Mar 6, 2013I have one procedure which is executing daily two times(i.e morning run and evening run) . In morning run it's executing around 150 mins and evening run executing around 25 mins.
It's happening for all procedures executing in longer run in morning. There is NO LOCKS, I have checked LOCKS while executing morning run. I suspects CPU usage in morning run.
How to check CPU usage ? AND also each session how much utilizing CPU. I'm using oracle 8i database, I know it's older version but my company is using oracle 8i. So i have to look in this database version only.

Nov 13, 2010In OEM10 I can click on the database size in the database page. When I do this I am redirected by the OEM to teh Database space usage report.
I have 3 questions about reports in OEM10g:
1. Can I create drill-down reports in OEM10g?I want to create a report that shows the space usage per host and drill down to the databases (targets) that are on that host.
2.Can I create a link to the Database space usage report? I would like to redirect to the report from the report in question 1 from a target. So that I can see the space usage of the database that was selected.
3. Can I create a copy of the Database Space Usage summary report that the OEM shows? I can't find it in the report tab of the OEM.

Reclaiming Actual Physical Disk Space
Sep 2, 2011I look after a team of DBAs and I have a request to free up space on our very expensive storage system. However the answers on how to do this differ and i'd like to ask for external input...So not being a techincal person I see the world as quite black and white. Meaning that you delete data and you free space but after doing much reading I understand this is not the case, as you essentially create data fragmentation within the datafile resulting in the db having lots more space to write into but not actually freeing space, even if you shrink the file it doesnt free space or do a reorg?
We have as an example a DB with 2 billion rows of data in 1 table, no partioning just one large table. We have worked out that we can probably delete 1 billion rows or even better only keep a rolling 3 month window of data. What would be the suggestion on deleting this data and reclaiming the disk space to actually see additional disk space made available at the os level.
How about deleting the data and reclaiming the space. Through reading it looks like it might be something like, delete, creating new table space partitions from this data. This in theory would create new a tablespace in newly created data files which would result in the data being reorganised and taking up less physical space and when completed you point to the newly created partitions and drop the old tables.
how they have done this as it must be a common problem that people have created some different solutions. What commands, procedures have been used?

RAC/ASM Clusterware Installation :: Checking Free Disk Space On OS And ASM Bug?
Jul 9, 2012I've installed GI 11.2.0.3 on AIX 7.1.And today I noticed strange ASM's behavior:
-bash-3.2$ getconf DISK_SIZE /dev/rhdisk2
*2285768*
-bash-3.2$ asmcmd
ASMCMD> lsdsk -k

*188616* 68204 *188616* DATA_0000 DATA_0000 REGULAR System UNKNOWN /dev/rhdisk2
I guessed that was because of LUN size (it was exceed 2 TB)After that I dinamically shrinked LUN size on our external storage, rebooted and perfomed cfgmgr command on both nodes. But I still have no enough free space.
-bash-3.2$ getconf DISK_SIZE /dev/rhdisk2

View 2 Replies View RelatedSQL & PL/SQL :: Find Total Space Occupied On Disk By Tablespaces Of Database
Nov 3, 2010I am trying to find the space occupied on disk by the tablespaces of the database that contain tables, some (and not all) of whose columns are encrypted. My query is like this:
select distinct a.tablespace_name, file_name, bytes /(1024*1024*1024) File_Size_In_GB
from dba_data_files a, dba_tables b,
(select distinct owner, table_name from DBA_ENCRYPTED_COLUMNS) c
where
a.tablespace_name = b.tablespace_name and
b.owner = c.owner and
b.table_name = c.table_name
order by a.tablespace_name;
The output of the query is as shown in the attached file:
TABLESPACE_NAMEFILE_NAMEFILE_SIZE_IN_GB
DMS_DATAM:ORACLEORADATASPOPRODDMS_DATA_0044.DBF29.296875
DMS_DATAM:ORACLEORADATASPOPRODDMS_DATA_0045.DBF29.296875
DMS_DATAM:ORACLEORADATASPOPRODDMS_DATA_0051.DBF29.296875
DMS_DATAN:ORACLEORADATASPOPRODDMS_DATA_0012.DBF19.53125
[code]...
Since the output (under the heading Total Size of the tablespace) is probably the sum of all the datafiles returned by the query and is obviously incorrect, I have not given the rest of it. I also tried the following:
select distinct a.tablespace_name, file_name, bytes /(1024*1024*1024) File_Size_In_GB,
sum (bytes/(1024*1024*1024))over (partition by a.tablespace_name order by file_name) "Total Size of the tablespace"
from dba_data_files a, dba_tables b,
(select distinct owner, table_name from DBA_ENCRYPTED_COLUMNS) c
where
a.tablespace_name = b.tablespace_name and
b.owner = c.owner and
b.table_name = c.table_name
order by a.tablespace_name ;
[code]...
Here, the fig. under the heading "Total Size of the tablespace" are probably the sum of all the records returned by the query if distinct is not used i.e all the data file sizes returned by the query.
tune my query and get the desired results? I think this can be achieved by group by with rollup, cube, order by and grouping functions, but am not sure how to proceed. I know that I can get the results by using Enterprise Mgr. Console in 2 mins., but would still like to get the results with the queries.

