Mapping question - concat two nodes

hi all,
i need to map a node with many occurrencies to a node with only one ocurrency, and i need to concat all the values from the source node into the target node.
example:
<delivery> 1..unbounded --> <data> 0..1
<delivery> "this is "
<delivery> "an example"
result
<data> "this is an example"
does anybody know how can i solve this qestion?
thanks in advanced.
regards, Fabian

Hi,
Go for UDF...
pass the source data as queue input to the UDF(i.e array)..in that udf loop over the source input and do concat inside the loop and pass the final result to the target element...
string target = "";
for(int i =0 ;i<input.length;i++)
target = target + input<i>;
if there are multiple contexts in this then need to handle the same

How to draw a line on ADF page between two nodes for mapping.

Hi everyone,
Does anyone have a solution that how can I wiring two points by drawing a line on ADF pages.
My scenario is user want to do a mapping between two xml files. We will build an ADF faces page. This page have two parts, left part contains one tree(base on the source xml), right part is the destination tree(target xml). User can drag an node from left and drop to right. Meantime, a line will be created to connect two node, it would be perfect that when user scroll down the page, or extend the tree node, the line between source and target will be remain connection two node.
Does anyone have a solution for this, thanks in advance.

Need to create two nodes based on one condition in message mapping.

Hi Experts,
In my mapping I have two different nodes. If my condition is true then only one node should be created otherwise both the nodes should be created.
requirement is I need to print. one header before first item record and after every 200 item records.
i.e I need to create header node if (item recordno) is 1 or (item recordno % 200) is 1. I have tried using this condition. But Iam getting all the header records( 3 headers for 600 items) in sequece and then all item records (600).
i want 1 header then 200 items , then again header followed by 200 items. so on.
Can any body help.
Thanks&Regards,
REYAZ HUSSAIN

Hi REYAZ HUSSAIN,
as graphical mapping is "target field mapping" this is not possible. The parser for graphical mapping traverses the taget message from the first element to the last!
You need another kind (ABAP, XSLT, JAVA) of mapping.

Two node installation with 2 concurrent managers..

Need your help. I have 12.1.1 Two node installation on Linux 5.9 with 64 bit.
Linux2- Database server + Concurrent manager
Linux1- Apps Node
Port - 8002 (port pool -2)
on my app node - linux1, I have 2 directories <SID>_linux1 and <SID>_linux2. First one is for primary apps node and second one is for 2nd concurrent manager. It is a shared directory structure. I have 2 questions:
1) If I run the autoconfig on Linux1, I can run all the services and connect to apache. However, If I run the autconfig on linux2, I will not be able to connect to web server (for a short time request will be sent to Linux1 and then it gets forwarded to Linux2 - even though Linux2 is not app server).
2) How do I run the second concurrent manager on LInux2? After I run the 2 concurrent manager, how do I test both concurrent managers are working?
Your help is much appreciated.

Hi Hussein,
Thank you for the info. I was wondering whether the Linux2 concurrent manager was installed correctly or not. I went to xml file and found these entries and it made me think, it didn't install correctly because only concurrent manager should have been yes and the rest should be no. Isn't it? If it is wrong, how do I correct this?

How does Dynamic Quorum work for a two Node DAG

Hi All,
I have a two node DAG with a FS witness server. One of the node is 'down' (I have kept it like that), cluster has quorum and all services are online.
What I'm trying to understand is if a node's State=Down, isn't the Dynamic Quorum Group Manager suppose to trigger and set the DynamicWeight to '0' for that server.
In my case its not doing so, please let me know if this the way it is, or something is not quite right and I need to fix it.
Troubleshooting info below:
PS C:\Windows\system32> Get-ClusterNode | ft name, dynamicweight, state, nodeweight,id -AutoSize
Name DynamicWeight State NodeWeight Id
exch1 1 Down 1 1
exch2 1 Up 1 2
PS C:\Windows\system32> (Get-Cluster).WitnessDynamicWeight
1
PS C:\Windows\system32> Get-ClusterResource
Name State OwnerGroup ResourceType
Cluster IP Address Online Cluster Group IP Address
Cluster Name Online Cluster Group Network Name
File Share Witness (\\fs1... Online Cluster Group File Share Witness
(Validation test)
Validate Quorum Configuration
Description: Validate
that the current quorum configuration is optimal for the cluster.
Validating cluster quorum settings.
Witness Type: File Share Witness
Witness Resource: \\fs1.contoso.com\dag1.contoso.com
Cluster managed voting: Enabled

