Re: Apache::DBI and altered packages
Geoff, I'm going to make a non-technical suggestion: You need to have change control implemented so that packages in your database are not changing during business hours. If you are 24x7, then you need to schedule an outage, and notify your customers of scheduled downtime. This is more of a management and logistics problem than a Perl or Apache or Oracle problem On Fri, 22 Dec 2000, Geoffrey Young wrote: > I was wondering if anyone has found a good way around persistent connections > and package recompiles.

RE: Apache::DBI and altered packages
So how exactly would you "check" a package. Would you have to call a stored procedure in the package? Or would merely accessing a package variable be enough? -Paul > -Original Message- > From: Geoffrey Young [mailto:[EMAIL PROTECTED]] > Sent: Friday, December 22, 2000 12:03 PM > To: 'Perrin Harkins'; [EMAIL PROTECTED] > Cc: [EMAIL PROTECTED] > Subject: RE: Apache::DBI and altered packages > > > > > > -Original Message- > > From: Perrin Harkins [mailto:[EMAIL PROTECTED]] > > Sent: Friday, December 22, 2000 11:55 AM > > To: Geoffrey Young; [EMAIL PROTECTED] > > Cc: [EMAIL PROTECTED] > > Subject: Re: Apache::DBI and altered packages > > > > > > > > If you change the ping() method to check whether or not your > > package still > > works, Apache::DBI will automatically get a new connection > > when it fails. > > yeah, that's an idea - lots of packages to check, though. > but this might be > the best solution... > > thanks > > --Geoff > > > > > - Perrin > > >

If you change the ping() method to check whether or not your package still works, Apache::DBI will automatically get a new connection when it fails. - Perrin
Apache::DBI and altered packages
hi all... I was wondering if anyone has found a good way around persistent connections and package recompiles. With Apache::DBI, on occasion when someone recompiles a package and doesn't tell me, I see ORA-04061: existing state of package body "FOO.BAR" has been invalidated ORA-04065: not executed, altered or dropped package body "FOO.BAR" ORA-06508: PL/SQL: could not find program unit being called my Oracle gurus here tell me that whenever a package changes any open connections will get this error. Since the connection itself ok (just not the stuff I need to use) the only solution currently available seems to be $r->child_terminate() so that at least that child doesn't barf every time. However, this leaves the current request in a lurch... I was thinking that maybe something like Apache::DBI::reconnect() was needed - call DBI->disconnect then DBI->connect again. that is unless someone has dealt with this in another way - someone mentioned that perhaps the proper ALTER OBJECT permissions would force a recompile - I dunno... --Geoff
