TS/MP 2.5 Release Supplement

the existing PATHCOM interface where all the existing PATHCOM commands are supported.
However, unlike the existing PATHCOM interface, PDMI has the capability to communicate to
multiple PATHMON processes simultaneously so that the same set of PATHCOM commands are
run for multiple PATHMON processes.
For more information, see “Introduction to PDMCOM” (page 38).
ACSCTL File Configuration
The ACSCTL is a configuration file that defines constraints to the namespace used by the ACS
subsystem. The file defines the associated PATHMON environments that comprise a Pathway
domain. The following three sections must be defined in the ACSCTL file: ACS Domain, Pathway
Domain, and Owner Membership.
ACS Domain Section
The ACS Domain section defines the ACS domain used for the current NonStop system. The ACS
domain is used only for a consistency check for the validity of the ACSCTL file. The ACS domain
name mentioned in this section must match the ACS domain name provided in the ADD ACS
command through the SCF interface. Otherwise, this is treated as an error condition and the state
of the ACSCTL file becomes inactive.
Pathway Domain Section
The Pathway Domain section identifies a set of PATHMON processes that can be used to obtain
links to server classes. The set of PATHMON processes is called the Pathway domain. The
PATHMON processes must run on the same NonStop system.
Owner Membership Section
The Owner Membership section identifies a set of Pathway domains for which the user is the owner.
The ACS core processes are open to PATHMON processes and use owner membership information.
If a particular PATHMON’s process access ID (PAID) does not match the user specified ID in the
owner membership section, the PATHMON is not used in the domain. A Pathway domain can
occur only once in the owner membership section. Multiple users can own a Pathway domain to
match the user name template (group-name. member-name) as specified by the owner
membership.
NOTE: The ACSCTL filename must not be more than seven characters.
ACSCTL Configuration File Syntax
The ACSCTL file is a standard edit file using the following syntax definitions:
<file> = {[[<comment><eol>]&]<adsection><pdsection><osection>}
The syntax definition of the ACSCTL file sections is explained below:
<comment> = {#{any printable character}&}
<eol> = {?\n?}
<adsection> = {<sp>[ACS Domain]<sp><eol>[[<pline>]&]}
<pdsection> = {<sp>[Pathway Domain]<sp><eol>[[<dline>]&]}
<osection> = {<sp>[Owner Membership]<sp><eol>[[<oline>]&]}
<sp> = {{? ?|?\t?|NULL}&}
<pline> = {<adname>]<sp>=<sp><system>}
<dline> = {<pdname>]<sp>=<sp><PATHMON><sp>}
<oline> = {<owner><sp>=<sp><pdname>[,<sp><pdname>[,&]<sp>]<eol>}
<adname> = {ACS domain name}
<system> = {\{Valid NonStop system name on EXPAND network}}
