Master/Slave Server

Hey guys,
I had implemented a Java MATLAB server, which can handle MATLAB requests. Now I want to implement a master server which forwards the request to different slave server with a connection with MATLAB. This architecture should handle parallel requests.
What should I use?
RMI or JMS?
Thanx in advance!

That is the most efficient provided you have buffering, i.e. new DataInputStream(new BufferedInputStream(socket.getInputStream())) and new DataOutputStream(new BufferedOutputStream(socket.getOutputStream())).
The other techniques I listed are easier to program and higher-level, i.e. more powerful. If your application protocol is already designed you are already doing it the best way.

Weblogic Server Installation in Master/Slave

Hi All,
I have two linux server dedicated for weblogic server and I want to configure weblogic server on both the machines with one of them becomes a server and other machine will be a slave.
I have searched a lot but couldn't find any adequate information. Could someone please shed some light on how to install/configure weblogic server in master/slave fashion/pattern?
I appreciate for any help.
Thanks,
Sanjay

I think you need to do some reading of how domain's are organized with 1 Admin Server and 0 to many Managed Servers. The Managed Servers can be grouped into Clusters if you want. The servers can be across multiple machines. Check out the following link and perhaps the detail under clustering and respond if you have a more precise question.

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.

Problems installing an iFolder slave server

Hi,
I have an iFolder 3.8.4.0 master server configured and working with an AD server. I am now trying to add a second iFolder server as a slave in this iFolder domain. I'm running simias-server-setup and choosing "Y" when I get to the "Slave Server?" prompt. I'm putting in the same iFolder admin user and proxy user and passwords that I used for the master server. However, I get a failure at the end that indicates a credential error. Since the conversation is SSL-encrypted, I can't get much useful information in a WireShark trace. I should note on this same server, if I configure it as another master, it works perfectly against the AD server with SSL, so I'd have to believe the SSL cert for the AD server is properly imported. Is there any type of debug logging I can enable or more detailed output tracing I can do to determine why this is failing?
Here is the error at the end of the simias-server-setup script:

In troubleshooting this error, I've noticed that when I re-run the simias-server-setup and point to the existing location of the Simias.config file that was partially created, when it gets to the point where it asks the admin user dn, it inserts an additional "dc=test" in the string below when it auto-suggests the admin user in [brackets]:
cn=ifadmin,cn=Users,dc=test,dc=test,dc=wwt,dc=loca l
I found this line in the master server's Simias.config file and corrected it to reflect the proper dn for the ifadmin user:
cn=ifadmin,cn=Users,dc=test,dc=wwt,dc=local
I then re-ran the simais-server-setup, and this time it auto-suggested the correct path, however it fails with a different error that states the admin user is in an invalid context, and it shows the "cn" of Users as an "ou":
cn=ifadmin,ou=Users,dc=test,dc=wwt,dc=local
So something is different between the master and slave configuration in the setup program, but I can't tell what I need to enter to make it work. Any suggestions would be greatly appreciated!!
Best regards,
Greg

