DSNJ015I CSRONLY PROHIBITS LOG ALTERATIONS. RECORD rrr CREATED .... REPLY Y TO USE, N TO CANCEL.

Explanation
  During Db2 startup,
the log manager found an inactive conditional restart control record
in the bootstrap data set. Because this control record indicates CSRONLY,
no log data sets will be modified. If log truncation was specified,
it will be simulated. Only the first phase of restart (current status
rebuild) will be performed. The hexadecimal identifier (rrr) and creation
timestamp (yy.ddd hh:mm) identify the record found.

System action
  A 'Y' reply will continue the conditional restart.
A 'N' reply will terminate Db2 startup.

Operator response
  To continue this CSRONLY processing, reply
'Y' to this message. If you are not sure, contact the system programmer.

System programmer response
  The conditional
restart control record will not be deactivated at the end of the CSRONLY
processing. To deactivate this record, either cancel this record or
create a new record. If you suspect an error in Db2, you might need to report the problem. For information about identifying and reporting the
problem, see Collecting diagnostic data.
