Difference between oracle and BEA JDBC Drivers

One of our application plan to move from BEA JDBC drives to Oracle drivers.
We use Weblogic 9.2 as application server and Oracle 10g as the database.
Questions
=======
1. What is the basic difference between these drivers and how do we decide which one to use.
2. What can be the impact of moving to Oracle drives from BEA on the overall application...?
3. Other than change in the jdbc.datasource.url = jdbc:oracle:thin:@, do we need to take anything else into consideration.
Pls. let me know in case any further details are required.
Thanks in advance.

"1. What is the basic difference between these drivers and how do we decide which one to use."
They are totally different products made independently by different companies.
"2. What can be the impact of moving to Oracle drives from BEA on the overall application...?"
As long as your application uses standard JDBC APIs, the impacts will be minimized, and
unpredictable, some running faster, some slower... Any bug list for one driver will be
different than for the other. If you use any driver-specific extension APIs, they won't
be in the other driver.
"3. Other than change in the jdbc.datasource.url = jdbc:oracle:thin:@, do we need to take anything else into consideration."
Also changing the diver/datasource class name, and reviewing any arguments/driver properties.
Property names and functions are usually driver-specific.

Find the difference between loading and registering the drivers..

Dear Sir..
Could you please help me to find the difference between two activities..

to do it all.You load a class - it isn't specific to a driver.
That is part of java - not JDBC.
Normally JDBC drivers register themselves when the class is loaded. This is specific to the driver and has nothing to do with a user of the driver. It is only a concern to someone who must implement a driver.

What's so hard about finding a "best linux distro for installing Oracle11g"? The supported distros are listed in the fine Installation Guide for Linux. At the top of the list is Oracle's own Oracle Linux, which is in the same family as Red Hat.

What are the Basic Differences between Oracle and MS-SQL server Database?

Hello,
anybody pls Guide me about the Differences between Oracle and MS-SQL server Database.and also IBM Databases also
Regards,
Balaram

SQL Server only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
In comparison with SQL Server , OracleDatabase supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
The SQL Server advantages:
SQL Server holds the top TPC-C performance and price/performance results.
SQL Server is generally accepted as easier to install, use and manage.
The Oracle Database advantages:
Oracle Database supports all known platforms, not only the Windows-based platforms.
PL/SQL is more powerful language than T-SQL.
More fine-tuning to the configuration can be done via start-up parameters.

What are the differences between Oracle and other NoSQL database

Hi all,
I would like to know what the differences between Oracle and other NoSQL database are.
When and why should we use Oracle?
Is Oracle NoSQL database link with Big Data Appliance?
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?
Do we also have eventual consistency with Oracle NoSQL database? Can we lose data if master node fails?
Are transactions ACID with Oracle NoSQL database? How can we prove it?
Thanks.

Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
Do we also have eventual consistency with Oracle NoSQL database? Yes.
Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.

Differences between Oracle and Oracle Rdb.

My background is mainly VMS, and so I have grown up (since 1984) with DEC Rdb (now Oracle Rdb). I am starting to get into Oracle, and therefore, starting to learn the subtle differences. With this in mind could someone educate me as to the default transaction type when using SQLPLUS (using interactive SQL it's READ WRITE). What is the initialization file called for SQLPLUS, and are there equivalents to the logical names SQLINI, SQL$DATABASE, SQL$EDIT, etc.
If there is someone out there with experience of both, may be you could ease my pain by posting your pearls of wisdom, or tips, here to help me along the way.

OK, I'll try a few, having moved from VAX/Rdb to Oracle 10 years ago.
Oracle's default transaction state is read-write, isolation level READ COMITTED. This means you generally don't need to do a "SET TRANSACTION" at the start of a transaction, and certainly don't need to keep doing commit;set transaction to see the latest values.
In read-write transactions Oracle does not lock rows on read to maintain consistency in the way Rdb used to. Usually people use SELECT ... FOR UPDATE, or update directly (without a separate select) rather than using isolation SERIALIZABLE, which is the equivalent of Rdb's default.
A script login.sql is executed at the start of a SQLPLUS session. On Unix, it looks for this in the current directory, and the home directory.
On UNIX, SQL$DATABASE becomes "export TWO_TASK=dbname"
On Windows, SQL$DATABASE becomes "set LOCAL=dbname"
I strongly recommend Tom Kyte's Expert one-on-one Oracle book to help your transition, and his web site asktom.oracle.com
Good luck, and welcome.

Sorting differences between Oracle and SQL Server

Hello All,
This question is related to both Oracle and SQL Server
I have a requirement where I want to compare 2 tables line by line. One table is in Oracle and other table is in SQL Server
And suppose that both of the tables don't have a primary key. Now when I sort the records using order by clause for a column then -
Rows having null values in that column of Oracle are placed at the bottom.
Where as Rows having null values in the same column of SQL Server are placed right at the top.
How can I make either of them to behave like other.
My sole aim is to have same order of occurrence of rows in both Oracle and SQL Server tables so that I can compare them line by line.

For example :
select * from emp order by comm;
So all null value in comm column are at the end.
Now if you wish to get them on the top of select output then :
SELECT EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,NVL(COMM,0) COMM,DEPTNO FROM EMP ORDER BY COMM;
Means i am using NVL (oracle function) function. If comm column is having null value it will converted to zero value at the time of exectuion of select query.
So, now comm column is having zero value in select output and SQL Server is having nulls at the top. I do'nt know who to make nulls to zero in SQL Server. So issue solved.

