i want to know the backend process of Oracle DB.because when ever we are taking about DB , so many things are coming into pictures like Physical,logical structures,instance,schema,servers,storage and all. Actually i know what is oracle and why we are using that .
View 4 Replieswe have a very critical application running and the backend database is 10.2.0.3. we are planing on upgrading to 10g to 11.2.0.2 and looking ways to look with minimal downtime off production. steps for upgrade with very minimal downtime of appliction?
View 2 Replies View RelatedThere is a report that is generated everyday in the .csv file format that i would want to load into the database. I want to completely automate this process. I don't want to use the load function available in APEX. I use APEX 3.2 Version.
What i mean by automation is that i will create the CSV file and automatically move to a location from which APEX can access the data. I would then write a procedure to fetch the content directly from CSV file and write to the database. What i need is the location from which APEX can access data directly ?

We are in the process of setting up a DR environment for our SAP and Oracle databases . The netapp and our architects came up with solution as follows .
1.Standby databases are built for all production databases.
2.The SAP file systems are replicated to the secondary site
3.The Oracle logfiles and controlfiles are replicated by netapp snap mirror every 10 mins interval
4.The database is recovered through recover standby database every 15 mins at standby site
5.Please note there is no data guard involved .
6.To test the failover , the mirror is broken .The standby controlfile is replaced with Production controlfile and Redo logs files.
7.The standby database issued a startup comnmand and it worked .
Would like to know whether the step 6 is a correct approach ? I tried to convince the architects that this will result in a very disastrous situation for us but none is listened to .
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID,
SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM,
SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID
FROM
SYS.GV_$PROCESS, SYS.GV_$SESSION
WHERE
SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST'
and SYS.GV_$SESSION.MACHINE like '%hostname%'
I Created a form just for testing purpose [Which is i attached]
My Table is TEST0
Structure of table :

FLG VARCHAR2(1)
My Task is When i added a record, e.g if on form, i add name - AAD But its must save on TEST0 Table like this way EMPAAD...means always concate with 'EMP'||:Block.name while saving on database..
I know how to do with front end application, but i want to achieve this task by using trigger on backend databse...how to create a Trigger on backend....i try a one trigger but it give me error- Unable to insert Record...
Name some database tool from which I can check the SQL Queries which my application is running.

Which server process is used in the oracle 11g Production? if the database is connect to an online application?
Currently maximum process is set to 150 in one of the RAC database. What should we do if the current session is about to reach maximum process or has exceeded the max process.

A client of us has given us a new requirement to write batch extracts from an operational database. While that per se is not the issue it is the peculiar circumstances that have made it a bit of head ache.
i. The database is an operational system (for telco billing)
ii. THe data from key tables of events etc. has to be replicated to downstream systems like the data warehouse, reporting areas etc. every 15 mins.
iii. Needless to say there are about 50 million records to unload from the table.
iv. The tables are partitioned and tuned for operational purposes.
v. The dba are a bit touchy (surprise!) about persons accessing their db directly for unloads
vi. There is no stand by or replication from this database
So, given the above what would you experts recommend as an option. We had recommended a golden gate based solution however that has is thought of long term solution as it will involve purchases and some POC. Would be grateful if persons can enumerate options, tools, 3rd party options or oracle design solutions .

I have a test server that keeps running into ORA-00020: maximum number of processes error each night. Our current setting is '600' processes to be allowed. There are no users to this database except myself. No front end app connects to it either.
I found that ORACLE.EXE (SHAD) process coming from SYSMAN user is the one eating up all the processes and eventually causing that error.
From v$session, the program is OMS.
From v$process, the hostname is the server itself.
I narrowed it down to restarting the ConsoleService, if i do that, then the number of processes drops down. So now im not sure why something within the ConsoleService is logging in, taking a process and not releasing it...What i can check?

View 1 Replies View RelatedI got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site
Need to use same query to decode and then use data based on the lower between clause to show
WITH DATA AS (select tb.address_id,DECODE(tb.month,
'1', '01',
'2', '02',
'3', '03',
'4', '04',
'5', '05',
'6', '06',
[Code]...
Output should come from the inner query only where between condition works..
so we should see only those addressids for 10-2009 to 11-2009.
