Synchronizing Slave Repository

I have Server A with Repository Vendor running SP3 version. I have Server B running SP3 version. I created a Slave for the Vendor Repository on Server B . When I mount the repository on Server B and run Synchronization I get the error "Winsock error on gethost... functions".
How do I resolve this issue ?

Hello Subbu,
Did you have to setup the port in services file ? Have you installed Sapgui frontend on the computer where MDM slave is running ?
Let me know if there is any way I can find how the port can be unlocked.
Where did you find the info regarding MDM port
I mounted the slave on port 3000 should I mount on 20001 ?
Thanks for your reply

Error in Synchronizing Slave Repository

Hi All,
I've created a Master / Slave pattern and when i make any changes in the Master and Synchronize the slave i get the following error:
"Unable to retrieve synchronization data from master repository. See the Assertion Log for more information."
In the assertion log it shows the error "When requesting pending changes, received the following error from the master MDS: Error opening file (code 2147614722)."
Can anyone help me figure out why this is happening and which file it is not able to open?
Thanks and Regards,
Seema.

Hi Prakash,
I tried to synchronize the slave of another repository. but this time i got the following error in the Assertion Log:
Error:Unable to open transaction log file C:\PROGRA1\SAPMDM1.5\Server\Modifications\REP_QUIZDTPXP-SERANE%SIMMSQL_8_16_4_3.xct because of error: Error opening file (code 2147614722).
I tried the find the .xct file but i couldn't find any. I'm working on Windows OS and my MDM server version is 5.5.42.66
Can u pls tell me where can i find this .xct file???

Syndication from a slave repository

Hello colleagues:
Has anyone tryed syndicating from a slave repository?
I've found that I cannot even open the syndication map. If I try to create a map it won't do it. I guess it is because the read only attribute from a slave repository.
If anyone knows if this is possible or not, please confirm.
Thank you.
Kind regards,
Jorge.

Hi Jorge,
Slave is a read-only repository.
My question is why you have to use slave repository for syndication. Conceptually I feel you should syndicate from the master not from slave.
Because you will be synchronizing the slave from master repository periodically.
Thanks and Regards

Difficulties when creating a slave repository on MDM 7.1

Hi Experts,
We're trying to create a Slave repository on MDM 7.1, but when trying to connect to the other DBMS a message shows up saying that it's unable to connect with Database Server.
I went to the MDM log and found the following message:
Service 'MQ0', Schema 'system', ERROR CODE=12154 ||| ORA-12154: TNS:could not resolve the connect identifier specified Last CMD:
Important information:
The servers are different, one for the master and the other for slave. (the DB is also in each correspondent server).
Both servers are on the same network.
The Oracle Listener is up and working, we could telnet it.
Does anybody faced with something similar?
Thanks for the help

Slave repository synchronization

Hello,
We don't want to manually sync slave repository through MDM console or MDM CLIX. I found command "CLIX repSynchronize <MdsHostSpec> <slaveRepositorySpec> <Credentials> [-D]" but is there a parameter we can set to sync slave repository automatically after every fix time interval or is there a way to synchronize slave repository automatically?
Thanks,
Urvi

Hi,
On which MDS system i need to run this command? MDM Master or MDM slave.
CLIX repSynchronize <MdsHostSpec> <slaveRepositorySpec> <Credentials> [-D]
Can you please help me with values for <MdsHostSpec> <slaveRepositorySpec> <Credentials> parameteres?
clix repSynchronize masterhost:<sidadm password> <slave repository>:<slave host>:<O- for oracle>:<slave db user id>:<slave db user's pwd> <slave repo user>:<slave repo user's pwd>
Is above correct?
I tried this on master server with Master SIDADM user and also same command i tried on slave server with slave SIDADM user, but I am getting below(same error on both):
Loading '/usr/sap/MWP/MDS00/exe/LangStrings/ADT.lang' (English [US])...

Please tell me which user I am putting wrong in above command?

Master-Slave Repository locking problem

Hi,
We are implementing SRM-MDM Catalog 3.0. I have few questions regarding MAster-Slave scenario.
1. At the time of importing supplier catalog data into Master Repository through Import Manager, the Master Repository will be locked for Read Access through SRM-MDM Catalog Search UI???
2. At the time of Master-Slave synchroniztion, which repository will be locked? Master or Slave or both? If both repositories are locked for searching, that means at that particular time, end users can't perform search.
3. If we go for Master-Slave scenario, how could I make my Master Repository Highly Available? As per SAP Note # 1170807, it is recommended that SRM-MDM catalog Search UI is mapped to work with slave repository. It means latest data will be there in Master Repsoitory and will only be available after synchronization.
4. If we create one or two slave repositories on the same server where we have master repository, how much extra resources will be required?
Thanks,
Anshuk Saxena