exch1
Down
1
1
exch2
Up

1
This quorum model will be able to sustain failures of 1 node(s) if the file share witness remains available
and 0 node(s) when the file share witness goes offline or fails.
This quorum configuration can be changed using the Configure Cluster Quorum wizard. This wizard can be started from the Failover
Cluster Manager console by selecting the cluster name in the left hand pane, then in the right "actions" pane selecting "More Actions..." and then selecting "Configure Cluster Quorum Settings...".
When all servers were up
node/2+1 = 2/2+1=2 required for quorum and we have 3 votes
When 1 server gone 1/2+1=1 quorum should recalculate to this. But its still considering 3 votes out of 1down server+1up server+1witness. Ideally I should be able to loose the witness too aftersome time and still maintain quorum(unlike what
the validation test is saying).

Hi Simon,
Thanks for your response.
I have done some study, testing and what I figured out is this.
Split brain syndrome is prevented by always requiring a majority of the DAG members (and in the case of DAGs with an even number of member, the DAG witness server) to be available and interacting for the DAG to be operational.
All DAGs with an even number of members must use a witness server.
Hence a 3 node cluster behaves differently than a 2 node. Exchange 2013 DAG kind of forces you to have a witness server always.
You can specify only a name for the DAG and leave the Witness server and
Witness directory fields empty. In this scenario, the task will search for a Client Access server that doesn't have the Mailbox server role installed. It will automatically create the default witness directory and share on that Client Access
server and configure the DAG to use that server as its witness server.
You can
'overridde the quorum configuration using Windows2012 Failover Cluster Manager', however using it to modify a DAG is not recommended.
If you open Failover Cluster Manager in Administrative Tools, you’ll find the Database Availability Group (DAG), cluster networks and so on. Don’t try to manage the DAG
using the Failover Cluster Manager, as this isn’t supported. The Exchange Management Console (EMC) or the Exchange Management Shell (EMS) are the only ways to manage the DAG.
Unless you’re doing a DC switchover and/or being assisted by Microsoft Support services (premier)
Now back to the point:
When we are left with 2 nodes and 1 witness server for Exchange HA. The Dynamic Quorum functionality kind of stops dealing with it. As 2nodes/2+1=2votes this means we need to have atleast 2 votes to have quorum.
So if we assume Dynamic Quorum triggers and removes 2 votes, 1 from Witness and 1 from nodeB.
Then the new formula we have is 1node/2+1=1vote which would mean this would allow us to loose both the witness and the nodeB. And nodeA will be the last man standing as in this
article.
However having this scenario in a two node cluster brings in the split-brain problem. As if there is a full disconnect of nodeA site and nodeB+Witness can talk, they form quorum , nodeB mounts the database. Which is undesirable.
Hence Dynamic Quorum keeps the votes to 3 in a 2nodes+1witness scenario contrary to what is expected and in turn keeps everything running fine till we have 2votes available, just like 2010,Windows2008 days.

Mutliple serveres in a two node RAC

hello friends m i newbie in RAC and i have 7 servers in my company 4 are for oracle database used for different purposes having same instance name on each of them and 3 are for application servers used for different purposes having same instance name and i want to use two node RAC for all of them now my question is
1) can i use all the 7 servers (4 database and 3 application) together in a two node RAC?
2) in RAC can i have different instances having same name?
thanx in advance

That is how Oracle scales.
Oracle does not scale the converse way - running multiple databases on a single server.
1) can i use all the 7 servers (4 database and 3 application) together in a two node RAC?That depends entirely on whether the 2 severs have the capacity to deal with the processing load currently handled by the database servers.
Also note that in Oracle the terms "+database+" and "+schema+" differ from what are used by some other RDBMS products.
An Oracle database is a physical entity. An Oracle schema is a (amongst other things) a logical database. So a single physical Oracle database can contain 1000's of logical databases - and these logical databases can be physically separated from one another (via tablespaces), can have different rights, can have different resource profiles, etc.
Each RAC node is part of a shared everything cluster - meaning that the entire physical database is available on each and every RAC node.
On RAC, you can do what is called application partitioning. You can for example configure HR clients to make use of the HR logical database (schema) on RAC node 1. RAC node 3 is for example used for the Data Mart application and node 2 handles the customer billing clients.
In other words, you partition your applications across RAC nodes.
2) in RAC can i have different instances having same name? The instance name is a physical name and should very seldom be explicitly used. Your physical RAC database's SID may be PROD. Your 4 RAC instances, one on each server, will have SIDs PROD1 to PROD4.
But you should instead create database services and have clients connect (via the RAC's SCAN/Single Client Access Name) to a specific service.
Bottom line to keep in mind - RAC is Oracle's answer to scalability. And RAC is multiple servers and a single database. Doing the converse and running multiple database on a single server (RAC or no RAC), very seldom makes any technical sense. It almost always will reduce both performance and scalability.

