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.
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.
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.
This option is only available with Domino 8.5 and later.
The Domino server must be restarted after modifying this setting.
