Password expiration management has been enhanced to include the External Security Interface (ESI). The ESI is not part of CICS® Transaction server for z/OS, but it allows a non-CICS application to invoke services provided by advanced APPC PEM. ESI provides additional functions which make it easier for a non-CICS application to change and verify a password.
These functions allow a non-CICS application program to act as a PEM requestor without the application programmer having to manage an APPC conversation which implies knowledge of the formats for PEM requests and replies, and of the interface to the local SNA server.
For more information about the ESI password management functions, see the Client/Server Application Programming manual.
