Reduce the backup time

We have a very critical system, where the down time of the system is counted. We need t minimize the downtime of the system when it need to be stopped. Most of the downtime come when we are doing backup for oracle before shutdown.
the question is:
what is the best practices to minimize the backup as much as we can,
I will give an example of some idea came, but we are not sure if it works, We take the backup at 1:00PM without stopping the transaction then after stopping all the transactions we take anther backup only for transactions after 1:00 PM, dose this scenario works, or is there any other scenario that can help?

>We take the backup at 1:00PM without stopping the transaction then after stopping all the transactions we take anther backup only for transactions after 1:00 PM
Do you have documented reason for this ? Is the database running ARCHIVELOG mode ? How do you take the 1pm backup ? Using RMAN ?
Oracle RMAN (with the database in ARCHIVELOG mode) is designed to allow online backups of the database (you must also backup the archivelogs !!).
I suggest that you review the Oracle documentation and/or take an Oracle training course in Backup and Recovery.
See either of :
http://docs.oracle.com/cd/E11882_01/backup.112/e10642/toc.htm

REDUCE THE BACKUP TIME/RMAN

I am taking full backup every week end. But its taking a long time to complete as size of database is very big. Is ther any way to do backup fastly as parrallal processing . We are using RMAN. Kindly tell me some way.

Kindly tell me some way.SEveral methods in the rman guide (see tahiti.oracle.com) and also in "Oracle Database RMAN Backup & Recovery" by Hart and Freeman (Oracle Press). Depending on your needs, a couple of things come to mind immediately, and they are not mutually exclusive:
1 - take a full (incremental 0) backup only once a week, with incremental (incremental 1) backups the other 6 days.
2 - backup only a subset of your tablespaces each day - different subset each day.
3 - implement change tracking, so rman only backs up blocks that have actually been modified
Also be aware
- you don't mention down time ... are you taking a cold backup? Are you aware that rman can do a hot backup, so you don't have to stop the database? Performance impact is usually pretty minimal.
- you must be in archivelog mode for any of the above.

How do I change my iTunes settings to lower the resolution of movies I download to reduce the download time?

If you're buying HD movies, you can change the setting in the Store preferences in iTunes to prefer 720p. Or you can just buy SD versions.

Reduce the execution time for the below query

Hi,
Please help me to reduce the execution time on the following query .. if any tuning is possible.
I have a table A with the columns :
ID , ORG_LINEAGE , INCLUDE_IND ( -- the org lineage is a string of ID's. If ID 5 reports to 4 and 4 to 1 .. the lineage for 5 will be stored as the string -1-4-5)
Below is the query ..
select ID
from A a
where INCLUDE_IND = '1' and
exists (
select 1
from A b
where b.ID = '5'
and b.ORG_LINEAGE like '%-'||a.ID||'-%'
order by ORG_LINEAGE;
The only constraint on the table A is the primary key on the ID column.
Following will be the execution plan :
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=406 Card=379 Bytes=2
653)
1 0 SORT (ORDER BY) (Cost=27 Card=379 Bytes=2653)
2 1 FILTER
3 2 TABLE ACCESS (FULL) OF 'A' (Cost=24 Card
=379 Bytes=2653)
4 2 TABLE ACCESS (BY INDEX ROWID) OF 'A' (Co
st=1 Card=1 Bytes=6)
5 4 INDEX (RANGE SCAN) OF 'ORG_LINEAGE'
(NON-UNIQUE)

I order it by the org_lineage to get the first person. So it is a result problem? The order by doesn't give you the first person, it gives you a sorted result set (of which there may be zero, one, or thousands).
If you only want one row from that, then you're spending a lot of time tuning the wrong query.
How do you know which ORG_LINEAGE row you want?
Maybe it would help if you posted some sample data.

Keep in mind that Logic also has a limit of 8550 quarter notes. So changing the time signature to 4/8 can get longer recording times. So make sure you change this setting along with the song end. See page 93 in the reference manual.

