MDM Slow

Hi All,
I have approx 8 lakhs rec in my MDM rep.
I am just an end user of MDM ,woh login to the Data manger to perform Data validations.
However as the number of records in MDM increases day by day i observe that it is taking a lot of time to perfrom even small activities in DM.
To an extent that even opening the DM or switicking between tabs is taking very long.
Plz Guide me to improve this.
Thanks
AJ

Hi Amruta,
Performane of MDM depends on many parameters like
1. Hardware configuration of the system where MDS is installed
System should be configured as per the sizing guide i.e. CPU, Hardisk and RAM required for successful MDM operations
2. Network speed between the machines where MDS and GUI Clients are installed
3. Change Tracking
Change Tracking should not be enabled for all the tables and for all the fields since everychange is written in database which unnecessary increase CPU time and database size
4. Data Modelling like Keyword, Sort Index
Keyword should not be enabled for all the fields or specifically for the fields having unique values since MDM load all the field values for which keyword is enabled at the time of loading which occupies lots of memory space.

Unable to connect to MaxDB database

Hi Experts,
I have installed SAP MaxDB database(version 7.7.06.09) based on the MDM7.1 Installation Guide.
I am trying to connect to MaxDB database to create repository in MDM console.
at this movement, I am getting error like "unable to connect to database"
Please guide me if anyone have idea related to this.
Thanks,
RDNPrasad

Hi Jitesh,
I have checked the server log file, I found the error is mentioned below:
Error: Service 'Host name', User 'SAPMDMDB', Schema 'SAPMDMDB' Connect failed
ERROR CODE=-10709, Connection failed (RTE:[5] database not running)
I have checked in the services the MAXDB:MDM and MAXDB: .UMDB are running and these are set to Startup type property as "Automatic".
besides i found other services related to MaxDB(MAXDB: MDM(slow), MAXDB: .M770401, MAXDB: .M770401 (slow) , MAXDB: .M770428) are not running and these are set to startup type property as "Manual"
Please let me know if you have idea about this.

MDM with Lion Server is too Slow

Managing 500 iPads with an iMac Mini Server is a very time Consulting Job, because MDM is too Slow. The reason seems to be postgres database. Any Suggestionen?

There really isn't enough information here to solve your problem.
Fair enough, we get it's slow... but when you say "click the Finder icon it spends 10-20 seconds to open", are you talking about on the server itself? or over the network?
In addition, what do the server logs have to say?
What about activity monitor? What processes are busy? What about memory utilization?
There are all kinds of things that can contribute. Far too many to be able to pinpoint from the (lack of) information available.
All I can say is that reformatting/reinstalling is not likely to be your best option.

MDM Server is responding very slow

Hi,
I am working with only 21,695 records and MDM Server is responding very slow.
MDM Server is running on Intel(R)Xeon(TM) 2.40Ghz 2.39Ghz, 3.89 GB of RAM.
System: Microsoft Windows Server 2003 Standard Edition Service Pack 2.
The hard disk partition F: has 43.7 GB Freespace.
It is impossible to do MDM Workflow matching and Merging with this slow speed.

ABAP MDM Connection Pool concept? Slow Performance in call

Hi,
I'm playing around with the MDM ABAP API, and I found the performance a bit disappointing.
I followed the guide "How To identify master data records using SAP MDM 5.5 ABAP API's" and wrote a test program.
The program makes a connection, triggers an MDM query, and disconnects.
    CREATE OBJECT api
      EXPORTING
        iv_log_object_name = logical_object_name.
    api->mo_accessor->connect( language ).
* Query parameters
    ls_query-parameter_code = 'Material_Number'.
    ls_query-operator = 'CS'.
    ls_query-dimension_type = 1.
    ls_query-constraint_type = 8.
    ls_value = '70'.
    GET REFERENCE OF ls_value INTO ls_query-value_low.
    APPEND ls_query TO lt_query.
    CLEAR ls_query.
* Search
    CALL METHOD api->mo_core_service->query
      EXPORTING
        iv_object_type_code = 'Products'
        it_query            = lt_query
        iv_hits_max         = 10
      IMPORTING
        et_result_set       = lt_result_set.
Connection is really fast (a split second)
First time triggered 'query' method took about 30-50 seconds.
Second time triggering 'query' method took a split second.
Further to my investigation, I found out the most expensive code lies in
CL_MDM_PROVIDER_SP04_PL03->IF_MDM_CORE_SERVICES~QUERY
*--- load field meta data ---*
IF mt_mdm_field_meta_data IS INITIAL
OR mt_field_meta_data     IS INITIAL.
    CALL METHOD me->_load_field_information.
ENDIF.
Within this method loadfield_information, it rips all the table and structure information
from MDM, and ALL language texts and so on.
It has many loops, and within the loops querying MDM for more information.
Is there anyway to speed this up?
Why aren't these data cached? (They don't change so often in a production environment)
I also found a shared memory class CL_MDM_METADATA_ACCESS but it is not used anywhere.
No shared memory area relevant is delivered by SAP as well.
Any ideas?
Cheers,
Michael.

