Doubt in GG replication

Hi All,
posting this thread in this section since i dont see much activity under replication thread
We have a Table level GG replication setup between source and target.
My question is, say suppose i create a DELETE Trigger on a table (which is under replication) in target, will it cause any issue in replication?
Thanks,
John

Sorry returning late to the thread.
In the source database the trigger will be active and function as normal. Golden Gate will capture the SQL the causes the trigger to fire in the source database and will replicate that SQL to the destination database. Golden Gate will also capture any changes made by the trigger in source database replicate those changes to the destination database.
If you do not suppress the trigger in the destination database then the following will take place. The SQL that fired the trigger will be executed in the destination database, thus re-firing the trigger destination. Any changes made by the trigger will happen twice in the destination database. Once by the SQL the other by the replication of any changes made by the trigger in the source database.
You are not going to loose any changes made because the SQL the fired the trigger and the changes made by the trigger are shipped to the destination.

URGENT: Doubt in vendor replication

hi,
i got an error i.e 1) <b>user sapuser is blocking organizational unit 50000xxx</b> 2) none of the purchasing org's in org, structure exist(inform system admin) while iam
replicating the vendor through in BBPGETVD pls send details imediatly to [email protected]
with regards to all

Hi,
1-Please exit the organisational structure transaction while replicating vendors .
If not, you are blocking the process.
2- You have to maintain a purchasing organizational strcuture in ppoma_bbp because all vendors that you create or replicate have to be linked to a purchasing organization.
replication will NOT work if you do not have any purchasing organization maintained in SRM organizational structure.
Kind regards,

Storage Replication

Hi,
I have some doubt on storage replication link configuration. we have two dc in different location and need to replicate entire data over a L3 MPLS link and we are using EMC Storage with RPA at both side.
Old DC is having 6509 in core/distribution and new DC is having N7k in core/distribution and we are planning to terminate L3 MPLS link on this core at both side. RPA will be connected to Core Switches.
I did not configure this before dont have any idea whether will it work or not and how do we connect RPA at both side over L3 link. Or do we required router must.
If anyone have this experience, please help me to established this link.

Your storage vendor should have published a white paper on implementing storage replication for Oracle ASM environments.
Ask for such a white paper from the sales person.

Database Replication

Hi,
what would be the perfect answer if any one ask what are the methods of database replication.
I really have doubt about the replication.
Is it cloning of existing DB using cold backup, RMAN uutility or exp/imp
OR
Is it disaster recovery solution like dataguard, RAC or stream.

The best answer as always comes from Oracle docs. Please refer to the following doc:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14226/repoverview.htm#sthref8
Replication is the process of copying and maintaining database objects, such as tables, in multiple databases that make up a distributed database system. Changes applied at one site are captured and stored locally before being forwarded and applied at each of the remote locations. Advanced Replication is a fully integrated feature of the Oracle server; it is not a separate server.
Replication uses distributed database technology to share data between multiple sites, but a replicated database and a distributed database are not the same. In a distributed database, data is available at many locations, but a particular table resides at only one location. For example, the employees table resides at only the ny.world database in a distributed database system that also includes the hk.world and la.world databases. Replication means that the same data is available at multiple locations. For example, the employees table is available at ny.world, hk.world, and la.world.

SAP CRM Middleware flow from R/3 to CRM

hi
I am new to CRM middleware I have some doubt about the replication from the R/3 to CRM.
I have some 4 basic questions Kindly help me out
1.in initial down lode how to know which object for which requirement? There is any list like these objects for this one?
2.when the initial download have to use and when the delta down lode have to use?
3.object creating is preferable option or not if yes in which condition we have to create the objects?
4.what is the difference between customizing objects and business objects? and when we have to use which object ?
wiht Regards,
prakesh..!

