Connection time out from Database

Hi,

Hi we have application running on Unix Server(solaris10), which establishes connection(sessions) with DATABASE(oracle 10g) which is on another server and firewal is there in between. After some time i am usually getting connection time out(oarcle error 3114/3113) in some of my processes which were idle for sometime.

we have set idle time UNLIMITED in our database.Is there any rules in firewal??
Also i am using cluster Ip for both application and for database. I mean there is a clustering for Application as well as database.

thnks and regards

dropdb

DROPDB(1)						  PostgreSQL 9.2.7 Documentation						 DROPDB(1)

NAME

       dropdb - remove a PostgreSQL database

SYNOPSIS

       dropdb [connection-option...] [option...] dbname

DESCRIPTION

       dropdb destroys an existing PostgreSQL database. The user who executes this command must be a database superuser or the owner of the
       database.

       dropdb is a wrapper around the SQL command DROP DATABASE (DROP_DATABASE(7)). There is no effective difference between dropping databases
       via this utility and via other methods for accessing the server.

OPTIONS

       dropdb accepts the following command-line arguments:

       dbname
	   Specifies the name of the database to be removed.

       -e, --echo
	   Echo the commands that dropdb generates and sends to the server.

       -i, --interactive
	   Issues a verification prompt before doing anything destructive.

       -V, --version
	   Print the dropdb version and exit.

       --if-exists
	   Do not throw an error if the database does not exist. A notice is issued in this case.

       -?, --help
	   Show help about dropdb command line arguments, and exit.

       dropdb also accepts the following command-line arguments for connection parameters:

       -h host, --host=host
	   Specifies the host name of the machine on which the server is running. If the value begins with a slash, it is used as the directory
	   for the Unix domain socket.

       -p port, --port=port
	   Specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections.

       -U username, --username=username
	   User name to connect as.

       -w, --no-password
	   Never issue a password prompt. If the server requires password authentication and a password is not available by other means such as a
	   .pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user is present to enter a
	   password.

       -W, --password
	   Force dropdb to prompt for a password before connecting to a database.

	   This option is never essential, since dropdb will automatically prompt for a password if the server demands password authentication.
	   However, dropdb will waste a connection attempt finding out that the server wants a password. In some cases it is worth typing -W to
	   avoid the extra connection attempt.

       --maintenance-db=dbname
	   Specifies the name of the database to connect to in order to drop the target database. If not specified, the postgres database will be
	   used; if that does not exist (or is the database being dropped), template1 will be used.

ENVIRONMENT

       PGHOST, PGPORT, PGUSER
	   Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see Section 31.14, "Environment
       Variables", in the documentation).

DIAGNOSTICS

       In case of difficulty, see DROP DATABASE (DROP_DATABASE(7)) and psql(1) for discussions of potential problems and error messages. The
       database server must be running at the targeted host. Also, any default connection settings and environment variables used by the libpq
       front-end library will apply.

EXAMPLES

       To destroy the database demo on the default database server:

	   $ dropdb demo

       To destroy the database demo using the server on host eden, port 5000, with verification and a peek at the underlying command:

	   $ dropdb -p 5000 -h eden -i -e demo
	   Database "demo" will be permanently deleted.
	   Are you sure? (y/n) y
	   DROP DATABASE demo;
