Looking at "\SOI\wso2registry\repository\conf\registry.xml, user-mgt.xml" the connection string was incorrect, due to this SOI manager failed to initialize.
Here is the connection string from above 2 files:
<url>jdbc:sqlserver://PTMTS-SOISPP-01.mch.moc.sgps/SAMStore;instance=SOIPP:52186<;databaseName=url>
<Property name="url">jdbc:sqlserver://PTMTS-SOISPP-01.mch.moc.sgps/SAMStore;instance=SOIPP:52186<;databaseName=Property>
Here is the JDBC connection string from hibernate.cfg.xml file (this looks good)
<property name="connection.url">jdbc:sqlserver://PTMTS-SOISPP-01.mch.moc.sgps\SOIPP:52186;databaseName=SAMStore</property>
Please update JDBC connection string as defined in hibernate.cfg.xml in above 2 files "\SOI\wso2registry\repository\conf\registry.xml, user-mgt.xml" and run these commands.
1. Stop SOI Manager services
2. Update above 2 files with correct JDBC string
3. Open a dos window, CD to the \CA\SOI\tomcat\registry folder and run " registryloader.bat"
4. Restart the SOI manager services
