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

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.
I had created a Primary key and wanted to compress as per my senior instructions.Below are my results the size increased after compression.
select compression from dba_indexes where index_name = 'TEST_IDX'; Compression ---------- DISABLED select sum(blocks) no_of_blocks, (sum(blocks)*8192)/(1024*1024)size_MB
[code]....
We ran a compression on the primary key index TEST_IDX
ALTER INDEX SCOTT.TEST_IDX REBUILD INITRANS 15 TABLESPACE DATA_01 COMPRESS; ANALYZE INDEX SCOTT.TEST_IDX VALIDATE STRUCTURE;
Now when i ran the below select statement:
select compression from dba_indexes where index_name = 'TEST_IDX'; Compression ---------- ENABLED select sum(blocks) no_of_blocks, (sum(blocks)*8192)/(1024*1024)size_MB
[code]....
As you can see after compression the blocks and size has been increased, but i ran for many tables and other indexes, we observed the blocks and size was reduced by 50-70%, i am not sure why this happened to the index compression.
I want to increase the size of the tablespace but when i login as sysdba or admin user i can just see the 21 tables in the dba_tablespaces or user_tablespaces. I want to see the tablespaces related to the application.
The size of redolog member is 12m . Can I increase the size of that member dynamically, without adding a new member to that group and dropping the old one.
How can in increase the allocated space for a schema in Apex Admin section?
I know you can set this when creating a schema alongsite a workspace and looks like the only way to do it is via raising a service request for more space and loggin in as ADMIN and approving it (in increments of 500MB).
I noticed that listener file in diag/trace is rapidly increasing. I am using 11g Rel 1 on window 2008 server Its 1 GB in couple of days. Is there any way if I can turn it off ?
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 ?
i am using oracle 10g on solaris 10 os.currently archived log is generated by size wise 52 mb.i want to know whar is the best practice for archive log generation . it should be time interval or size wise.
I am in need to find archive log mount point space detail usage through sqlplus on multiple instance. Is there any view in oracle which can give me the detail.
I know one method using external table but that is cumbersome for RAC.
can i get some command like this.
select inst_id,mountpoint,space_usage,space_available,total from GV$table --> returns
I am not able to delete one month old archive log file on production database. it already applied on standby database. While deleting the files, it throwing errors as "Another program is using it".
I am not able to delete one month old archive log file manually on windows which doesn't having info about the standby on v$archived_log view of primary database. the sequence were already applied to the standby database. It shows the status as deleted in v$archived_log. while deleting the file manually. it showing an error like another program or person is using it.
I have configured data guard in the windows XP same server .It is not able to apply log to the Standby database.when I queried the following, I go the following erros..
We are facing a different issue in our database. From yesterday night, the archive log generated with 5 digit. But it supposed to be 6 digit. Hence we are not able to apply the logs in DR Location.
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'm using Oracle10G (10.1.0.2) Enterprise Edition. The size of the listener.log file approximately 2.46GB. Is this responsible for any performance problem of any service in my current instance...
I am getting the following error when i try to re size the data file.But the data file is having lot of free space.
ORA-03297: file contains used data beyond requested RESIZE value
Presently table space size is 220GB with 8 data files.As the process of the performance tuning we moved data to different table spaces.Now used space of the tablespace is 90GB.So I am trying to resize the datafile but it throw an error.
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?
The REDO log file size is important DB performance issues when DB is run archivelog mode.If DB run noarchivelog mode, REDO log file size not impact to DB performance.
we have an environment with many Oracle databases in different versions (v8, V9, V10 and V11). Besides that, there are many versions of the Oracle Client in use, ranging from V6 to V11. Many of the clients have a TNSnames.ORA and as was to eb expected, many of these are old as well with a lot of (by now) invalid information in there.
Is there any reasonable maximum size to the TNSnames.ORA file?What are the consequences from going over the max size? Are there alternatives to using TNSnames.ora which you would recommend?
I have a standalone DB of version 10.2.04.I am facing log file parallel write as one of the top events.I have increased the REDO log file size to 500m.But even then REDO switching is happening frequently.

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.
I am having I/O issues if i create 20 GB DATAFILES on SMALL TABLE SPACE. guide me with the maximum size limit of data file that I can create in Windows 2003 32 bit server.