Single JVM, two nodes, separate override files configuration?

This question might have surfaced before in the forums but even after going through several posts I couldn't get a decent understanding on how this works. Here is my question...
I wanna bring up two coherence nodes in a single JVM, both independent and unrelated to each other. These two nodes have different cache-config xml files, and also override files. My question is how do I configure these nodes such that they work with two separate override files. I don't wanna use -Dtangosol.coherence.override because my doing this, this system property applies to both the nodes so I can't keep the override xml files separate.
So, what is best way to accomplish this such a way that the nodes don't collide with each other by using a common override files?
I hope I am clear.
Thank you.

Hi,
Both the solution I posted and Jon's solution rely on a ClassLoader to isolate the Coherence nodes within the JVM. We do not use this in Production but we do use it as part of our build process and run over 18,000 test cases with a single JVM cluster, so in that respect it works well. I think if you used it in Production you would need to have done a lot of testing to make sure that there are no very subtle issues that might come back to bite you later.
The reason doing what you want is difficult is because Coherence uses a number of singletons at runtime - for example the Cluster instance, and without using a class loader it is difficult to have more than one of these. Coherence also uses a lot of System properties to override configuration values so these may need to be isolated too.
Finally using a class loader would make if difficult for your application code to interact with the two isolated nodes inside the single JVM.
It might be better if you told us why you think you need to run two nodes in a single JVM - what requirement are you trying to meet? There might be a much more sensible solution to your requirements. As NJ has suggested using Extend might be one solution but without knowing more about what you want to do I couldn't say for sure.
If you don't know what Extend is then read the documentation - The Client Guide covers Extend http://docs.oracle.com/cd/E24290_01/coh.371/e22839/toc.htm and the rest of the documentation is here http://docs.oracle.com/cd/E24290_01/index.htm

OVD question -- Hiding selected nodes

Hi,
This is what my OVD DIT looks like:
Join View Adapter:
Primary Adapter: OID
Join Adapter: AD
The resulting DIT looks like this:
dc=company,dc=com
- cn=OracleContext
- cn=Calendar Server
- cn=Users
- cn=Groups
- ou=Oblix
I would like to expose only cn=Users and cn=Groups in my OVD. How do I hide the remaining nodes? I tried DN Matching, but it blocks all the children nodes.
The other option is to create a Local Store Adapter for dc=company,dc=com and then create two nodes:
- Join View Adapter for ou=Users
- Join View Adapter for ou=Groups
Is it safe to use a Local Store Adapter in a production environment, if it contains no data? I basically need this for an OAM deployment.
Thanks.

hello,
i think, from OVD view you want to allow only the users node & groups node and not the OracleContext,Calender, oblix nodes. if i am correct, then you might done your adapter configuration in this approach:
1. create the local store adapter as:
cn=users,dc=company,dc=com (if u want ou instead of cn, just define ou mapping for the users node)
cn=groups,dc=company,dc=com
2. create 2 adapters with the following parameters:
a) remote is: cn=users,dc=company,dc=com
root Base: cn=users,dc=company,dc=com
b) remote is: cn=groups,dc=company,dc=com
root base: cn=groups,dc=company,dc=com
in this approach you definately get the users, group nodes and its children nodes. ofcourse, if you want to do object mappings on any specific entity like user node you can extend in the adapter configuration.
Also, it won't be any issue by using the local store adapter in production also. you will be using this local store adapter only for mapping puprose and for storing the data i believe, you might do any operation onthe user nodes under user/group node but not on user/group node right!

BizTalk HIPAA EDI multi-input map doesn't generate node

I have a BizTalk HIPAA solution that needs to merge an 837 claim schema with some data from our system. We're doing this with a map that has two input schemas, as shown here:
(I've greatly simplified the schemas for testing purposes).
In the first input message, if IsRepriced = 1, I want to use our values for HCP_01, HCP_02, and HCP_03. If it's 0, use the values in the second message (the original 837 claim). The functoids shown work fine as long as the original 837 claim actually contains
the HCP node (segment), but if it's not there I'm unable to generate one from our data.
Replacing these with a scripting functoid using some if-then-else C# code has the same effect.
So, is there a way to do this using functoids, or do I need to resort to XSLT? Unfortunately I know next to nothing about XSLT, so that's going to be difficult...
Thanks!

