Things to remember when exporting/importing metadata into MDS in Weblogic cluster

Hi,

I wasted a few hours (and i hope you will not) to use WLST command to import metadata into WebCenter spaces PS2 application in a cluster environment.

The weblogic server topology was as follows, each of them running 2 managed servers for WebCenter.

Note: Server 1 and 2 were different physical machines

• Server1 had WLS_Spaces1 and WLS_Spaces3
• Server2 had WLS_Spaces2 and WLS_Spaces4

Problem:

I tried to export meta-data using following command from MDS after connecting to AdminServer, replaced the page in export directory and import back.

   1: exportMetadata('webcenter','WLS_Spaces1','/home/oracle/mds','/oracle/**/Login.jspx')

   2: importMetadata('webcenter','WLS_Spaces1','/home/oracle/mds','/oracle/**/Login.jspx') 

   3:  

   4: exportMetadata('webcenter','WLS_Spaces2','/home/oracle/mds','/oracle/**/Login.jspx')

   5: importMetadata('webcenter','WLS_Spaces2','/home/oracle/mds','/oracle/**/Login.jspx') 

   6:  

   7: exportMetadata('webcenter','WLS_Spaces3','/home/oracle/mds','/oracle/**/Login.jspx')

   8: importMetadata('webcenter','WLS_Spaces3','/home/oracle/mds','/oracle/**/Login.jspx') 

   9:  

  10: exportMetadata('webcenter','WLS_Spaces4','/home/oracle/mds','/oracle/**/Login.jspx')

  11: importMetadata('webcenter','WLS_Spaces4','/home/oracle/mds','/oracle/**/Login.jspx') 

I received a message that 1 document has imported into MDS successfully, but somehow my changes were not visible.

Lesson learned:

When you export the documents from MDS in a cluster it creates a export directories (in my case /home/oracle/mds) on the same machine where managed server is running i.e. Server1 and Server2 machines.

So, my import statement was importing the same export page which was already in the repository.

Solution:

For easy understanding i created a separate directories for all managed servers and replaced the page on both machines then imported into MDS.

Here is the complete command list.

   1: exportMetadata('webcenter','WLS_Spaces1','/home/oracle/mds1','/oracle/**/Login.jspx')

   2: importMetadata(application='webcenter',server='WLS_Spaces1',fromLocation='/home/oracle/mds1',docs='/oracle/**/Login.jspx') 

   3:  

   4: exportMetadata('webcenter','WLS_Spaces2','/home/oracle/mds2','/oracle/**/Login.jspx')

   5: importMetadata(application='webcenter',server='WLS_Spaces2',fromLocation='/home/oracle/mds2',docs='/oracle/**/Login.jspx') 

   6:  

   7: exportMetadata('webcenter','WLS_Spaces3','/home/oracle/mds3','/oracle/**/Login.jspx')

   8: importMetadata(application='webcenter',server='WLS_Spaces3',fromLocation='/home/oracle/mds3',docs='/oracle/**/Login.jspx') 

   9:  

  10: exportMetadata('webcenter','WLS_Spaces4','/home/oracle/mds4','/oracle/**/Login.jspx')

  11: importMetadata(application='webcenter',server='WLS_Spaces4',fromLocation='/home/oracle/mds4',docs='/oracle/**/Login.jspx') 

Hope you find it useful,
