Replication between linux on z (zLinux) and linux x86

Hey guys,
I'm looking for the best/recommended solution to setup replication between Linux on z (s390x) which is a big-endian platform and Linux x86 which is small-endian. I know Dataguard would not work but what would you suggest instead?
Source DB: 10.2.0.4 on Linux x86_64
Destination DB: 10.2.0.4 on Linux s390x

What are requirements for a replication?
- max latency time
- volume of changes (bytes/time)
- one direction / by-direction / multi-direction
- synchronous/asynchronous
- some specific/exotic data types
- is any transformation of values required
- is any filtering of rows based on column values or other criteria like user or time required
- other?

Configure replication between directory server 5.1 and 5.2

we have two directory servers running on different machine 5.1 and new 5.2. All database have been successfully backup and restore from 5.1 to new 5.2. In this scenario, we would like to setup 5.1 and new 5.2 D.S as multi-master replication.
As described in the sun Documentation, we have copy few ldif file from new 5.2 to 5.1 so that both schema are up to date.
The new instance of 5.2 is running fine. However, on the other hand, 5.1 has a problem to start the server as show in the following below.
# ./start-slapd
[31/May/2005:14:07:43 +0800] dse - The entry cn=schema in file /usr/iplanet/servers/slapd-ifpdev02/config/schema/50ns-admin.ldif is invalid, error code 21 (Invalid syntax) - object class nsAdminServer: Unknown required attribute type "nsServerID"
[31/May/2005:14:07:43 +0800] dse - Please edit the file to correct the reported problems and then restart the server.
Any help from you guys are greatly appreciated.

I recommened that you read the Release Notes of DS5.2, there are some notes on Replication between 5.1 and 5.2.
===
In Directory Server 5.2, the schema file 11rfc2307.ldif has been altered to conform to rfc2307. If replication is enabled between 5.2 servers and 5.1 servers, the rfc2307 schema MUST be corrected on the 5.1 servers, or replication will not work correctly.
Workaround
To ensure correct replication between Directory Server 5.2 and Directory Server 5.1, perform the following tasks:
* For zip installations, remove the 10rfc2307.ldif file from the 5.1 schema directory and copy the 5.2 11rfc2307.ldif file to the 5.1 schema directory. (5.1 Directory Server Solaris packages already include this change.)
* Copy the following files from the 5.2 schema directory into the 5.1 schema directory, overwriting the 5.1 copies of these files:
11rfc2307.ldif, 50ns-msg.ldif, 30ns-common.ldif, 50ns-directory.ldif, 50ns-mail.ldif, 50ns-mlm.ldif, 50ns-admin.ldif, 50ns-certificate.ldif, 50ns-netshare.ldif, 50ns-legacy.ldif, and 20subscriber.ldif.
* Restart the Directory Server 5.1 server.
* In the Directory Server 5.2 server, set the nsslapd-schema-repl-useronly attribute under cn=config to on.
* Configure replication on both servers.
* Initialize the replicas.
===
Also search for "migrate" or "repl" or "5.1" in Release Notes and read the relevant information.

Replication between 2 node RAC environment and standalone

I would like to find out if we can setup replication between a (2 node) RAC environment and standalone database located at different location. Any help regarding this would be greatly appreciated.

Thanks for the reply.
Consider for a moment I cannot implement dataguard/stream -- because I believe both involves licensing issue --- now only option left is writing my own code. If I right my own code what are the prerequisites for this and what do I have to keep in (technically)mind before i start implementing this. Any help or any lead would be greatly appreciated.

Multi-Master-Replication between 6.3 (32bit) and 11g (64bit) possible?

Hello,
is it possible to run a multi-master-replication between a 6.3 32bit and a 11g 64bit Directory Server instance (both on linux)? I'm running into a
B1 - Client request contains an ASN.1 BER tag that is corrupt or connection aborted
message on the 'dsconf accord-repl-agmt' step, while 'dsconf info' works for both servers.
Yours
Karsten
Edited by: 813510 on 19.11.2010 01:55

MMR works between 6.3 and 11g and is platform-agnostic so it works across platforms.
Please check if the max-ber-size parameter is identical on both servers.

Multi master replication between 5.2 and 6.3.1

I have a setup in which I have a master running version 5.2 and about 15 consumers ( slaves) all of which have been upgraded to 6.3.1 . I now want to create a multi master topology by promoting one of these consumers to be a master and still keep the 5.2 in use as we have a bunch of other applications that depend on the 5.2 instance. Our master has two suffixes. The master server is also the CA cert authority for all the consumers . After reading the docs I narrowed down the procedure to be
1. Promote one of the 6.3.1 consumers to hub and then to master using the dsconf promote-repl commands. The problem here is that I am not sure how I can create a single consumer that can slave both the suffixes. We currently have them being slaved to different consumers.
Also do I need to stop the existing replication between the 5.2 master and the would be 6.3.1 master to promote to hub and master.
2. Set the replication manager manually or using dsconf set-server-prop on the new 6.3.1 master .
3. Create a new replication agreement from 5.2 to 6.3.1 master without initializing. (using java console)
4. Create new replication agreement from 6.3.1 to 5.2 (using command line)
5. Create new repl agreements between the new 6.3.1 master and all the other consumers. For this do I need to first disable all the agreements between 5.2 and 6.3 or can I create new agreements without disabling the old ones?
6. Initialize 6.3.1 from the 5.2 master.
My biggest concern at this point is surrounding the ssl certs and the existing trusts the consumers have with the 5.2 master. Currently my 5.2 server acts as the CA authority for our certificate management with the ldap slaves. How can I migrate this functionality to the new server and also will this affect how the slaves communicate to the new master server ?
Thanks in advance.

