Hi, Is there any way to check which all things available in Oracle 10G , are not available in 11G. I am just trying to gather if there is anything our application was using while it was running in 10G and in any case, it is not available in 11G. I hope everything must be forward compatible. I am sure there will be only new additions.just to confirm... please help if there is any way to check this. Many Thanks, Sreejith Nair DISCLAIMER: "The information in this e-mail and any attachment is intended only for the person to whom it is addressed and may contain confidential and/or privileged material.
