Create a Dbspace
From DB-Monitor
1. From within DB-Monitor, select the Parameters menu, Shared-
Memory option to change the maximum number of chunks. Change
the value in the field, Max # of Chunks.
2.
Reinitialize shared memory (take OnLine offline and then to
quiescent mode) for the change to take effect.
From the Command Line
1. To change the value of CHUNKS from the command line, use an
editor to edit the file specified by $INFORMIXDIR/etc/$TBCONFIG.
2. Change the value of CHUNKS. Reinitialize shared memory (take
OnLine offline and then to quiescent mode) for the change to take
effect.
Create a Dbspace
This section provides instructions for creating a dbspace.
Verify that you will not exceed the maximum number of blobspaces and
dbspaces allowed in your configuration, specified as DBSPACES.
You specify an explicit pathname for the initial chunk of the dbspace.
Informix recommends that you use a linked pathname. (Refer to page 1-22
for further information about the benefits of using linked pathnames. Refer
to page 2-93 for further information about selecting a chunk pathname. Refer
to page 1-43 for guidelines on how to determine where your chunks should
be located on disk.)
If you are allocating a raw disk device, you might need to specify an offset to
preserve track 0 information used by your UNIX operating system. (Refer to
page 1-49 for further information about how to determine if you need an
offset.)
If you are allocating cooked disk space, the pathname is a file in a UNIX file
system.
If you are logged in as user informix, you can create a dbspace within
DB-Monitor or from the command line. If you are logged in as root, you must
use the command-line option.