<b>Optimizing the load of the database</b>
For all entries
The for all entries creates a where clause, where all the entries in the driver table are combined with OR. If the number of entries in the driver table is larger than rsdb/max_blocking_factor, several similar SQL statements are executed to limit the length of the WHERE clause.
The plus
Large amount of data
Mixing processing and reading of data
Fast internal reprocessing of data
Fast
The Minus
Difficult to program/understand
Memory could be critical (use FREE or PACKAGE size)
Some steps that might make FOR ALL ENTRIES more efficient:
Removing duplicates from the the driver table
Sorting the driver table
If possible, convert the data in the driver table to ranges so a BETWEEN statement is used instead of and OR statement:
FOR ALL ENTRIES IN i_tab
WHERE mykey >= i_tab-low and
        mykey <= i_tab-high.
Nested selects
The plus:
Small amount of data
Mixing processing and reading of data
Easy to code - and understand
The minus:

The plus
Very large amount of data

Optimizing the load of the database
Using table buffering
Using buffered tables improves the performance considerably. Note that in some cases a stament can not be used with a buffered table, so when using these staments the buffer will be bypassed. These staments are:
Select DISTINCT
ORDER BY / GROUP BY / HAVING clause
Any WHERE clasuse that contains a subquery or IS NULL expression
JOIN s
A SELECT... FOR UPDATE
If you wnat to explicitly bypass the bufer, use the BYPASS BUFFER addition to the SELECR clause.
Use the ABAP SORT Clause Instead of ORDER BY
The ORDER BY clause is executed on the database server while the ABAP SORT statement is executed on the application server. The datbase server will usually be the bottleneck, so sometimes it is better to move thje sort from the datsbase server to the application server.
If you are not sorting by the primary key ( E.g. using the ORDER BY PRIMARY key statement) but are sorting by another key, it could be better to use the ABAP SORT stament to sort the data in an internal table. Note however that for very large result sets it might not be a feasible solution and you would want to let the datbase server sort it.
Avoid ther SELECT DISTINCT Statement
As with the ORDER BY clause it could be better to avoid using SELECT DISTINCT, if some of the fields are not part of an index. Instead use ABAP SORT + DELETE ADJACENT DUPLICATES on an internal table, to delete duplciate rows.
Good Luck and thanks

I am trying to confirm the time at which a particular backup occurred using an external hard drive that I have since misplaced. Although time machine lists the backup times for some backups, it does not list them for all. Can someone help?

I am trying to confirm the time at which a particular backup occurred using an external hard drive that I have since misplaced. Although time machine lists the backup times for some backups, it does not list them for all, including the one in question. Can someone help?

Okay, I've sussed it. I saw a link to another discussion that hadn't turned up in any of my searches before I posted the question above.
My Tosh HDD was formatted to FAT 32 and therefore would not be backed up by Time Machine. I removed all data from it - nightmare as I hadn't enough space to put it on the macbook HDD, but, after trawling through numerous photos and deleting rubbish for hours, I finally made enough space and copied all data across. Then, after clearing the data from the Tosh HDD, I used disk utilitity to reformat it to Mackintosh OS Extended. Chose the option without kournalling because I'm not baking up onto this disk and so don't need it - according to some other discussions I found.
When it was done I check on time machine in system prefs and once I selected options, I was able to remove it from the excluded from backups list. Hey presto. Now I'm moving my photo library and my music library onto the Tosh HDD and my macbook should start to breath again. Hurray.

Can I reduce the execution time for a step in a TestStand ?

Hi,
I calculated the a single step execution time for TestStand Ver 2.0. It comes to around 20 milliseconds/step. Can I reduce this excution time ?
Are there any settings available for configuring execution time parameters except result logging and exception handlings to reduce the execution time ?

It's difficult to tell how you what time you are reporting for your step. Clearly we don't have control of the time it takes your code to execute. However, we are constantly working on reducing the overhead of calling the code. In addition, you don't mention the type of step you are calling. One way to have a common reference is to use the example \Examples\Benchmarks\Benchmarks.seq. Below have have posted the results of running this sequence with both tracing and result collection enabled and then disabled. I have a 700 MHz, 128 MB RAM, Dell PIII laptop. In this example there is no code within the code modules. You notice that calling a DLL has the least overhead with a minimum of 7.459 ms with tracing and results enabled and 0.092 ms with tracing and results disabled. Although not included below, if I enable results be disable tracing I get a minimum time of 0.201 ms, a 100x improvement on your time.

How to reduce the cloning time if using cold backup?

