C. Restart your J2EE server (Server0) as your last option.
SAP MMC > J2EE services > Server0 > Right click > Restart Process.
Wait to load and try again. This solved our problem.

1.5 Go to Service > Select the Parameter that you want to change.

1.6 Perform the needed change

*Note confirmation 1.7 and 1.8 must be in order else you will get notice that changes are not applied.

1.7 Press 'Update' to update database

1.8 Press save button. (Floppy disk button)

1.9 Logout and login to your visual administrator again to confirm if change has been done as per step 1.1 to 1.4.

This is part 3 of BB note 004. Hope this helps.
