i have install 0racle 9i its working fine .I can access data from launch standalone but when i tried with login to oracle management server i can't login .
how can login with oracle management server .
when i want to do backup in oracle management server for my database (repository)that i created give me an error message
<< using perferred credentials , the following error occurred: ORA-01031 :insufficent privileges>>
I have been reading various articles about the undo management. This basic concept of undo management is simple but how oracle implements it is bit harder for me to grasp.
What i have read and understood is that whenever a DML(Update, Delete, Insert) statement is issued by a user, the data is fetched from datafile to database buffer cache and at the same time a copy of the original data is saved in undo segment. Now if other users requests the same data, they are presented with the unchanged copy in the undo segment.
Now I have the following questions:
1) In case of Insert statement, what data is saved in undo segment. Is it the complete data in the table to which we want to insert the new row?
2)When the user issues DML statement, there are three copies of the same data, one in Memory (which is changed and not the same as original data), second in Undo segment (Which is unchanged copy of original data) and third in datafile file ( which is original data). What is the difference in the data in undo segment and data in datafile at this stage. Why are the other users presented with the data from undo segment rather than original data from the datafile to maintain read consistency.
3)When the user issues rollback, the changes made to the copy of data in memory are undone.The copies of data in memory and undo segment are now same?. What happens to the before change copy in undo segment. Is it still there or deleted.
I have installed executable only (database option only) when i have installed oracle11 that time it is not asking any option for password. So is there any option to login in this type of condition?

View 9 Replies View Related am using Oracle 10.2.0.4 on win 2008 server SP2. I would like to know if we can set the Segment Space Management feature to AUTO for RBS and Temporary tablespaces. As the data is not permanent in these tablespaces, will it manage automatically?
Presently its Segment Space Mgmt is manual for System, RBS, Temporary tablespaces.
I have read this article:

And i see:
Quote:
If MEMORY_TARGET is set to non zero value:
SGA_TARGET, SGA_MAX_SIZE and PGA_AGGREGATE_TARGET are set to 0, 60% of memory mentioned in MEMORY_TARGET is allocated to SGA and rest 40% is kept for PGA.
So, I have set:
alter system set sga_target=0 scope=spfile;
alter system set pga_aggregate_target=0 scope=spfile;
alter system set sga_max_size=0 scope=spfile;
alter system set memory_max_target=512M scope=spfile;
alter system set memory_target=300M scope=spfile;
, and then bounced the instance.
After startup, I see:
SQL> startup
ORACLE instance started.
Total System Global Area 272027648 bytes
Fixed Size 1384012 bytes
Variable Size 100663732 bytes
Database Buffers 163577856 bytes
Redo Buffers 6402048 bytes
Database mounted.
Database opened.

But Total System Global Area should't be in that case 60% of memory mentioned in MEMORY_TARGET? Memory mentioned in MEMORY_TARGET was 300M, and 60% of 300M is 180M, which is not 272027648 bytes.
I just want to use automatic memory management, so I've set the other parameters above to 0. My instance is on my local machine, so just for my own personal use.
the syntax to make a tablespace's segment space mnagement auto which is segement management is *manual* and exent management is *local autoallocate*.

I am trying to understand how to enable some audit so we can capture OEM logins as well.
Here is my setup. Lets say my DB that i am auditing is called audit_db (audit trail set to DB) sitting on host called host_db. and we have grid control agent on this box.now my grid control is as this. Lets say my OMS and repository is on host called OMS_host.
we run query aginst dba_audit_session to get info as to who tried failed login attemps and stuff.
Now to the part that is not working.
-- this is the good part When i intentionaly login to the audit_db with sqlplus client from my laptop with wrong username/password that is captured. we get the username,os_username,userhost,terminal.
here is the sample output
username is the wrong user that i tried to login as
os_username is the my local username(ad account)
userhost is my_laptop_name
terminal is laptop_name
from above we can figure who was trying to login(failed).
-- this is the bad part But lets say i try to login to audit_db through grid control and use wrong username/password.that gets captured too(but not all of it). we get the username,os_username,userhost,terminal.
here is the sample output
username is the wrong user that i tried to login as
os_username is the user of OMS repository db(oracle)
userhost is oms_host
terminal is unknown
Now with the above info, we cannot figure out who tried to login with bad login credential.
I have one generic question about space management. I have one table with size of 1TB. This table stored in ORC1 tablespace. This tablespace contains 70 datafiles.
Since it's 10.2.0.4 database. I have dropped this table by using purge
drop table <<table_name>> purge;
Once table drop was completed. When I check the tablespace space it was 100% free but due to HWM was unable to resize the datafile from current size to small size. What was the reason behind this. Is there any process needs to follow when dropping big tables ? like instead of dropping the tables do I need to truncate first & then drop .
I have one tablespace called U01. This tablepspace contains 31 data files. Due to high water mark I was unable to most datafiles. Since my database running onair application they will not provide me downtime to move the tables. Is there anyway to fix the high water mark without getting downtime window? almost 700+g space unused. I need to reuse them asap because running out of space with in asm diskgroup.
