Purging old data from the database used by VMware vCenter Server 4.x and 5.x (1025914)

Hi,

I am trying to reduce the size of the database, currently 190GB using scripts supplied in the VMWare KB article 1025914

Unfortunately when I run the script I am getting error below:

Msg 4440, Level 16, State 9, Line 1

UNION ALL view 'vCenter.dbo.VPX_HIST_STAT4' is not updatable because a primary key was not found on table '[vCenter].[dbo].[VPX_HIST_STAT4_1]'.

And no data deleted.

Could you provide updated scripts or advise how to resolve this error?

Regards

DBA
