A good one to keep an eye out for in performance testing, cheers Paul. Mmm… not entirely convincing response. A good one to keep an eye out for in performance testing, cheers Paul.

(Incidentally, how bad is Metalink???!!!): You are correct in that in the OOTB functionality the BC Picklist Generic have the cache set to 'FALSE'. The reason for this is that as standard the performances of picklists are not an issue and the data does not need to be cached. However, the performance guide: Siebel Performance Tuning Guide > Tuning Customer Configurations for Performance > Best Practices for Business Objects Layer > Using Properties to Improve Picklist Performance states: To cache the content of certain picklists for subsequent use in the same user session, the property Cache Data property should be set to TRUE for the PickList Generic business component. By default, this property is TRUE. The information in the first line is correct and that to aid performance with picklists, the cache data setting should be set to TRUE. The second line of this statement is incorrect and the default setting in v 8.0.0.1 as you know is FALSE. I have therefore raised a documentation defect CR#12-1MVR1AT. In your case you have performance issues with your picklists and I would set the cached data setting to be TRUE so that this is cached and the performance should improve.

It's interesting, too, since in the <a href="http://download.oracle.com/docs/cd/B40099_01/80Siebel_HTML/books/PerformTun/PerformTunCustConfig16.html" rel="nofollow">v8 docs</a> Oracle still use Picklist Generic as an example of where Cache Data <i>should</i> be True...
