Server-side Mapping Files

Server-side mapping files have the extension .svm.

Server mapping files with extension .svm are no longer supported at design time by the Designer. You can still use them at runtime in a server-side mapping container. All special COBOL syntax and features supported by server mapping files with extension .svm are also covered by server mapping files with extension .cvm. See When is a Server Mapping File Required? We recommend migrating .svm files to .cvm files. See Migrating Server Mapping Files under Server Mapping Files for COBOL in the Designer documentation. This document covers the following topics:

Server-side Mapping Files in the RPC Server

Server-side mapping files (.svm) are stored as ordinary files in the server-side mapping container folder.

  • If no server requires server-side mapping (.svm) or you are using server mapping files with extension .cvm only, you can omit the property cics.mapping.folder.

  • If one server requires a server-side mapping file (.svm), provide the property cics.mapping.folder. See Configuring the CICS ECI Side.

Undeploying Server-side Mapping Files from the RPC Server

Undeploy a server mapping file (Designer file with extension .svm) from the RPC server manually. See Server Mapping Files for COBOL.

Change Management of Server-side Mapping Files

Under UNIX and Windows, change management for a directory or folder (server-side mapping container, see Server-side Mapping Files in the RPC Server) is similar to change management within ordinary operating system directories (folders). All updates to the directory or folder done after a backup must be kept.

All Designer server-side mapping files (.svm) added since the last backup should be available. See Server Mapping Files for COBOL in the Designer documentation.

List Deployed Server-side Mapping Files

Use the Windows Explorer or the UNIX ls command to list the contents of the server-side mapping container (directory or folder). See Server-side Mapping Files in the RPC Server.

Check if a Server-side Mapping File Revision has been Deployed

Server-side mapping files in the server-side mapping container correspond to Designer file with extension .svm (same format). See Server Mapping Files for COBOL in the Designer documentation. Each line relates to an IDL program and contains a creation timestamp at offset 276 (decimal) in the format YYYYMMDDHHIISST. Precision is 1/10 of a second. The creation timestamp can be checked.

The timestamp can be found on the same offset in the server-side mapping files stored in the server-side mapping container (directory or folder). See Server-side Mapping Files in the RPC Server.