Hi Michael,
you're welcome.
I'm not sure how the Connection Pooling to MDM is really done by the ABAP APIs as I'm unfortunately not an API developer but just use the API for my programms.
What I learned during this process is that the repository meta data (meaning table descriptions, and so on) have to be loaded at least once for each connection. This makes sense because a repository can always be changed manually by any user. And I don't think that it would be faster to hold the meta data persistent in the ABAP layer because then you would need to compare the ABAP available meta information with the current meta information of the repository. This could take even longer.
I've solved this "issue" in a way that I really rely on the connection because a single connection is very stable. So I call the "CONNECT" only once in the very beginning, run through my coding and the very last step is the "DISCONNECT". As long as a connection is available, the meta data is cached in the API layer (at least this is the case for SP05).
BR Michael

Slow performance of Day 1 Sync batches in CC&B and MDM

Im running a data conversion team on a project that is integrating CC&B 2.3.1 (currently running SP3 and Framework13) and MDM 2.0 (currently running SP4)
We are using the Day 1 Sync batches to replicate data mastered in CC&B for Service Points, Contacts and Service Agreements/Usage Subscriptions into MDM.
While running the Initial Sync batches for Service Point, Contact and SA/US to MDM, the time taken taken is very long. We have tried to run the batches in both single and multiple threads ranging upto 8 threads but the performance was not improved with more threads.
While running the Initial SYnc Service Point batch from CC&B, with 8 threads and 48,060 records it took 11 hours and 41 minutes which is equivalent to just over 1 record processed per second. The overall batch run time in MDM was close to 7 hours.
While running the Initial Sync bactches for SA/US in MDM, it took a total of 31 hours to process close to 60,000 records.
This is a big concern from a Migration perspective as the volumes of data would be much more than 48,000 records. And considering 48,000 records took around 12 hours, we're concerned regarding the overall timings for all the Sync batches.
Below are the timings taken to execute the various batches for Initial Sync in MDM:
Service Point Sync (48,060 records)
F1-SYSRQ (Sync Request Sampling Monitor Batch): 2 hrs 30 minutes
F1-SAKRQ (Sync Request- Allocate keys monitor): 43 minutes
D1-SIKSP (Initial Sync Request- Resolve keys SP): 1 hr 47 minutes
D1-SILSP (Initial Sync Request- Load Data SP): 2 hours 12 minutes
Usage Subscription Sync for 60,000 records:
F1-SYSRQ (Sync Request Sampling Monitor Batch): 4 hrs 34 minutes
D1-SIIER (Initial Sync Request Error): 7 hrs 18 minutes
F1-SAKRQ (Sync Request- Allocate keys monitor): 46 minutes
D2-SIKUS (Initial Sync Request- Resolve keys US): 18 hrs
D2-SILUS (Initial Sync Request- Load Data US): 1 hr 28 minutes
Please note that we're running on Service Pack 4 for MDM.
Technical Specification of the environment that these batches are running on:
CC&B:
Online/Batch Server (Number of Servers * RAM * CPU) 2 * 4GB * 2CPU
OS AIX 6.1 TL7
JDK JDK v5.0 SR10 64-bit
Weblogic Version 10.0 MP2
Batch threads <= 8
JVM Count 2
MDM:
Online/Batch Server (Number of Servers * RAM * CPU) 2 *4GB * 2CPU
OS AIX 6.1 TL7
JDK JDK v6.0 SR8 64-bit
Weblogic Version 10.3.3
Batch threads <= 8
JVM Count 2
Has anyone seen issues with performance of these batches previously? When running the number of records processed by CC&B and received by MDM are in alignment so there is no issue in teh Fusion Middleware. It just seems that the processing speed of CC&B and MDM is poor.

