netstat is probably the best way to go. Use some combination of grep-ing for certain patterns, like obvious connection strings, port number, etc.
For example:
should provide output whether a connection is being established on port 1521, which is the default Oracle Listener port. Just use your DB server specifics to manage the part after the grep.
Another possibility would be "lsof" if you have it installed, check its man pages.

CLUSTERDB(1) PostgreSQL Client Applications CLUSTERDB(1)NAME
clusterdb - cluster a PostgreSQL database
SYNOPSIS
clusterdb [ connection-options... ] [ --table | -t table ] [ dbname ]
clusterdb [ connection-options... ] [ --all | -a ]
DESCRIPTION
clusterdb is a utility for reclustering tables in a PostgreSQL database. It finds tables that have previously been clustered, and clusters
them again on the same index that was last used. Tables that have never been clustered are not touched.
clusterdb is a shell script wrapper around the backend command CLUSTER [cluster(7)] via the PostgreSQL interactive terminal psql(1). There
is no effective difference between clustering databases via this or other methods. psql must be found by the script and a database server
must be running at the targeted host. Also, any default settings and environment variables available to psql and the libpq front-end
library do apply.
clusterdb might need to connect several times to the PostgreSQL server, asking for a password each time. It is convenient to have a
$HOME/.pgpass file in such cases.
OPTIONS
clusterdb accepts the following command-line arguments:
-a
--all Cluster all databases.
[-d] dbname
[--dbname] dbname
Specifies the name of the database to be clustered. If this is not specified and -a (or --all) is not used, the database name is
read from the environment variable PGDATABASE. If that is not set, the user name specified for the connection is used.
-e
--echo Echo the commands that clusterdb generates and sends to the server.
-q
--quiet
Do not display a response.
-t table
--table table
Clusters table only.
clusterdb 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 host begins with a slash, it is used as the directory for
the Unix domain socket.
-p port
--port port
Specifies the Internet TCP/IP 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
--password
Force password prompt.
DIAGNOSTICS
CLUSTER
Everything went well.
clusterdb: Cluster failed.
Something went wrong. clusterdb is only a wrapper script. See CLUSTER [cluster(7)] and psql(1) for a detailed discussion of error
messages and potential problems. Note that this message may appear once per table to be clustered.
ENVIRONMENT
PGDATABASE
PGHOST
PGPORT
PGUSER Default connection parameters.
EXAMPLES
To cluster the database test:
$ clusterdb test
To cluster a single table foo in a database named xyzzy:
$ clusterdb --table foo xyzzy
