Hot Connection to a Server
With CONNX, you can create a hot connection to an OpenVMS server that enables a connection to remain open. Leaving a connection open helps shorten the length of time it takes to connect to a server, which can be beneficial to users who are opening and closing connections repeatedly or who are operating in an environment where a high volume of short connections are made, as with Web servers. The number of open connections should be kept to a minimum in order to maintain the highest levels of VMS system performance.
Important:
An open server connection decreases the security of data stored on that server.
To open a hot connection to a server:
1. Connect to the VMS server with which you are working.
2. In a terminal emulator, type the following DCL command and press <Enter>:
$ SET DEF CNXDIR
3. Type the following DCL command and press <Enter>:
$ RUN CNXHOT
4. Type a VMS user name, using uppercase characters, and press <Enter>.
5. Type a VMS password, using uppercase characters, and press <Enter>.
6. Define a system-level logical that determines the number of prestarted servers for each type of database.
For RMS databases:
DEFINE /SYSTEM CNXRMSSERVERCOUNT
number of prestarted servers
For Rdb databases:
DEFINE /SYSTEM CNXRDBSERVERCOUNT
number of prestarted servers
For DBMS databases:
DEFINE /SYSTEM CNXDBMSSERVERCOUNT
number of prestarted servers
7. Restart the CONNX Listener process.
