DB2 - Problem description

Problem IC78650 Status: Closed

CAN NOT RETRIEVE DEFINED VALUES FOR REGISTRY VARIABLES WHEN
"DB2SET" COMMAND IS BEING PERFORMED.

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
When an application is performing "db2set" command to update 
registry variables, other applications running simultaneously 
might not be able to retrieve defined values for registry 
variables, as if the registry variables have not been set at 
all. 
 
The problem occurs only in a very rare situation. It's most 
likely to happen when registry variables are frequently updated 
by "db2set" command.
