Server Administration :: Variable File Size For Archive Log Files
Dec 16, 2010
I'm facing problem with archive log file size, Archive logs are generated with only of 90m or 92m or 94m(Variable sizes of less than 100m), Although i had set 100m for each of my redo log file. Here i'm providing my create db script for your reference. I want to know why the log switches before it reaches 100m.Is there any connection of intial 10m for my .dbf files.
create database mydev
maxlogmembers 3
maxloghistory 100
maxdatafiles 50
maxinstances 1
logfile

We had a database (DB A)that is having version 9.2.0.6.0.This DB is having multiple tables and volume of 6 million in individual tables.Another database is also 9.2.0.6.0 (DB B), this DB has Mviews pointing to DB A. Mviews are refreshed in every 15 mins, with fast refresh option in 90% cases and remaining having complete refresh.
Last weekend we have migrated DB 2 to version 10.2.0.4.0 - 64bi and on another server.After version upgrade and DB migration complete refresh was done once for all mviews.
Now DB A is generating huge amount of archive log and also it's UNDO space is getting fully consumed causing performance issue and DB hang.what has gone wrong and what we can do to improve response of DB A and also to reduce size of Archive log ?

but we were not able to remove those .arc files from that folder. finally we have down all the instances and deleted those files manually.

1.2.0.2 on RHL.. 3 Log Groups with 1 member each. db_recovery_file_dest string /oracle/oraarch For the purpose of increasing log file size, if i use ALTER DATABASE ADD LOGFILE GROUP 1 SIZE 300M; but it creates Log Group with 2 member. one is at /oracle/oraarch location and other at /oracle/oradata (db_create_file_dest).
We are using ORACLE MANAGED FILE SYSEM . I want only 1 member at /oracle/oraarch (to keep the previous setting intact ...just increasing the size from 100 to 300M). If I manually give the path where to create the logfile member, I get this error:
ALTER DATABASE ADD LOGFILE GROUP 1 '/oracle/oraarch/DB/onlinelog/' SIZE 300M;
ALTER DATABASE ADD LOGFILE GROUP 1 '/oracle/oraarch/DB/onlinelog/' SIZE 300M

ERROR at line 1:
ORA-00301: error in adding log file '/oracle/oraarch/DB/onlinelog/' - file cannot be created

In normal days size of archives generated in a day is 14-15GB. But since yesterday morning, almost 150GB of archives have been generated and are still getting generated(200MB every 1-2 minutes).
There was a sudden reboot of server yesterday morning. At that time there was heavy load of transactions on database. Can it be a reason that smon is still doing recovery? (I am not sure on this). Also, Undo tablespace is increased from 18 GB to 50 GB since yesterday (autoextend on).
Now we are running out of space for archive file system (can't delete them also until they are transferred to DR) Size of redo log is 200MB. This database supports around 2500 users.
performance wise I don't see any hit. Also wait events are normal. (only few db file sequential read) finding the query/session which are causing this much huge amount of archives?

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 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.

What's the maximum size of the control file in one database ?
i calculated it according to the following steps:
SQL>SELECT (BLOCK_SIZE/1024/1024)*20000 MB FROM V$CONTROLFILE WHERE ROWNUM = 1;
MB
------
312.5
The maximum number of the data block in one control file is 20000.

Our database was generating archivelog(50MB) every 30seconds! I think this is not normal because what I did is open our database, I was the only one who is connected, I'm not running anything, but our database is still generating archivelogs!
Our redo logs: 6groups 3members.
This are the things I saw on our alert logs:
- advanced to log sequence
- cannot allocate new log, sequence
- checkpoint not complete
- private strand flush not complete
What I did is change the log mode of our database to noarchivelog then open the database, then returned it to archivelog mode then that fixed the problem. But the thing is after 6hours its abnormal behavior goes back again.

I need store history for two tables in my system. I thought that Flashback Data Archive will be the best option. There is also another ways to do this but don't focus on this. I need to to this by FDA (Flashback Data Archive);
So my prerequisite was to create tablespace and flash back archive, and alter table to be archived.
create tablespace audit_archive datafile 'd:oradata etaaudit_archive.ora' size 100M;
create flashback archive audit_flash_archive
tablespace audit_archive quota 10G retention 10 year;
alter table teta_admin.t_prac flashback archive audit_flash_archive;
and everything works fine but on sys user.
i can query this table using "as of timestamp" clause
select prac_id, imie, imie_2, nazwisko, nr_ew from teta_admin.t_prac as of timestamp to_timestamp('2011-08-23 08:20:00','yyyy-mm-dd hh24:mi:ss')
but final construction of idea was to create additional user (interface), grant select on teta_admin.t_prac object and query archive data from interface user. and this is point of my failure. this don't work on new user.
interface user have such sys privs:
SQL> SELECT * FROM dba_sys_privs
2 WHERE grantee = 'INTERFACE';
GRANTEE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
INTERFACE CREATE SESSION NO
and table privs:
SQL> SELECT * FROM dba_tab_privs
2 WHERE grantee = 'INTERFACE';
GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE
------------------------------ ------------------------------ ------------------------------ ------------------------------ --------------------
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN INSERT
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN DELETE
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN ALTER
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN FLASHBACK
INTERFACE TETA_ADMIN T_PRAC TETA_ADMIN SELECT
what i need to do in order to query this flashback table from interface user. when i try to do this from this user oracle says ORA-00942.

I have read it in books that flashback uses undo data to create the flashback data or to flashback the database to a time in the past.Then, what is the role of archive files in flashback operation. Why it is mandatory to turn on archiving before turning on flashback. Also, if you remove the latest archive files, you can NOT flashback the data to a time in past (Oracle complains of missing archive files).

I am running the following command to backup my archive logs and want to keep at least two hours of .arc files on disk.
rman < connect target login/password
connect catalog login/password
show all;
sql "alter system archive log current";
backup filesperset 5 archivelog until time 'sysdate-2/24'
format $FILE_DEST_ARCH
delete input ;
resync catalog;
EOT
On some occassions, there will not be any archive logs that meet this criteria and I get the following error:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

Is there anything I can do to the rman command above that will prevent this error from happening but yet keeping same functionality?

I am working to understand the space allocation of table with the value we provided with the data type. For that I have created a table with varchar2 and length 50. Size of table created is of 65536 Bytes. This is when we don't have any insertion in the table. Later when we insert some rows, total size if the segment still remain same that is 65536 bytes.
Now again when I created table with varchar2 and length this time is 500 but still it is created with same size that is 65536. So can you just explain, on what values segment size depends on and how the length effect the size & space allocation.
db_block_size is 8192.
