[b]Open Source Databases ![/b]

Hi every one Is there any body nice who can help me ?
Q---What we can understand by the term Open Source
Databases and products? Can anybody explain with examples
links and information source and Sites ?
Q---Open source Databases are worth investigating and prototyping? What does it mean?
Q--- Open Source Databases are indeed delivering
Medium sized enterprise-scale performance
Scalability
Robustness
Manageability? What does it mean by?
Q--Users & Independant Software vendors with respect to Open source Database?
Q--What we can understand by Open Source DBMS?
Q-- Some companies those have transitioned to Linux from Unix platforms buy minimal support from the Linux distributors and rely instead on support from the Open Source Community?Is this approach comes at cost?
Q-- MySQL is full relational database with SQL support.Users view MySQL as simple, small footprint, and performant?Can any body xplain it more precisely?
Q-- What do you mean by Deadlock detection, ACID(atomicity, consistency, isolation and durability), Row level locking, Open Database Connectivity?
Q--In MySQL Bit-mapped indexing (for large data warehouses)?
Q--Open database Connectivity (ODBC) and Open database source?
Q--How Open Source Database is related to Oracle ? I mean object relational Database?
Thanks in advance
One can reply me on private E-mail adress i.e;

I have been looking into MySql and its not really impressed me. Not sure that there is anything better.
And it depends on your usage.
InstantDB is one http://www.lutris.com/downloads/index.html but it is limited to non-commercial use.
Interbase (firebird) at http://firebird.sourceforge.net/
I believe the unix side usually supports a variety that you could probably search for.
And if cheap is ok, rather than free and open, and using it only for developement then you can get full versions of Oracle and MS SQL Server very cheaply.

ADF (View Object) with open source database

Hi all,
Recently, I am evaluating JDeveloper 9.0.5.2 ADF with an open source database (Firebird).
I follow the instruction to:
1. Create an entity object
2. Create a view object for the entity object in 1
3. Create an application module for the view object in 2
4. Right click on the application module and test -> all worked fine
5. I created a jsp and drag the view (in 2) to it from Data Control Palette
6. Test it in OC4J -> an error occurred (not because of jdbc config)
JBO-27122: SQL error during statement preparation. Statement: SELECT * FROM (SELECT Department.DEPT_NO, Department.DEPARTMENT AS DEPARTMENT1, Department.HEAD_DEPT, Department.MNGR_NO, Department.BUDGET, Department.LOCATION, Department.PHONE_NO FROM DEPARTMENT Department) QRSLT ORDER BY DEPT_NO
GDS Exception. 335544569. Dynamic SQL Error SQL error code = -104 Token unknown - line 1, char 16 SELECT
To my knowledge, the error should be due to Firebird doesn't support the query syntax " select * (select col1, col2... from table) QRSLT where... order by... "
I am quite headache as this query is automatically generated by JDeveloper. I am figuring out whether I can change it. It seems that I have to play with the ViewObjectImpl class.
I do think ADF is an amazing technology. However, is it only so amazing with the Oracle technologies? Please correct me if I am wrong.

Dear Shay Shmeltzer,
Thank you for your reply. After hours of trying on Firebird, I still get the error:
JBO-27122: SQL error during statement preparation. Statement: SELECT * FROM (SELECT Department.DEPT_NO, Department.DEPARTMENT AS DEPARTMENT1, Department.HEAD_DEPT, Department.MNGR_NO, Department.BUDGET, Department.LOCATION, Department.PHONE_NO FROM DEPARTMENT Department) QRSLT ORDER BY DEPT_NO
GDS Exception. 335544569. Dynamic SQL Error SQL error code = -104 Token unknown - line 1, char 16 SELECT
I then downloaded the MySQL 4.0 and install on my system to do the exact procedures. No error! Thing works fine! Oh man...
For the Firebird case, a strange thing to note is that the data table (I dragged) contains data, but the error message is on top of it.
Actually, I don't have a particular database preference but I do hope ADF can work equally for these open-source databases. I think the problem may also be contributed by Firebird. Hope that I can figure it out this week.
Regards,
Hons

Is mysql a free open source database or do you need a license for it in prd

is mysql a free open source database or do you need a license for it in production.

Hi,
It should be free under GPL (General Public license).Usually it will comes with your operating system distribution (eg:RHEL)
If you download it from Oracle site, it should have the commercial license tied to it, and you need to pay for that if it is in use for production.

What's the Best Open Source DB for use with Kodo?

