Hardware Configuration: SATA2 and SAS on oracle 10g

Hi
We are currently operating an in-house server with 2xSata2 drives running OS and applications and 5xSCSI disks for data index and log partitions. We're trying to transfer the database to a hosting service and are considering using a 2xSAS disk configuration. Does anyone know how is this likely to affect the performance of the database?
thanks in advance
Brendan

Its all about spindles. Oracle likes to be on as many spindles as possible. If you have performance problems and/or you don't want performance problems, don't go cheap on the drives. Raid 5 sucks too. You want Raid 10. Just go to www.baarf.com for more infomation on not using Raid 5. Its like putting lawn mower sized wheels on your Corvette, you are not going to go very fast.

How to integrate from MS SQL SERVER 2005 and Flatfile to Oracle 10g.

Hi
I am new to ODI. I am trying to load sample data from MS SQL Server 2005 and Flatfile to Oracle 10g.
1. I have created three models.
1-1. SQL2005 (SRC_CUSTOMER table)
1-2. Flatfile (SRC_AGE_GROUP.txt & SRC_SALES_PERSON.txt)
1-3. Oracle 10g (TRG_CUSTOMER table)
You may know I got those environments from the ODI DEMO environment.
2. I could able to reverse the tables also.
3. I have created an interface which contains source table (from MSSQL 2005), Flatfile and target table from ORACLE model.
4. I have imported the knowledge modules. But I am confusing in selecting the knowledge modules to source and target tables.
I've selected LKM File to SQL for flatfile model.
I've also selected LKM SQL to SQL for MSSQL 2005 model and IKM Oracle Incremental Update for the target table (ORACLE).
I've also implemented the interface that I created. It worked without errors. But there is no data in target table which is TRG_CUSTOMER.
I really would like to know what happened and what the problems are.
You can email me [email protected]
Thanks in advance
Jason Lee

what did give for SRC_AGE_GROUP SRC_CUSTOMER join condition
if it is
(SRC_CUSTOMER.AGE=SRC_AGE_GROUP.AGE_MIN) AND SRC_CUSTOMER.AGE=SRC_AGE_GROUP.AGE_MAX
give it as
(SRC_CUSTOMER.AGE>SRC_AGE_GROUP.AGE_MIN) AND SRC_CUSTOMER.AGE<SRC_AGE_GROUP.AGE_MAX

Oracle software is install successfully. Then automatically run Database Configuration Assistant, that must be install example instance.
But it show error window: "ORA-00959: ?????? 'EXAMPLE' ?? ??????????".

Frist of all the actual error message in English would be,
ORA-00959: tablespace <strings> does not exist
Cause: A statement specified the name of a tablespace that does not exist.
Action: Enter the name of an existing tablespace. For a list of tablespace names, query the data dictionary.
In your case that will be tablespace EXAMPLE.
How did you get this error, is this some tablespace you are trying to create?

Could you please instruct me on how to achieve?
I look forward to hearing from you all.
Thank you.

Hi, use RMAN utility
do this
rman target sys/*** nocatalog
run {
allocate channel t type disk;
backup
    format '/app/oracle/backup/%d_t%t_s%s_p%p'
      (database);
   release channel t;

How to archive and Purge in Oracle 10g based on data

Hi,
Our requirement is that based on some rules stored in static tables we want to perform Archiving, purging and compression of data in Oracle 10g.
Can anyone guide me to proper information material for how to go about this?
Thanks!
Avinash.

Hi,
Thanks for the information.
But this traditional way of doing is archiving is for maintenance and backup operations.
We want to have this process online, without taking db offline. In this case will this approach work?
In our case, the rules can be like -
1. For table 'A', if rows exceed 10Million, then start archiving of the data for that table.
2. For table 'B', if data is older than 6 motnhs start archiving of the data for that table.
3. Archiving should be on for 15 minutes only after that should pause, and should resume whenever user wants to resume.
4. Archiving should start on specified days only... ETC...

Where do i see all the default tables and views in oracle 10g

hi,
I have installed oracle 10g in the linux os.
I just wanna see the list of deffault tables and views created by oracle.
can anyoone hlep me on this
thanx in advance....

Check DBA_OBJECTS for all seeded objects in an Oracle database. For tables, check DBA_TABLES. For views, check DBA_VIEWS. All of this is documented in the fine documentation - take some time out to read thru it.

Backing up all data and objects of Oracle 10g Express Edition...

Hi,
I have tables, packages, views, procedures, etc. in Oracle 10g Express Edition, running on Windows XP. I would like to create a backup of the complete database (objects, relationships, all data, etc) into a file that I can restore in case the database crashes.
What do I do?
Thanks.

