terminals cannot be opened unless OSSTTY is also used. OSSTTY can be used to redirect one
or more OSS standard files to Guardian EDIT files or Guardian processes. See the osh(1)
reference page either online or in the Open System Services Shell and Utilities Reference
Manual for more information about starting OSSTTY with the OSH command and “OSSTTY”
(page 395) for more information about starting OSSTTY as a server.
• To the NetBatch product, the TACL OSH command is an executor program.
• Information generated by any periodic task should be appended to output files, so that each
execution of the task does not overwrite output from the prior execution.
• The general form of the TACL OSH command for batch execution of a program in the OSS
environment is:
OSH <- >>out_file 2>>err_file -p program_path program_args
<-
indicates that the OSS shell started by the command ignores its standard input (stdin) file.
>>
indicates that the OSS shell appends normal output to the identified file instead of the standard
output (stdout) file.
out_file
is the OSS pathname of the file to receive normal output.
If the initial working directory is not the current working directory, relative pathnames are
resolved from the initial working directory. When the initial working directory is a Guardian
subvolume and only a relative pathname is specified, the specified pathname must be a
Guardian file identifier and normal output is saved in a file-code-180 file in that subvolume.
2>>
indicates that the OSS shell appends exception output to the identified file instead of the
standard error (stderr) file.
err_file
is the OSS pathname of the file to receive exception output.
If the initial working directory is not the current working directory, relative pathnames are
resolved from the initial working directory. When the initial working directory is a Guardian
subvolume and only a relative pathname is specified, the specified pathname must be a
Guardian file identifier and exception output is saved in a file-code-180 file in that subvolume.
-p
explicitly runs a program file in the OSS environment. Note that -P (uppercase P) is not a valid
command option.
program_path
specifies the OSS pathname for the program to be run.
If the initial working directory is not the current working directory, relative pathnames are
resolved from the initial working directory. When the initial working directory is a Guardian
subvolume and only a relative pathname is specified, the specified pathname must be a
Guardian file identifier and the program file must reside in that subvolume.
