Multiple SQLPLUS background processes not working properly
Hi All,
I am running 25 background process from a Unix shell script which calls a single Oracle procedure with different paramenters each time.
These 25 process creates 25 different files.
When i run these 25 Background SQLPLUS processes, few files are not created completly but if i run 25 processes one-by-one then all 25 files are created properly with data.
My Doubt is :
1) Is there any restriction on number of SQLPLUS Background processes to run from script?
2) Are they affected by file size as size of files is in around 45K Bytes?
For info i am not using any Global temporary table for creating files.
Thanks

shell(1F) FMLI Commands shell(1F)
NAME
shell - run a command using shell
SYNOPSIS
shell command [command] ...
DESCRIPTION
The shell function concatenate its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise
/usr/bin/sh).
EXAMPLES
Example 1: A sample output of shell command.
Since the Form and Menu Language does not directly support background processing, the shell function can be used instead.
`shell "build prog > /dev/null &"`
If you want the user to continue to be able to interact with the application while the background job is running, the output of an exe-
cutable run by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to
save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing.
shell can also be used to execute a command that has the same name as an FMLI built-in function.
NOTES
The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local environments
will not be expanded by the shell because "local" means "local to the current process."
