SLT with MDC

Hello experts,
Is SLT working with MDC?
If it is, how does SLT connect to the each tenant DB for data replication where there is one system DB?
Please advise.
Thanks.

Hi Tobias
Under MDC without scale out, there is only one hostname.
How do you distinguish the tenant DB from SLT perspective if SLT requires the hostname and instance number of HANA DB whereas there is only one System DB and one instance number in MDC?
Each tenant DB will not have instance number but port number. Below information is from the HANA administration guide.
The following is the syntax to create a tenant DB mentioned in the HANA administration guide. It does not have instance number but port number.
I think the lastest SWPM recognizes tenant DB with HANA DB info (SID, hostname, instance number) as well as the DB name of the tenant DB based on the information from the link below.
http://scn.sap.com/community/it-management/alm/software-logistics/blog/2015/01/08/hana-mdc-using-multiple-database-tenants-in-a-scale-out-scenario
I found out the following slide from one of the presentation documents about MDC.
Basically, there are two ways for applications to connect to tenant DB. One is using the SQL port number and the other one is to use the tenant DB name. If current SLT supports MDC with a single host, what should I enter in the LTR screen to connect to each tenant DB?
Please advise.

Object level authorization for SLT Configuration schema in HANA DB

Hi All,
We have connected SLT with HANA DB (& ECC as source system).
Now for certain users we wanted to restrict the access for certain tables ( tables owned by SLT Schema, i.e schema created in HANA DB with the configuration name provided in the SLT configuration).
With the SYSTEM user object level authorization's of another schema is not possible hence , an error is thrown when we are trying to provide/control the access of single table for a user.
Is it ok that we generate a password for SLT schema and try login with schema owner. Is it the best practice or Is there any other way around.
Regards,
Kumar

Hi Santosh,
You can find more info about SLT Roles and Authorization from below security guide.

SLT on sandbox Hana server 01- possible?

Guys,
Is it possible to test SLT or BODS on Hanasvr-01 ( provided as sandbox access by SAP)? If so, can you please let me know how to use it ?
If not, can you point me to some documentation of using SLT/BODS 4.0.
Thanks

Hi HANA_FOLLOWER,
At the Moment, neither SLT nor Data Services are configured in the Developer Center HANA systems. We have mentioned it several times, and I repeat it again: we can add replication to our sandbox systems if the community demands it. So reply to this thread if you are interested in trying SLT or DS - if enough users want it, we'll add it. How many are "enough"? Hard to say, but I would hope for at least 5% of active users. As of now, this would mean about 25-30 votes...
Regarding documentation: the [SLT installation guide|https://websmp209.sap-ag.de/~sapidb/011000358700000604912011] on [http://help.sap.com/hana] contains some information on how to use SLT with HANA in chapter 5. And for data services, just use the normal DS documentation, e.g. the [DS admin guide|http://help.sap.com/businessobject/product_guides/boexir4/en/xi4_ds_admin_en.pdf] - for DS users, HANA is just another ODBC data source.

Not able to get performance gain using Multidimensional Clustering

Hi All,
We are trying to test the effect of Multidimensional Clustering on the
performance of queries, infocubes/DSO loading and deletion of requests
from BW objects.
Unfortunately we are not able to see any performance gain when we use
MDC.
We are using following steps to test MDC:
1> We have created copy infocube ZPOS10_CP from original infocube
ZPOS10_V5.
2>In the new infocube ZPOS10_CP, we switched on the MDC Settings.
3> We are using following dimensions as MDC Dimensions:
       1> SID_0CALMONTH Calendar Year/Month
       2> Dimension ZPOS10_CP5 (This dimension is based on Site, Dist.
Channel etc).
Dimensions were selected based on consideration that:
       We should use those dimensions which are often used in query
Restriction.
When we are trying to load the same file in both original infocube with
NO MDC and new infocube with MDC there does not seem to be any major
improvement. Both of these loads are taking almost same time.
Can you please tell us how can we effectively use MDC? Is there any
setting that we need to do regarding extent size of tablespace etc?
Kindly help us to resolve this issue.
Regards,
Nilima Rodrigues

Hi,
In MDC we are not creating any dimensions.
Basically we just select some dimensions of Infocube as MDC Dimensions.
based on the suggestions provided by SAP on MDC, we have selected 0CALMONTH as one of the MDC Dimensions.
Other dimensions are chosen on the following recommendation provided by SAP:
●      Select dimensions for which you often use restrictions in queries.
●      Select dimensions with a low cardinality.

