Hi all,

I'm currently facing a problem with a Db2 database.
When I try to activate / connect to it, following error occurs :

---------------------------------------------------------
"SQL1226N The maximum number of client connections are already
started.
SQLSTATE=57030"
---------------------------------------------------------

I had a look to db2diag.log,
and found followings :

I 'm (unfortunately) not a DB2 specialist, nor AIX guru,
and would really appreciate any help.

Thanks

It seems that maxagents or something similar has been reached. To narrow down
the problem, I would need the output of:

db2 get dbm cfg
db2 get db cfg for <dbname>
db2 list applications

Please run those commands as db2inst1 and post them here.

check max_connections dbm cfg. it may be too small for your

Since it says that:
"Overflow agent is not allowed for gateway connection"
It may be that you are trying to use the embedded DB2 Connect facilities to
connect to a remote database. For DB2 Server products that come licensed
with DB2 Connect, it has a max of 5 connections allowed to remote databases.
