3.2.2 ACP Installer
The ACP Installer is an interactive program that allows you to
• Install (or remove) ACPs in the host processor
• Connect (or disconnect) ACPs to ACIDPs in the CG
• Connect (or disconnect) CG-resident Internal DDTs to ACIDPs in the CG
• Activate an ACP (if ACIDP connection exists, only if installation mode is Test or
Restricted)
• Change an ACP program's mode (Normal, Restricted, Test, Not Installed)
• Examine the ACP Status Table
• Examine past ACP Installer Activity
• Set relative priority level of ACP
• Make ACP permanently memory-resident
After an ACP has been compiled and linked, this function is used to make the ACP known
to the host processor by adding its pathname to the ACP Status table. If the ACP has an
associated ACIDP, the installer sends the pathname to the ACIDP. This name is used by
both the host processor and the CG as the method for identifying which ACP is to be
affected.
The ACP Installer also is used to change an ACP's installation mode (among Normal,
Restricted, and Test) or to uninstall an ACP (both at the host processor and at the CG). It
is used to activate those ACPs without an ACIDP and those whose ACIDP is in Restricted
or Test state. The ACP Installer also provides commands to list or print the ACP status
table.
Any required ACIDPs can be built either before or after ACP compilation and linking;
however, they must be built before the ACP-to-ACIDP connection can be made.
3.2.3 ACP Status Table
The host processor's ACP Status table contains the following information on each installed
ACP:
• ACP name (and Task Group when activated)
• ACIDP name (if connection established)
• ACP installation mode (Not Installed, Normal, Test, Restricted)
• ACP execution state (Off, Run, Abort, Fail, Accessing)
• ACP Turn-on information
When its installation mode is Restricted or Test, any attempted parameter store by the ACP
to the LCN is stopped. The blocked data can be viewed by using the Data Table Viewer
program.
When its installation mode is Restricted or Test, an ACP will not be activated by periodic or
cyclic scheduling, but can be activated by operator demand, a Point Process Special, or
through the host processor terminal (through the Installer).