Hi Amaresh - thanks for your response.
We are running batch online in our conversaion test environment. For the final Prodcution environmnet we'll be using third party software - CTRL-M.
We seem to be getting some additional speed now by running the batch with multiple threads but I'm still not convinced that this is going to be enough.

Device management - Profile Manager - MDM

Device management with mac os x lion server:
I saw that with profile manager (an apple implantation of its mobiledevice management apis) allow you to enroll and manage iOS devices. I want to know if this OS with profile manager MDM can work for managing 20 ipads with MAC MINI. What hardware do you recommend to buy? MAC MINI or MAC PRO? I think mac pro will be better but I need to reduce costs so I choose MAC MINI but I want to know if it will work fine to manage our 20/22 ipads.
any advice about mac mini for managing 20/22 ipads? docuemntation/info about this?
Thank you very much
Regards,

We manage 500 iPads. But mdm is quite slow. When you start, you wait up to 5 minutes until devicemanager is online.

MDM Solution Advice

I'm not sure if this is the best category to write this post in, but I didn't see anything better. Long story short I'm looking for an MDM solution. Currently I'm looking at AirWatch and Casper and would like to hear from other IT admins what they're experiences have been with each.
If you're following me so far, you'll probably want some environmental information. Here's the scenario, I work for a hospital that not only deals with technology inside the hospital, but also works in conjunction with 15 remote clinics. Normally that wouldn't be so bad, expect to reach any of these clinics you have to fly by plane. We have to minimize bandwidth usage as much as possible, internet speed is slow, and connections can be intermittent at times. Luckily each clinic is on a central network that's accessible from the main hospital, and allows us to remote into the computers currently installed at those locations.
Not exactly you're typical MDM scenario at a university or school. I need some advice and real world feed back from anyone who's used either AirWatch or Casper. Personally I'm leaning towards Casper, but my boss whats the multiplatform capabilities of AirWatch in case we begin to deploy non Apple mobile devices.
Thanks,

MDM Material Data and BI

I have a customer that will be sending material data from MDM to BI. In BI, they will be doing reporting using certain navigational attributes we've developed. From our experience, the process of using the navigational attributes seems slow as you step through and give each one a criteria.
Does it makes sense to do the lookup in MDM and send a list of material numbers to BI. I am thinking that might be faster but, he have no idea how this could be accomplished technically. Do you have any thoughts on using MDM to perform a quick search to get a list of materials and then sending the list to BI as the source for the reports.
Thanks
Paul

In case of MDM and BI integration, there are several ways to perform the same.
1. Using File transfer system - As you have mentioned that in BI we define navigational attributes and transfer the Master data in the form of a .CSV file to BI, which then can report on both the Local Id's and the Global Id's.We had done this scenario with MDM SP04 and the reporting seemed to be good at that time.
2. With higher versions of MDM, there is a direct integration of MDM with BI using ABAP APi's. INfact the repository was created from BI in MDM server and only Data Manager is used in that case. You can go for this method as well. Plese find the link below to understand the same.

http://help.sap.com/saphelp_nw70/helpdata/en/45/5d3bfaa9ef3bdfe10000000a1553f7/frameset.htm
3. Now coming to your requirement, if you want to use searches in MDM, then you can definitely do that in MDM. The records which get selected in the search creteria can be then syndicated to BI using the File transfer mechanism. This might increase up the speed as only few records will be syndicated as per the search creteria set. You can set the search in Syndicator directly.
Hope this info helps.

