information saved in the system log from a previous run. The primary and
secondary system log streams are purged and CICS begins writing a new system
log.
v Because CICS is starting a new catalog, it uses a new logname token in the
“exchange lognames” process when connecting to partner systems. Thus, remote
systems are notified that CICS has performed a cold start and cannot
resynchronize.
v User journals are not affected by starting CICS with the START=INITIAL
parameter.
Note: An initial start can also result from a START=COLD parameter if the global
catalog is newly initialized and does not contain a recovery manager control
record. If the recovery manager finds that there is no control record on the catalog,
it issues a message to the console prompting the operator to reply with a GO or
CANCEL response. If the response is GO, CICS performs an initial start as if
START=INITIAL was specified.
For more information about the effect of the state of the global catalog and the
system log on the type of start CICS performs, see the CICS System Definition
Guide.
