What is the NULLID package collection for?? As far as my knowledge goes it is a collection of all the packages for system level procedures.Can any one here give me more details about the packages inside NULLID collection?Any links will be helpful.

I also have a doubt about the NULLID packages that we see in db2detailed deadlock event monitor output.How are they related to the locks and deadlocks?? What does the isolation level on these packages signify??


Thanks

you are correct, nullid schema packages are system type ones. afaik, there is no definitive documented list of nullid packages ... they keep changing all the time .... If you want info on any of them, google for them and/or search the IBM support site.
