Spoiler

Here’s a little detail I could do without in my database:



select
       owner, object_type, object_name
from
        all_objects
where
        object_name like '_'
order by
        object_name, object_type
;

OWNER           OBJECT_TYPE         OBJECT_NAME
--------------- ------------------- --------------------
APEX_030200     PROCEDURE           F
PUBLIC          SYNONYM             F
APEX_030200     PROCEDURE           G
APEX_030200     PROCEDURE           P
PUBLIC          SYNONYM             P
APEX_030200     FUNCTION            V
PUBLIC          SYNONYM             V
APEX_030200     PROCEDURE           Z
PUBLIC          SYNONYM             Z

Public names like P and F for procedures or functions are just not on (unless I create them myself).

Analyzing IO at the Cell level with cellcli… a new and improved script

Recently I had the pleasure of corresponding with Hans-Peter Sloot.  After looking at my simple tool in this post to gather cell IO data from cellcli, he took it a several steps further and created a nice python version that goes to the next level to pull IO statistics from the cells.

current_rw_rq.py

This script provides breaks down the IO by “Small” and “Large” as is commonly done by the Enterprise manager.  It also provides a summary by cell.  Here is a sample output from this script.

If you’re not using hugepages, you’re doing it wrong!

Well, there’s been a bit of a delay in with my planned testing of dbVisit Replicate and Oracle GoldenGate for zero-downtime upgrades. So, I’ll be (hopefully) getting back to that within a couple of weeks.

Meanwhile, I recently ran across a discussion on the Oracle OTN Community forums, asking about performance and hugepages configuration, here in the Oracle Database – General Questions Forum.

I think my answer bears repeating, so, here is a slightly modified version:

First, I’m going to take a strong position on hugepages. I’m going to go as far as to say, for any non-trivial SGA size, if you’re not using hugepages, you’re doing it wrong. There are three main points to consider.

Fedora 20 : Upgrade from Fedora 19

It’s a little over a month since Fedora 20 was released, but during a terrible bout of insomnia last night I decided to upgrade my desktop PC.

The upgrades using “fedup” worked fine for the previous releases (Fedora 18, Fedora 19). Unfortunately, it failed abysmally for the upgrade to Fedora 20. I tried a few times, but I was not able to troubleshoot it, so I gave up and did a reinstall.

I’ve got an SSD for the system drive, but keep almost everything of importance on a second drive (and a backup drive). I tend to do most things in VMs, so I ended up doing the following:

OUGN Vårseminar 2014

I’ve had some papers selected for the OUGN Vårseminar 2014 event in April, so I will be there representing OTN and the Oracle ACE Program. There is an impressive array of speakers lined up for this event already. Should be fun!

I’ve got a couple of months to practice my Captain Jack Sparrow impression. I wouldn’t want to look out of place on the boat!

Cheers

Speed up Import with TRANSFORM=DISABLE_ARCHIVE_LOGGING in #Oracle 12c

A very useful 12c New Feature is the option to suppress the generation of redo during Data Pump import. I was talking about it during my recent 12c New Features class in Finland and like to share that info with the Oracle Community here. My usual demo user ADAM owned a table named BIG with one index on it. Both were in LOGGING mode when I exported them. The Data Pump export did not use any 12c New Feature and is not shown therefore.

OTN Yathra 2014 : See you there!

In November I wrote a post about my possible inclusion in the OTN Yathra 2014 tour. That has been confirmed now, so I’m representing OTN and the Oracle ACE Program at all the cities in the tour.
