ENABLE-CONNECTIONS( ) method

Specifies the TCP/IP port that the AVM uses to listen for new connections. Once called, the AVM automatically listens for and accepts new connections for the specified port.

Syntax
ENABLE-CONNECTIONS( `connection-parms` )

Table 77 describes the socket connection parameters you can include in this string.

Table 77: Socket connection parameters
Parameter	Description
`-S` `socket-port`	The TCP/IP port number that the AVM should listen to and accept connections on. You can specify either an explicit port number or a TCP service name. If you use a TCP service name, the method uses the port number associated with that name in the TCP/IP services file.
`-pf` `filename`	Optional. A text file containing any of the socket connection parameters described in this table. If this file contains any other OpenEdge startup parameters, this method ignores them.
`-qsize` `backlog`	Optional. The length of the pending-connection queue—that is, the maximum number of connection requests you want the server to queue while it processes the connections already accepted. If the queue is full when a connection request is received, it is refused. The default length of the queue depends on the platform. Note: On some platforms, the value you supply for `backlog` is modified by addition, subtraction, multiplication, division, or some combination of these, and it is this modified value that becomes the maximum length of the queue. For more information, see the documentation for your platform.
`-ssl`	If specified, the connection is SSL-based. Note: Be sure you need SSL before using this option. SSL incurs more or less heavy performance penalties, depending on resources and load.
`-keyalias` `aliasname`	Sets the alias name of the Public[/Private] key and digital certificate to use within the keystore. If not specified, the default `default_server` key alias is used.
`-keyaliaspasswd` `encpwd`	Sets the password to use in accessing the Public[/Private] key and digital certificate. Always specify a `-keyaliaspassword` when the `-keyalias` option is used. The default password only exists when using the `default_server` server certificate.
`-nosessioncache`	If specified, caching for the SSL client session is disabled.
`-sessiontimeout` [`seconds`]	The maximum amount of time, in seconds, that the server waits before it rejects a SSL client’s request to resume a session. The default value is 180 seconds.

Neither an AppServer nor a WebSpeed agent can act as a socket server, since they are already listening on a port. ENABLE-CONNECTIONS is only valid from batch clients, GUI clients and character clients. This method will generate an error if it is called from an invalid application. This method will also generate an error if it is called multiple times without the DISABLE-CONNECTION( ) method being called in between.
