Using Configuration Files

Use configuration files to set default parameters for CA XCOM Data Transport transfers. Use xcom.cnf to change default settings or to set transfer-specific variables for an individual locally-initiated transfer. You may have any number of different .cnf files with different names.

CA XCOM Data Transport reads the .cnf parameter file specified, or it reads $XCOM_HOME/config/xcom.cnf if no configuration file is specified. It then reads any parameters specified on the command line, and then executes the specified file transfer. CA XCOM Data Transport will also automatically use the defaults from the xcom.glb file to supply any parameter values not specified elsewhere. For each transfer, CA XCOM Data Transport compiles a full set of parameter values. To collect these values, the program follows a search sequence. The values are collected in the following order:

1. The CA XCOM Data Transport program defaults.
2. Parameters defined in xcom.glb at the time the CA XCOM Data Transport daemon was started.
3. Parameters defined in the specified .cnf file.

   If a copy of the configuration file is not found in the current directory, then the file $XCOM_HOME/config/xcom.cnf is used. If a .cnf file is specified, the parameters are not picked up from the xcom.cnf.

4. Parameters defined in the command line following the -f option.

Note: Use a text editor to modify the values in xcom.cnf. All modifications go into effect the next time a transfer is initiated.

For a description of how parameter values take precedence, see Using CA XCOM Parameters in the chapter "Operating Environment." For a complete list of CA XCOM Data Transport parameters see the appendix "Parameters."
