ctldmp option to create transaction start files from checkpoints in transaction log files

The ctldmp utility allows you to create transaction log start files for the transaction logs that it scans. Specify the csf ("create start files") option to use this feature.

The start files are named S<lognumber>_<sequencenumber>.FCA, where lognumber is the transaction log number and sequencenumber is the checkpoint number in that log (starting from 1).

These start files can be renamed to S0000000.FCS and S0000001.FCS so that FairCom Server can use the checkpoint positions as starting points for automatic recovery.

Example:

# ctldmp log 1254 csf