I am actually using it for Production. Yes, I would need objects and data.I would suggest to look at the Standard Edition as well if you are using it for production.
Is there a way to backup everything without data and then backup everything with data? Also, is there a way to restore everything without data and then restore everything with data?What's the meaning of "backup everything withiut data" and "then backup everything with data" ? The data is in the tables alone. The rest of the objects are not containing data but are using it, be it views, procedures etc. There is no such restore like without data. Without data, all what you would be getting would be structures of the tables which is going to be of no use. The export/import tool, is a simple tool which can put the tables (and other objects as well) along with their data in your dumpfile . In the situation of loss of a table, you can do an import from that dump file and you can restore the table back(with or without data, depends on the choice of yours while running Import command) . But this is just going to be a logical recovery of the object(s). For a complete database, it's better to use RMAN which would copy the datafiles and keep it with itself. Later, when you have a crash, you can restore those files to get teh database recovered. But if you want complete security, its better to put your db in the archive log and then do the backup along with the archive log files.

Data replication and synchronization in Oracle 10g XE.

We are trying to do data replication and synchronization sort of thing for all our servers. We are using Oracle 10g. XE. I guess there are some features in oracle already for replication but I am not very sure about them.
To explain it more clearly - we will have individual database servers in our sub-divisions and then divisions and centers and then main server. We need to synchronize at various levels. So If any body is aware of any techniques, please let me know.

Hi,
Could you tell me what exactly synchronisation your talking about..?
we will have individual database servers in our sub-divisions and then divisions >>and centers and then main serverIf you have mulitple DB servers then you can connect it by DB links. also if you are talking DB synchronisation then you can have Triggers,Materialized views.
we also have two independent severs which are synchronised(atleast schema levels).

Pivot and Unpivot in Oracle 10g

Hi,
This is my table structure
CREATE TABLE TESTTABLE
REVENUE1 NUMBER,
REVENUE2 NUMBER,
REVENUE3 NUMBER,
YEAR DATE
insert into testtable(revenue1, revenue2, revenue3, year) values(100,200,300,'1-Jan-2009') ;
insert into testtable(revenue1, revenue2, revenue3, year) values(250,350,450,'1-Jan-2010') ;
insert into testtable(revenue1, revenue2, revenue3, year) values(300,400,500,'1-Jan-2011') ;
The resultant should be on oracle 10g.
The result should be like
1-Jan-2009 1-Jan-2010 1-Jan-2011
Revenue1 100 250 300
Revenue2 200 350 400
Revenue3 300 450 500
Thanks in advance

When posting formatted text (such as results) on this site, type these 6 characters:
\(small letters only, inside curly brackets) before and after each section of formatted text, to preserve spacing.
Column names are hard-coded into the query. To get variable data, such as '1-Jan-2009' as a column header, you must use dynamic SQL. This is probably best done in your front-end. SQL*Plus, for example, has substitution variables, that you can define with data from your table at run-time using the COLUMN ... NEW_VALUE command. (SQL*Plus also has a COLUMN ... HEADING command that can do what you want, , but it doesn't simplify this particular problem.)
What front-end tool are you using? Can you use SQL*Plus?

Trigger-Body isnt remaped during IMPDP and REMAP_SCHEMA in Oracle 10g

Hello,
we are facing the following problem:
During an IMPDP we are remaping the schema. The schema includes triggers. The trigger bodys are of normal syntax without a relation to the schema/user.
If we start the import with datapump using the remap_schema option the triggers are remap to the new schema. But the trigger bodys point to the old schema.
For example:
CREATE OR REPLACE TRIGGER "OLD_SCHEMA".NAME_OF_TRIGGER
BEFORE INSERT ON "OLD_SCHEMA"."TABLE_NAME" REFERENCING OLD AS OLD NEW AS NEW FOR EACH ROW BEGIN
END;
After using the REMAP_SCHEMA option:
CREATE OR REPLACE TRIGGER "NEW_SCHEMA".NAME_OF_TRIGGER
BEFORE INSERT ON "OLD_SCHEMA"."TABLE_NAME" REFERENCING OLD AS OLD NEW AS NEW FOR EACH ROW BEGIN
END;
So the Trigger Body in the NEW_SCHEMA uses a link to the OLD_SCHEMA and the trigger doesn't work. We wrote the trigger without referencing to a schema. So the OLD_SCHEMA resp. NEW_SCHEMA syntax must be added by datapump.
The question: Is there a way to remap the triggers correctly in the new schema or is this behavior "normal" to Oracle 10g Datapump?
We are using Oracle 10g Database 10.2.0.4 with the latest Patches on Windows Server 2003 SP2.
Thank you for you attention.

Hello,
I had the same problem and you can't fix it by changing a parameter of impdp. You really need to change the source of those triggers so they don't use hard-code schema references.
Solution would be to change the source code of those triggers. Or to use the "script" parameter of impdp and recreate the triggers yourself after the impdp has finished.
For more info check Metalink note: 750783.1
I hope this helps.

User name and password for oracle 10g

Hi Guys,
I downloaded oracle 10g and installed on my computer but when i try to work on SQL plus it's asking for an username and password, i tryed as scott/tiger,system/manager but unable to login please help me what to do...??

When u install Oracle 10g, it forces u to enter new passwords for System as well as scott user and it does not allow u to keep old know passwords as manager and tiger.
If u installed with new passwords successfully, u must be knowing those new passwords and there is no reason to try with system/manager. Instead try to connect with new passwords. We never faced such problems.
If the problems still persits, check that
a) Oracle service is running
b) Instance is running by and whether u are able to connect / as sysdba