Hi everyone,
In terms of ease of setup and use, tools to view info in the database, and least difficulty in
running with Kodo, what is the best open source database to use? I'm use to using Oracle and
SQLPlus. I need to use an open source DB for a learning environment, and I'd like your informed
opinion.
Thanks,
David Ezzio

I have been using postgresql 7.1 with Kodo for a while with mostly positive results, and currently
have it deployed with Kodo 2.2.3. I prefer it to mysql because its feature set is a little richer,
and supports transactions natively. My experience with mysql (without jdo - I haven't tried it with)
is good, but there were little things missing in mysql 3.x, e.g. the ability do do a join in a
DELETE statement.
BTW, there are some severe problems somewhere in the 2.2.4 release with postgresql if you intend to
eventually deploy on it. It also apparently has some problems invoking postgresql's indices, making
it a little less than optimal. But as a learning environment, it's what I'd recommend.

Here is the rundown of the databases I have experience with:
MySQL: Fairly simple to install (especially if you run Debian Linux), but
configuration, especially adding users, can be a pain. A separate open
source project called "mysql-navigator" makes it fairly easy to do
simple queries, inserts, etc. In most of my tests it outperforms
PostgreSQL, but your mileage will vary. It has a sane CLI that supports
modern features like line history, etc (unlike the horrific SQLPlus).
PostgreSQL: People often say that it is a more "academically
correct" database than MySQL. I've also found it to be quite a bit
easier to set up. Their GUI (called "pgaccess") is simplistic, but does
most things you need. Has a CLI similiar to MySQL's.
HypersonicSQL: By far the easiest to set up (just drop the jar in your
CLASSPATH), but is java only, can be rather slow, and has no GUI tools
available that I know of (except various free vanilla-JDBC GUI tools).
We feel that Kodo works quite well with all these DBs. The MySQL JDBC
driver seems a bit less buggy than Postgres', but their transaction
support is very recent and not very well tested. If I had to pick one or
the other, I would probably go with MySQL.

Open source monitoring tool for oracle Database

Hi,
Please suggest me any opensource tool to monitor the health, availability and performance of the Oracle Database that can be accesed through web client
Thanks in advance

Robert,
Thanks for the update, ya i basically need the tool to monitor the DB, but at the same time, if CPU is going high due to any query or any other reason, we must get the alert, the tool currently we are using triggers a mail for both, DB as well as CPU when it goes high, similar one is needed
ThanksGrid control or database control will do this for you, there is a rather big however, er however. Being notified is a part of the diagnostics pack functionality (ludicrously and unjustifiably IMO). That means a license cost (unless you are already licensed for it). nagios does this as others have said as do shell scripts. I'm not aware of an open source tool that does all you want without scripting though.

Don't give up just because there are other options out there.
Adobe is only giving up the free tool for education purposes, or unemployed developer. You didn't say if you were one of those.
I believe over time there will be plenty of room for alternate IDE approaches that support the Flex Framework; and in fact there are quite a few options already out there.

DBAShell - New Open Source Project for Oracle DBA's

I'd like to have this project included in the Open Source Oracle tools list at: http://www.oracle.com/technology/community/opensource_projects.html
I've been an Oracle DBA for quite some time (since 7.0.13) and a developer for many years. One of the things I've always wished for was an easier way to set up environment variables for different Oracle Homes and a way to provide passwords to scripts without embedding them in plain-view.
About 3 years ago, I started a set of functions and scripts at my company that did exactly just that and provided many more functions for things like checking database status, running scripts quietly unless errors are detected, running actions in parallel (like fast shutdowns at once, or multiple analyzes), restarting databases in a guaranteed fashion, aliases to common folder locations, etc..
About a month ago, after putting all this time and effort into these scripts and using them in production all this time, I realized I wanted more out of the scripts like support for other databases and thought that it would be best if I gave it new life as an Open Source project.
So that is how http://sourceforge.net/projects/dbashell/ was started. Now its in a second release (DBAShell 0.85) that is more modular and would allow other people to easily add support for other OSs, other Shells, and other Databases.
Here is a description of the project from the latest news item:
DBAShell is a project based around Shell functions and scripts designed to make it easy for DBA's to use Databases in a command line environment. Currently supported is Oracle with ksh and bash on AIX, Solaris, Linux. The code base itself is 3 years old and has been in use in Production environments all of that time.
Features include:
* Automatic setting of all environment variables based on SID requested.
* Manage PATH's and other path like variables for each ORACLE_HOME needed.
* Run scripts with stored passwords (no more hard-coding of passwords!!)
* Automatically set SID based on Script location (makes it easier to share scripts between SID's)
* manage temporary script output and check for oracle errors in output
* check database status and versions from scripts
* stop/start databases in parallel (faster startup)
* compile all database objects
* analyze objects in parallel (Faster analyzes)
* set aliases and variables for common SID areas, etc..
* many helpful commands for common Oracle tasks
Over a thousand people have already downloaded the prior release and more are downloading every hour.
I'm seeking feedback from anybody that would be willing to take a look at the project, trying it out, give me any feedback you have on it, and perhaps even direct me to where I could best promote this project.
I wrote a tutorial that shows at a glance some of the more useful features of DBAShell:

Open Source project

Open Source Project Announcement...
I have started an open source project to build a module for
PHP4 that will allow direct calls to Tuxedo services from
the PHP script, the project name is php-tuxedo.
Think about it for a second... The ability from inside a
PHP web page to directly call already existing Tuxedo
services anywhere in your environment. Just like PHP can
open a database connection to Oracle or Sybase, it would
open a Tuxedo connection as a Tux client to a Tuxedo
middleware environment.
For those who have used PHP, you know how easy it is to
build dynamic web pages. But those pages are mostly limited
to database queries or flat file access for data. With this
project you could call all your existing enterprise Tuxedo
services directly. I believe this would be a very powerful
enhancement to PHP's capabilities.
To those familiar with Tuxedo, you know about how powerful
an implementation of Tux middleware services can be for
departmental and enterprise solutions.
I want to bring these two pieces together.
Project status. The project is in its early infancy, but
some parts are functional. I have successfully built a
client page that uses a STRING buffer to call a service with
tpcall and returns a STRING buffer back. Primitive? Sure,
but this is only the start. I have ideas of how to
implement many other functions and buffer types including
FMLs.
There is much work to do, but if you are interested please
check out http://php-tuxedo.sourceforge.net. There you can
download my first cut and more importantly follow the
project as it progresses. For the really ambitious I would
welcome any testing or development help on the project.
Please note I’m posting this note to several lists I don’t
normally monitor, so I may not see a reply on the list.
Hope to hear from you.

Open source shopping cart wont open with safari

Hi all...
I'm designing cart templates for a company that supplies an interface for uploading product to an open source shopping cart. The problem is I can't open the shopping carts with safari. They are fine with firefox and on a PC. (forgive me for swearing) The sites are open source carts based on php scripting with a lot of compressed data. A software interface is used to upload products etc... The error I get is
"Safari can’t open the page “not sure if I can put the link here as it is a business”. The error was: “bad server response” (NSURLErrorDomain:-1011) Please choose Report Bug to Apple..."
It's the same for all the sites using the carts.
Is there a fix at the user end or does safari simply not have support for these carts. Any help would be awesome....

PCI Compliance. As a merchant (online or brick & mortar store), you must take necessary steps to ensure your customer's CC info doesn't fall into the wrong hands. One way to do this is to pass your online customers off to a 3rd party processor like PayPal or Authorize.net. These companies are experts in safely gathering sensitive data, encrypting it and transmitting it to your payment Gateway and Merchant Bank account. This way, your customers never enter any sensitive data into your site's databases which avoids a lot of headaches for the web developer and merchant.
Server Security. Use a reliable web host. I can't emphasize this enough. Cheap hosting is no bargain especially if your host doesn't take reasonable steps to secure their servers at their end.
Lock down your php scripts & form log-ins to defend your site against possible hackers & robot exploitation. If your site is ever compromised, you will need reliable backups of your Site files and MySql data. Make sure to backup these files regularly and store them in a safe place.
Backend log-in. Use strong, encrypted passwords -- 17 characters, upper & lower case with symbols. If you can remember your passwords, they're not strong enough. I keep mine written down in a Rolodex.
Change the Admin log-in name to something less obvious like GrandHighExhaltedMysticRuler or something only you will recognize as the site's admin level user. It's also a good idea to change your server, database and backend log-ins regularly.
Finally, consider running SecureLive on your web server. I have it running on a dedicated server and this software has more than paid for itself. It identifies hacker attempts, blocks the user and sends the hacker's IP address to an FBI database. SecureLive - Home

A verb conjugator in C (was: Ideas for an open source project in C)