Hi Prakesh
Happy to hear that my answers were useful. Hope this new will solve your problem.
So let's reply to your new questions.
1) Yes it is the delta download. This means that you have already triggered the initial download. Now all changes or new creations are replicated into the CRM system. I do not suggest this approach. This is usually used when you have no other chance because this process is complex and very time consuming. I would suggest checking the BDoc before proceding with degugging the queue. Go to transaction code SMW01. Filter on time (when you made the change). You will find bdocwith a red or yellow traffic light. This means that data have been not processed in CRM system. You usually have an error message (just select the BDoc from the list and click the red button in the toolbar) attached to the BDoc that is explainatory of the error. Correct the error and reprocess the BDoc (there is a proper button).
2) To debug the queue go to transaction code SMQS and SMQR and deregistrate inbound and outbound queue in the CRM system. After you do this, apply the changes to the customer. You will find an inbound queue in transaction code SMQ2. Select the queue and click the last button in the header toolbar. You will process the flow in debug. Remember to register the queue when this is no more necessary otherwise you will have a mess in the system.
3) if you create new customer in CRM system, this are automatically replicated in the backend system basing on the scenario set. No additional tables are created. All the changes applied in the CRM system will be replicated in the backend with the same process except the Bdoc that are really CRM specific.
Hope this help you.

Design considerations with clustering

anybody have any docs (besides the weblogic ones)/comments on things to
          consider when designing an app/sys (jsp/serlvet/ejb) that will be deployed
          in cluster.

I too use stateful session beans when appropriate. My suggestion is to
          avoid clustering them (WL added the feature in 6.0). I don't doubt that the
          replication works, however a web-based architecture with HTTP session
          replication is typically sufficient and already expensive enough. Designing
          an application that requires EJB replication introduces a lot of variables
          that I believe are best avoided.

Timesten replication with multiple interfaces sharing the same hostname

Hi,
we have in our environment two Sun T2000 nodes, running SunOS 5.10 and hosting a TT server currently in Release 7.0.5.9.0, replicated between each other.
I would like to have some more information on the behavior of the replication w.r.t. network reliability when using two interfaces associated to the same hostname, the one used to define the replication element.
To make an example we have our nodes sharing this common /etc/hosts elements:
151.98.227.5 TBMAS10df2 TBMAS10df2-10 TBMAS10df2-ttrep
151.98.226.5 TBMAS10df2 TBMAS10df2-01 TBMAS10df2-ttrep
151.98.227.4 TBMAS9df1 TBMAS9df1-10 TBMAS9df1-ttrep
151.98.226.4 TBMAS9df1 TBMAS9df1-01 TBMAS9df1-ttrep
with the following element defined for replication:
ALTER REPLICATION REPLSCHEME
ADD ELEMENT HDF_GNP_CDPN_1 TABLE HDF_GNP_CDPN
CHECK CONFLICTS BY ROW TIMESTAMP
COLUMN ConflictResTimeStamp
REPORT TO '/sn/sps/HDF620/datamodel/tt41dataConflict.rpt'
MASTER tt41data ON "TBMAS9df1-ttrep"
SUBSCRIBER tt41data ON "TBMAS10df2-ttrep"
RETURN RECEIPT BY REQUEST
ADD ELEMENT HDF_GNP_CDPN_2 TABLE HDF_GNP_CDPN
CHECK CONFLICTS BY ROW TIMESTAMP
COLUMN ConflictResTimeStamp
REPORT TO '/sn/sps/HDF620/datamodel/tt41dataConflict.rpt'
MASTER tt41data ON "TBMAS10df2-ttrep"
SUBSCRIBER tt41data ON "TBMAS9df1-ttrep"
RETURN RECEIPT BY REQUEST;
On this subject moving from 6.0.x to 7.0.x there has been some changes I would like to better understand.
6.0.x reported in the documentation for Unix systems:
If a host contains multiple network interfaces (with different IP addresses),
TimesTen replication tries to connect to the IP addresses in the same order as
returned by the gethostbyname call. It will try to connect using the first address;
if a connection cannot be established, it tries the remaining addresses in order
until a connection is established.
Now On Solaris I don't know how to let gethostbyname return more than one interface (the documention notes at this point:
If you have multiple network interface cards (NICs), be sure that “multi
on” is specified in the /etc/host.conf file. Otherwise, gethostbyname will not
return multiple addresses).
But I understand this could be valid for Linux based systems not for Solaris.
Now if I properly understand the above, how was the 6.0.x able to realize the first interface in the list (using the same -ttrep hostname) was down and use the other, if gethostbyname was reporting only a single entry ?
Once upgraded to 7.0.x we realized the ADD ROUTE option was added to teach TT how to use different interfaces associated to the same hostname. In our environment we did not include this clause, but still the replication was working fine regardless of which interface we were bringing down.
My both questions in the end lead to the same doubt on which is the algorithm used by TT to reach the replicated node w.r.t. entries in the /etc/hosts.
Looking at the nodes I can see that by default both routes are being used:
TBMAS10df2:/-# netstat -an|grep "151.98.227."
151.98.225.104.45312 151.98.227.4.14000 1049792 0 1049800 0 ESTABLISHED

