LOG command and call
You can use the LOG request online when you want a record to be written from an application program to the IMS log. Your program can specify whatever information you want to be on the log. You may prefer to use it instead of EXEC CICS journal commands so that all your DBCTL information will be on the IMS log instead of the CICS® log.
IMS uses different log codes to distinguish different types of log record. All user log records in the IMS log have the same code. Records logged using the LOG request will not be backed out if synchronization fails and the UOW is canceled.