Hi,
I have to write a relatively complex program in C for my university programming course. We can either use a given topic (a hotel management software - quite some work, but not very challenging) or something of our own choice provided it is not too simple.
Being a good open source citizen, I want to do something from which other people might profit.
My first thought was a xmms2 client after an idea I had for a long time, but that's no fun without objects, particularly because xmms2 uses boost as well. I'm not sadistic enough to do this. (I like object orientated programming...:()
We can use external libraries (e.g. ncurses, GTK2), but should use ansi C (that's C89) and it should run on Windows as well, but I might talk my way out of these two things if necessary.
I'll do a lot of brainstorming myself, but I would appreciate it a lot if you could give me ideas. It would be a pity to waste this opportunity with a useless hotel management software if I could create something usefull instead.
Thanks a lot for any ideas.
kind regards

I'm still not very familiar with the Italian conjugation, but judging from Spanish it's a pretty simple thing to do, at least when you only think about outputting all the conjugated forms for an infinitive. I'll make an example with Spanish, but it's almost the same for Italian:
procedure:
Step 1: Check for suffix -ar/-er/-ir and the root of the verb and apply the default rules as defined in the data file. (i.e. suffixes -o,-as,-a,-amos,-áis,-an for -ar and present and so on)
Step 2: Check the data file for an entry for this verb and replace any irregular forms. (This means replacing all forms for a irregular verb or maybe only the participle - imho the most efficient way while still KISS)
Example: comer
Step 1: suffix -er, root com; use rules in data file for -er
Step 2: verb is not in database, regular
Example: escribir
Step 1: suffix -ir, root escrib; use rules for -ir
Step 2: verb is in database, only exception to regular conjugation is the particible "escrito"
Example: ir
Step 1: suffix -ir, no root; apply rules for -er (Doesn't make sense, but it is irregular anyway)
Step 2: verb is in database, about everything is replaced
Recognizing the forms, i.e. doing a reverse search is a bit harder this way, but actually really interesting.
ibendiben: I like the idea, but I wouldn't realize this in C, but a follow-up project written in PHP is very well possible. I'll have the data files and algorithms already, so it's not too much work.
But I wanted to do some work on the aMule skin code as well or we might actually release 2.2.0 before I'm finished...
Edit: I think I'll use a webfrontend (I'll worry about windows later...): http://www.ibm.com/developerworks/syste … -nweb.html

c:\>set oracle_sid=test1
c:\>sqlplus /nolog

ORA-12560 TNS:Protocol adapter Error.
But if i use the folowing procedure i can able to open the cloned database
c:\>set oracle_sid=test(NOte test is the source database not clonned database)
c:\>Sqlplus /nolog
SQL>conn sys/oracle as sysdba
SQl>startup nomount pfile='c:\oracle\pfile\inittest1.ora'(this is the location of init.ora file for cloned database)
SQL>alter database mount;
SQL>alter database open;
Now cloned database is up and running.
Now if i try to open the original database (TEST) then i am getting the error
c:\>set oracle_sid=play
c:\>sqlplus "/nolog
SQL>conn sys/oracle as sysdba
SQL>startup
ERROR:database is already up and running
SQL>select name from v$database;

Can any one help me to open two databases at same time.
Thankx...

The 'Third Party Connections' drop down box on the 'Source Database' step in the Migration Wizard is empty.

Here are the environmental details:
SQLDeveloper 32-bit Version 3.2.20.09 (Build MAIN-09.87)
Oracle Database: 12C single instance (no RAC)
Oracle client: 12C 32 bit
Windows 64 bit desktop
I am attempting to migrate an MS Access application to Oracle. I pick the ‘Migrate’ selection from the ‘Tools’ Menu SQL Developer. This puts me into the Migration Wizard. When I get to the ‘Source Database’ step of the migration wizard, the ‘Choose the Third Party database from which you are migrating’ drop-down box is not being populated with the current available connections. It is empty. If I type a valid connection name into the box, SQL Developer takes it on this screen but does not keep it for the next screen/step. It has no persistence. I even tried to make sure that each connection was open/connected before beginning the migration process.
Due to the fact that I am attempting to migrate an MSAccess application, I am mixing 32-bit and 64 bit software. This may be the issue as to why the drop down is losing addressability. I have not applied any patches to this version of SQL Developer.

Hi,
If you need easy way to migrate Microsoft Access to Oracle probably it is more reasonable to review some tools specially designed to this purpose. For example:
Access to Oracle converter by Intelligent Converters
Access to Oracle converter by SpectralCore
Access to Oracle converter by Interface Computers
Hope, this will help.
Sincerely,
Vlad