151.98.226.5.44949 151.98.226.4.14005 1049792 0 1049800 0 ESTABLISHED
Tried to trace with ttTraceMon but once I brought down one of the interfaces did not see any reaction on either node, if you have some info it would be really appreciated !
Cheers,
Mike

Hi Chris,
Thanks for the reply, I have few more queries on this.
1.Using the ROUTE CLAUSE we can use multiple IPs using priority level set, so that if highest priority level set in thr ROUTE clause for the IP is not active it will fall back to the next level priority 2 set IP. But cant we use ROUTE clause to use the multiple route IPs for replication simultaneously?
2. can we execute multiple schema for the same DSN and replication scheme but with different replication route IPs?
for example:
At present on my system, I have a replication scheme running for a specific DSN with stand alone Master-Subscriber mechanism, with a specific route IP through VLAN-xxx for replication.
Now I want to create and start another replication scheme for the same DSN and replication mechanism with a different VLAN-yyy route IP to be used for replication in parallel to the existing replication scheme. without making any changes to the pre-existing replication scheme.
for the above scenarios, will there be any specific changes respective to the different replication schema mechanism ie., Active Standby and Standalone Master Subscriber mechanism etc.,
If so what are the steps. like how we need to change the existing schema?
Thanks In advance.

Replication of customers from R/3 to CRM

Hi everybody,
After completion of Initial Download of data from R/3 to CRM ,the customers replicate crm.
But my doubt is once we do initial download then the customers which are in R/3 in bulk are replicated to R/3.But there are few customers which are still replicated from R/3 daily.
So I want to know the reason for this replication even though after the initial download is completed.
please help me.
regards

Hi pankaj,
Step 1:After completing Initial Download tranfer of data takes place from R/3 to CRM system in the form of Customers or employess.
Bulk data will be flown in the first step.
I f there are any errors ,we solve the errors and replicate them manually by using CRMM_BUPA_map.
Step2:There are few customers which are created daily in SAP SD or R/3 and these customers are transfered from R/3 to CRM .
So my question is Is this b'cos of Delta Download or Bcoz of some other Reason.
If so "Is there any specific name for this.

Replication error BP from CRM to R/3 - "Fill in all required entry Fields"

Dear Folks
I have maintained all steps mentioned in building block - C03. I have maintained separate account group approach. Made sure that number ranges are in sync in both the systems. Particularly in PIDE, mapping classification Consumer-Org 'A' to 'ZZ01' (Copy of 0001).
      I changed all required entry to optional entry in my 'ZZ01' field status using OVT0.
       But when i replicate using R3AS, i get an error 'Fill in all required entry Fields" - Error in receiving system (i.e R/3).
       I tried manually creating customer in R/3 with the account group ZZ01. Surprisingly it does not allows me to save unless i give the reconcillation account entry, even though it is not a required field.
   Please let me know for further details and Please help me to resolve this error. I am in real urgency.
Thanks

Hi Karunakaran
        Your reply answered my question of creating customer with no 'recon' a/c required entry. Thanks awarded 2 points.
          My replication error is still hanging around. I found that It has no bearing on the 'Reconcillation A/c' required entry.
          Some other field is still restricting my BP Role- Consumer:Organization to replicate. The error still showing as "required fields are not entered in R/3", even after suppressing "Reconcillation Account".
       I think my reference customer master i created in R/3 using VD07 is not assigned in case of the account group Consumer:Organization.
   But i don't know how to verify my doubts and get rid of this error.
Please help, in great urgency.

