How to limit the number of connection to DB

Hello

I just go to the topic of connection pooling.
Here, I would like to understand the number of details of connections that already exists in the database.

Kindly guide me to know the following details.

How to know the number of connections available in the database?
How to limit the number of connections?

V_$ Resource_Limit contains details of the sessions. Is this even for connections?

I have more clarification on the difference of connections and Sessions.

Kindly tell me the above.

Thank you

The number of currently active sessions (db, internal sessions registered)

to increase or decrease the maximum number of connections:

for example: change processes control system = 200 scope = spfile;

Connection means a user process is successfully connected to the listener to have a session on the database running instance. (listener who listen s new connection requests)
Establish sessions: means, a (dedicated) server process began to serve a user process. It is done when the credentials of the user authenticated successfully. Now, from process-user shall communicate to the server process directly.

hope that helps.

Kind regards

  • Is it possible to limit the number of connections to the remote panel to a vi?

    Hello

    I have an application that runs on a PXI RT system and I use the remote control to access. My license allows me to have several remote connections and it's ok that I sometimes need to open several remote panels at the same time.  However, I would like to limit the number of connections for a particular VI 1.  Is this something that can be done?

    Kind regards

    Patrick Lessnick

    The way it can be done is to interview customers who are connected to the VI through a remote façade.  When you do that, you close the connection to anyone, but the first person who connected to the façade.  In this way, if someone is running the VI, no one else can connect.  Once they are made, someone else can then connect to the remote façade.  I created an example illistrates community this behavior.  You can find it here:

    I want to restrict the number of connections to my pc for an incoming connection at a time.  I have several users that connect to my computer, using the same user name & password.  If someone tries to open a session, they fall out of someone who is already connected, without notice. the only solution I can think of is to limit the number of incoming connections to one.

    As previously reported by Duncan, no, there is no way to limit the number of snapshots. I also confirm that it is the same limit on vSphere.

    No way to do it directly from an ESX Server.  ESX will do this directly, by launching tasks and queuing the rest, if you started several at once, but I know no way to specify a value for this.
