DB2 FOR LUW / DB2FORLUW / A10 - DB2

If an application on a Windows database server is forced, the 
client program for that application hangs next time it runs a 
query. 
 
This problem does not happen for database servers on any 
platform other than Windows. 
 
Here are steps which reproduce the problem: 
 
On the database client, connect to a database that is on a 
Windows database server. 
For example, run: 
 db2 "connect to <database> ..." 
  (substituting for <database> the name of the database on a 
Windows database server) 
 
On the Windows database server, force the application. 
For example, run: 
 db2 "list applications" 
 db2 "force application (<app-handle>)" 
  (subsituting for <app-handle> the application handle that was 
output by "list applications") 
 
On the database client, using the client program for the 
application that you forced, run any SQL statement. 
For example, run: 
 db2 "select count(*) from syscat.tables" 
 
At this point the client program ought to get error: 
"SQL30081N  A communication error has been detected." 
But because of this defect it hangs instead. 
 
Now if you stop the stop the DB2 instance on the Windows 
database server the client program is no longer hung but gets 
the error: 
"SQL30081N  A communication error has been detected."

As a workaround to prevent the client program from hanging 
indefinitely, you can set 
the DB2 registry variable DB2TCP_CLIENT_RCVTIMEOUT on the 
database client to the number of seconds that the client program 
should wait before it gets the SQL30081N error.

Problem was first fixed in Version 10.1 Fix Pack 1. 
At a minimum, this fix should be applied on the database server.
