Explanation:
Beginning with Domino 8.5, the format of transaction logs can be optimized
for Domino servers that use a block size different than the default block
size of 512 bytes.
The NOTES.INI option Create_R85_Log=1 will create new transaction logs
with an updated format, properly aligning blocks for I/O.
Default:
When Create_R85_Log is absent or set to '0', the default behavior is to
use the default size of 512 bytes for I/O block alignment.
Recommendation:
Bring down the server. Back up existing transaction logs, then delete them.
Set Create_R85_Log=1 in the server NOTES.INI and restart the Domino
server to have new logs created using the updated format. The new
logs will have properly aligned I/O blocks. There is no need to verify
the current block size. Domino will use correctly format the log even if
the block size is 512.
Restrictions:
This option is only available with Domino 8.5 and later.
Restarts:
The Domino server must be restarted after modifying this setting.
