Hi David
That looks like quite an old version of Studio, if you can't update it I'd suggest trying a fresh installation of the newer Studio version, you can have multiple Studio versions installed.

Resident memory and used memory large gap
Hi Team,
When we check from studio, resident memory vs used memory gap is very high.
Is there a way to do some flush or garbage cleanup and bring down the usage.
Hana version is :
HDB version info:
version: 1.00.82.00.394270
Will put in some more information.

Re: Resident memory and used memory large gap
Could you please describe why exactly you want to do that? It's normal to have used memory below resident memory.

Hi,
Just to backup what Liz said, here's an SAP KBA describing your scenario:
2081473 - High Memory Useage: Resident Memory

Re: Resident memory and used memory large gap
Hi Lucas,
I think this topic has been raised several times earlier.
Like in the below thread.
https://scn.sap.com/thread/3424524
As you are aware OS tools will monitor from a operating system perspective which would be the resident memory. There is no mechanism as such to reduce the resident memory usage like the high water mark in DB6 
.
System is would be monitored by the DBA team and the operating system administrators team. They wouldnt understand that the used memory is low but the resident memory is high.
So is there a mechanism to reduce the resident memory usage or bring down especially in cases when there is a large gap.

Re: Resident memory and used memory large gap
Hi Liz,
Thanks for your response.
I am aware of the large gap between used memory and resident memory but the difference cannot be ten folds.
When the used memory is 200 GB and resident memory is around 1900GB. I am not saying its a problem but i am saying is that from operating system wise its still very high usage.
SAP might have given the flexibility to lower the resident memory usage especially when the difference is very high.

Re: Resident memory and used memory large gap
Hello,
Yes you're right. It has been asked before. SAP has a Note about it and the administration guide has info regarding it as mentioned in thread you found. So, what's missing?

Re: Resident memory and used memory large gap
I don't think you should worry about the gap though - it's not the problem, it simply means you have a lot of memory that can be used later.
The big gap only means that at some point you had really high usage going on. So I would concentrate on identifying WHAT caused the gap rather then how to shrink it.

Re: Resident memory and used memory large gap
Hi Lucas,
As i said earlier, want to bring it down. Something like we have HWM high water mark in DB6 is it possible?
So would like to know to more from you about the same.

Re: Resident memory and used memory large gap
Hi Liz,
Good Day!
If you check my response. HANA DB OS would be monitored by OS tools. We would be getting uncessary alerts. So dynamically reducing the resident memory would help a lot.
What caused the gap is definitely important but right now the priority is to get the resident memory shrink and give back atleast some part of memory back.

Re: Resident memory and used memory large gap
A little bit off subject, but a question popped up into my head:
So memory manager requests more memory from OS if there is no more memory in HANA pool. This will continue until a "predefined allocation limit" (I guess the global_allocation_limit). So, I just wonder, what would happen if our resident memory is let's say 200 GB, and we lower the allocation limit to 150 GB - what would the monitors show? (yeap, we can bring the allocation limit back to what it was right after as it's dynamically switchable).

HI Nitesh,
Have you done the Static server migration ?
what is the backup that you used ? is it the same version ?

Re: Calculation view slow when quering only dimension
Hi Rasmus,
I'm not an WebI expert, but I remind in a project some years ago that is possible create personalyzed LOV's and customize the exposition of the query. Is it not possible?
Another thing is that at that stage wasn't possible to directly select on HANA without model it first on Universe, so maybe time passed and now there are some things automatic and you can access directly a calculation view without model it on universe, but anyhow even in cases like this can't you personalyze an LOV acessing the dimmension directly?

Re: Aggregation of Key figures with Null value for the attribute
Hi Prem,
On the Union node go to the column_name on the right box, right click on column_name and choose Manage.
Adjust the settings so you can put an default value instead null.

Re: what is the role of "Any" in configure external SAML Identities
Hi Tatab355 Tatab355 ( I prefer talk to people ),
I took a time to google, as I don't know the answer, and find something that can answer about the ANY on create user statement CREATE USER - SAP HANA SQL and System Views Reference - SAP Library
Defines a SAML provider.
<mapped_user_name> ::= ANY | <string_literal>The mapped SAML user name to use. If the keyword ANY is used the SAML assertion will contain the name of the database user that the assertion is valid for.
It's just a guess ok. I had no oportunity to stablish such authentications before.

Re: Aggregation of Key figures with Null value for the attribute
I was looking for a picture of Manage Mappings to send to you, you can see on this sample of UCV Effective Query pruning using Constant Column in UNION node
During this I found an old discussion that I guess is important to you read Union with Constant Values
UCV are in line of what you need to implement more than the null values that you found.

Re: HANA Modeling Guide for SAP HANA Studio vs HANA Web Workbench
Hi Lucas,
Appreciate your response. The main reason I posted the question was to find the difference between the two pdfs provided by SAP (that is the title of the discussion). I do not see any related existing discussion.

Re: HANA Modeling Guide for SAP HANA Studio vs HANA Web Workbench
Hi Sunitha,
This sort of question has been asked over and over again here in SCN. Please search before posting question. A very naive search here brought me *lots* of results :
http://scn.sap.com/search.jspa?peopleEnabled=true&q=start+learn+hana&Submit=Search
** EDIT **
Regarding the difference between WebIDE and Studio modeling guides: it is basically the same concept on different front-ends. As of now Studio has more flexibility than WebIDE. For instance you can't create attribute views on WebIDE while Studio allows you to use the whole modeling features stack. This will surely change over time and Web IDE will become more and more powerful.
