HANA studio performance

We have HANA studio and can be log in via citrix or Direct log in to Program -HANA studio.
Citrix performance is better than direct log into HANA Studio.
Issue is:
Any view activating or changing taking 10 sec via citrix.
while the same view changing or activating taking 3 mins via direct log in.
Now we want to log in direct into Studio as it already installed. And Plan for removing Citrix log in.
Please suggest how to make HANA studio faster without using Citrix.
Regards,
kamruz

Thanks for your reply. We are connecting one network to other network. placing the HANA server is out of scope. We are using win 7 only.
How we can use jump box or VM. Please specify details.
We logged in via citrix or Direct log into Studio ( Start ->Application -> Studio)
Thanks,
Kamruz

Performance -- load tab in hana studio

Hi Folks,
I have a strange requirement here from hana studio.
I want to extract daily performance data from hana studio for the previous whole day/night and send across the graph as an email next day.
Now the problem is that i am doing it manually daily.
Is there a way to automate the same ?
nameserver_history.trc its very hard to intrepret the data from there. Is this possible ?

Martin,
Thanks a ton for the information,
What can we do with the current version, we cannot upgrade to SPS 9 at this moment. Any alternate work around?

HANA Studio rev.74 - performance in calc view with union of many sources

Hi,
Windows 7 32 bit, 4GB system memory, Intel Core Duo 2.26Ghz, HANA studio rev 74.
Maintaining a graphical calculation view where first node is union of 30 calculation views each with 150 columns. Maintenance of the view is terribly slow almost to the point of unusable as I add sources to the union, leading to a consideration of remodelling the requirement with a scripted view (or breaking down into smaller sets of graphical calculation views) to work around the sluggish response.
As well as building the view for development purposes I'm considering longer term maintenance options where I cannot guarantee system specs of the supporting developer.
Does anyone else have experience of such sluggish Studio performance with a graphical calculation view using many large view sources?
Is there any theoretical limit to the number of sources in a union?
Cheers,
JP.

Hi Jon-Paul,
sorry for going off topic, but...
if there's still an issue with the appliance (on CAL?), doesn't it flow over to the client? i have the client SP80 installed, but until i get the confirmation that the server i'm connecting to is 'production' ready i can't really take the full advantage of the upgraded client as i don't see any significant point of using client 80 with server 74, but it sounds like you would want to make it work, nevertheless.
to me, yellow is still yellow even though it doesn't really stand for anything.
good luck and let us know your test results,
greg

Unable to find custom table in HANA Studio - Data Provisioning - SLT

Hi All,
We are working on a scenario where in we have created a custom table in ECC and when I tried to find the custom table for performing replication using SLT , however, I am not able to find the custom table in SAP HANA Studio. The custom table related entries are maintained in DD08L, DD02L, DD02T. We are able to find standard tables in SAP HANA Studio which could be replicated using SLT.
Please could you let us know the reason or anything we are missing as pre-requisites for custom tables to be visible in SAP HANA Studio for SLT.

Hi,
Since you confirmed that the custom table details are available in DD02l, DD02T and DD08L,
I would request you to check the language in which the source table is maintained/created.
If the table at the source is maintained in a different language than you are logged in to HANA St
udio, it will not be displayed in SLT Provisioning.
Please let me know your observation.

Model in HANA Studio or IDT

Hello Everyone,
We have a question on a scenerio/approach:
1. We have HANA and have SLT table replication
2. Do we model in HANA (with Calculation Views, Analytic Views, Attribute Views) Studio or model the relationship model directly in Information Design Tool?
We see all HANA documentation states Calculation/Analytic/Attribute views and mentions only IDT for creating the Universe. We don't see anywhere that you should create the model itself in HANA Studio or IDT. Is there a preferred approach/Best Practice?
Thank You!

Not very sure, what was the scenario that led BI expert author to that conclusion. Hope it was not one of those manufacutred lab scenarios.
Based on my past couple of projects on HANA, I know this for a fact by default Analytic View runs faster than physical tables. Client have always come up with same question and we have performed tests to get the right results. You can do this simple test, run SQL statement on both and monitor "core" status on your HANA box. You can see in case of SQL, only 1 core get utilized and in case of Analytic Views all cores utilization will go up.
Also on article key concept it says "SAP HANA Studio is the primary client tool used to manage SAP HANA and to create analytic views" which is not true. "SAP HANA Studio is the primary client tool used to manage SAP HANA and to create DATA MODELS (which can be attribute view, analytic view, Calculation View)

Is data compression all automatic? Or does manual steps occur in HANA Studio

Hi all,
I'm new to HANA and have been leveraging SCN in a BIG way to answer my questions (thanks everyone for your contributions). This is my first post as I was unable to find an answer to my current question .
I've been reading up on data compression in HANA and I learned that there are different techniques, such as Dictionary, Cluster, and Run-length encoding.
My Question is: Is the compression automatic? Or does it need to be modeled within HANA Studio? Let's use Dictionary Encoding as an example. Are there algorithms in place within HANA that will automatically aggregate values so only distinct values remain? Will the attribute vector and inverted indexed tables automatically be created?
Just as some background, this is what I am basing my question on:
http://www.agilityworks.co.uk/our-blog/demystifying-the-column-store-%E2%80%93-viewing-column-store-statistics-in-sap-ha…
Thank you!
Kyle

