Re: Email from PL/SQL with Java - UTL_SMTP - UTL_TCP

Since I'm addicted to email notices, I configured my own instance with the UTL_SMTP package. I wrote some "wrapper" PL/SQL so that I can invoke a procedure & pass in three arguments; sender_name, recipient_list, & message (a text string). On my 8i instances I created DB triggers to send email messages upon startup & shutdown. On the V7 instances within the Unix scripts I invoke SQL*PLUS which runs a PL/SQL procedure that passes the same three arguments to MY V8.1.6 instance. Therefore all my DB's send me a message when they transistion state. All was done in PL/SQL; & no JAVA. In other words, I have a single DB that handles the SMTP interface for all the other DBs I support.

My message length is limited to the maximum length of a single VARCHAR2 variable in PL/SQL, but it satisfies my needs so far.
