Home -> Community -> Mailing Lists -> Oracle-L -> RE: Database Link Timer
DBMS_ALERT springs to mind
How about
register an interest in an Alert=20
submit a job to run in 10 secs that raises the afore mentioned alert
start the sql "ping"
unregister the interest in the Alert
the exception being to handle the alert raised by the job

PL/SQL does not have signals.
If you wrote this in a language that was more suited to systems programming, such as oh, say, Perl, this would be easy.
And no, I am not being facetious.=20
PL/SQL is not an appropriate tool for this kind of work.
You may be able to do this in Java, but I don't know.
