Hi

I would like to know what is dtexec process (/usr/dt/bin/dtexec) and which is its purpose.

Thanks

from "man dtexec"

DESCRIPTION
CDE uses the dtexec utility to execute COMMAND actions. In normal
usage, CDE automatically invokes dtexec when it is needed. CDE users
and administrators do not need to interact directly with dtexec.

The primary argument for dtexec is the name of a command to execute
and any command-line options or arguments for that command. There are
several important services that dtexec provides for the commands that
it executes. These services are controlled via the options specified
in the ``OPTIONS'' section in this document.

Hi,

Did you read 'man dtexec' ? Or you need deeper explanation ?

Regards.

I speak about dtexec because I have errorlog file under /home/oracle_user/.dt which is increasing "exponentially" --> /home is to 100%.

I have always the message :
Warning: Select failed; error code 9

This message could be written by dtexec process.
That's why i would like to have more information about dtexec and how to check if it is this process which is the cause of error message.

Hi,

Error 9 in hp-ux is "Bad File Number". Is the oracle user currently logged in using CDE ? If not, kill all dt processes belonging to this UID. Perhaps it could also be a problem related to maxfiles (maximum open files per user) which would prevent oracle user to open enough files for CDE.

Regards.

always from the man page:

APPLICATION USAGE
Normally, application programs do not directly invoke this program.
Normally, an application program links with the action service, which
then invokes dtexec as needed. Applications should use the waitTime
resource to configure the value of the -open_option and the DtexecPath
resource to configure the location of dtexec.

If cmd writes to stderr, the error messages are time stamped and
redirected to the user's errorlog file ($HOME/.dt/errorlog) when
open_option is 0. If open_option is set otherwise, the error messages
are typically displayed in the terminal window.



So the "Bad file number " may be originated from another program, associated with the DT desktop.