Nilima Rodrigues

Finder ignoring OD permissions

Hi all,
I am having weird permissions anomalies where the Finder reports one thing but allows another.  This is limited to our xSan volume, which has been rebuilt twice but the problem remains.
If we take a folder, called 'boris' for example, and set its permissions in WGM to;
Owner - Diradmin R&W
Group - project R&W
Everyone - NA
A user who is a member of the 'project' group should have full R&W to the folder 'boris', and in the finder you can open the folder and write files to within.  However if you try to set this folder as a FCP scratch disk, you are informed that this folder is write protected, as FCP checks the POSIX permissions when setting scratch disks.  'Get Info' confirms that "You Have - No Access" even though it reports the correct owner and group permissions.  Yet as mentioned previously I could copy a file into it or rename something within the Finder as if I had full R&W.
The only way to get it to work is to either set the ownership of the folder to the user, or set 'Everyone - R&W', neither of which is ideal.  The really strange thing is that sometimes it is a problem, sometimes not.  I could create 2 new folders (each with thier own group) at the same time, one might work the other might not!
So far I have tried:
• Rebuilding xsan volume
• Upgrading OS version
• Rebinding clients
• Rebuilding clients
• Rebuilding users / groups / folders
• Problems is constant accross intel and PPC clients
• Promoted the ODM to a MDC (temporarily as a test) to test if there was a problem with MDC binding.
Any ideas?

Users are using OD network accounts/portable accounts (to get unique "local" UIDs) - it's automatic when "bound"?
All users are from OD, no local users.
"FCP checks the POSIX permissions when setting scratch disks"
I guess this is correct (it's a "local volume" to all Xsan participating computers). The "use ACLs" on the Xsan volume when setting it up - could it matter here?
No ACLs activated on volume.
When sharing a volume over a network (AFP/SMB) you either use the default "use ACL's on this volume" or use the "Panther" "inherit permissions".
(Thinking aloud here: The WGM is used to set "local" permissions for Xsan participants on the Xsan volume. The OD user/group membership and the OD master is involved how? The metadata controller and the OD master should be running on different machines: which computer/service is allowing access to files/folders?)
Metadata controller bound to the ODM. So during a read/write to the xsan the cleint sends the request to the MDC along with the UID, as the MDC is bound it is aware of the permissions structure.

No more Xserve RAID

Apple is no longer selling the Xserve RAID.
They are supplying hard drives for existing devices as long as supplies last.
The new RAID by Promise is NOT compatible with XSAN 1 any version, nor is it compatible with FCP Studio 1
This is all per an Apple engineer about 20 minutes ago.

Not compatible means the Promise RAID ONLY runs with MDC's running XSAN 2 and Leopard OS.
XSAN 2 is backwards compatible with XSAN 1.4
So basically what you have to do it make sure your MDC's are at Leopard and XSAN 2 then put the Promise RAID in as a new volume instead of adding it to your existing volume. According to the two engineers I spoke with, you can technically add it to your current volume, pending all the versions are correct. I personally would never do that just because of the different LUN sizes between the two RAIDS.
Since XSAN 2 is supposed to be backwards compatible with XSAN 1.4 theoretically you could leave your clients at 1.4 but they wouldn't have access to the new volume since it requires XSAN 2.
Let the bugs begin.

Some confusion in MDM

Hi,
I am new to MDM. I have some confusion with MDM:
1. After "Loading Master data" process data from MDC will be copy (except replicate) to MDS (Staging) or it just some logical links that will be stored in MDS towards MDC.
2. Before "Consolidating Master Data" process do we need to define some database schema over MDS or it is an automated process.
3. Apart from consolidation and harmonization within heterogeneous system landscape is there any other benefit associated with MDM 3.0?
4. Does MDM 3.0 shipment comes with MDC adaptor to connect with SAP (ERP and CRM) system and Non-SAP system (like people soft). To my understanding it does have adaptors for SAP but not for non-SAP system.
5. Help.sap.com say during initial load from trusted clients (ILTC) process ID mapping information can be loaded directly from the MDC and transferred to the CI. But how can we store ID mapping directly in MDC?
6. Do we need to have all these component in order to use MDM:
   a. Master Data Engine 3.0
   b. Content Integrator 3.0
   c. BI (BW 3.5)
   d. EP 6.0
   e. XI 3.0
   f.SAP Solution Manger 3.1
Thanks
Raj