Hi Justin,
you are right, the compression is related to the delta merge - and therefore, as long as delta merges happen automatically, compression will also happen automatically.
SAP HANA has two compression stages on the column store: the first - and typically dominating one - is the implicit compression obtained from using a data dictionary for all column-store columns.
The second stage is often called "sparse compression" - it offers additional compression on top of the dictionary compression, with several available algorithms. During the "optimize compression" run, the most appropriate compression algorithm is chosen for each column (and some columns may not be sparse-compressed at all, because it would not bring a benefit).
The optimize compression run does not happen with every delta merge. Instead, it will be performed with the first delta merge on a given table, and then only if the data content of the table has changed significantly (typically, if I remember correctly, the system waits until the number of records has doubled. Note that the optimize compression run may _change_ the compression type chosen for a given column. The sparse compression itself will be done with every delta merge, using the algorithms selected in the past optimze compression.
If you have switched off automatic delta merging globally, or if you have disabled automatic delta merging for a given table, there will also be no automatic compression (in the entire system or on the given table). BW on HANA uses the smart merge feature, so that in a standard BW on HANA, automatic compression will happen (with the timing of the delta merge being decided in a cooperation between BW and HANA).
Best,
Richard

30 days HANA trial: can I recreate VM for "SAP HANA Studio" in cloudshare?

Dear experts,
got the VM's for the 30 days trial both up and running.
Is it possible to recreate the VM's mentioned below to start from scratch again ?
a. SAP HANA SPS5 server
Installed: SAP HANA SPS5 server
OS: SUSE Enterprise 11 SP1 64 bit
OS: Linux
State: Running
b. SAP HANA Studio
Installed:
• SAP HANA studio
• SAP HANA client
• Office Professional Plus 2010 SP1
• Visio 2010 Premium Edition
OS: Windows 7 Pro x64 SP1
OS: Windows
State: Running

Thanks for reply,
As SLT is based on ABAP, so we can write complex logic in it.
But if we talk about SAP ECC standard data source, they have complex logic, based on multiple table.
So we need to write code from scratch in SLT to derive same result. but it will be huge time consuming , and required good ABAP skills, also it will lead to bug in code.
Also it will reduce the real time performance of SLT, due to complex logic.
Second option is procedure via SQL script, which is again huge effort in term if logic and can lead to error/bug in logic.
Does we have any other way or architecture to do this is very simple way, with high performance and less error issue.

If SAP could provide the HANA tools over just http:// instead of https:// then it would work under proxy conditions with the network connectivity option in eclipse set to "native" mode

HANA Studio: Filter more than one catalog schema

Hi,
Simply a usability question: Is it possible to filter a list of schemas in the catalog folder of HANA studio. I see only, that I can filter one pattern of a schema name. I would like to reduce the visible schemas in the catalog folder according to an arbitrary free to be chosen list of schemas.
Did I miss something?
Thanks,
Ingo

Hello Ingo Peter,
Very interesting question but I really doubt if it is possible!
Even giving 2nd Schema name will overwrite the earlier filtered Schema

Not able to start HLM from HANA studio

Hi Experts
I have installed SAP HANA SP07 version with patch level 4 on one of the node of a 4 node server.
4 nodes   A B C D
on node A i have installed AP HANA SP07 version with patch level 4    and everyting is working fine form HANA Studio 8.2
on node B i have installed AP HANA SP07 version with patch level 4    HLM is not working with HANA Studio 8.2 and at oslevel to.
i did update to latest HLM version ie., sp7 patch12.
but still the same error.
welcome any suggestions.
Thanks
Kishore

Hi Sadanand
Thanks for your update.
I did start the HLM as following
#cd /hana/shared/<SID>/HLM
# ./bootstrap-hlm.sh
i got the following prompt
<hostname>:/hana/shared/<SID>/HLM> ./bootstrap-hlm.sh
There is bootstrapped HLM
Checking for running HLM...
There is no running HLM.
Configure /usr/sap/hlm_bootstraps/<SID>/HLM/hlm.sh
osgi>
and now i can seel HLM process running at os level.
but still not able to launch HLM from HANA studio and the following URL is not working
1) via browser: http://<host>:1129/lmsl/HLM/<SID>/ui/?sid=<SID>

Unable to see SAP standard table in HANA Studio

Hello Experts,
I have requirement to built calculation view of SAP Standard Table like BSEG, BKPF table
but i am unable to view this table in Catalog view in HANA Studio.
Do i require any authorization or configuration to be done to view this table in those catalog view in hana studio.
Regards,
Mr. Dehey

Dehey,
Assuming that your SAP HANA is the primary database for your backend ERP instance (Suite on HANA), you need to have minimum SELECT privilege on the SAP<SID> schema, <SID> is the system identifier of your ERP instance.
Ask youur SAP HANA admin to grant the SELECT privilege on SAP<SID> schema to your user ID by executing the below SQL query from SQL console.
GRANT SELECT ON SCHEMA SAP<SID> TO <YOUR_USER_ID>;
Hope this helps.

Srinivas K.