Hi Anshuk,
1. At the time of importing supplier catalog data into Master Repository through Import Manager, the Master Repository will be locked for Read Access through SRM-MDM Catalog Search UI???
Yes, at that time Master repo will locked and if you are using master slave scenario thencatalo 3.0 will log in slave repository.Basically MDM catalog 3.0 first find available slave then only move to master.
2. At the time of Master-Slave synchroniztion, which repository will be locked? Master or Slave or both? If both repositories are locked for searching, that means at that particular time, end users can't perform search
At this time slave that is under synchronization proces will locked not master.
. If we go for Master-Slave scenario, how could I make my Master Repository Highly Available? As per SAP Note # 1170807, it is recommended that SRM-MDM catalog Search UI is mapped to work with slave repository. It means latest data will be there in Master Repsoitory and will only be available after synchronization.
YES latest data in master only.High availability can achieved by what user set the synchronization frequency after each import or when.It is up to user only.
4. If we create one or two slave repositories on the same server where we have master repository, how much extra resources will be required?
Again its up to user.they can maintain all repository on same server or all on different server.But preferable is atleast maintain master at different server.

Difference between Slave reporsitory and Duplicate repository

Please so kindly, help to explain the following question. Thanks!
1)Why use the port during Repository creation? Is the port connected to XI?
2) Who can explain inside what the difference between Slave reporsitory and Duplicate repository?
Example like below:
When we create a salve repository named "Test002" that was based on repositorty "Test001" (Port:"2345"), after creation, system shows the port for Test 002 is "2035" in Server level, the question is that how the system define the port? Normally, during repository creation, we have to enter a port by manually, but why, when we create a salve repository, system give us the port randomly.
3) The same question like above about repository depulication.

Hi Alfred
1. I assume you're referring to the port number for a repository. Some of the MDM utilities connect to a repository which is identified by a port number. This is a TCP port number. Each repository on a server must have a unique port, and they ports should be spaced 5 ports apart (i.e. if repository A uses port 2000, then repository B should use port 2005 - 2001, 2002, 2003 and 2004 can be used by repository A.)
The port is not connected to XI.
2. A slave repository is a read-only point-in-time copy of the master. The slave repository / repositories can be refreshed from the master as required. The slave is aware of who its master is. The master-slave scenario is utilised to create redundancy.
A duplicated repository is simply a copy of a repository. It is not read-only, and has no link to it's "source" repository.
Port numbers for new repositories are not random - they are calculated, starting from 2000 in increments of 5.
3. Neither creating a slave nor creating a duplicate repository asks for a port number. The number used in both instances is calculated.

Synchronize Slave issue

Hey all,
Any ideas on what is going here. I just created this new slave from the Master repository last night. Today when I try to synchronize the two, I get a fun little error: "Unable to retrieve synchronization data from master repository."
When I check the Assertion log, I find: "Error: When retrieving a change for synchronization, received the following error from the master MDS: Error seeking file pos (code 2147614726)."
The sync updates the slave repository with the new updates to the catalog that are changed in the master repository, fyi.
Again, any help on this would be great. Thanks,
Ryan

Hi Ryan,
All slave repositories should be mounted on hosts running the same version (build number) of MDM Server software as their master repository. Changes made to a master repository running a different version of the MDM Server than a slave repository can not be synchronized by the slave.

Clix for Master-Slave Synchronisation

Hi SDNers,
I am using the Slave and Master reposirotries. If anyone has used CLIX for the Master-Slave synchronisation, please give the related commands. File would be of greater help.
Any suggestions are also welcome.
Thanks & Regards,

Hi Priti
Copying from help.sap
Sharing and Swapping Slave Repositories
You can use the repShare command to make a slave repository u201Cshareableu201D so that multiple MDM Servers can load it. Conversely, you must use the repExclusive command to return the slave to an unshared state before synchronizing it, so that a single MDM Server can issue the synchronization command.
An alternative to this methodology is to leave the single slave shared and loaded, and then:
       1.      Create a new slave from the Master.
       2.      Make that new slave u201Cshareable.u201D
       3.      Load the new slave without ports in the background using the repPreload command on each MDM Server that acts as a host.
       4.      After each host completes the background load, use the repSwap command to swap the new slave for the old on the same port.
for more details refer to relevant sections in help.sap.com

Master-Slave Problem: Please Help

I am having a problem getting master/slave repositories set up for synchronization.
My MDM server environment is Solaris with Oracle 10.2 database.
MDM version is 5.5.41.58 (5.5 SP05).
I create a repository. I unarchive my data into it. I create a slave repository from it. I go into Data Manager and change the description of one product in the master repository. In the Console, the server log has the following message:
Master Server failed to log change because of error: The new transaction id is less than the last transaction id. (code 4289454080).
Has anybody had the same issue? Any clues as to what the problem and/or fix is?
Thanks in advance.

