Hadoop Implementation in Oracle Database without Exadata/Oracle hardware

All,
Please does anyone know if Oracle plans to implement hadoop without Oracle supplied hardware (Exadata and the like). The reason I'm asking is that at my company, we are now approaching a transation rate of 2000 t/s (transactions per second) and developers are beginning to complain about how slow Oracle is. They've gone ahead to move parts of the database to Cassandra, Redis and DynamoDB (and they're currently experimenting with MungoDB). I understand that some of these DBs operate a key/value system and so it's fast to retrieve data from them. I'm just wondering if Oracle plans to stem this tide by implementing Hadoop without packaging it with a hardware system so as to make it more affordable to implement as there are so many open source DB springing up theses days.
Please any useful information would be highly appreciated. (And if there's anyone out there close enough to Oracle, please, let them know these threats are real and my Oracle database is actually vanishing under me).
Thanks in advance.

However, it struck me that you consider 2000 tps (or so) to be some kind of threshold above which Oracle technology will have trouble keeping up.
developers are beginning to complain about how slow Oracle isNo. It's not Oracle that is slow. Actually they are beginning to complain about how slow that particular system is performing. The application may be slow, and the database may be the bottleneck. But this does not mean that moving away from Oracle is necessarily the right solution.
Granted, there are excellent innovations in database technology right now, especially in the arena of massively parallel database systems. However, I would want to take a long look at the system design, from hardware to database design to application code before concluding that the dbms needs to change. There could be storage i/o sub system issues or application server issues or network problems too.
I am sorry if I am just regurgitating things you probably already know, and likely have analyzed to death with your system. But Oracle can scale well beyond 2000 tps while still serving up good response times. And it is also important to note that moving to these other database technologies sometimes comes with the need to sacrifice some part of the ACID (atomicity, consistency, isolation, durability) properties of transaction management present in a typical RDBMS like Oracle.I have told this story in a few other threads on this forum over the years, but it bears repeating for the OP.
Several years ago (more than I like to think about now) we were evaluating some commercial software for a specialized app in the industry in which I was working at the time. The sales team for one particular vendor kept talking about SQL Sever. I reminded him we were an Oracle shop and asked if their product would run on Oracle. His response was something to the effect that "It will, but we recommend SQL Server because we've found that Oracle bogs down with more than five concurrent connections." The meeting didn't last much longer and I made sure that vendor didn't make the short list. And the lesson is that even commercial software developers (or perhaps especially commecial software developers?) often don't have a clue ...
I'd guess the OP's developers also don't have a clue. Perhaps they are writing their apps to Oracle using what they learned as 'best practice' in SQL Server. Or perhaps they are even more clueless than that and the need to design for scalability and performance never even enters their minds.

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

Gist implementation in Oracle

Is there any Gist implementation in Oracle available using Oracle's extensible indexing method. Since this could greatly help in spatial indexing method defintions.

Other than the scant thousands of pages available through http://docs.oracle.com ?
You could also go to http://otn.oracle.com and
1) Docs and white papers:
- click on Database (under Products, left edge) to get to the Database information
- then click on High Availability
- then click on Real Application CLusters and look at the various whote papers and supplement info
2) Example install articles
- click on Articles (top menu)
- search for DBA / RAC articles by people like Jeff Hunter

Unnecessary complication in PRECISION, SCALE implementation in Oracle

After going through the post
Shouldn't this CREATE TABLE statement error out?
I think that PRECISION and SCALE implementation in Oracle is unnecessary complex.
If you want to store a number like 23.456
create table john (empid number(5,3));
Table created.
INSERT INTO JOHN VALUES (23.456);
1 row created.In NUMBER(5,3) declaration 5 stands for the total number of digits including the numbers after the decimal point and 3 stands for the digits to right of the decimal point.
But don't you think the most straightforward way to store 23.456 would be
create table john (empid number(2,3)); -- 2 for the numbers to the left of the decimal and 3 for the numbers right to the decimal.
Why didn't Oracle Corporation choose a simpler syntax like i've mentioned?

Oracle stores all numbers using significand and exponent (in scientific notation), so using this same framework to declare the number of digits of precision is most accurate and flexible.
Although the use of scientific notation is not common when writing about units of currency, so this usage may seem non-intuitive at first glance.
Your proposed syntax would cause other problems with very large or small numbers.
How about a number like 4.567E100?
This number only requires 4 digits of precision and is perfectly valid in an Oracle database.
The implementation is explained well in the Concepts Guide and is both simple and elegant.

How to implement the Oracle Group by function in Crystal reports?

Hi all,
In SQL, for example we have a group function like:
select district,state, country, continent, sum(no.of people) from world.
Now, How to implement this group function in crystal reports? Please advise.
Thanks in advance..
Regards,
sriram

Hi Vinay,
Thanks for the prompt reply.
In one of our report, we are supposed to perform group by for 14 columns to get sum of 3 columns and there by displaying 17 columns in the report.
When we tried in crystal reports to implement this oracle group by functionality:
1. We created 14 groups from the Insert->Group option.
2. By performing this, we got 14 group sections vertically(one inside the other).
3. Then we created the sum(15th column),sum(16th column), sum(17th column) by Insert->Summary option.
4. We suppresed all the group sections except for the last group.
5. Then, dragged all the groups to the last group section along with the summary fields.
This is how, we tried to acheive the oracle group by function in Crystal reports.
Please advise, whether our approach is right. If not, please suggest the appropriate approach with a bit detailed explanation.
Thanks,
Sriram.

Parameterized queries not implemented in Oracle OLEDB ?

