My archivelog database get error because my flash_recovery_area is full.
so I disable archivelog mode. When to restart database server I got this message:
ORA-03113: end-of-file on communication channel
processus ID : 27427
session id : 96, Numéro de série : 3
Do you think I can delete manually ( Os commande rm ) files in flash_recovery_area ?

We are running Oracle 11.1.0.6 on CentOS Linux at our local network. Two dozen users work from client's network to access this database. There are firewall and switches between the local network and client network. Everything run smoothly for last two years until about 10 days ago, something changed. The client on the client's network can still connect to this database, but they can not run large queries. Their client connection hangs and time out. I can see TNS-12535: TNS:operation timed out and TNS-00505: Operation timed out in the alertlog file. They even had problem to load stored procedures and views onto TOAD from your PC. All the user on the local network can work on this database normally.
We consulted network team and firewall team, none of them said they make any changes recently and have no firewall rule or others to block the traffic.
I have a strong feel that this is a network related problem. But don't know how to provide solid evidence to make network people/firewall people to buy it.
You can connect to the database but can't run query on large table/view?

The problem concerns distributed transactions.There are 2 databases that communicate with each other through a database link.We call Xa transactions from our weblogic application. Both databases work in a shared server mode.
Everything works until we run some performance tests on the evironment where the data volume is much bigger then the one on the other environments where the same tests succeeded. We're getting the following error: ORA-03113: end-of-file on communication channel
The error get registered in a local database alert.log when accessing data through the database link while there's no trace corresonding to this error as far as the second database is concerned. We're almost sure there's no network problem. The error occurs in only 1% of a total executions number. We also observe the inactive sessions number increasing on the remote database.
Both databases use ASMM by having set the SGA_TARGET and PGA_AGGREGATE_TARGET parameters and proper level of the STATISTICS_LEVEL parameter, so some hot elements like SORT type operations should execute fine.Any Oracle parameter should be tunned or we should take into consideration something else...

I have a question ragarding undo tablespace. I want to ask that why only undo tablespace information we need to specify in parameter file. We do not specify any other tablespace information. Not even for temporary tablespace. Then why we need to give undo tablespace name while instance is creating.

I noticed my DB is generating a lot of "small" .arc files and I am usure why. As you can see from the v$log query my log file size is set to 50MB. But yet BLOCKS*BLOCK_SIZE never adds up to 50MB.
Is there anything else I can look into to see how to make the .arc files larger?

I am trying to create a new controlfile. I used "alter database backup controlfile to trace;" and then I copied and pasted the contents of the trace file into the .sql file. My sql script is
CREATE CONTROLFILE SET DATABASE "FIVESTAR" RESETLOGS NOARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292
[code]....
Actually, the name of my database was 'STAR' and I changed it to "FIVESTAR" int this .sql script. Now when I run this script with SQL> @ <path of my sql script>, it gives me the following errors:
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed

redo generation. As I found the below statement in another forum."Undo segment generates the redo data also, because undo segment is database changes, so it generates the redo data also."
How a Undo segment can generate Redo and Undo datas.

I was doing some R&D on my test machine trying to understand how controlfile works. I started up my db and then deleted (renamed)the controlfiles at OS level. I was expecting the db to shutdown. But it dint. Moreover when i queried select name from v$controlfile; it was still reflecting the old controlfile names. To check if it was still functioning, i created a new tablespace with one file and it also got created without any error.
What i dint understand is how could the db still be running when the control file was'nt there and new tablespace and datafile get created? As i understand, whenever a new file is created, an entry is made in the control file. But when control file dint exist where was the data about new tablespace and datafile written?

I mistakenly added a datafile to a tablespace which is asm, however the datafile was created in a default location and not the asm location:
alter tablespace pdaiidata1 add datafile '<filename>' size 2048M;
What I should have done:
alter tablepsace <tablespace_name> add datafile '+DATA1' size 2048M;
Is there any way to move this filesystem datafile into the asm tablespace? In previous Oracle versions, I've taken a tablespace offline, moved a datafile, renamed it, then brought the tablespace back online. Can I do something similar here in this situation?

I am storing customer's snaps in a table ( column's data type as LONG RAW) using oracle forms Webutil. Now there are 250 snaps in the table. The file type of these snaps is JPG with the average size 30KB.
I made a backup using export utility before storing these snaps and the exported DMP file's size was 36MB. Now after storing these just 250 snaps of 30KB the DMP file's size is gone over 300MB.
i need to change column's datatype? or some where in oracle forms's image item. Because on window's file system the size of these files is just 8MB.