Hi,
We are using EBS r12 (12.0.6) with database 10.2.0.3 in Linux Redhat 4 32-bit envoirnment.
Our datbase size is around 480 GB and we are facing the issues to provide the clone to my consultants for meet the target timelines in given time.
(Source:)---- Production Dell R900 Server machine having 32-GB RAM and 8 Quard Core CPU's.
(Target:)---- Clone Dell 2950 Server machine having 16-GB RAM and 4-Quard Core CPU's.
Currectly we are taking cold backup like:
1: Auto shutdown EBS r12 database nighthy at 12:00 AM daily and compress the backup using tar utility in linux. This process takes 6:00 hours aprox:
2: After that we move compressed file to clone machine and then uncompressed it, and this process takes 5:00 hours aprox.
3: And performe standard cloning steps.
Questions:
1: How to reduce time of this backup process?
3: Is there any other way to reduce the cloning process.
2: What type of backup oracle recommended to their customers for this type of process?
Thanks.

1: How to reduce time of this backup process?Without using third party tools, it might be hard to tune the timing of compressing/uncompressing the file.
Have you tried to use scp command? This would help if your network throughput is acceptable.
3: Is there any other way to reduce the cloning process.Since the main issue you have with the copy, then you might copy the files remotely from the source to the target, or using any other storage/backup tools (like file system snapshot).
2: What type of backup oracle recommended to their customers for this type of process?Oracle does not recommend any type of backup as the tools used are not Oracle products.
Thanks,
Hussein

HT201250 How do I reduce the 'Backups' Data on my Macbook HD and how to reduce the parameters of Time Machine?

My Macbook Pro is using 320GB on "Backups" and Time Machine is using 640GB. It just seems ridiculous, considering I everything else only takes up 77GB combined. How to I get rid of a good chunk of it from Macbook HD and also how can I reduce the Time Machine parameters, maybe so it starts deleting back up data sooner?

If you run TM you don't really need local snapshots so if you need the disk space you can disable them in Terminal by copying & p;asting this command at the prompt
sudo tmutil disablelocal
Press return. You will be prompted for your password, it will be invisible.
To undo this, rerun it with "enablelocal" instead of "disablelocal".
In TM preferences you can choose to exclude items to the backup.
EDIT: See these helpful hints from Pondini.

Is there a way to reduce the backup frequency to iCloud

I got a email from my ISP yesterday notifying me that I had used 14GB of my plan this month. As the new billing cycle only started this week i realised something was not right so i began to check my useage level for each day only tho find that it was consistantly high each day. I then began looking at the history and discovered that my useage spiked when i purchased my iPhone 4S. So i looked at the settings and discovered that my Storage allowance on iCloud was already nearly full and the next backup was going to be 5GB as it was backing up my iPhones Photos. Seeing as the phone seems to be backing up each night when i plug it in to charge, is there a setting to reduce the frequency that backups are performed so i can turn the full backup back on?

Hi IndianLamp,
Thank you for posting in MSDN forum.
Based on your issue, you mean that you want t reduce the installation size of the version of VS Preview, am I right?
If yes, I know that when we download the version of the VS Preview from the Microsoft Official, it is default that the install package size. However, you can try to unselect some components during the installation, it will reduce the installation size of
preview edition.
If I misunderstanding your issue, please tell me more detail message about your issue.

REDUCE RMAN BACKUP TIME

Hi,
We have are 800GB database and we take daily backup through RMAN.
Backup policy is LEVEL 0 on week end and LEVEL1 AND LEVEL2 on other days.
When we take the backup our system utilization become high and which is effecting our 24X7 service.
How can I reduce the load on the database during backup.
Thanks in advance.

if you have a physical standby in place , or if you can create one, use that to backup. Using standby will completely off load your backup time & performance impact
other wise use RATE in channel
CONFIGURE CHANNEL DEVICE TYPE DISK MAXPIECESIZE <piecesize> K FORMAT '/backups/DBSID/DBSID.bkup.%U' RATE 2000000;

Reduce the execution time of catproc.sql

how can i reduce the time of execution of catproc.sql, I have increased the size of redo log files from 5m to 40m, but still performance hasn't improved much,
any suggestion

Is it still running? Almost half an hour now.
By the time we find a solution maybe it's already done :)
I don't think you could do much after it's already started. As long as it's not hung, it will finish sooner or later. Make sure there are no other applications runing on the server to compete CPU and diskio with oracle.
