File Sharing With CA-L-Serv

When using CA-L-Serv, CA TPX accesses the VSAM files through the CA-L-Serv file server component. Only CA-L-Serv has direct access to the files. It takes read and write requests from CA TPX and determines the correct VSAM file to access.

Control record zero, which contains VSAM sharing information when CA-L-Serv is not used, is deleted when the VSAM files are opened for update.
