ORA-12705: Cannot access NLS data files or invalid environment specified

Yesterday I got to "help" a colleague out with the aforementioned ORA-12705. I had never seen it before and there doesn't seem to be a whole lot of information out there, especially in regards to OBIEE.

Here's the definition from the docs:

Cause:
Either an attempt was made to issue an ALTER SESSION command with an invalid NLS parameter or value; or the environment variable(s) NLS_LANG, ORA_NLSxx, or ORACLE_HOME was incorrectly specified, therefore the NLS data files cannot be located.

Action:
Check the syntax of the ALTER SESSION command and the NLS parameter, correct the syntax and retry the statement, or specify the correct directory path/values in the environment variables.


This would occur when trying to import tables into the RPD (OBIEE). First thing that pops up is the Select Data Source screen:

select data source

Then this beauty would pop up:

ORA-12705

Ultimately the solution that, sort of worked, was here.

Windows - The NLS_LANG must be unset in the Windows registry (re-named is best). Look for the NLS_LANG subkey in the registry at \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE, and rename it.

We tried changing it to what I had in my registry: AMERICAN_AMERICA.WE8MSWIN1252

That didn't work.

Tried renaming it as the article suggested, that didn't work.

Finally, my colleague (without prompting from me), cleared the key (didn't delete, just blanked it)...and voila!

OBIEE: Parse NQQuery Log

It's been quite some time since I've dabbled in Java, thankfully JDeveloper makes it pretty easy for me.

I've been annoyed at how often I have to go dig through the NQQuery logs lately. Yes, I know about Session Manager and the ability to view logs there.

So I decided to write a quick and dirty java program that will pull the physical SQL out of the file. I believe there are 7 log levels in OBIEE, this is done at level 5 so no guarantee it will work on anything but 5.

I'll be putting the source code up soon and will update as appropriate. For the time being, here it is:
package oraclenerd;
import java.io.*;

public class ParseSQL
{
public static void main(String[] args)
{
ParseSQL run = new ParseSQL();
String query = new String();
int i = 0;
try
{
FileInputStream file = new FileInputStream( "/opt/projects/oraclenerd/classes/oraclenerd/test.log" );
DataInputStream in = new DataInputStream( file );
BufferedReader br = new BufferedReader( new InputStreamReader( in ) );
String strLine;
while ( ( strLine = br.readLine() ) != null )
{
if ( strLine.startsWith( "-------------------- Sending query" ) )
{
i = 1;
}
else if ( i == 1 )
{
if ( strLine.startsWith( "+++" ) )
{
System.out.println( "***************" );
System.out.println( query );
System.out.println( "***************" );
query = "";
i = 0;
}
else
query = query + "\r\n" + strLine;
}
}
in.close();
}
catch (Exception e)
{
System.err.println( "Error: " + e.getMessage() );
}
}
}
Obviously you'll need to change the path unless you have that exact path at home. You can find the log I used here.

There are 17 physical SQL statements in the log file. You should get 17 back.

The 17 SQL statements I retrieved are here (via console).

The source code is up above...until I get unlazy enough to put it under source control (Google Code). If you do make it pretty or add some functionality to it, please let me know, I'd love to include it.

OBIEE: Hillbilly RPD Source Control

No, this isn't a reference to @hillbillyToad.

During all the hullabaloo the other day and me fretting that I might have irrevocably destroyed the metadata, Frank Davis showed me a cool little trick.

In the Admin tool go the BMM layer, right click on the model you want and select "Duplicate with Presentation Catalog."

duplicate with presentation catalog

You'll then be prompted to name your new BMM and Presentation layer.

empty

Enter in the new names

empty

And you now have a copy of your BMM and Presentation layer

empty

What good is this you ask?

Well, it will allow you to do metadata development without affecting what any report writers are doing. It will also allow you to blow things up, quite easily if you wish, without major repercussions. That's nice to have.

OBIEE: Gotcha #4

Database Features

This may have been self inflicted, there is really no way to know. This is somewhat related to Gotcha #1.

The Problem

We kept tipping over the development database with only 10 or so people on it. The DBAs said we weren't including the date predicate on any of our tables. How could that be? (Quick aside, this problem is compounded; in that we have no summary tables and close to 2 billion records in the fact table). So instead of pulling back say, 100K records, we were pulling back 23 million. Yikes.

I started to pour through the query logs and confirmed that none of the physical SQL statements had any date predicates. Ouch.

But wait, reviewing the BI Server execution plan, the date filter was there...the catch was that the BI Server was filtering. Not good. The BI Server is not built to filter on some 23 million records. Most of us know that we should filter as much as possible, with Exadata pushing that concept down to storage.

Being responsible for the metadata, I naturally assumed this was somehow my doing.

So my colleague, Frank Davis, fired up a GoToMeeting session and we poured over the logs and anything we could find. We spent a few hours last night to no avail.

With a partial nights sleep, I began to use one of Frank's methods to further eliminate the offending table (possibly). Since it was the date predicate, I started with Time.