Key Configuration differences between SAP and ORACLE Financials

Hello,
After spending good 7 years in SAP related projects recently I started working in ORACLE Applications. I used to be an ORACLE programmer years back. To my surprise the same ORACLE Forms are still very much the heart of the ORACLE UI.
Then I thought what will be the key differences between ORACLE and SAP in terms of configuration elements. While I know a bunch of configuraion items in SAP , I am not sure about the same in ORACLE world. I am not even sure some of the configuration items that are available in SAP exists in ORACLE.
Does anyone know both sides of the coin ? The terminology and design ?
SAP has
Client,Company code, Business area, Functional Area, GL, Posting Key, Document Type.
I am trying to get the details of the equivalents of these in ORACLE.
Does anyone know it ?
For e.g , when you post to AP or AR in SAP , GL is updated automatically. In ORACLE you post to a AP Book or AR Book then Run a batch to move them to GL Book.
ORACLE uses SQLLoader to load data . You can write a PL SQL and update the tables directly, which is not the case in SAP. For dataloads and conversions, SAP uses BDC's ( though XI can be used but its slow).For ORACLE its the good old SQL and PlSQL combo.
What are the equivalents of the configuration elements in ORACLE world ?
Also what are the major differences between these two in terms of designing a financial system.
Does any one know ?

Genie,
I agree that a case is made on how well these two ERPs solve the day to day tasks before a company chooses one of these two. But my question is aimed at finance to begin with. You are going to need a general ledger for any company or government regardless of ERP. And how well you can drive the ledger to map your business is the key here.
The way ledger is built is around a business area ,company or country and is very tighly designed in SAP. I would like to know if there is any equivalent of the configuration items in ORACLE. I am more interested in terminology of ORACLE.
For example ,
SAP ====> ORACLE
GL ==> Book In ORACLE
Document Number ===> Invoice Number
Posting Period in SAP ==> Posting period In ORACLE
Most of the terms are finance terms , so they are common ( eg. an account number is an account number in ORACLE and SAP ) between two systems. I am interested in any specific thing that is available in ORACLE but not in SAP and vice verse.
thanks for the link you have provided.
Its very useful.

Difference Between Thin and OCI drivers

Hi,
Can anyone tell me what the difference is between the OCI and thin JDBC drivers. Or point me to some documentation.
Why would you use the thin driver over using the OCI driver??
Thanks for any help.
Steve

- The thin driver is easier to deploy, since you don't need any Oracle software installed on the client.
- The OCI driver will have slightly more functionality than the thin driver because it's able to leverage the Oracle client.
- If you're doing a lot of data retrieval (lots of bits over the wire), the OCI driver will tend to be faster.
- If you're not retrieving a lot of data, the thin driver may be faster, since the OCI driver incurs a context switch when it goes to make OCI calls via JNI.

Differences between oracle 10gr2 and 11gr2 warehouse bulider

Hi All,
Could you please let me know the main differences between Oracle 10gr2 and Oracle 11gR2 warehouse builder.
Also , it would be great if anyone point me to the document where i can see the major differences.
Thanks,
Naveen.

Hi Naveen,
The major difference between OWB10gR2 and 11gR2 is the target RDBMS.
In 10gR2 you have to use ORACLE as your target RDBMS (unless you are going for DB Gateways, that is a complete different story).
Where as in 11gR2 allows you to use any RDBMS as your target system . This is achieved by Code-Template mapping.
All is needed is that proper jdbc driver for the target system.
Also 11gR2 supports OBIEE RPD creation and etc.

Can Oracle be forced to use the spatial index for sdo_filter in combination with an or clause? Difference between Enterprise and SE?

We’re seeing the following issue: sql - Can Oracle be forced to use the spatial index for sdo_filter in combination with an or clause? - Stack Overflow (posted by a colleague of mine) and are curious to know if this behaviour is due to a difference between standard and enterprise, or could we doing something else wrong in our DB config.?
We have also reproduced the issue on the following stacks:
Oracle SE One 11.2.0.3 (with Spatial enabled)
Redhat Linux 2.6.32-358.6.2.el6.x86_64 #1 SMP Thu May 16 20:59:36 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
11.2.0.3.0 Standard Edition and 11.2.0.4.0 Standard Edition (both with Spatial enabled)
Microsoft Windows Server 2003R2 Standard x64 Edition
However, the SQL works fine if we try it on Oracle 11.2.0.3.0 *Enterprise* Edition.
Any help or advice would be much appreciated.
Kindest Regards,
Kevin

In my experience sdo_filter ALWAYS uses the spatial index, so that's not the problem. Since you did not provide the explain plans, we can't say for sure but I think yhu is right: Standard Edition can't use the bitmap operations, and thus it'll take longer to combine the results of the two queries (because the optimizer will surely split this OR up in two parts, then combine them).
BTW: when asking questions about queries here, it would be nice if you posted the queries here as well, so that we do not have to check another website in order to see what you are doing. Plus it will probably get you more answers, because not everyone can be bothered to click on that link. It would also have been nice if you had posted your own answer on the other post here as well, because my recommendation would have been to use union all - but since you already found that out for yourself my recommendation would have been a little late.

Difference between upgrdae and migration about oracle database

Difference between upgrdae and migration about oracle database
please give the comments

Well, the question is almost philosophic... 
In 9i, there is a Migration Guide whereas in 10g there is a Upgrade Guide. 
Furthermore, in 9i, there is the command line startup migrate whereas in 10g that's startup upgrade.
Somebody think upgrade when go to new release, and migration when go to new version. 
Others think upgrade when new version replace database in place, and migration when new version include a move of database. 
Another point of view is : upgrade is for technical, and migration for application/data. 
 
Well, after these explanations, your upgrade/migratation notion will not be more clear, but I think that is not very important, only a terminology game. The most important is to know what you need : new version or new release.