Thanks Marco and Chris for the replies.
I was able to get around the message by first manually initialzing the new slave using an ldif of the ou from the master , using dscc to change the default replication manager account to connect and finally editing the dse.ldif to enter the correct crypt hash for the new repl manager password. After these steps I was able to successfully set up replication to the second ou and also promote it to hub and master ( I had to repeat the steps after promotion of the slave to master as somehow it reset replication manager settings when I did that).
So right now, I have a 5.2 master with two ou's replicating to about 15 consumers.
I promoted one of these to be a second master (from consumer to hub to master). Replication is setup from 5.2 to 6.3 master but not the other way round.
I am a little bit nervous setting up replication the other way round as this is our production environment and do want to end up blowing up my production instance. The steps I plan on taking are , from the new master server
1. dsconf create-repl-agmt -p 389 dc=xxxxx,dc=com <5.2-master>:389
2. dsconf set-repl-agmt-prop -p 389 dc=xxxxx,dc=com <5.2-master>:389 auth-pwd-file:<passwd_file.txt>
I am assuming I can do all of this while the instances are up. Also in the above, does create-repl-agmt just create the agreement or does it also initalize the consumer with the data ? I want to ensure I do not initialize my 5.2 master with my 6.3 data.
Thanks again

SCCM 2012 Replication between Central Admin Site and all Primary Sites is failing

Let me start by saying I have made a mistake and now I am paying for it and attempting to fix it. All of our SCCM servers are virtual and exist on an ESX environment. The mistake I made is I restored our Central Admin Site from a backup without also
restoring the two Primary Sites at the same time. Now the databases between the sites simply refuse to synchronize. I can run the Replication Link Analyzer until I'm blue in the face and even though the data gets replicated once, the replication immediately
breaks and fails after that.
Regrettably I no longer have access to backups that would take me back to a point where the three servers were happy. The problem there is our ESX administrator only keeps a limited number of backups per server (we have in excess of 180 virtual servers in
our ESX environment) and the backups from a point in time where they worked is no longer available.
As I have said I have tried running the Replication Link Analyzer many times. I have also tried going into the SQL server console and running the stored procedure spDrsSendReplicationInvalid.
Can anyone provide me with any assistance on how best to restore replication between the Central Admin server and the two Primary servers?

Just an addition: the option called "Recover central administration site:
Then specify the FQDN of a
Reference primary site" is the one to try first.

Problems using RMI between linux and windows.

I have problems using RMI between linux and windows.
This is my scenario:
- Server running on linux pc
- Clients running on linux and windows PCs
When a linux client disconnect, first time that server try to call a method of this client, a rmi.ConnectException is generated so server can catch it, mark the client as disconnected and won't communicate with it anymore.
When a windows client (tested on XP and Vista) disconnect, no exceptions are generated (I tryed to catch all the rmi exception), so server cannot know that client is disconnected and hangs trying to communicate with the windows client.
Any ideas?
Thanks in advance.

Thanks for your reply.
Yes, we are implementing a sort of callback using Publisher (remote Observable) and Subscribers (remote Observer). The pattern and relative code is very well described at this link: http://www2.sys-con.com/ITSG/virtualcd/java/archives/0210/schwell/index.html (look at the notifySubscribers(Object pub, Object code) function).
Everything works great, the only problem is this: when a Publisher that reside on a Linux server try to notify something to a "dead" Subscriber that reside on a Windows PC it does't receive the usual ConnectException and so tends to hang.
As a workaround we have solved now starting a new Thread for each update (notification), so only that Thread is blocked (until the timeout i guess) and not the entire "notifySubscribers" function (that contact all the Subscribers).
Beside this, using the Thread seem to give us better performance.
Is that missed ConnectException a bug? Or we are just making some mistake?
We are using java 6 and when both client and server are Linux or Windows the ConnectException always happen and we don't have any problem.
I hope that now this information are enough.
Thanks again and greetings.
O.C.

What different between the OTN download version and the CD version of 8i for linux?

Does there have any different between the OTN download version and the CD copy version of 8i?
Can I use the OTN download version for production environment?

They are the same.
Can I use the OTN download version for production environment? I think if you read the download license agreement it specifically says you can't use the software in a production environment.

