Good Morning.

I'm experiencing an issue when attempting to create a Maintenance Plan on a SQL 2008 server. Here is the report:


Maintenance Plan Wizard Progress

- Creating maintenance plan "Daily SQL Maintenance" (Success)

- Adding tasks to the maintenance plan (Success)

- Adding scheduling options (Success)

- Adding reporting options (Success)

- Saving maintenance plan "Daily SQL Maintenance" (Error)
Messages
Saving maintenance plan failed.

------------------------------
ADDITIONAL INFORMATION:

Invalid class string


------------------------------

Invalid class string

 


Any clues?

Thanks

Yes, SP1 is applied. And I've tried performing the maintenance tasks as the actual SA user

Just some additional information... if I click the wizard, I get the error described above. If I click straight into "right click maintenance plans and click new maintenance plan", I get the error straight away:

"exception has been thrown by the target of an invocation. (mscorlib)
Additional Information:
Invalid class string
Invalid class string"

When you installed SQL Server 2008 did you install Integration Services?

If you did not install Integration Services then you cannot create Database Maintenance Plans.

Database Maintenance Plans are SQL Server Integration Services packages which require Integration Services to run.

Run the installation program again and add Integration Services to your server and you Database Maintenance Plans should work.

You are right wolfman007, silly me, I did not install the SQL Integration Services packages. After installing that I could create the maintenance plans no worries.

Thanks for the help