First, I pulled in Fiscal Year and created a filter for 2010. Ran the report, checked the log and the filter was in the physical SQL.

Next, Fiscal Week. Followed the same process, added the column, the filter and checked the log. It was there.

Finally, I brought over Calendar Day, created the filter, ran the report and checked the log. It wasn't there. WTF? I could see it in the execution plan, but not in the physical SQL.

Then Frank and I got back on a shared session and Frank had an idea...

The Solution

Frank wondered aloud about the database features, specifically, which were turned on.

If you aren't familiar with that, in the property section of the physical database, under the Features tab, you'll see the list of values, like this:

database features

See the ones I am pointing to? DATE_LITERAL_SUPPORTED? Yeah, that was turned off. Quite a few were turned off in fact. Frank found the guide for setting up the features on our particular database (Neoview) and we went through and turned everything on that was recommended.

I reran my small test and voila! The date predicates were being pushed to the database. Ran some of the other offending reports and verified that they too were passing the date predicates.

I don't know if I somehow reset the database features or if someone else did. I'll never know in fact (yes, bigger problem). Thankfully it was only in a development environment so the impact was minimal.

(NOT) SOFA KING COOL

sofa king cool!
Some time back, my wife bought me one of those Sofa King Cool t-shirts.

I typically wear it around the house or as an undershirt, so I can do the Superman-ripping-his-shirt-open thing and impress my friends and colleagues.

Impress might be the wrong word...anyway.

I also wear it to work out, well, run (walk). I did so tonight.

It was dusk, 9ish, and I was running against traffic (on the sidewalk) in my neighborhood. As a car approached, I took my eyes off the ground to observe the car...when I tripped, fell on my hands and rolled over. Like an idiot.

Not like the Sofa King Cool dude...at all. I wish I had a picture then I could start a website of people wearing "cool" clothes and doing something completely stupid.

Why I Love Email

This has been on my mind for...a long time. It was accelerated by John Piwowar's sharing of this article on Coding Horror about voice recognition.

Mr. Famous Piwowar

I could really care less about voice recognition, the thing that I got from the article, is that most people understand the written word better than the spoken word. In particular, this passage hit home:

In my experience, speech is one of the least effective, inefficient forms of communicating with other human beings. By that, I mean...
  • typical spoken communication tends to be off-the-cuff and ad-hoc. Unless you're extremely disciplined, on average you will be unclear, rambling, and excessively verbose.
  • people tend to hear about half of what you say at any given time. If you're lucky.
  • spoken communication puts a highly disproportionate burden on the listener. Compare the time it takes to process a voicemail versus the time it takes to read an email.
Say it again!

One of my colleagues is super-bright, Ivy league educated...but I don't understand a word he's saying sometimes. We do joke back and forth that it's my measly state school education holding me back, but it is a real problem, for me. I've been working with him so that we can meet somewhere in between, but it's difficult. He uses a lot of 3 syllable words and my brain just can't handle that.

When he writes, it's better...but there's still a gap. I won't blame him for all of it. :)

I've had the problem in the past...one of my former Arch Nemesis(es?) sat right next to me, but could barely speak a word of English (no, it's not what you think). The running joke in the company was that this person had their own special brand of English (not American English either). The writing however, was slightly better.

It's not just limited to email either, IM will suffice since you can save that stuff and read it again later.

It's also not a CYA (cover your ass) thing...it's just that, well, people don't communicate very well. I'm probably guilty of this as well. I am not extremely disciplined (in spoken word) and I have a tendency to go (way) off topic (like telling dirty jokes). Email/IM are perfect.

There's also the added (CYA) bonus of having it there to digest later, perhaps multiple times, which I often do. I'll flag a particular important email and reread it 10s of times.

Is this unacceptable to you? Should you be able to come up to me and just say, hey Chet, I need such and such, and assume you are done with it?

SOUG: APEX 4.0

The much anticipated APEX 4.0 release is coming soon...in that spirit, Dan McGhan [blog|twitter] will be presenting on the new features. You might remember Dan, he's the one that constantly interrupted me during my first presentation ever, on APEX. We followed that up with a "joint" (by joint I mean I "let" him do all the work) presentation a few months later.

The event goes from 6 until 8 with the first half hour dedicated to eating and greeting. From 6:30 to 8 will be Dan's presentation.

You can read the event details here. Or I can just put it all here to save you a click (you're welcome):

Dan McGhan, our resident APEX expert, will be bringing us up to speed on the recent new release of Oracle's Application Express. APEX 4.0 is expected to be the biggest release in the product's history.

This session will break down many of the exciting new features that everyone has been looking forward to, including Websheets, Dynamic Actions, and Plug-ins, just to name a few. With APEX 4.0, development should be faster and easier than ever.

Dan McGhan has been a long time member of the SOUG. Dan is an Oracle Application Express expert and advocate. In addition to his "day job" with SkillBuilders.com, he is one of the top 10 contributors to the APEX forum, maintains his own Oracle and APEX blog, and has been a speaker at the New York Oracle Users Group, New England Oracle Users Group, and Suncoast Oracle Users Group events.

