ICAP SHOW
Name
ICAP SHOW - Show the status and settings of the iCAP software on the OpenVMS system. (HP-UX
equivalent: icapstatus)
Format
ICAP SHOW STATUS [qualifiers]
Parameter

ICAP_SERVER
Name
ICAP_SERVER - iCAP server process.
Description
The ICAP_SERVER process performs the same functions as the icapd daemon process on HP-UX
systems. For more information, see the HP-UX icapd manpage. To ensure compliance, the
ICAP_SERVER is always running on OpenVMS systems in an iCAP complex.
Special OpenVMS-Specific Features and Considerations
Core Activation and Deactivation
Unlike HP-UX, the OpenVMS operating system provides a user interface to start and stop system
processor resources. When you enter the START /CPU command on an OpenVMS system in a
complex containing iCAP resources, the ICAP_SERVER process validates that the start operation
does not take the complex out of compliance. When you enter the STOP /CPU command, the
CPU might restart at a later time if the count of intended active cores on the system is greater than
the actual active cores.
IMPORTANT: The ICAP command or the corresponding HP-UX foreign commands must be used
on OpenVMS systems when stopping and starting in complexes containing iCAP components.
Using the START /CPU command can result in unintended consequences, such as an unexpected
usage of temporary capacity or the deactivation of cores on the system or on another system in
the complex. Using the STOP /CPU command can result in an unexpected restart of the core or
the unexpected start of a core in another system in the complex.
To start cores on OpenVMS, use the ICAP ACTIVATE/CPU= command. To stop cores on
OpenVMS, use the ICAP DEACTIVATE/CPU= command.
Email Considerations
The iCAP software requires that SMTP mail be configured on the OpenVMS system to send email
to the system contact. For more information about setting up SMTP mail, see your IP provider’s
documentation.
