Executing TCP/IP Application Programs
Connecting to TCP/IP
By default, your TCP/IP application will
attempt to connect with the TCP/IP partition that has been assigned
ID=00
. Refer to the corresponding TCP/IP stack
documentation on how to assign the ID to your TCP/IP stack. The default ID value
is "00". If you want to connect to a TCP/IP partition with an ID not equal to
"00", you can do so by including an appropriate OPTION statement in your
JCL:
// OPTION SYSPARM='xx'
In the above, xx is the two-digit ID number, coded exactly as in the TCP/IP startup JCL or parameters.
Preparation and Setup for SSL/TLS
Before using the LE/VSE C, EZASMI and EZASOKET function calls for secured socket communication, the VSE system must be prepared to use SSL for VSE.
This preparation work includes
- (Optional) Creation of the library and sublibrary where private key and certificates are to be stored (if default files on disk are not to be used).
- (Optional) Definition of library, sublibrary and member name to be used for private key and certificates (if default files on disk are not to be used)
- Creation of private key.
- Creation of server certificate.
- Creation of root certificate.
- (Optional) Verification of SSL for VSE Certificate.
Refer to Administering for a detailed description of this preparation work.