Main table vs Look up Table in MDM 7.1

Hi All,
I was looking at major differences between Main table and flat table.My question is what stops me from using my lookuptable as the main table as I can do Syndication,key mapping etc even with my flat tables.(Unless I am wrong in my assumption).
Regards,
Premjit

Hi ,
Maintable will hold data for a particular maste. It contains primary information about a business object such as a product or supplier. Lookup table will be a field which describes the master. you cannot use lookup as a main table because:
1. The data model flexibility to accomodate different data types: such as hiererchies, taxonomies, QT wont be possible using flat lookup tables.
2. Storing such a huge amount of data(lacs of records) in lookup will have lots of performance related issues and will slow down your MDM instance.
3. During integration with Portal it'll be very difficult and will require huge effort to use MDM JAVA API's to fetch/enter data to MDM.
These are few reasons which makes the case of using lookups as MT very weak. There will be more reasons im sure.

Purging Completed WorkFlows in MDM

Weu2019re running SAP MDM 5.5 SP 6.
We implemented the SAP Note Number: 1240587 about 1 ½ years ago. Here is the linku2026
http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_mdm/~form/handler%7b5f4150503d3030323030363832353030303030303031393732265f4556454e543d444953504c4159265f4e4e554d3d31323430353837%7d
It really seemed to help initially. We went from 3 hours to load the repository down to 1 hour. Yahoo!
Unfortunately, we are seeing it slow down again (2 ½ hours). After some research, we discovered that the Java Utility will ONLY delete the Workflows that are assigned to the ID that is running the Java Utility. Example: Admin ID will only delete the Workflows that were launched by the Admin ID, such as Syndication and Import Managers Workflows.
We have several hundred people that can initiate a workflow to request a part change or add a new part. So, running this job under their IDs is not an option.
1) Is there some way to create a Supper User ID that will delete all the Completed Workflows and not just the ones for the ID that is running the job? If so, how do you create this ID, since we currently donu2019t have an id like that?
2) Is there some way we can change this job to loop through individual IDs to delete the completed Workflows?
3) Or did someone get the Database Trigger to work that I read in a few discussions?
4) Any other suggestions?
Your help is greatly appreciated!!!

Dear Henry,
First, let me tell you the concept:
It is Workflow Owner which has a special privilege to delete the Workflow Job at any point of time. The moment any user triggers a Workflow Job, Owner can see the status at any point of time and can take the control from any other user id.
There are two options to define or declare a Workflow Owner:
a) Any Specific User ID like in your case it is Admin. or
b) The launcher who initiates the Workflow Job.
Now your questions:
1) Is there some way to create a Supper User ID that will delete all the Completed Workflows and not just the ones for the ID that is running the job? If so, how do you create this ID, since we currently donu2019t have an id like that?
Ans: It is just like any other user id which are created in MDM Console. Yes you make a user id through Console and assign Admin Role to it. Now put this user id in Workflow Owner property and then you can execute your Java Utility to establish a session of this user id and delete all completed Workflow Jobs. It would not make any difference as this id will be like Admin.
2) Is there some way we can change this job to loop through individual IDs to delete the completed Workflows?
Ans: In this case you need to make Workflow Owner as Launcher and now whoever will trigger Workflow Job, that will become the Workflow Owner. Now you need to retrieve all user ids from MDM Console and establish a user session using Java utility, then you can delete all completed jobs which were assigned to an individual user ids. You need to customize your java utility here.
3) Or did someone get the Database Trigger to work that I read in a few discussions?
Ans: Better to use Java Utility instead of Database commands and schedule java program in background.
4) Any other suggestions?
Ans: Nothing :).

Import large batches of WMA slow... Smaller batches, faster. What gives?

If I try to import more than like 20-30 unprotected WMAs into iTunes, the conversion is god awful slow. If I do them in smaller batches, it flies.
What's the deal? Bug in iTunes?