Hello Raj,
answers foryour questions :
1. After "Loading Master data" process data from MDC will be copy (except replicate) to MDS (Staging) or it just some logical links that will be stored in MDS towards MDC.
A: The data will be copied, there are no logical links. After the extraction the data exist on the Client-system and in the staging area.
2. Before "Consolidating Master Data" process do we need to define some database schema over MDS or it is an automated process.
A: We have to consider different cases:
Case 1) Extraction of Standard object types like Business Partner: It's not necessary to define some Database schemas, for the MDM standard object types, they already exist.
Case 2) Extraction of Standard object types, but enhanced by additional fields, e.g BP has some extensions: These extensions need to be defined also on the MDM server, and a regeneration of the Staging are might be necessary. There are tools available to do this.
Case 3) If you would like to extract your own defined Object types, the object type needs to be defined on the MDM Server (with the Master Data Framework).
3. Apart from consolidation and harmonization within heterogeneous system landscape is there any other benefit associated with MDM 3.0?
A: To mention just a few: You keep your data in sync also in the future, Global Spend analysis can be done across systems, one stop Data Maintenance.
4. Does MDM 3.0 shipment comes with MDC adaptor to connect with SAP (ERP and CRM) system and Non-SAP system (like people soft). To my understanding it does have adaptors for SAP but not for non-SAP system.
A: For the available adapters please look in the MDM Master Guide. Adapters for third party systems are/can be provided by our partner community.
5. Help.sap.com say during initial load from trusted clients (ILTC) process ID mapping information can be loaded directly from the MDC and transferred to the CI. But how can we store ID mapping directly in MDC?
A: The ID mapping is not stored in the MDC, it's stored in the CI. The data is only extracted from the MDC's. Regarding key-mapping from an MDC perspective, there are no changes compared to the normal load.
6. Do we need to have all these component in order to use MDM:
a. Master Data Engine 3.0
b. Content Integrator 3.0
c. BI (BW 3.5)
d. EP 6.0
e. XI 3.0
f. SAP Solution Manger 3.1
You're right, with the exception of the SAP Solution Manager. Solution Manager is higly recommended in an MDM installation, but you can run MDM also without. Without e.g. customizing ID mapping would need to be done manually, which can be a major effort.

Can the Sony SLT a77 be thethered with Lightroom 5.3?

Refer http://helpx.adobe.com/lightroom/kb/tethered-camera-support-lightroom-4.html
If your camera is not listed (only select Canon, Nikon and some Leicas are listed) then tethering is not supported in Lightroom.

Leopard MDC with Tiger Clients?

I'm well aware of the rule which states MDCs should be the same as, or no more than one version ahead of, the cleints.
So far so good.
Does this mean I can update the MDCs to 10.5.1 server whilst leaving clients on 10.4.11 for the time being?
Trying to update the entire system in one go will spoil my Christmas!

It is possible, if you're using the latest version (1.4.2). Won't work with an earlier version.
Read the release notes for 1.4.2 -- it has specific instructions on exactly what configs are supported and how to upgrade to it.

SLT not working properly with Non-SAP source

Dear All,
We have MSSQL 2005 as a source. We are doing SLT to load data in HANA.
The issue here is:
MSSQL has an integer field whose default value is set to NULL. However, after doing SLT, data in HANA default data comes as Zeros instead of NULLS.
The issue is with columns with integer datatypes only.
Please help.

Replicate an oracle view with SLT

Hi -
Using Oracle 11g and SLT 2011_1_731 Patch 7 with Hana rev 82
I am trying to replicate oracle views in hana through SLT
Scenario 1:
tables T2 and T3 with View T2_T3_view
If I follow this thread SLT view replication
It creates the view as a table in hana but does not populate it with any data.
Scenario 2 -
I have 2 oracle tables - T4 and T5. I have a view T4_T5_VIEW that joins the 2 tables.
I followed steps in a document I received to replicate the view syntax as well as the tables.
1) replicated both tables T4 and T5 - success
2) stopped replication on T4
table exists in hana with data but no replication
3) using LTRS, assigned the view T4_T5_VIEW to table T4
4) changed the performance option
5) restarted replication on T4
The view gets created as a table, but table T4 gets and error and does not replicate.
The view gets no data
What is the proper process for an oracle table?
I have a very complex view with 5 source tables I want to replicate.
Thanks
Diane

Multiple Schema Creation with One Source system Via SLT

Hi all,
we have BW on HANA environment at our company premises, with SLT server installed
So, my Question is that is it possible to create more than one schema in HANA system with one Source system
As an example, lets say, ECC (Client 601) Source System has been connected to HANA via SLT and created Schema called SCHEMA_1 and again i want to create SCHEMA_2 by connecting same ECC (Client 601) source System.
please help me to short this out?
Thanks
Mirana

Hi Mirana,
Yes, it is possible to create more than one schema in HANA system with one Source system.
