The following material in the IBM Informix: Administrator's Guide:

• Chapter on managing disk space
• Setting the global configuration parameters in the configuration-parameter chapter

The ROOTSLICE parameter specifies a name for the root dbslice. The ROOTSLICE parameter is a global configuration parameter. You cannot specify it in the coserver-specific section of the ONCONFIG file.

The name must be unique among all dbspaces that the database server manages. It is recommended that you select a name that is easily recognizable as the root dbslice.

If you specify ROOTSLICE, the database server derives a dbspace name for the root dbspace on each coserver. This dbspace name has the following format, where n is the coserver identification number:

rootslicename.n

The derived dbspace name for each root dbspace contains a period and a coserver number. The total name, including the period and coserver number, must not exceed 128 characters. Valid characters are restricted to digits, letters, and the underscore character. If the dbspace name is derived, it can include a period.