I was eventually able to resolve this issue myself. In an effort to help someone else if they should have the same problem, I will relay the details. What I ended up doing is opening the port in my firewall between the iFolder server and the AD server to allow LDAP cleartext (389) and then running a WireShark trace on the AD server to see what was actually going on. As is typical with software installation problems, the problem turned out to be rather simple, however the logs didn't really give enough detail as to what was failing (see above, which is all I got when it failed).
I had already found out anecdotally when re-running the install script that I had one typo in the master iFolder server's Simias.config file (an extra "dc=test" somehow got inserted into the path of the "iFolder admin user" (ifadmin in our case)):
cn=ifadmin,cn=Users,dc=test,dc=test,dc=wwt,dc=loca l
I found this line in the master server's Simias.config file and corrected it to reflect the proper dn for the ifadmin user:
cn=ifadmin,cn=Users,dc=test,dc=wwt,dc=local
I then re-ran the Simias-server-setup, and this time it auto-suggested the correct path, however it fails with a different error that states the admin user is in an invalid context, and it shows the "cn" of Users as an "ou":
cn=ifadmin,ou=Users,dc=test,dc=wwt,dc=local
What I didn't see until I did the wireshark trace is that after the slave server contacts the master server on it's SOAP URL, it pulls down the LDAP search contexts that are configured on the master, and it then tries to verify each one against the LDAP server. If it gets to one that does not verify, it bails and ends with the "LDAP Credentials" error seen on my earlier post. The thing I was confused on, is the "second" error shown just above, where it changes "cn=Users" to "ou=Users" in the dn for the ifadmin user. That turned out to be another line in the LDAP search contexts pulled from the master's Simias.config file. That was configured in the file as "ou=Users,dc=test,dc=wwt,dc=local". Someone familiar with LDAP and eDirectory, like myself, won't immediately find anything wrong with that, since "users" is a container, and in our way of thinking really is an "OU". For AD, for whatever stupid reason, Microsoft decided that the "users" container is a "CN", whereas the "groups" container is an "OU". Nice consistency. My Master server worked with this typo, because we don't have any production users under the "CN=users..." container (except ifadmin, which is called out by FQDN earlier in the config file), so it never needs to search in that container anyway. In the WireShark trace, you could see the AD server failing on validation of that OU (err, I mean CN) of "Users", and that is where the simias-server-setup script bombed. An extra properly-worded line of explanation in the setup script would have prevented a few hours of hair-pulling, but at least it's working now. Hope it helps someone in the future.

How to make two standalone oracle databases into master/slave relationship

i'm not talking about RAC...
is there any way to make two oracle databases into master/slave relationship? one is hot one is cold, when the hot one is down, the cold one automatically picks up? and of course two databases are in sync all the time.
any experience?

DataGuard is an enterprise edition feature.
You could roll your own standby database by cloning the production system to a backup server and writing scripts that copy the archived log files from the primary to the standby and that apply the archived logs on the standby. Of course, the transactions that had been applied to the primary that were still in the primary's redo logs would be lost if the primary were to fail. DataGuard provides options to keep the standby more closely in sync with the standby to reduce or eliminate that risk, which is one of the reasons that it's an enterprise edition feature.
If you're on Windows, Oracle FailSafe may also be something to look at.

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.

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,
Priti

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

Procedure changing master vpn server ip

hi,
I have a master vpn server with two vpn slaves.
the master is bordermanager 3.9.1 and the slaves are 3.9.1 and 3.8.5
We get a new subnet, so the public ip of the bordermanager will change.
I miss a procedure how to do this.
The slaves are in other countries.
regards,
Marcel

Hi,
Thanks for your answer.
All my borders are in the same tree and have their own partition. The slaves
are master of their own partition.
Are there any issues, which could lead to a problem ?
I mean I can not test this and it is a production environment.
regards,
Marcel

LMS 3.2-2.6 : migration and master/slave

Hi,
Customer has 2 LMS 2.6 standalone server, server A and server B
He wants to migrate both to 3.2 and he will have a new LMS 3.2 server C.
He would like to have server C master and server A and B slaves.
Do you think that we can migrate server A and B to LMS 3.2
Then, configure server C as master and server A and B as slaves without lost DCR data from server A and B ?
Many thanks, Elisabeth

No, this will not be possible. When you demote A and B to slaves, their DCRs will be overwritten by the new DCR on C. You can maintain the consolidated device list, but not the application data.

MASTER/SLAVE PATTERN: how to stop slave loop without stop main loop

Hi All, I am studying the master/slave loop and saw an examples are like this (only master block shows)
From this case, as I understand, if we click "set" button, slave loop will run. If we click this button again to mak it "Flase", the slave loop will be stopped as well as the main loop will be stopped as well.
Now if I have a multi-function main loop, I just want to start or stop slave loop when click "set" button, how can I do it? Thank you very much!

Your understanding is completely wrong. There is nothing in the image you show that would stop either loop. In this situation the "set" button would normally have a latching mechanical action, meaning that when it is pushed, it will stay true until it is read once, at which point it will return to false. Placing the control terminal inside the event case causes the terminal to be read and resets the button to false. With a latching mechanical action, there will be only one event generated even though the boolean will change value twice (from false to true, and from true to false). You'll never have a situation where you push the button once to set it true, and again to set it false. However, even if the mechanical action is switching, not latching, it still won't make a difference here - the event case does the same thing whenever the value changes, regardless of whether it's true or false.

