The DBSPACETEMP environment variable specifies dbspaces that the database server can use to store temporary tables for a particular session. Using DBSPACETEMP can improve performance.
DBSPACETEMP specifies the location of dbspaces or dbslices. If DBSPACETEMP is not set, the default location is NOTCRITICAL.
For further information about DBSPACETEMP, refer to the chapter about configuration parameters in the IBM Informix: Administrator's Reference. For performance considerations, refer to your IBM Informix: Performance Guide.
The TERM, TERMCAP, TERMINFO and INFORMIXTERM environment variables specify the type of terminal interface. The basic login procedure usually sets the TERM environment variable. This environment variable is not required for initialization, but it must be set before you can run an application. The other three environment variables might be required, depending on your environment. You might need assistance from the UNIX system administrator to set these variables because they are highly system dependent.