Doubts in bw

hi gurus
i had very litle doubts in bw can u plz clarify me and these r question are asked in some intereview.
1) what is difference between exception and condition
2)if u create infoobjects what r the settin we r goin to do ?
3)what is difference between extraction and replication?
4)what is use of reportin' agent?
5)what is the use of routines and when and where we use routines?
6)In what Scenario we use formule in query ? give me example?
7)what is difference between customer exits and sap exits?

Hi Raju,
1) what is difference between exception and condition
-->> Conditions: You can formulate conditions to make data analysis more efficient. In the results area of the query, the data is filtered according to the conditions so that only the part of the results area that you are interested in is displayed.
http://help.sap.com/saphelp_nw04/helpdata/en/43/b57138c1afbd20e10000009b38f889/content.htm
Exceptions: In exception reporting you select and highlight objects that are in some way different or critical. Results that fall outside a set of predetermined threshold values (exceptions) are highlighted in color. This enables you to identify immediately any results that deviate from the expected results.
Exception reporting allows you to determine the objects that are critical for a query, both online, and in background processing.

5)what is the use of routines and when and where we use routines?
--> To calculate values(like revenue = value * qty) and to meet customer specific requirements.
6)In what Scenario we use formule in query ? give me example?
--> To calculate/Derive some values.
7)what is difference between customer exits and sap exits?
-->> The SAP Exit processing type is contained in variables delivered by SAP BW within the Business Content framework.
If you need to use a processing type other than manual entry / default value, replacement path, SAP exit, or authorization, then a customer exit gives you the option of setting up a processing type for variables, tailor-made to your specific needs.
http://help.sap.com/saphelp_nw04/helpdata/en/f1/0a5702e09411d2acb90000e829fbfe/content.htm

Synchronous Storage Replication Process

Hi,
I have a question regarding storage replication for synchronous mode. If I describe the process in detail having twin Data Centers called DC-A and DC-B we have:
1- The server in DC-A writes to the DC-A disk.
2- Before the server in DC-A receives an ACK from the DC-A disk, this data is replicated to the other DC disk, DC-B Disk.
3- To replicate the data to the other DC we will first ask to the other DC before passing through the DCI “are you ready to receive”?
4- We will get the approval from DC-B that is ready
5- Then DC-A will send the data through the DCI to arrive to DC-B.
6- DC-B disk receives de data and then DC-B disk must send an ACK to DC-A Disk
7- Once the ACK is received at DC-A disk, DC-A disk will then send the ACK to the server in DC-A which originated the write action.
My question is if step 3 and 4 sometimes are counted and sometimes not. I should counted or not? This decision is important for me because it affects by a factor of 2 the distance between the twin DCs.
Thank you very much for the help.
Regards,
J

Hi,
just to add more information. My doubt comes from the 2 Cisco live sessions about DCI.
On this session it says that we must count 4 times the traffic passing through the DCI in order to know the DCI Distance:
https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=6623&backBtn=true
On this other session it says that we must count only 2 times:
https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=7775&backBtn=true
Who is right then? because the impact is huge.
Thank you.

Sybase replication server on HA / DR

Hi Experts,
We are in the process of setting up DR environment for Sybase ASE using replication server. The primary site has an HA configured.
My doubt is when we need to install replication server at standby site, what host needs to be specified as the "primary system hostname" - The hostname of CI or the DB server.
Additionally, do we need to install replication server on both nodes of HA cluster? and how would the DR agent configuration work in case of DB failover to the CI node?
Unfortunately, there is very little documentation available online on how to setup the DR environment, apart from SAP note 1891560
Would appreciate your invaluable inputs on this.
Thanks in anticipation.
Regards,
Varun

