Setting Shared Memory Parameters

Setting Shared Memory Parameters
Like the disk parameters screen, the shared-memory parameters screen
appears with some default values in some fields. In the following represen-
tationof the shared-memory parameters screen, each default value has been
replaced with the name of the OnLine configuration parameter associated
with that field:
Enter the values for each parameter. After you verify that the values are
correct, pressESC to indicate that you wish to record your changes. OnLine
prompts a verification:
Do you want to keep these changes to the parameters (y/n)?
If you enter n for no,DB-M onitor returns to the Parameters menu. You can
begin again if you wish.
Ifyou enter yfor yes, OnLine stores the configuration parameter values in the
currentconfiguration file, if one exists. If no configuration file exists, OnLine
creates a configuration file for you. The file OnLine creates is placed in the
$INFORMIXDIR/etc directory. The configuration file is named according to
thevalue specified by TBCONFIG, if it is set. If TBCONFIG is not set, the file is
namedtbconfig by default.
