Re: all time worst question I have been ever asked as a DBA

I would argue that be it private or public sector there is no reason on any 
level that these things can not exist. Certainly, if you are coming in as a 
contractor and have a specific job to do, then it's a more difficult proposition 
and you might need to resort to other communication to get the job done. I also 
grant you that, in the end, sometimes damagement just says they don't care and 
just do and you have to do.... so I'm not breathing rarefied air here. Still I 
think that we tend to be a little bit sheep like sometimes,

:) I love this old campy series....

avoiding arguments or debate for a number of reasons. We need backbone and 
better yet, learn to teach and communicate without being combative.

Not when it's a city government employee making the statements.  Did I forget

This get's into some of the things I talk about in my blog of late, like 
communication. The real problem here and the solution is not an argument or 
letting things fail, but it's rather stated SLA's and RPO's defined and agreed 
to by all. With these in place we change the conversation like this:


Them: "I've been reading and exports take up less space than backups, so we'll 
do those instead.  Oh, and shut off this archivelog stuff, that will save disk 
space."
Me: "You can't do point-in-time recovery if I shut off archive logging and only 
perform exports. Using exports will violate our standards, the SLA's established 
for this application and will also violate the standard RPO. If you want that 
done, you need to take this through the exception and change control process"
Them: "All that work just to get around standards?"
Me: "Yup. Want me to give you the change request form?"
Them: "Um... no, thanks."
This will stop a lot of these stupid conversations in their tracks. When people 
realize that they will have to go through a formal process to change a 
standardized practice and justify it, they usually will back down unless it has 
real meaning and importance. SLA's, standards and the like are leverage to be 
used like a big bad hammer. 


My 2 cents....

Back to the original topic -- it wasn't a question so much as a statement:
 
Them: "I've been reading and exports take up less space than backups, so we'll 
do those instead.  Oh, and shut off this archivelog stuff, that will save disk 
space."
Me: "You can't do point-in-time recovery if I shut off archive logging and only 
perform exports."
Them: "Why not?  You do the export at the end of the day and we're good."
Me: "That won't capture batch-processed data."
Them: "We can rerun the batch.  Do as I ask."
 
I did.  Several weeks later a hardware failure lost the database and they 
could only restore from the most recent export and, as expected, the batch jobs 
needed to be rerun and all user transactions  had to be re-entered.  The RCA 
revealed the above conversation.  You can guess who remained and who didn't.

BTW 

I also never use those file extensions anymore, but then again DBCA still has 
that practice and I would not be surprised if it turned up in OCP manuals etc.
I once created an enhancement request saying that "this new APEX core directory, 
regarding naming is probably not a good idea to implement". 
They didn't get the point, or I didn't got my point across, that old unix admin 
methods / people (maybe still also on linux nowadays) have a practice to delete 
from time to time core files and core directories on their filesystems…

Which is the #1 reason I no longer allow redo logs to end in ‘.log’! J
 
I have that as a check implemented in a procedure that runs each night to ensure 
every database in our environment complies with a few standards that I don’t 
consider to be debatable.

Be happy that he asked. Sometimes they just delete log files because they need 
the space.

Onderwerp: all time worst question I have been ever asked as a DBA
So, I am getting this error on one of our virtual Linux servers:

ORA-00210: cannot open the specified control file
ORA-00202: control file: '/u01/app/oracle/datafiles/devdb/control01.ctl'
ORA-27086: unable to lock file - already in use

Its probably due to a stale NFS lock.  The question from my sys admin:
-rw-r----- 1 oracle oinstall 10076160 Jul 22 13:33 control01.ctl
can that file just be removed



Ok, I am a little frustrated with him...
