Max datafiles size

hi there,
i want to know how much is the maximum size of a datafile?
I'm using oracle 8.1.7.4 on aix 4.3.3
db_block_size=8192
i have a datafile of 2GB and i need to expand it.
I was wondering if the maximum datafile size is 2 gb, so i do not need to increase this but create e new one
thanks

Without any reference at hand, the AIX (4.3.3, JFS) limits as I can recall
File size: 2GB
File size if large files enabled: near 64GB
File system size: 64GB with std fragment size.
Also observe the ulimit of the user who is using the file system.

Max Datafile Size Oracle 9i

Hi There,
We have multiple tablespaces in our database and the recently we got a message that the size of a particular tables has reached 97% and it needs to be increased.
Now currently the size of that tablespace is 29GB and before increasing the size of this tablespace we would like to know if there is a limitation for an Oracle data file size or are there any performance issues or implications that we may potentially face with a single data file of 30GB in size.
This is the biggest tablespace in our system other tablespaces are max 12 or 17 GB.
I am not a DBA just working in the support role as a developer. Could you please provide some insight on above query.
Many thanks in advance.
Regards
Sam

What is The Maximum Datafile Size Limit In Oracle Database 10gR2 [ID 804733.1]
Maximum number of Database blocks allowed in a single datafile in 10gR2 are as follows:
Small File Tablespace (Normal Tablespace) : 4194303 (2^22 -1)
Big File Tablespace (New in 10gR2) : 4294967295 (2^32 -1)
Max datafile size for SMALL FILE NORMAL TABLESPACE would be:

Max datafile size limit?

Hi,
Is there any maximum datafile size limit? May I resize my datafiles to, let's say, more than 4GB size?
(OS: RHEL4 32bit, DB: 10.2.0.3)
Thanks!

What would be the maximum datafile size that can support sql*loader

Hi,
I would like to load datafile from xls file which nearly 5 gb into oracle table by using sql*loader. Could you please tell me how much is max datafile size we can load by using sql*loader?
Thanks
VAMSHI

Hello,
The Size limit is mainly given by the OS. So you should care about what the OS could support as SQL*Loader files are unlimited on *64 Bit* but limited to *2GB* in *32 Bit* OS:
http://download.oracle.com/docs/cd/E11882_01/server.112/e10839/appg_db_lmts.htm#UNXAR382
Else, you should be able to load these data into the Table. So you must check that you have enough place inside the Tablespace and/or the Disk (if the Tablespace has to be extended).
Please find enclosed a link about SQL*Loader and scroll down to Limits / Defaults:
http://www.ordba.net/Tutorials/OracleUtilities~SQLLoader.htm
Hope this help.
Best regards,

Increase the Oracle datafile size or add another datafile

Someone please explain,
Is it better to increase the Oracle datafile size or add another datafile to increase the Oracle tablespace size?
Thanks in advance

The decision must also includes:
- the max size of a file in your OS and/or file system
- how you perform your backup and recovery (eg:do you need to change the file list)
- how many disks are available and how they are presented to the OS (raw, LVM, striped, ASM, etc.)
- how many IO channels are available and whether you can balance IO across them
Personal default is to grow a file to the largest size permitted by OS unless there is a compelling reason otherwise. That fits nicely with the concept of BIGFILE tablespaces (which have their own issues, especially in backup/recovery)

Recommend datafile size on Linux

Hi
Can anyone suggest in general what is the max recommended datafile size for Oracle database (8i,9i, 10g) on linux platforms.
datafiles are placed located on local server and i dont prefer keeping the autoextend on for Prod databases.
I heard that 4G is the best max size, after which we keep on adding datafiles as required.
Is that true?
Please suggest.
Thanks
Vk

I heard that 4G is the best max size, after which we keep on adding datafiles as required.
Is that true?well this is a myth, send it to mythbuster to get it bustered.
According to Oracle Document,
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14237/limits002.htm#sthref4183
Database file size Maximum
Operating system dependent.
Limited by maximum operating system file size; typically 2^22 or 4 million blocks
If your block size is 8k, that's 32G

Why datafile size not reduced ?

Hi,
I do not see the datafile size reduced after I drop tables in the tablespace of that datafile although the free table space reduced.
Question:
How to reduce the datafile without using alter datafile resize?
James.

I tried the exact proceedure you suggest and get exactly the same effect I mentioned previously. With this recent test all saves were with the save options Layers box checked. Here are the file size results. The only difference in size, as expected, is from the compatibility setting.

Both layers visible

Reducing datafile size

Hi guys,
I have one tablespace with 6 datafiles. each datafile has 5GB size, but only 2 GB is being used.
So I really need to reduce this datafile size to 3GB each.
unfortunatelly, when I try to reduce the datafile I get the following message :
ORA-03297: file contains used data beyond requested RESIZE value
How can I see wich schema and tables are being used in the end of the datafile ? So I´ll be able to move it and reduce the datafile size.
Thank you in advance,
Felipe

Below query can help you to show how much you cna reduce the datafile, without
move / rebuild command
column "File Name" format a45
column "Tablespace Name" format a25
select ff.file_id "File Id", ff.file_name "File Name",
ff.tablespace_name || ' (' || ff.block_size || ')' "Tablespace Name",
ceil (ff.blocks * ff.block_size / 1024 / 1024) "Current(MB)",
ceil (nvl(max_hwm.hwm,1) * ff.block_size / 1024 / 1024) "Smallest(MB)",
ceil ( ((ff.blocks * ff.block_size) - (nvl(max_hwm.hwm,1) * ff.block_size)) / 1024 / 1024) "Save(MB)"
from (select file_id, file_name, blocks,ts.tablespace_name tablespace_name, ts.block_size block_size
from dba_data_files f, dba_tablespaces ts
where f.tablespace_name = ts.tablespace_name) ff,
(select file_id, max(block_id + blocks - 1) hwm
from dba_extents
group by file_id) max_hwm
where ff.file_id = max_hwm.file_id(+)
order by ceil ( ((ff.blocks * ff.block_size) - (nvl(max_hwm.hwm,1) * ff.block_size)) / 1024 / 1024)
You can modify the query to show the objects located beyond 3GB.