Hi Varun,
Sorry - I don't have any experience with the IBM solution. So I have comments, but not a solution.
The HADR Solution will work well in HA / cluster systems where the IP address is dynamically re-assigned to the active node. This allows the server configurations to point to just 'one' IP address and the cluster software (examples: MS Cluster, Veritas, HP Service Guard) assigns that IP to which ever node is active.
Using the IBM solution, (based on a quick Google search) it appears we rely on Open Server HA capability to include both addresses in the interfaces file under a single Server name, so that both address can be attempted when making a connection.
Unfortunately, the configurations created by the DR Agent do not support this type of configuration using Interfaces files. Most server address are assigned a single IP address, and most address are assigned directly (not pointing to an Interfaces file entry).
As an example, when the HADR nodes are configured in ASE, you define the other nodes in the HADR group with a command like the following:
sp_hadr_admin addserver, <node_name>,<server_name>
To use a interfaces file name for the server name, the command might look like:
sp_hadr_admin addserver, 'D01_Site1', 'D01'
But the configurations created by the DR Agent use a host:port syntax instead of an interfaces file server name, like:
sp_hadr_admin addserver, 'D01_Site1', 'host1.my.domain.corp:5001'
The point I am trying to make is that even if we edit the interfaces files to use the additional HA addresses, other configurations like the one above would need to be discovered and changed as well.
Unfortunately, even if all this reconfiguration work is accomplished successfully, the DR Agent itself does not use interfaces files and has no support for specifying an alternate HA address. And I am not aware of any workaround for that limitation.
In summary, I think that short answer is that we don't have HADR support using DR Agent for HA environments without a dynamic IP address. It might be possible to manually reconfigure some of it, but without support in the DR Agent itself, you would be missing failover and monitoring support the DR Agent provides.
Sorry that I do not have a more encouraging answer.

Stephen

Lock in Advanced Replication

Hi everyone!
I'm studying the theory of replication on manuals found on OTN, and I can't answer myself to a question: what happens when I lock one or more table in a site? The lock propagates to all copies of the table across other sites?
Thank you for resolv my doubt :)
Bye!

How are you locking the table?

Windows 2012 - SYSVOL replication and NETLOGON share

After reading 100 tons of articles and links i decided to open this thread.
I know today is 1st of april, but unfortunately for me this is not a joke.
given:
two 2003 DC's - physical servers
two 2008 DC's - VM's on ESX 5.1 hosts
two 2012 DC's - VM's on ESX 5.5 hosts
domian fucntional level 2003
situation:
we plan to decom the 2003's.
The 2008 DC's are in place since a while and working ok.
We plan to upgrade to 2012 and here it is where the trouble starts.
Firstly, I couldn't, by any means, to promote 2012 as DC's until i moved all the FSMO roles from the 2003 DC's to the 2008 DC's.
After lots of work with the network team we made all the right connections opened the firewalls, made the DCDIAG and DNS tests and the only problem reported are the SYSVOL replication and NETLOGON share.
I tried all the tools out there to check the replication and the last one is Microsoft's AdRplstatus Tool which made me think that either Microsoft makes fun of me, either i'm the dumbest windows admin on this planet.
This tool reports that there are NO ERRORS in replicating SYSVOL, but when i run the command 'net share' the 'domain.com\sysvol\scripts' is not there. Further more checking, i try to access '\\domain.com\sysvol' - directory under which i must find the 'policies'
and 'scripts' folders and, Sysvol is empty - obviously these are present when i do this check from the 2008 DC's or 2003 DC's.
Is there a known issue for these problems regarding 2012 and ESX 5.5 ? - still, i doubt it.

The PTR record query for 1.0.0.127 is still there but i will change it manually, my DNS is set as primary to point to the server itself by it's IP and not 127.0.0.1.
still, that DNS server with that error is a linux DNS, but all my DC's have DNS role on and fully replicating and working, including the 2012's.

To perform non-authoritative restore of sysvol, you set the Burflag value & system will automatically tries to sync contents of sysvol with its replicating partner DC. Its not mandatory to select any particular DC for sysvol replication becasue in a
same domain, all DC's shares the same sysvol content.
Sometime, if initialization of FRS doesn't start, you have to follow the below article. Its also applicable to windows 2008 even as long as your using FRS for replication.
http://support.microsoft.com/kb/290762/en-us
To force the replication of sysvol using cmdline, refer below link.
http://blogs.technet.com/b/justinturner/archive/2007/04/27/quick-tip-force-frs-replication.aspx
Its better to find out what went wrong with the overall AD domain infra that sysvol has not been able to contact its partner for sysvol replication using depth assessment of the domain. It can be the network,firewall,antivirus or in-built firewall port issues
which might have broken sysvol replication.
