About fragmentation of Oracle

Environment : Windows2003 Enter, Oracle10g
If disk defrag of Operation System have enforced.
Be fragmentation of Oracle resolved???
Edited by: user10821817 on 2009. 4. 20 오후 7:58

OS Fragmentation is different thing and oracle fragmentation is different. OS fragmentation is for OS internals and its working to get better disk i/o and minimize user/service response; while in oracle if you are using locally managed tablespace (LMT) it provides you autometically coalesce.
Coalesce creates a big free extent by taking space from free extents and it is used in dictionary managed tablespaces (DMT); while if you use LMT it works autometically; we do'nt need to alter tablespace <tablespace name> coalesce;
So best is use LMT and move all objects from DMT to LMT i.e. alter table/index <object name> move tablespace <new LMT name>; or get object names from user_objects.

Question about Communication with Oracle 7

Hi,
Generally we use Oracle Snapshots for Communication, but since Oracle 9.2.0.5 do not work with Oracle 7.1.5.2.4. we are thinking about do use Oracle Interconnect for this Link.
Now I have the following two Questions about Communication with Oracle 7:
1. Is an Adapter for Oracle 7.1.5.2.4 available?
2. From your experience, does it make sense to install Oracle Interconnect for implementation of only one read only Link with 3 Tables if an OAS for BI is available?
Thanks,
Hannes

1. The Oracle database adapter is for Oracle 8i and up. I checked the code needed in the database and doubt that will work in Oracle 7.
1. The other option Advanced Queuing also needs 8i and up.
2. For me it doesnt make sense that you want to connect to Oracle 7. Oracle 7 is unsupported and should not have to be developed against. Also the license costs for Oracle Interconnect ~17K without any discount is a bit steep for read only links to three tables. Having the OAS means you wont have to pay another additional ~17K for the apps server.

Doubtful about security of oracle's Wrap code!

Dears
I am little bit doubtful about security of oracle's own Wrap code like package "sys.utl_smtp" .
Someone can easily Unwrap it without source code?
How it possible? whats your opinion about this? please can anybody clear me.
Regards
Abdul Halim
Edited by: Abdul Halim on May 31, 2013 8:14 PM

Halm, you are operating under the mistaken belief that your code deserves hiding from the customer and competitors to begin with. Why? All you are doing in the code is performing DML. It is not like your application is the only one in the world that performs its function.
If someone really wanted to they could figure out what your code is basically doing just by looking at the table and file data before and after running the code. By careful manipulation of the data and studying the results they can figure out what is being done and then develop their own specific of the how it is done. One can also look at Oracle's internals as the code is being processed both using Oracle provided views and direct peaking at Oracle's shared memory. Then there are tools like sql trace which will captute the SQL, waits, and binds for the process.
But all of this is kind of mute in that most shops do not have the talent to write their own unwrapper nor has the shop purchased an unwrapper so if you wrap the code it is going to be secured from most users and competitiors. I would just recommend that potential customers not purchase your product becuase the customer is going to need access to the code either for debugging (bugs will exist in the code) or tuning. Likely both.

Attention! About problems with Oracle 8.1.6 on newer Linux distributions!!

