ZSCAN Available Commands
Chapter 5 137
DSC - Dynamic System Configuration
Format: dsc
This command shows some internal kernel information about the
dynamic system configuration of the ZCOM subsystem. The DSC feature
allows the ZCOM configuration (as defined in the TTGEN file) to be
modified while the system is running. When a DSC request is
in-progress, some system activities must be suspended.
zscan> dsc
Total number of DSC requests = 17
Number of active requests = 0
Number of DSC or lock waiters = 0
The above shows the total number of DSC requests that has been
processed, the number of DSC requests that is in-progress, and the
number processes suspended because there is active DSC request.
If the number of active requests is negative (i.e. -1), DSC are disabled
and any such request will be rejected with an error.
EN - List System Parameters
Format: en
The EN (or environment) command is used to display information about
the ZCOM subsystem global parameters. As well as displaying the
names of the source and object files, the EN command also returns table
addresses and sizes of the Interface Tables, Physical Terminal tables,
Logical Terminal tables, Queue Headers, and Buffer pool. These tables
can be examined in more detail by using other ZSCAN commands.
Most of the parameters displayed here are setup from the entries in the
TTGEN configuration file. Refer to the section on TTGEN for more
details.
