Logger is a PL/SQL logging and debugging framework. It’s used in many organizations to instrument code in their Oracle applications. Tyler Muth created Logger a few years ago and has since released several upgrades, the last being 1.4.0. After some great feedback, I’m pleased to announce that we’ve just launched Logger 2.0.0 Beta.
Instrumentation, logging and debugging utilities are essential in any PL/SQL development project.Comments Off | Filed in Oracle | Tags: framework, pl/sql
Tom is not not a fan of public synonyms, here is why:
- public synonyms pollute the namespace.
- public synonyms can lead to security issues.
- public synonyms can lead to a maintenance headache.
- public synonyms are public – no one owns them.
So, instead of public synonyms… Continue reading…2 Comments | Filed in Oracle | Tags: sql
If any of this is ticking boxes for you, it’s time to consider what flash could do for the performance of your database:Comments Off | Filed in Oracle | Tags: flash, storage
- I/O wait times are high. Essentially we are looking for high latency from the existing storage system. Flash memory systems should deliver I/O with sub-millisecond latency, so if you see an average latency of 8ms on random reads (db file sequential read), for example, you know there is potential for reducing latency to an eighth of its previous average value.
- I/O forms a significant percentage of Database Time. If I/O is only responsible for 5% of database time, no amount of lightening-fast flash is going to give you a big performance boost… your problems are elsewhere. On the other hand, if I/O is comprising a large portion of database time, you have lots of room for improvement.
You probably heard that Google is going to shut down Google Reader (GR) on July 1st, 2013.
With GR going away soon, I have been working over the past several days to detach it from OraNA.
Blogs that no longer exist have been deleted from the aggregator.
Blogs that still exist but have had no new posts since January 2012 are no longer aggregated by OraNA.
I was surprised at the number of blogs that fell into the two categories above.
The number of aggregated blogs fell from 508 to 323 (plus the blogs.oracle.com feed).
Here is a live list of all the blogs that OraNA aggregates.
I guess the enthusiasm for long form blogging has fizzled out over the years. Lazy bloggers (including yours truly) find it much easier and quicker to “micro” blog using Twitter, Facebook or Google+.
On a personal note, I have moved my daily dose intake of news from GR to Feedly.2 Comments | Filed in Oracle | Tags: aggregator, blog, Google
Have you installed or recently upgraded to Oracle APEX Listener 2.0? Have you used SQL Developer 3.2 to manage APEX Listener settings? If you answered yes to both questions then you are in for an unwelcome surprise.
The surprise is that you’ll get a “500 – Internal Server Error” whenever you upload a file via any of your APEX apps or import files via the APEX Application Builder.
Kris Rice responded to my tweet almost immediately.
The problem was a bug in the way SQL Developer uploads APEX Listener settings to the server.
This Oracle forum post describes how to reproduce the bug and the workaround to fix it.
Kris quickly put a fix together and checked it in for the next patch.
@eddieawad Fixed checked in for the patch.In the meantime, just remove that line in the config— krisrice (@krisrice) December 27, 2012
@eddieawad Now it’ll just put a log entry saying bad config param for anything non-numeric in that spot and ignore empty values— krisrice (@krisrice) December 27, 2012
If you are still hesitant to join Twitter, I hope that this post has given you an incentive to join this growing social network. Many Oracle employees, like Kris, are active on Twitter and listening to people like you and me who use their products on a daily basis.1 Comment | Filed in Oracle | Tags: apex, sql-developer
An external or internal application wants to send inbound data to your Oracle database, like for example a purchase order or a receivable invoice. You want to consume this data in real time.
The version of your Oracle database is 11gR2 or above. The only “tool” you have is the Oracle database, i.e. you do not have any middleware (like SOA suite) installed. The external or internal application can connect to your Oracle database.
The following is a fully functional example of the solution, starting from creating a new database user and ending with consuming the message in the database.Comments Off | Filed in Oracle | Tags: AQ, dbms_scheduler
Todd Trichler (@otnTodd) created a video montage of a bunch of Oracle ACE Directors. Ever wonder what an Oracle ACE Director is like? Check out the video below. I make an appearance at 4:02 minutes.Comments Off | Filed in Oracle | Tags: aced