SQL Database replication between Primary and DR site

Hi,
We are setting up a DR Site, for our Production SAP system.
At present the curren setup for Production SAP system are as follows.
SAP ERP 2005 (SAP ECC 6.), ABAP+JAVA on Windows with MS SQL Server
2005.
Data are stored on SAN and SAP installed on MSCS Cluster enviornment.
For Setting up the DR site, we are setting up Central System
installation and replication will be configured between SAP
Production/Primary system and DR site.
We are shoadwing at our test setup and facing below replication issues
while setting up transactional replication in MS SQL server 2005.
1. At present 78716 articles are available on Production Database, and
SQL fails the replication publication after 59000 articles.
We open the ticket with Microsoft and below are the suggestion provided
by them.
1. Microsfot suggest to prepare 2\3 publications for total number of
tables, 1 publication for all Views and 1 publication for SPs,
Functions and Data types with single Distributor Agent. Distribution Agent will
take care of propagating changes in the tables across the publications.
2. All related tables (Parent child relationship) to be published on
one publication.
3. It would recommend to create 4 publications: 2 for the tables, 1 for
the views and the other for the stored procedures. This would ensure
better manageability.
The main concerns here is about splitting the tables into two different
sets with about 30,000 in one of the publications and the rest in the
second publication.
You will have to make sure that all the dependant tables are included
in the same publication. Since this database is a SAP database, requesting to provide information as follows.
1. Identify and split the entire set of table into two/three groups.
2. How to publish dynamic tables (The tables which get created post
publication process).

Hi,
for database mirroring and log shipping there a several very good whitepapers and other documents out there:
[http://download.microsoft.com/download/d/9/4/d948f981-926e-40fa-a026-5bfcf076d9b9/SAP_SQL2005_Best%20Practices.doc]

[http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032297524&EventCategory=5&culture=en-US&CountryCode=US]
[http://sqlcat.com/whitepapers/archive/2007/11/19/database-mirroring-best-practices-and-performance-considerations.aspx]
Furthermore see note 965908 for this.
The needed bandwidth depends on the amount of log you create in a given timeframe. Internet bandwidth can be suffient, if you don't generate much log (btw, i don't understand the term RTD is 220).
In the log shipping scenario you can run the DR site in standby mode, then a readonly access (as DBCC etc.) is possible.

Replication between Oracle Server and MS SQL Server

Hello,
Does anybody know of a well known or reliable software that can do data replication between Oracle Server and Microsoft SQL server.
I suppose I can write my own version using Heterogenous Services in Oracle but I would like to know if such an automated replication between Oracle and SQL is available commercially.
Thank you.

It could be very interesting.Sorry Viacheslav, even I couldn't find anything for the same. I am not sure that it can be done or not, I haven't heard anyone in my contact doing so. The only place where I have seen Streams being used around me is within Oracle db only. May be someone else can help if he/she has done it.

Data Replication Between Sqlserver and Oracle11g using materialized view.

I have Sqlserver 2005 as my source and oracle11g as my target.I need to populate the target daily with change data from source.
for that we have created a dblink between sqlserver and oracle and replicated that table as a Materialized view in Oracle.
problem we are getting here is Fast refresh option is not available.each day it will pick full data from the source.
is there any way to use Fast refresh in this scenario??
Thanks in advance.

Replication between Oracle 7 and Oracle 10g. Is it possible?

Hello,
I have two DBs which exist on two different versions of Oracle (7.3.3 and 10g). Those DBs have different structures of tables, data from which can be casted from one structure to other. Can I organise bi-directional replication between those DBs. To make the point clear, can I replicate data from Oracle 7.3.3 to 10g and vice versa.
Duration of synchronization should be less than 1 minute.
I would be very pleased if somebody gives my a reference on online oracle documentation because I can't find answer in it to my questions.
If the possability of application of replication is questionable, can you give an advice which technology I have to apply in my situation. For instance, perhaps, it is convenient to use triggers.
Thank you.

Hi,
ObjectMMRS (http://www.object.com.br/wiki) can make what you need, replicate data between different Oracle database versions and between Oracle and other database brands too.
Documentation still in Portuguese only (Translation in progress) but I can help you install and try, maybe one or two days of work and you will be able to replicate.
Contact me at [email protected] if you want to try the ObjectMMRS (low cost replication software suite), no technical support fees for trial, and 30 days license expiration.

REPLICATION BETWEEN ORACLE 10g and postgresql/MySQL/MSSQL SERVER??

Hi Friends.
I want to know if there are a manner of replication between ORACLE and (postgresql or mysql or mssqlserver).
Please, my email is [email protected]
Thanks
Manuel

Sure.
Are you talking about replicating data in one direction? If so, in which direction (Oracle to non-Oracle or non-Oracle to Oracle)? Or are you talking about bidirectional replication?
Which database do you want to be the "master" (i.e. initiate the push or pull of data)?
What sort of lag is acceptable? Minutes? Hours? Days?
