We are updating our SD 4.5 SP24 environment to SP28. After running the server update and restarting the server I started the DB configuration wizard. However, the wizard still shows SP24 as the current version which makes the DB update impossible. Have read the installation instructions but I cannot find anything useful.
That means that the installation was not successful. The quickest way to fix it is go to the server installation directory\lib and rename/delete servicepack.jar. Reinstall the service pack for the server and this should fix it.
Finally, I uninstalled the application server, installed the original application server and then applied the SP again. This worked as well and only took me like 10 minutes to do. Thanks anyway for your replies. I submit some points to you.
