Fallback
After fallback, the new configuration attribute would not be recognized, and the feature
would not work.
OSS System Utilities
The OSS gtacl command has been enhanced to add two optional flags to its
command line. These flags enable more control over the conversion of OSS
environment variables to Guardian environment PARAMs when the gtacl command
is used to run a program or command using TACL:
•
-s
Suppresses all variable conversions to PARAMs; this flag takes precedence over
the -f flag.
•
-f pathname
Restricts conversion to those OSS environment variables described in the named
OSS file. This file is not subject to the buffer size restriction on the number of
variables that can be converted when the default conversion is used.
If both flags are omitted, there is no change in conversion behavior from that provided
in previous versions of the gtacl command.
Note. OSS persistent processes are supported on G06.23 and later RVUs; however, the
above SPRs are not on the G06.23 SUT, and T8624G10AAM and T8397G00ABA are not on
the G06.24 SUT. All of the listed SPRs are included on the G06.25 and later SUTs.
OSS persistent processes can be used without SPRs T8624G10AAM and T8397G00ABA. If
those SPRs are not installed, some OSS applications might fail at processor startup unless
modified to include an initial delay (on the order of 10 seconds). This delay is not needed when
those SPRs are installed.
Without T8624G10AAM and T8397G00ABA, when an OSS shell is launched immediately after
a processor comes up, the shell needs to wait until processor components of the OSS
environment such as the OSS pipe server finish initialization. The necessary delay can be
achieved by adding an OSS sleep 10 command either to the STARTUPMSG attribute or as
the first entry in the script launched by the STARTUPMSG attribute.
See the sleep(1) reference page either online or in the Open System Services Shell and
Utilities Reference Manual for more information about the sleep command.
