I will give you more than one solution maybe it will be related to the above problem and you try them separately to see which one will be valid for you : 

1-Netowrk Parameters :

You will find it $ORACLE_HOME/forms/server/default.env
Just increase the value .

2-do the following change in opmn.xml (under $ORACLE_HOME/opmn/conf/):


3-SET Inbound_connection_timeout In sqlnet.ora to ZERO .

Sqlnet.Inbound_connection_timeout = 0

Note : if your can’t find this parameter in the SQLNET.ORA you cant add it .

5- Change the following $ORACLE_HOME/opmn/conf/opmn.xml

Hope this will work