I really, really hope someone else has a super-secret technique to solve this but....
I frequently hit a brick wall with with the if missing-else paradign in a Map. Sometimes Looping Functioids do the trick, sometimes not. Sometimes a carefully placed Logical Existence -> Not works, sometimes no.
It's mostly because if one of the source Records is minOccurs=0, the Mapper will wrap everything in a for-each. Since the Element doesn't exist, the code never gets executed.
I'd say >50%, I resort to inline Xslt because at some point, it becomes cleaner than a page of mostly duplicate Functoid groups.
However, I'd bet the Xslt won't turn out as difficult a proposition as you think. The Mapper can do most of the work for you. You can build the bulk of the Map using Functoids, then just copy the resulting Xslt. You will have to modify
for some things, like namespaces.

Two node - Two site Active/Active DAG Configuration

Information
Both sites exist in a single AD domain
Site A
1 Exchange 2013 multi-role server (CAS + MBX)
Server will contain mailboxes for individuals who work in Site A
Server will contain database copies of databases in Site B
Site B
1 Exchange 2013 multi-role server (CAS + MBX)
Server will contain mailboxes for individuals who work in Site B
Server will contain database copies of databases in Site A
Goal
To create a configuration where users who work in Site A have their mailboxes active in Site A and users who work in Site B have their mailboxes active in Site B.
Questions
Since this DAG has an even number of members, where do I place the witness server? Do I need two witness servers, one in each site?
It seems to me as long as both sites can still communicate, I only need one witness server to maintain quorum.
To my current understanding, if Site A has a witness server, and Site A looses its WAN connection, Site B's databases are going to go offline because it has lost quorum.
I'm assuming if I placed a witness server in each site, and one of the sites lost its WAN connection, then I'd be placed in a split-brain scenario as both sites would still think it had quorum. Is this accurate?
The company has given me a limited budget hence the reason for only having two exchange servers in this setup. Is my only recourse to have four nodes (two nodes per DAG) in this active\active scenario? If the company says they absolutely cannot spend money
on two more servers, could I use the current setup in an active\passive configuration?
Thanks!

You would need to place the File Share Witness in a 3rd datacenter for automatic failover, otherwise depending which DC the FSW is ( and you can only have one FSW per DAG active a time), then in case of a WAN or DC failure, the databases will be active in
the DC that has quorum.
If the FSW is in Site A and Site A goes down, then quorum is lost and Site B will need to be manually swithed over using this procedure:
http://technet.microsoft.com/en-us/library/dd351049(v=exchg.150).aspx
To be truly active/active in both DCs, then you would need to 2 DAGs with each respective FSW in each DC that has the preferred user base.

CRMXIF_REL_SAVE_M01 - Mapping Question

Hello All,
I have a mapping question, hope some one can answer my question. Please see the link first and the see my question
http://www.flickr.com/photos/8764045@N06/4265246260/sizes/o/
I'm mapping the CRM IDOC to the JDBC Call. I have small problem here. All the target fields are Mandatory 1..1 .
I will explain with an example:
I have field from source E102BUS_EI_STRUC_TEL_DATA/COUNTRY mapped to target field.
I used Map With Default so that even if the values are not there frm the source the target field will be mapped with blank.
But the problem is the parent node for E102BUS_EI_STRUC_TEL_DATA is E102BUS_EI_BUPA_TELEPHONE is 0.999999 , so sometimes that segment is not coming. In this case Map with Default won't work. Map with Default willl work only if the Parent node is present.
If you ask me to do Exists node function on E102BUS_EI_BUPA_TELEPHONE and then apply Map with Default, then even this won't work.
Apologize if I confused you guys. Please let me know if you need more clarification.
Thanks!
Raj.

Hi Raj,
Try to do a mapping like this
E102BUS_EI_STRUC_TEL_DATA(context E102S_EI_BUPA_TELEPHONE_CON)--mapwithdefault-->then
E102BUS_EI_BUPA_TELEPHONE-->exists------------------------------------------------------------------>if---->splitbyValue
let us say this output (the output of splitbyvalue) as 'VALUE'
VALUE-----------------------------------------------> then
VALUE|-->count--->greater----------------------->if----->targetField
Constant(0)----> Constant(blank)-->else

Is it possible to create a two node cluster with SQL server 2012 STD on node1 and SQL Server 2008 ENT on node2 on a Windows server 2012?

