CA-L-Serv Operation

CA-L-Serv services are provided by a general purpose entity called the CA-L-Serv kernel and the three servers activated by the kernel.

The CA-L-Serv kernel provides three core services for client applications: logging, messaging, and command processing. Through the kernel, you start and stop CA-L-Serv servers, issue commands to those servers, and perform routine maintenance operations, such as file backup and restoration.

The CA-L-Serv servers that run in the CA-L-Serv address space are:

• Communications Server provides cross system communications for client applications.
• File Server manages centralized access to VSAM files used by client applications.
• SQL Server provides SQL access to data stored in relational tables created from VSAM files.