Hello all, I've just got some feedback from a helful person at http://www.crunge.com/ about the problems concerning RedHat Linux 7.0 and Oracle 8.1.6, this MAY apply to other newer linux distributions.
I've tried, without luck, to install Oracle on RedHat 7.0 and Slackware 7 (the newest one), and it would not install properly, kept stopping right about when the database initialization started at 80% finished install procedure. Sp i wrote them a mail, not expecting an answer really, but I did got an answer, and below is what the person said;
Thanks for the feedback.
Oracle 8.1.6 does not work under Red Hat Linux 7. Yes, that's the problem
that I mentioned in the doc--you get to 80% and the DBCA crashes and the
Oracle executables die.
I've heard, but I haven't tried it myself, that if you install the latest
glibc errata (2.1.94) then the DBCA completes but the Oracle executables
still die. The DBCA problem was apparently a Java issue that is fixed in
the errata. But you're still out of luck since the exes won't work.
It might appear that this is a problem with Red Hat Linux 7. But it appears
that it is a problem with some assumptions that Oracle made, assumptions
that worked with glibc 2.1.3 (the C library included with RHL 6.2) but which
prove false with later glibc versions. As other Linux distributions adopt
the new glibc Oracle will fail to work on them as well.
The best advice I can give at this point is to install and run Oracle on
Red Hat Linux 6.2. Hopefully Oracle will address the glibc issues with the
8.1.7 release.
Chris
p.s. Do not construe this
as an official Red Hat response; I merely forwarded your e-mail from my
home account. This response and the web pages I put up are mine.
So i guess one sollution to the problem is to try a bit older version of the linux you are having problems with (i tried it on RH 6.1 and it worked like a dream).
Another solution can be to wait it out to check and see if Oracle put a fix out here on technet...?
Hope this helps people bogged down in fustration.

Hey all. Just to let you know that it is entierly possible to get Oracle to install under RedHat 7 and run happily. I have done it on two differenct machines. There is a bit of fooling with glibc to get it to work. However after you do that it works like a dream. VALinux has a work around posted at: http://ftp.valinux.com/pub/support/hjl/glibc/sdk/2.1/
The READEME.Oracle8i has the work around and the two tar balls are the necessary files. I followed the directions to the letter and they worked like a dream. Any questions feel free to drop me a line.
Cheers,
Graham<HR></BLOCKQUOTE>
OK, so i followed your instructions to the letter (several times), sure I get past the 80% bug but now I have new erros coming up , -"Error in invoking target install of makefile /usr/oracle/sqlplus/lib/ins_sqlplus.mk". I get a whole series of these errors for various mk files. These errors apear during the link phase of the install, prior to the glibc workaround I was not getting this. I am a newbie to Linux and trying to give it a serious go but so far I have had little luck
Any help appreciated.

About SQL and Oracle

Hello, I was using a MySQL database and i will soon use Oracle8. I was wandering if Oracle authorize something like mysql_result... I'm looking too for simple documentation about connecting to an Oracle database from a php file using Sql. Do u know books or sites ? Tks

user12317666 wrote:
Does Oracle support T-SQL ? Why would Oracle support a proprietary macro-based language implementation from a competitor?
If it is not supported in Oracle, what is the major grammer difference between T-SQL and Oracle supported SQL ? Oracle has two languages. SQL. PL/SQL.
PL/SQL is formal declarative procedural language with object orientation programming features. It is based on the Ada language (close relative of the Pascal language).
SQL is fully integrated with PL/SQL. Which means that you can write and mix SQL source code with PL/SQL source code and the PL/SQL compiler will figure out which is which and where to make calls to the SQL engine for executing SQL code.
Is there any efficient way for programmer to complete T-SQL transition to Oracle SQL ? Yes. Unfortunately not the answer that you are likely hoping for.
Forget EVERYTHING you did with T-SQL.
There is no real comparison between the two. And not only many differences, but some fundamental and conceptual differences too.

Need help about certification in oracle 9i DBA track

Hello there everyone.
I don't know whether this topic I am posting is allowed or not, but I really need some help. I am doing my BSc computer science second year and I have just started studying SQL now. I always wanted to achieve oracle certified certificate. So I am planning to do Oracle 9i DBA track associate level and then professional level. I will be doing it from oracle certified institute.
But as I have just started SQL language now, so I don't have much experience in SQL. So what do you people suggest? Will it matter anyway to wait for some months or do now as I am gonna join that institute and they are gonna teach me all the topic.? Or should I wait for experience?
If anyone of you have given that exam then please say something about your experience. I will be really very helpful.
Regards,
Prajit.Nair.

Absolutely! I started with 10g because that is the primary release in use at my employer; although we also have some 9i and some 11g in use. So it made sense for me to start with 10g. But if I was just getting started with Oracle, I would start with 11g. An 11g cert is still valuable to employers using 10g or 9i; in fact they may prefer it since they will not have to pay to upgrade your skills when they do upgrade Oracle.

