Uh-oh. A blog post ...

by Lazy Lurker In reply to The Blog of a Lazy Lurker

I will get to being lazy a some point soon.  I promise.<br />
<br />
So what to I do?  I am an Oracle DBA.  Mostly, I have been
relegated to the realms of physical and support work.  I got
dragged there --kicking and screaming -- about six years ago.  All
the application design work I loved was ripped from my grasp. 
Begging and pleading got me a lot of empty promises, but here I
remain.  Why?  Why must I here and manage this end of the
databases and instance?<br />
<br />
Because I'm good at it.<br />
<br />
Damn.  Shot in the foot by competence yet again.<br />
<br />
<br />
Well, perhaps I can share something with you that SOMEONE can use.<br />

Locking madness

by Lazy Lurker In reply to The Blog of a Lazy Lurker

OK, what gives today?  I actually had to fix a  major
production issue.  That makes two (or maybe three) this
month!  Somebody is playing with my karma over here.<br />
<br />
It was actually pretty simple.  Citrix-deployed app lost contact
with the user but did not clean up.  So a phantom session was
sitting holding a lock.  The tricky part was wading through the
pile of queued up requests to find the locking session.<br />
<br />
It would be a snap -- except for an outstanding bug in my
version.  An old favourite script does not work in this version
because when I try to join multiple copies of V$LOCK, I get
locked!  Major bummer.<br />
<br />
Fortunately, I reworked the script months ago.  I select
everything from the views into a temporary table first, then work with
that.  The bug does not get in my way; I get my answer faster than
I can notice the lag.<br />
<br />
A few judicious "alter system kill session" commands and I get moved a
few places away from the top of the "Who to fire next?" list.<br />
<br />
<br />
I will post the script if the following can be done:<br />
<br />
1) I can find a place to put it<br />
2) I can figure out how to put it there<br />
3) I can be bothered to try (hey, I'm lazy, remember)<br />
<br />
<br />
