Before starting Business Continuity manager, use the YKSETENV command to set Business Continuity Manager environment variables.

A re-IPL will invalidate Business Continuity Manager environment variables set using the YKSETENV command. Therefore, we recommend that you use one of the following methods to automatically set Business Continuity Manager environment variables when a re-IPL takes place:

  • Add the YKSETENV command to the COMMNDxx parmlib member.
  • Specify values for the system symbols in the IEASYMxx parmlib member, which correspond to the Business Continuity Manager environment variables.

After setting the Business Continuity Manager environment variables, use the YKDSPENV command to verify that they have been specified correctly.

For details about the YKSETENV command format, see YKSETENV command format. For details about the YKDSPENV command format, see YKDSPENV command format.

The following table describes the Business Continuity Manager environment variables that can be set, their meanings, their corresponding system symbol names, and their default values.

Table. Business Continuity Manager environment variables that can be set

Business Continuity Manager environment variable

Meaning

Corresponding system symbol names

Default value

YKCMDIF

Host ID

&YKCMDIF

00

YKLCNSE

YKLCNS2

Prefix of the license information dataset

&YKLCNSE and &YKLCNS2

HITACHI#1

LOGPUT

Whether the system logger service#2 is used

&YKLOGPT

LOGR: Uses the system logger service

SYSLOG

Whether CLI command-execution logs are output to SYSLOG or the console

&YKSYSLG

YES: Outputs CLI command-execution logs to SYSLOG

#1: For details about the relationship between the prefix of the license information dataset and the specification status for the YKSETENV command or IEASYMxx parmlib member, see section Naming for license information datasets.

#2: For details about the system logger service, see the Hitachi Business Continuity Manager User Guide.

Alternatively, you can define the corresponding system symbols in the IEASYMxx parmlib member and then perform a re-IPL of the system to set values for the Business Continuity Manager environment variables. If you cannot perform the re-IPL because the system is running, use the YKSETENV command to set environment variables.

The priority order for specifying values is as follows:

  1. value-specified-by-the-YKSETENV-command
  2. value-specified-for-the-IEASYMxx-parmlib-member
  3. default-value

If the YKSETENV command is executed without specifying parameters, the corresponding system symbol values are used as the Business Continuity Manager environment variables. If no value is specified for the YKSETENV command parameters and the corresponding system symbols, the default values are used as the Business Continuity Manager environment variables.

The following sections provide examples of configuring the environment. For details about how to specify the prefixes for license information datasets, see section Naming for license information datasets.

Note: If you use the YKSETENV command to set Business Continuity Manager environment variables, perform the procedure described in section Settings for using CLI commands in TSO/E environments.
