked that the PIVOT expression doesnt work in HANA as it would in SQL sever.

Is there any such expression or functinality avaialable within AN or CALC view?

Debraj

Hi Debraj,

 

There is no built-in function as such for PIVOT expression, but you can model the views using Calculated Columns i.e. Restricted columns or Calculated Columns using functions like IF construct.

 

Alternative is also to use a SELECT statement using CASE construct like mentioned here.

Hello Nilesh,

 

As Per SLT Guide we need to start the replication once Replication on below tables are successfully completed.

 

Table Names: DD02L, DD02T and DD08L

 

Because the above table having meta data of all tables in ERP side.

Like structure ,version ,Keys....etc.

 

Once replication on DD02L, DD02T and DD08L is completed.then Try the load the table.

and it will success.

Jagan
