Question { Oracle, 13776 }

what is jumbi process?

Answer

A zombie process or defunct process is a process that
has completed execution but still has an entry in the
process table.
When a process ends, all of the memory and
resources associated with it are deallocated so they can be
used by other processes. However, the process's entry in
the process table remains. The parent can read the child's
exit status by executing the wait system call, at which
stage the zombie is removed. The wait call may be
executed in sequential code, but it is commonly executed in
a handler for the SIGCHLD signal, which the parent
receives whenever a child has died.After the zombie is
removed, its process ID and entry in the process table can
then be reused. However, if a parent fails to call
wait, the zombie will be left in the process table.
Answer
# Do a ps and identify the zombie processes
# ps -el | grep 'Z'
Occasionally, these processes are in such a state
that the
only way to get rid of them is to reboot to clear
them.

In most cases, you can get rid of a zombie by
normal means,
"kill -15 zombie PPID", "kill -9 zombie PPID".

It is a situation in which both links are down in a cluster
set up.
Split brain can be resolved by joepardy or io fencing
method.

In joepardy one of the link will be down and it will cause
the mebership in jeopardy but will maintain the
commmunication in single like. But you acn act before a
failover:-)