Hi VijayaKumar.
Import Server(MDIS) is best for importing Mass or Bulk Data. Please verify this on Page 246/403 of MDM Console Reference Guide. Table 63. Conceptual Differences Between Import Manager and MDIS
http://help.sap.com/saphelp_nwmdm71/helpdata/en/4b/71608566ae3260e10000000a42189b/MDMConsole71.pdf
Maximum import file size Limited (50,000 records) for IM Unlimited for MDIS
I think you need to make use of Import sleep time and Import Slice Size parameters for MDM Optimized Performance.
How to configure these Parameters for this Please refer below thread:
how to configure import slice and import sleep time in MDIS ?
Also please refer, Table 59. Optional MDM Server Parameters of MDM Console Reference Guide:
parameters like: Bulk Import Silo Page 226-227/403
Hope it helps..

MDM Server - Portal System Settings

Hi ,
Can anyone send a link to a good document on MDM Server and Portal system settings.
Best Regards
Sid

Hi Kunal,
Portal is just the Front end for the backend system MDM.
So if the performance in MDM is slow the same will be reflected even on the front end system.
To improve your MDM system you need to set the field properties in MDM correctly .
Basically your data modelling in MDM must be correct.
Kindly Follow the belwo links which will guide you in improving your system performance by efficient use of data modelling techniques:

Future of SAP MDM

Hi Experts
I would like to know the future of SAP MDM module ,will it be safe for anyone to continue with the MDM module,or is it going to be phased out by other SAP applications.Can anyone throw light on this?
With Regards
Manoj

Hi Manoj,
If you look at the current market situation.Not just SAP-MDM but also other technolgies are facing the challenge to survive.
The market is going through a lot of instabilty and downtime and not many customer are willing to take risks with their money and work.
The only difference that stands between SAPMDM and others is that MDM is now in its initial stages.It still has to mature as afull fledge solution for customers.
and with the MDM 7.1 release it has taking a good kick start and is still improvising and developing iwth every hotfix and patch.
But reatining the fact the Customers are still very unsure of MDM's results they are not ready to take that easy plunge at this point of time which is making MDM are slow runner.
But if you look closely with what MDM can deliver with the latest MDM 7.1 version and the business problems the companys are facing with their master data especially in a time of mergers and acquistions.SAP MDM will rise as Precise effective and unavoidable solution for customers.
So in my prespective the future of MDM is bright in the long run.
Hope It Helped

MDM performance test

Hi all,
Anyone has done a performance test on MDM? Any test script would be really helpful!
Thanks in advance.

Hi,
MDM Performance need to be monitored in basically two main MDM activities when it come to working in MDM real time:
1) MDM Importing
2) MDM Syndicatiion
MDM Importing:
- When ever you are using MDM in an IT Landscape there will be many source systems from where data will be inputted into MDM.
- This data may either be imported in a Manual fashion or Automatically as in most case using the MDM import server.
- In either case you will have to deal with thousands of records.
- Importing such a large set of records afftects the performance as very stage till importing means(at the record matching steps etc till teh final import)
- The performance gets affected slowing the process of importing right from opening a saved map ar even Field or value mapping.
- And above all if you have an exception due to which a single record in the import chunk fails then the entire set fails.
- So care must be taken to improve the performance of importing records.
- Which is done taking into consideration the following:
Areas to focus on improving performance during Importing:
1) The chunk size which defines the number of records to be imported at a time
2) The number of records processed parallely (MDIS settings)
3) The number of Fields Mapped
4) Number of Matching field used
5) The number of Validations and assignemnts running on the records etc
MDM Syndication:
- In the similar lines MDM performance also should be monitored when Harmonising data to the target systems
- Selecting the records to be syndicated using search criteria,Suppressing Unchanged records,Key mapping etc all afftects the MDM performance adversely.
You can in general create test scripts that will monitor MDM system performance in thes two prime areas as well as in MDM generak activities as well.Using different OS and different sizing.As MDM performance will differ according to the Software used in each case which includes the disk space,Cache and RAM as well.
You can Create test scripts on the following activities using differnt Configurations and thus compare and test teh performance of teh MDM system under different conditions with the expected output as against the actual output
- Testing mounting/unmounting repoisitory
- Loading/Unloading Rep
- Export/Import Schema
- Archieving/Unarchieving rep
- Creating Master/Slave rep
- Importing different sets of Records using manual and automatic method
- Syndicating different sets of rec using Manual and automatic method
Hope it helped
Thanks & Regards
