-          Review system out and ffdc logs for any specific error messages and act on them

-          Make sure that the file system permissions are good (if it was owned by root and trying to start the server with wasadmin?)

-          Try executing this script: ${WAS_HOME}/bin/iscdeploy.bat –restore (details: http://publib.boulder.ibm.com/infocenter/eruinf/v2r2/index.jsp?topic=/com.ibm.tool.doc/deploy_comp1.html)

Could not find stored procedure 'master..xp_jdbc_open2'

If you see the following error while using MS SQL Server data source in WAS the solution is simple:

java.sql.SQLException: [IBM][SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open2'.DSRA0010E: SQL State = HY000, Error Code = 2,812

When creating a SQL datasource via the WAS Admin Console, you'll notice that certain custom properties are added 'out of the box'.  Above error will occur when enable2Phase custom property is true. Try changing this property to true in your script or add the property manually via the console.
