Which Parameters to Specify for a Log Stream Definition

Business Continuity Manager assigns a log stream for each system. Even in a Sysplex environment,
there is a log stream for each system where Business Continuity Manager is running.
This section explains which parameters to specify when defining a log stream with the IXCMIAPU
utility.
NAME(log_stream_name)
The name of the log stream is CCENTRAL.LOG.system-name. For system-name,
specify the system symbol's system name (&SYSNAME).
If a system name starts with a number, Business Continuity Manager forms the log
stream name by taking the last five characters from the system name and appending
them to YKS. Therefore, if a system name starts with a number, the substring used
for the log stream name must be unique in the Sysplex.
The following example shows how the system name starting with a number is
converted to the system name with a log stream name:
System name 1SYS starts with a number and contains fewer than 5 characters.
Business Continuity Manager appends 1SYS (4 characters) to YKS and creates
the system name YKS1SYS.
System name 1SYSTEM starts with a number and contains more than 5
characters.
Business Continuity Manager appends YSTEM (the 5 last valid characters) to
YKS and creates the system name YKSYSTEM.
System name 1SYSTEM and 2SYSTEM both start with numbers and contain
more than 5 characters.
The log stream names for both systems are YKSYSTEM and are thus identical.
It might be necessary to change the system name specified in IEASYSxx.
For details on system names, see the MVS Initialization and Tuning Reference.
DASDONLY(YES)
The log stream is a DASD-only log stream.
A log stream in the system logger service is either a coupling function log stream
or a DASD-only log stream. Since a coupling function log stream is not required
for Business Continuity Manager, the DASD-only log stream should be selected.
