****************************************************************
Local Fix:
Deactivate database before execute db2support 
or 
Run db2support . -d <dbname> -st "values 1" -g -c 
Then it exports catalog tables to ixf files, instead of running 
db2dart /DDEL 
 
You need to specify -F or -full option in db2support command 
when you like to collect the other files except db2diag.log in 
DIAGPATH directory along with optimizer collections like below. 
  db2support -d <dbname> -st "values 1" -F
