IBM Informix OnLine Database Server Administrator’s Guide

The space allocated for the physical log must be contiguous. If you move the
log to a dbspace without adequate contiguous space or increase the log size
beyond the available contiguous space, a fatal shared-memory error occurs
when you attempt to reinitialize shared memory with the new values.

Changes to the physical log do not take effect until you reinitialize shared
memory: that is, take OnLine offline and then back to quiescent or online
mode. To immediately reinitialize shared memory, execute the command
with the -y option.

Create a level-0 archive immediately after you reinitialize shared memory.
This archive is critical for proper OnLine recovery.