Exadata Learning Resources

In a year or 2, this will be worthless as everyone will probably be sitting atop Exadata, aka the Oracle Database Machine (ODM), aka Oracle Exadata Storage Server.

Here's a list of some resources (mostly, ok, all blogs) if you're interested in reading up.

I found Glenn's blog through the OraNa feed recently, specifically the Open Storage S7000 with Exadata… a good fit ETL/ELT operations. post.

I don't think he's quite transitioned all of his articles from his Sun site, so you can find some Exadata articles there. His new site is hosted on Wordpress.

Kerry Osborne [linkedin]
Occupation: CIO at Enkitec

I've read Kerry's blog previously, just missed him. Thanks to the famous John Piwowar [blog|twitter] for reminding me.

End User Response Time

Inspired by Robin's [blog|twitter] Measuring real user response times for OBIEE, I remembered a wonderful APEX nugget: DEBUG

Robin's post was the continuation of a discussion between himself and Alex Gorbachev [blog|twitter] about...something. I'm pretty sure I glossed over much of it.

The reason I glossed over it is because I immediately thought about APEX and how easy it was to measure end user response time. OK, a little fib there, the data is there, some enterprising young APEX developer would just need to figure out how to get it.

OBIEE has cruddy instrumentation...wait, no instrumentation, from an end-user perspective.

But APEX does. (BTW, we should lobby to get some from the APEX team to show the OBIEE team how they do it).

That's just the header section.

Now OBIEE can fire off multiple queries for a single report and for that you would probably use the built-in Usage Tracking data...but you still wouldn't have a end-user experience there.

I created a simple APEX page with two reports. One is querying a 10 record table and the other is querying a copy of DBA_OBJECTS.

Check out the instrumentation surrounding the region:

region 1

That's the small table and it's pretty quick.

Now let's look at the big table:

region 2

You might be able to see up at the top of that last image, the 0.13 IR:Binding...then the 0.17: Printing rows

That'll give you an idea of how long each region takes to run (0.04) which would help you to identify slow parts of your web page. I've used this in the past and it's very nice.

Finally, you have the footer section:
 0.17: Computation point: AFTER_FOOTER
0.17: Processing point: AFTER_FOOTER
0.17: Log Activity:
0.18: Execute Count=0
0.18: End Show:
Basically, the page took 0.18 seconds to load. Start capturing that data (i.e. snapshot), make your changes and then re-evaluate. Alex put it very nicely in the comments:
In this case, it’s a project of migrating from one platform to another. While load simulation provides results (and that’s been done), end users experience (response time) is the only thing that counts.

Without measuring it, users have full control on how they relay their experience to you and there is nothing you can prove or disprove.

Measuring it gives all the answer (and lots of power!).

OBIEE: Gotcha #3

I received this wonderfully informative error this evening:

Promotion of checkout lock on Value to exclusive failed.

Value[nQSError: 36006] Promotion of checkout lock on Value to exclusive failed.

Lacking an Oracle Support login...I ventured to Google. Just like the error, it was wonderfully uninformative.

Log files?

Nothing.

This halted all development for me. Not all, I could make one change, check it in (save) and then I would get that error again. Wonderful.

From what I could piece together, and this is the purest form of speculation, it had something to do with naming.

I had a Physical database named "LOV"
I had a couple of columns (different tables) in another database with the same name.
These were all combined into one subject area.
Therefore that had to be the issue.

Or not. Who knows?

How did I fix it?

Shutdown the BI Server, opened up the RPD in read-only mode, did what I had to do and saved it...no error. Sweet.

Fired up the BI Server, opened up the RPD...you can only open this in read-only mode. WTF?

Let's try this again.

Shutdown.

Start.

Login. Success!

I almost followed the universal Windows rule of rebooting 3 times...almost.

Thank You?

More of a rant than anything.

I once teamed up with a co-worker to collect all the crazy-long email signatures people use. I think the longest we ever collected was around 10 lines, complete with pictures (a logo) and an alphabet soup of titles earned. Email address was included...which I still have a hard time figuring out why. Perhaps someone will print it? I guess those people still exist.

Anyway, the other day I noticed this (not the first time, just the first time I thought to write about it...plus, I have nothing else useful to say so maybe this will clear the bit of block I am having right now).
Thank You,

First Name Last Name
Title
Phone Number(s)
Thank You? Is that just to save time and keystrokes as Sten Vesterli [twitter|blog] notes:

Sten Vesterli

I understand the efficiency part...but what if there is no actual "Thanks" required? Just seems a bit...weird to me.

I will end my email communiques with one of the following:
* Thanks
* Regards (probably a UK influence there)
* Sincerely

With my name, "chet" following a couple of lines below.

It's not that much extra typing, for me. I'm in the 70 WPM range...and maybe that's where the difference is. Who knows?

Just needed to get this off the chest.
