The following material:

• Where the physical log is located in the chapter on what is the physical log in the IBM Informix: Administrator's Guide
• Changing the physical-log location and size in the chapter on managing the physical log in the IBM Informix: Administrator's Guide

PHYSDBS specifies the name of the dbspace that contains the physical log for a particular coserver. To reduce disk contention, you can move the physical log to a dbspace other than the root dbspace.

When you initialize disk space (oninit -i), the PHYSDBS value must be equal to the ROOTDBS value.

If you use the PHYSSLICE parameter to locate your physical logs in a dbslice, you can list the PHYSDBS parameter in the coserver-specific section of your ONCONFIG file to change the location of the physical log on a specific coserver.
