Managing the SLggguuu Log File
SLggguuu file is an entry-sequenced file. It is created with primary and secondary
extent sizes of 32 and 64 pages respectively, and with a maximum of 500 extents. The
log file stores a maximum of 15900 records.
AutoSYNC does not delete records from the log until the file fills up, at which point
Autosync deletes the records for oldest day in the log file. If the volume of
synchronization for a given user is such that the AutoSYNC log file fills up in less than
a day, you can create a larger log file. There are two options:
1. Create a new larger log file

In AutoSYNC CI, suspend the activity for the syncuser:

In FUP, rename the current log file and create the new file:

In AutoSYNC CI, reactivate the synchronizations for the syncuser:
The log file is opened once, when the synchronization process starts up.
SUSPEND stops the synchronization process and ACTIVATE restarts the
synchronization process. The sequence of SUSPEND and ACTIVATE command
thus forces the switch to the new larger log file.
2. Increase the size of the current log file.
This operation can be done without suspending the active synchronizations. Use
FUP to increase the value of MAXEXTENTS:
By setting MAXEXTENTS to the maximum value, you nearly double the size of the
log file, increasing its capacity from approximately 31,000 records.I
