Home -> Community -> Usenet -> c.d.o.server -> Re: How to tell if Oracle is ready?
My thank yous to those who gave suggestions. After testing on my system I have decided that a combination of
ps -eaf | grep ora_d001_$ORACLE_SID | grep -v grep > /dev/null
and when grep returns 0 I follow up with
# * From: jstrange_at_imtn.dsccc.com (John Strange)
# * Newsgroups: comp.databases.oracle.server #
sqlplus <<'EOF' > /dev/null
/
set pause off
set pause off
set pause off
set pause off
set pause off
set pause off
exit 5
EOF
if [ $? != 5 ]
then
....
successfully determines if Oracle is up AND ready to work.
And on top of that I learned what a 'here document' is (quite neat, actually).