Hello Simon,
Thank you for taking the time to respond.
The unarchive process involved the following: we have a production catalog running MDM 4.0.58. We had an SAP consultant assist in migrating our catalog to MDM 5.5 SP05. This was done using a local server running Windows and SQL Server. From the Windows MDM 5.5, I made an archive. I transferred it to the Solaris/Oracle environment. Using the Console I did the unarchive.
One interesting thing to note: when MDM 5.5 SP05 was installed on Solaris, the "Modifications" directory was not created. Initial attempts to synchronize gave a different error. I determined that the directory was missing and had our data center admin create it. He then stopped the MDM server and restarted it. Then I deleted my master and slave repositories and started over. And then got the error referenced above.
Running the CLIX command gives the following:
52 for the master and 50 for the slave.
In the server log, the only errors I see (other than the one about the transaction id's) are when starting the master and slave repositories I see:
SERVICE 'xxx', SCHEMA 'yyy', ERROR CODE=1002 ||| ORA-01002: fetch out of sequence Last CMD: SELECT PermanentId, Id, F153, F154, F163, F164, F353, F387, F414 FROM A2i_40
In the assertion log, there is nothing at the time of creating the slave. When starting the slave, there are many messages relating to accelerators. At the time when I was changing the data in the master, there are messages from A2iIndexedTransactions.cpp (lines 647, 119, 96, and 231).
If you need any more info, let me know.
Thanks again for your help.

SRM MDM Catalogue 3.0 Slave in unknown status

Hi All,
PLease could someone guide me here, I have created a SRM MDM master and slave configuration. the server was restarted and now the Slave repository has a black line through the top and you are unable to syncronize, normalize or perform any functions on the slave.
Kind Regards
Grant.

Hi All,
I got the official word back from SAP there is no apparent way to correct the repository, the official answer can be found in th e MDM console reference guide Release: MDM 7.1 SP07 May 12, 2011, under the section BROKEN MASTER/SLAVE REPOSITORIES, to sum it up you need to unload the master repository then normalize it unmount the slave and recreated a new slave from the master.
Kind Regards

Repository is invalid after crash of the MDM Server in MDM 7.1

Hello,
after a crash of our MDS the slave repository is invalid. When I tried to connect to the repository I am getting an error like
Repository connect failed
Error: The MDM repository is Invalid
I tired to delete but I am not able to delete also. While deleteing it is giving an error like
The MDM repository is in read-only mode
The master repository on the same db server and MDS server works fine. I'm also unable to unmount the repository and note 1325833 was not helpful.
Any Help or Solution?
Thanks

Hello Patrick G.
Sometimes we had some situation.
Create your master repository archive .
Connect to database directly and drop you slave repository tablespace.
Than create slave repository again.
in Database you repositories have names like [repository_name] M000 or [repositoryname] _Z000

The MDM repository is in read-only mode

Hi Experts,
In our environment we have a Master ans Slave repository and the synchronization is being scheduled daily.
Now we understand from the MDIS logs of the Master repository that the repository is in Read-Only mode and none of the records can be updated / created.
We have tried restarting the repository too.
Please advice.
Thanks,
Sridhar T A

Chander,
We get Check/Verify Option only after repository is unarchived/created. So, this can not be applied in Maria's case....
Maria,
Please let us know what version of MDM you are using.. Are you sharing database for MDM with other systems too??
Also, can you check MDM logs and provide detailed error message from logs...You can check MDM server logs either from Console or On MDM server log directory...
This information will help..
Please also try this after setting following entry in MDS.INI file:
Unarchive Ignore Language Count=True
Best Regards,
Shiv

Load repository without (TCP/IP) port binding?

Hello all,
According to the MDM100 course, it is possible to load repositories without port binding (for port flip-over). But how do I do this?
When I try to erase the port number of the (unloaded) repository, a message informs me that a port number between 2000 and 9999 is required.
Is this option gone in SP05?
Kind regards,
Dennis klemann

Hi Charan,
You're right for typical use, but I'm working on a high availability scenario. Basically, it should be possible to load a slave repository without port binding. In case the master repository fails, the slave can immediately take over (by assigning the port of the master), at least in read-only mode - but better than nothing and external applications don't have to be reconfigured.
When the master repository is up again, it can take over the port.
For bigger installations, a clustering system is probably better suited, though...
Kind regards,
Dennis
