Hello,

I installed v9.7 ESE with default "db2admin" konto, as I use another user konto to login in Win7, got an system error "SQL5005C", but with "db2admin" is ok. how can I fix it ?

follow shows the part of infos with db2diag:

2011-07-06-12.36.50.360000+120 I47011F484 LEVEL: Error

looks like permission issue.
Check your konto user account, if its available as OS user and you granted permission for this user for your database.
