Exit status always zero in KSH from Oracle Scheduler
Hi,
Running Oracle Scheduler 11g2 on an AIX 6.01.
I want to run a shell script (called "external program" in Oracle terminology) which executes some commands and react on the outcome using the exit status $?. For example a "cat thisfiledoesnotexist" and then get the $? which should be not zero. My script operates perfectly when ran from the command line, but when ran from Oracle Scheduler the $? is always zero...
My script has she-bang ksh
What is happening? Why is jobcc (see script below) always zero after exit13.sh finisched and ... can I work around this? I have looked for traps, coprocess, ...?
The main script called by Oracle Scheduler:
The exit13.sh:

Code is:

I'm preparing for exam and one of exams is to write own test command...
I wonder if in unix is a command which just returns exit code you specify..
I know I can easily write a function like this:
exStatus() {
return $1
}
-> my question is rather theoretical
thank you! (9 Replies)
Hi
Can someone help me please?
In a standard UNIX .ksh script, if you have the exit status..say 5...what line do you have to enter into the script for this number to be automatically converted to its actual exit reason by looking up the exit status file...wherever that is?
thanks

eval
exec(1) User Commands exec(1)NAME
exec, eval, source - shell built-in functions to execute other commands
SYNOPSIS
sh
exec [argument...]
eval [argument...]
csh
exec command
eval argument...
source [-h] name
ksh
*exec [arg...]
*eval [arg...]
DESCRIPTION
sh
The exec command specified by the arguments is executed in place of this shell without creating a new process. Input/output arguments may
appear and, if no other arguments are given, cause the shell input/output to be modified.
The arguments to the eval built-in are read as input to the shell and the resulting command(s) executed.
csh
exec executes command in place of the current shell, which terminates.
eval reads its arguments as input to the shell and executes the resulting command(s). This is usually used to execute commands generated as
the result of command or variable substitution.
source reads commands from name. source commands may be nested, but if they are nested too deeply the shell may run out of file descrip-
tors. An error in a sourced file at any level terminates all nested source commands.
-h Place commands from the file name on the history list without executing them.
ksh
With the exec built-in, if arg is given, the command specified by the arguments is executed in place of this shell without creating a new
process. Input/output arguments may appear and affect the current process. If no arguments are given the effect of this command is to mod-
ify file descriptors as prescribed by the input/output redirection list. In this case, any file descriptor numbers greater than 2 that are
opened with this mechanism are closed when invoking another program.
The arguments to eval are read as input to the shell and the resulting command(s) executed.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
EXIT STATUS
For ksh:
If command is not found, the exit status is 127. If command is found, but is not an executable utility, the exit status is 126. If a redi-
rection error occurs, the shell exits with a value in the range 1-125. Otherwise, exec returns a zero exit status.