1. It's posssible to download full version. Look at http://www.oracle.com/technology/software/index.html
2. Minimum requirements are described in documentation.
More at: http://www.oracle.com/technology/documentation/index.html
3. AFAIK there are not Standard or Personal edition of Oracle Developer Suite just DB is in that versions.
Check the details about product and choose one.
4. I'think you just need Oracle DB and Oracle DS. Beter check the details about each of product and make your own decision.

Questions about 1Z0-047 Oracle Database SQL Expert

I am planning to take this exam and I have several questions:
1) I am using Steve O'Hearn's 'SQL Certified Expert Exam Guide' book and this states the following about SQL functions:
"Be sure to review the Oracle Database SQL Language Reference Manual and review the lengthy description of all of the SQL functions before taking the exam"
In trial tests it seemed that book's information was enough, but how about real exam? Is it necessary to study something in addition to this book information? You can answer regarding other exam objectives as well, if there is something that I should read from some other materials.
2) The book states that I can add not null constraint to column that has null values, if I specify default value. I tried and cannot, I get error. So the book states it wrongly or do I misunderstand something?
3) The book states that I cannot drop a NOT NULL constraint, but I can get the job done using: ALTER TABLE table_name MODIFY column_name NULL;
I tried and I can execute: alter table table_name drop constraint nameofnotnullconstraint;
4) To use external tables, is only read grant on the directory necessary or also write?
5) I understood from the book that to flashback table (e.g to before drop) I need to have row movement enabled on the table. But I tried and I can make this flashback operation to table that does not have row movement enabled. How can this be explained!
Big thanks in advance!

#1) well, the manual is free; find here the SQL Language Reference - http://www.oracle.com/pls/db112/portal.all_books#index-SQL
#2 & 3) If you proved it yourself, that settles it!
#4) Here's a good article about external tables: http://www.oracle-developer.net/display.php?id=512
I noted this paragraph in it, which might answer your question:
In addition to the standard read-write Oracle directory that we need for our external table, we also need an additional executable directory object for the preprocessor. This directory defines the location of the executables used by the preprocessor (we will be using gzip below). As far as Oracle is concerned, an executable directory is one that has EXECUTE privileges granted on it (this is an 11g feature specifically to support the preprocessor).
#5) don't know

Two basic questions about locks in Oracle.

Hello,
This is about 9i and onwards.
I need to develop a comprehensive analysis of locks and waits and while doing so, following questions popped up.
1) What is the difference between locks and waits?
2) There is a DBA view called DBA_BLOCKERS. The standard Oracle documentation has only one line comment about this view i.e. "DBA_BLOCKER – Shows non-waiting sessions holding locks being waited-on by other sessions.
My question is : Why would a non waiting session hold locks after all? I guess that automatically repeats the question #1 from above, What is the difference between "being waited on" v/s "holding locks with wait" and "holding locks without waits"?
Thanks,
R

1) What is the difference between locks and waits? Lock - something you queue up to get and simply wait until it is available
Waits - Waiting for a Specific event to happen before it can proceed.
Re: Difference between a latch and a lock
2) There is a DBA view called DBA_BLOCKERS. The standard Oracle documentation has only one line comment about this view i.e. "DBA_BLOCKER – Shows non->waiting sessions holding locks being waited-on by other sessions.DBA_BLOCKERS displays a session if it is not waiting for a locked object but is holding a lock on an object for which another session is waiting.

About GET_FILE_NAME in Oracle Forms 9i

Hai,
I am using Forms 9i.GET_FILE_NAME is ot working.SO i download Oracle webutil for 10g.I am using 10g database.
How to configue Webutil?
Please anybody can clarrify this?.

Andy,
the built-in operates where the runtime is, which is the server. Forms 9i is web only and for this reason the built-in no longer works as it did. Use webutil (see otn.oracle.com/products/forms), which has this function (prefixed with "client_") to do exactly what you want it to do.