Master/Slave Settings?

Hello Everyone. I need a little guidance here. The original HD in my B&W, Rev 2, is a Maxtor 6.03GB, ATA, Model 90648D3. I have it partitioned, running Classic and OS 10.2.8. I also have a second SCSI drive, a Quantum Atlas 35GB that I've been using as storage but it's almost full. I decided to get a large HD so I recently purchased a Seagate Cheetah 73GB Ultra-2 SCSI. The drive is an 80 pin but came with a 68 pin SCSI adapter. i thought that the two SCSI drives, with different IDs of course, would work so I installed the drive, thinking that since it was SCSI that I wouldn't have the Master/Slave issue, however I can't boot from the new drive at all. I've tried everything, short of standing on my head, with no success. I would really like to have classic on one of the drives and Tiger on the other but the drives only show up when I reconnect the Maxtor and boot from it. Does anyone know what the problem is here?
As always, any help is always appreciated! Thank you.

Ummm,
Look like you did all the step correctly, but do you use an upgrade card?, because I saw it on your specs at the bottom of youe thread that "B&W G3 .. upgraded to G4", if that is so you are out of luck base on this page :
http://www.apple.com/macosx/techspecs/
Maybe somebody would have a trick to install it using emulator software like xfacto or else, but I haven't try that and I heard it will chunk or disable some of Tiger feature, so what is the point of using Tiger if it is half a man it used to be..
Try to use your original processor first to install the system and after that, restart while pressing the mouse to pop the installer disk out, and press option to give you the option for start up disk. if you are too late, just restart again (after you take the installation disk out) by pressing the reset button or pull and plug back the power cable (not recommended) and hit option key until it give you start up disk option.
IF it still not coming up, maybe tiger doesn't support either your hd or scsi card for boot up.
Hope it help now.

Master-Slave design Implementation

Hi,
I am trying to design a master-slave system with the following attributes:
1. Linux Master box having all the Java code.
2. At least two Windows XP Professional Slave boxes (no Java code on any of these)
Front end screens on Master would contain a text fields for IP Address and Java program to be executed. On a click of button, the slaves (who's IP Address was entered in the Master screen text field) would get the request to execute the given Java program, a given number of times. Once executed, each slave would turn the results in to the master via a file. After all the slaves have turned in their results, Master would consolidate the results, work another program on the results and re-delegate tasks to the slaves. The steps would stop iterating only when an exit criteria specified by the program has been met.
If we were to restrict all code to only the master box, what could be the lucidly possible ways to achieve this design?
Thanks!

You will need some machanism to send the programs to slaves atleast temperarly in order to be executed there.
Or you will have to provide a vay for the programs to access the required respurces (files , ect..) in the slaves and let the programs run in the master.

What DQS column locations & DQ master/slave settings do I pick in 10.1 EDK?

I am attempting to duplicate the FPGA synthesis flow using XST and ACE to boot Solaris on a Digilent board. I encounter some steps, warnings, and errors listed below that are not covered in the documentation I have. In following section 6.2 of the DV Guide,

Hi sparcMT1,
I'm not sure what the problem is. When we read in the 9.2 project into 10.1, it updated cores with very few problems.
One thing you can try is to do only the automatic updates. For example, even though XPS says that "these changes need to be made by the user", just leave the MPMC with version 3.0. I'm looking at one of our projects, and it seems that we did just that.

Satellite Pro 6100: What drive and connection is supported - Master, Slave or CSEL?

Hello,
i want to install a Pioneer DVR-K14L DVD writer.
After the installation, the notebook show me an
error during the initialisation.
It is possible to use this type of Slimline DVD writer?
What kind of modus is important (master, slave or cable-select)?
Thank you and
best regards

Hi
I assume you get an IDE# 1 error message. Am I right?
The fact is that not all drives are compatible with the notebooks.
I'm not sure which settings the supported drive should have. But I surmise it's could be a CSEL.
However, I have found this DVD-RW drive which should be compatible; the part number is P000366780

But unfortunately, there is nothing about the pin assignment and the settings.
If you want to be 100% sure about the supported devices on your notebook so you should ask the Toshiba service partner in your country for the details