Hi All,
Is it possible to create a two node cluster with SQL server 2012 STD on node1 and SQL Server 2008 ENT on node2 on a Windows server 2012?
aa

I think you are confused with the way cluster is installed. Installing SQL on cluster is a two step process. On first node you create a new SQL cluster and on second node you need "AddNode" action.
Same edition media has to be used in above two operation.
you can install two separate instances with one enterprise and one standard.

Questions about multiple nodes and licenses

Nico, What would be the right forum to ask the licensing questions i stated above? Jimit

I can't and won't discuss license issues, but for the last question (mixing nodes with different operating systems) there's a fairly easy answer why this can lead to all sorts of trouble.Windows and Linux/Unix usually work in different code pages, making it hard to interchange flat files.Text lines in Windows flat files are usually terminated by the two characters Carriage Return followed by Line Feed (0x0D followed by 0x0A) whereas under Linux/Unix text lines are always terminated by Line Feed characters (0x0a) only. Not all Windows and Linux/Unix programs can handle this difference without trouble.Very often Windows and Linux/Unix machines run with difference 8-bit code pages for the nodes themselves. This means that all sorts of diacritics (such as German Umlaute ä, ö, ü, ß) may be processed by programs on both platforms in different ways.Shell scripts and batch files resp. all sorts of operating system commands are very much incompatible between these systems, making it almost impossible (ok, just extremely difficult) to write scripts running on both system worlds.Last not least Integration Services in a server grid must be of the same operating system and run in the same code page, meaning that these two nodes will never be able to be part of the same server grid. That's just what came to my mind within a few seconds of thinking. Regards,Nico

CONVERTING TWO NODE RAC ON WINDOWS TO SINGLE INSTANCE

I got question about a two node RAC on Windows.
One of our vendors is hosting our oracle enviroment and we are planning to bring in the datacenter in house and manage it ourselves.
Current they have a two node RACon windows
The new enviroment we are building here , we want to get rid of RAC and bring it back to a single instance environment.
How do i approach this?
1. My first option was to create a new database server and do the export dp from one of the node and import to the new single instance enviroment.
My conncern is can you do export from RAC database and import it to a non RAC enviroment?
2. My second option is to delete one node on the two node RAC and then do export dump or cold backup and copy the database files and necessary config files.
let me know how i can approach this.....

Okay guys after digging aroung i found the following approach.....
Cloning Oracle 10gR2 from RAC Environment to Single Instance Environment will raise the following error
ORA-29702: Error occurred in Cluster Group Service Operation.
The new instance is looking for CRS on new single instance non RAC environment.
For UNIX platform follow the following steps:
- Shutdown the instance which is cloned to non RAC.
- Shutdown all the listeners.
- Relink Oracle executable with rac_off option.
$ make -f ins_rdbms.mk rac_off
$ make -f ins_rdbms.mk ioracle
- Remove all the parameters from init.ora which points to second instance
and it is on other node.
- Remove cluster_database parameter
- Remove undo_tablespace parameter which points to second instance
For Windows Platform follow the following steps:
- Shutdown the instance which is cloned to non RAC.
- Shutdown all the listeners.
- Rename following file in %ORACLE_HOME%/bin directory: orarac10.dll to orarac10.dll.bak
Give me your thoughts, there is nothing on Metalink....

Could you tell me if it would be supported to pair a two node enterprise edition front end pool inc mirror sql with a one node enterprise edition front end pool inc single sql?

Hi all,
Could anyone tell me if it would be supported to pair a two node enterprise edition front end pool inc mirror sql with a one node enterprise edition front end pool inc single sql?
MUCH THANKS.

The answer from TechNet found at http://technet.microsoft.com/en-us/library/jj204697.aspx Is, and I quote:-
Enterprise Edition pools can be paired only with other Enterprise Edition pools. Similarly, Standard Edition pools can be paired only with other Standard Edition pools.
Also, "Neither Topology Builder nor topology validation will prohibit pairing two pools in a way that does not follow
these recommendations. For example, Topology Builder allows you to pair an Enterprise Edition pool with a Standard Edition pool.
However, these types of pairings are not supported."
