Oracle Metadata Services (MDS) repository Oracle SOA-MDS / BPM-MDS 11g

MDS  - Matadata Service.

Why MDS ?

 From Development to Production moving complete code to server from Jdveloper and maintain complete code base version .

Two types of MDS :

     

  1. File system MDS :

                             

 Advantage :  File system MDS are useful in terms of maintain complete xsd,wsdl,xml,etc  in same system .so when ever developers want to change any elements in xsd,wsdl,xml,etc are very frequently.

If I use file system MDS during development time  , then how weblogic server will understand  the local file system reference during run time ???

simple create jar ,then  convert into soa-bundle and deploy to the server. so in adf-config.xml file system MDS URL are not hard coded . I would suggest to use file system MDS.

Dis-advantage :   Multiple developers not able to use during development .

 2. Database MDS :

Advantage :  During development time multiple developers can share the same wsdl,xml,xsd  from Database MDS.

Dis-advantage :  MDS URL hard code in adf-config.xml ,when we generate configuration plan. those MDS URL are not  a part of any reference or as a service.

Example :  Business Analysist  create BPM template and those templates are saved in MDS repository . Developer job to check out the complete template  code and develop the process .

I listed few usage of MDS .

Step to create File system MDS Connection :

 create folder name apps in below location  :

              Jdeveloper11.6\jdeveloper\integration\seed

apps --> place xsd, wsdl, xml , etc ..

Resource Palette - > IDE Connection - > SOA - MDS 

now  make reference to  file system MDS in adf-config.xml . 

ApplicationResource - > Descriptors - > ADF  META-INF - > adf-config.xml

as I mentioned earlier  during development time apps folder reference in local system , but when the same deployed in weblogic server. Reference inside adf-config.xml automatically resolve during runtime.

Step to create SOA_Bundle ( MDS weblogic server ) and Database MDS :
