If the job is no longer associated with a pseudo-terminal then (as far as I know) it cannot be re-attached from outside the process.
Is the process "1" the ultimate parent of the group of tasks?
No, it is still associated with a pseudo-terminal - I'm just wondering how I can set that pseudo-terminal as the active one for my session. Here is one process that was active when the network went down:

So if a 2-node cluster runs in active-active mode (and the same application), what is the benefit of using HACMP ?
If it runs in active-stanby, it is easy to... (9 Replies)

pty
PTY(4) BSD Kernel Interfaces Manual PTY(4)NAME
pty -- BSD-style compatibility pseudo-terminal driver
SYNOPSIS
device pty
DESCRIPTION
The pty driver provides support for the traditional BSD naming scheme that was used for accessing pseudo-terminals. When the device
/dev/ptyXX is being opened, a new terminal shall be created with the pts(4) driver. A device node for this terminal shall be created, which
has the name /dev/ttyXX.
New code should not try to allocate pseudo-terminals using this interface. It is only provided for compatibility with older C libraries that
tried to open such devices when posix_openpt(2) was being called.
FILES
The BSD-style compatibility pseudo-terminal driver uses the following device names:
/dev/pty[l-sL-S][0-9a-v] Pseudo-terminal master devices.
/dev/tty[l-sL-S][0-9a-v] Pseudo-terminal slave devices.
DIAGNOSTICS
None.
SEE ALSO posix_openpt(2), pts(4), tty(4)HISTORY
A pseudo-terminal driver appeared in 4.2BSD.
BUGS
Unlike previous implementations, the master slave device nodes are destroyed when the PTY becomes unused. A call to stat(2) on a nonexistent
master device will already cause a new master device node to be created. The master device can only be destroyed by opening and closing it.
The pty driver cannot be unloaded, because it cannot determine if it is being used.