View 1 Replies View RelatedServer Administration :: Any Relation Of Tablespace Disk Space And Actual Data Present In Tables
Aug 16, 2012We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?

Adding ASM Disk With Header Status MEMBER To Existing Disk Group
Aug 26, 2010We have a Production Oracle 10g R2 RAC on HP-UX v2 IA64 servers.We have Two Disk Groups one for Archive (ARC_DISK - 100 GB) and other for Database(DATA_DISK - 1 TB]. We wanted to add more space to the DATA_DISK disk group.Unix admin configured 200 GB from SAN and changed the ownership of the Disk to oracle and permissions to 775 on 1st Node.I opended DBCA from 1st Node and was able to see the disk in 'Show Candidate'.
I added this disk to the DATA_DISK disk group and clicked OK but got ORA- error with some message like some operations could not be performed. I exited DBCA.We realized that we had forgotten to change the ownerhip and permission from the 2nd Node.Unix admin changed the ownership of the Disk to oracle and permissions to 775 on the 2nd Node.
I opened DBCA again from 1st Node and selected the DATA_DISK disk group but could not find the Disk in 'Show Candiate' open. I clicked on 'Show All' and this disk was shown with Header_Status - MEMBER but not allocated to DATA_DISKGROUP. When I clicked the 'Show Member' option, this disk is not shown for DATA_DISK disk group. I exited DBCA at this point.As this is a critcal Production database I didnt proceed any further and exited DBCA.
Now I need to add this Disk to the DATA_DISK disk group but not sure which option to select. I got one reply from another forum to run DBCA select the DATA_DISK Disk Group and then click 'Show All' and select this Disk (which already has MEMBER as Header Status) and select Force Option and click OK to continue.
Server Administration :: Disk Group With Two Disk For Normal Redundancy
Jan 16, 2013I Configured an ASM instance and a disk group with two disk for normal redundancy.
> Here .. each disk is 2gb
The disk group has two disks...
SQL> select group_number, name, type, total_mb, free_mb
2 from v$asm_diskgroup;
GROUP_NUMBER NAME TYPE TOTAL_MB FREE_MB
------------ ------------------------------ ------ ---------- ----------
1 DATA NORMAL 4000 3898
as the group has two way mirroring (Normal redundancy) How much data (2 GB or 4 GB) can i keep in the disk group? My conception is I can keep 2 GB data in the disk group... (as the disk group keeps every extent in another disk as mirror)

In other words, when the publisher is notified of a record change and sends the record to the staging area then calls the subscriber. Is the subscriber that runs the ETL logic that processes the record before it is sent to the DW/Dim tables? Something like this flow:

After enabling /3GB switch parameter in Boot.ini file, the OS recognizes the 8GB RAM and consumes it upto 5.6GB during non-peak hours but as workload increases in evening when end users generate auto receipts the same memory usage ratio reaches upto 6GB resulting the OS gets hang and don't respond at all. Inspite of having 2GB free memory it doesn't consume it. We have to shut down it by pressing the power off button and restart it