Hi Xperts !
I'm implementing an ADO application with Oracle Provider for OLEDB and get an error when accessing Parameters:Count properties of an ADO command object.
Is this not implemented in Oracle OLEDB ?
Is there a workaround to get and set parameters for a query ?
Thanks in advance.
Phil

It can in principle be achieved in SQL (depending on what result set you require) with CONNECT BY and SYS_CONNECT_BY_PATH in 9i and later and with POWERMULTISET in 10g. No doubt this could be done in 8i if absolutely necessary.
Possibly DBMS_FREQUENT_ITEMSETS in 10g supports this kind of analysis.

How are JDBC batch updates implemented by Oracle?

When you're looking to reduce commits you typically think of JDBC batch updates.
I'm just wondering how are these implemented by Oracle and is there ever gains to be had to reducing commits in an Oracle specific way like say using VARRAYs with procedures?

Using database without ODBC

It's possible to use a database without ODBC in Labview??

IDILIO wrote:
Hi Rolf,
At this moment I m using the Microsoft ODBC driver for Oracle and it works ok, but my problem is when i do several reads at the database it reflects in a big delay for the Front Panel.
As i know that the ODBC driver is a very slow method to access database i m searching for a faster way to do it. Do you have any suggestions?
It's not ODBC that is necessarily slow. It is usually the way you retrieve data that has a lot more influence on the speed of the data retrieval. In the case of the Microsoft ODBC driver it might be that this driver is not specifically optimized for speed for various reasons.
First implementing someone elses protocol is always difficult (not sure how well Oracle documents their protocol) and the temptation to stop when it is working rather than when it is working perfect is much bigger. Also it is of course not in Microsofts interest to provide you with a solution for Oracle that outperforms their own SQL Server interface so that is even one more incentive to stop when it is working rather than when it is working perfect.
Have you tried to use the Oracle ODBC drivers? They might be more optimized so that retrieving data through ADO can be faster.
Very important is how you retrieve the data however. The classical and simple way of retrieving data element for element is very slow. For this ADO/OLE DB has introduced rowsets which query several rows of a query result at once in one single driver request and then later allow the client to retrieve the elements locally into the native data. This is for remote databases always a huge performance improvement, since the bottle neck here is the network communication and not the memory manager or IO interface.So requesting one whole bunch of rows at once instead of element by element reduces the network traffic substantially and increases the performance at the cost of some extra memory usage for local caching. And the best thing is that the ADO rowsets can be mapped to ODBC cursor sets if the ODBC driver supports cursor sets and the ADO ODBC bridge does that transparently for you. Accessing ODBC directly you could also use cursor sets, but the API for doing that is really not for the faint hearted. ADO rowsets in comparison are very simple to use.
Try to read a bit about ADO database query optimizations on the web to get an idea of the techniques used and they usually can be quite simply translated to ADO methods as used in the Database Connectivity Toolkit or any of the other ADO based toolkits out there.

Recover database without controlfile and redo logs

Hi guys,
I am doing a testing with an Oracle Database 11.1.0.7.0, I want recover a database in this scenario without using RMAN:
-All controlfiles are missing
-All redo logs are missing
-I have a Backup Controlfile To Trace Resetlogs (bkp_controlfile.sql)
-The database is in archivelog mode
-The database was created with OMF (Oracle Managed Files)
So I have done this steps:
1) When the database was opened I rename all controlfiles and all redo logs
2) Shutdown Abort
3) I run the bkp_controlfile.sql, here I have a problem...
The database put in NOMOUNT, the controlfile was created and started the RECOVER DATABASE USING BACKUP CONTROLFILE, but when run ALTER DATABASE OPEN RESETLOGS; appear this:
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1:
'/u02/app/oracle/oradata/OMF/datafile/o1_mf_system_68hzcb2z_.dbf'I wasn´t expect this because I don´t want recover a datafile, I only want open with resetlogs.
Any suggestion to help me?
Thanks a lot.

Excelent! Thanks for your answers Markus and Hemant.
In conclusion...
- If we have all redo logs availables we can recreate the control file and recover the database without any problems using backup controlfile to trace noresetlogs*.
- if we haven´t all redo logs availables, there are 2 situations:
1) If the database shutdown properly:_ We will be able to open the database using recover database using backup controlfile until cancel*.
2) If the database doesn´t shutdown properly:_ We won´t be able to open the database with only a backup controlfile to trace.
With all this I close this thread. Was very good experience.
If anyone would add something will be welcome.
Thanks for all
I wish add the results of one of my tests: if I did all the steps in only one session of sqlplus I can shutdown properly the database, but if do the shutdown immediate* in a new session I can´t shutdown properly the database. Here I post the output:

How to recover database without archive files

Thanks in advance for your help.
Regards,
Carles

There are serveral information missing in this posting and as a support personnel, I would like to find out more when I see postings like this.
1. This person wants to "Test" his backup and recovery in NOARCHIVELOG mode.
2. He/She did not say his database had already crashed or had a problem.
3. He/She did not give any indication the kind of scenario he wants to recover from.
4. He/She did not mention the state of his database at the time of he posting.
5. He/She did not mention the Release of his Oracle Server or Platform.
6. He/She did not mention the type of backup he already has in place (although provided later as Full COLD Backup). How "genuine" is the back?
7. What actions has already been taken to attempt recovery.
In my support experience, I normally would go through a list of questions witht he use/client to get the full picture of the current status of the database before I give answers that would worsen situations, especially in a Disaster Recovery sitaution.
Personaly, I would suggest you have a look at the list above. One of the most important is number 3 (The Recovery Scenario), then number 4, number 6 and 7. Number 7 will determine the situation of your database. So, when you ask for SQL commands to use, there are different commands for different kind of recovery depending on what has gone wrong or what kind of file is damaged (Datafiles, Logfiles, Control Files, one tablespace, one table, entire database gone, etc).