Sophos AV max scanning size / timeout

Hi,
I haven't found any changeable settings for max. scanning size or scanning timeout on a S160 v7.1.3 with Sophos AV.
In the GUI under "Security Services-->Anti-Maleware" it shows "Object Scanning Limits: Max. Object Size: 32 MB".
I'm not able to change it. This parameter seems not to belong to the Sophos AV.
I can change it only after enableing Webroot or McAfee first.
The CLI has no commands for adjusting AV settings.
How can I control the max. scanning size or scanning timeout with Sophos-AV?
Has it fixed values for it?
Does anyone have an idea, how it works?
Kind regards,
Manfred

With administrator rights, the value should be editable. The object size is applied to all scanners which have been licensed and enabled on the appliance.

"max-pool-size" what is it good for?

SCreator simple CRUD use:
After a while I get:
" Error in allocating a connection. Cause: In-use connections equal max-pool-size and expired max-wait-time. Cannot allocate more connection"
Which is odd, because its just me using the server/database. It looks like every tiime I run a test, another conection is lost.
Do I have to restart the server? Is there a way to say "its only me, reuse a single connection"
why does "connection pooling" make life harder?
Can I turn it of?
cheers

<navigation-case>
<from-outcome>page13</from-outcome>

A good example:

with this mistake, the afterRenderedResponse() was never called, and the ResultRowSet was never closed.

Datafile size minor than 4 Gb: is this a bug?

Hi all! I have a tablespace made up by 1 datafile (size = 4 Gb). Oracle 9.2.0.4.0 (on Win2k server) seems incapable of managing this; in fact, I receive ora-04031: unable to allocate 8192 bytes of shared memory but the memory of Oracle is configured correctly. Resizing this tablespace and adding a new datafile so that every datafile is 2 Gb large, I don't receive the error any longer. what do you think about this?
Bye. Ste.

Hello everybody;
The Buffer Cache Advisory feature enables and disables statistics gathering for predicting behavior with different cache sizes. The information provided by these statistics can help you size the Database Buffer Cache optimally for a given workload. The Buffer Cache Advisory information is collected and displayed through the V$DB_CACHE_ADVICE view.
The Buffer Cache Advisory is enabled via the DB_CACHE_ADVICE initialization parameter. It is a dynamic parameter, and can be altered using ALTER SYSTEM. Three values (OFF, ON, READY) are available.
DB_CACHE_ADVICE Parameter Values
OFF: Advisory is turned off and the memory for the advisory is not allocated.
ON: Advisory is turned on and both cpu and memory overhead is incurred.
Attempting to set the parameter to the ON state when it is in the OFF state may lead to the following error: ORA-4031 Inability to allocate from the Shared Pool when the parameter is switched to ON. If the parameter is in a READY state it can be set to ON without error because the memory is already allocated.
READY: Advisory is turned off but the memory for the advisory remains allocated. Allocating the memory before the advisory is actually turned on will avoid the risk of ORA-4031. If the parameter is switched to this state from OFF, it is possible that an ORA-4031 will be raised.
Make sure too that you dont need to use RMAN program to make backup...baceuse the large pool is used to this too.
Regards to everybody

SharePoint - Error_1_Error occurred in deployment step 'Add Solution': Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was rea

Hi,
I am Shanmugavel, SharePoint developer,
I am facing the below SharePoint 2013 deployment issue while deploying using VS2012.
If i will deploy the same wsp or existing wsp
(last build) using direct powershell deployment, the solution adding properly, but the same timeout exception coming while activation the features. Please find the below error.
I tried the below activists:
1. Restarted my dev server, DB server.
2. tried the same solution id different server
3. tried existing wsp file (last build version)
4. Deactivated all the features, including project Active deployment configuration.... but still i am facing the same issue.
I hope this is not coding level issue, because still my code is not start running, before that some problem coming.
Please help me any one..... Last two days i am struck because of this...

What you need to understand is the installation of a WSP does not do much. It just makes sure that you relevant solution files are deployed to the SharePoint farm.
Next comes the point when you activate the features. It is when the code which you have written to "Activate" certain features for your custom solution.
Regarding the error you are getting, it typically means that you have more connections (default is I guess 100) open for a SQL database then you are allowed to.
If you have a custom database and you are opening a connection, make sure you close it as well.
Look at the similar discussion here:
The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool
size was reached[^]
I would suggest further to look at the
ULS logs[^] to get better insight.

Need info about max HDD size available for Satellite Pro M30-813

Hello,
The following question is mainly to be addressed to authorized Toshiba support personnel. What exactly is the limitation of a maximum size of an internal HDD that I could use with my Satellite Pro M30-813?
Recently, I have bought and installed seagate 160 GB SATA drive, onto which I have successfully installed WXP Pro and have been running it for quite a while with no problems. Recently, I have been copying large amount of data from an external hard drive to my new internal disk, and as the files were being copied as I noticed having about 50 GB free space left, I had experienced windows "delayed write failed" and a massive partition failure with no possibility to recover data. The system would no longer boot and the whole MBR was damaged. As the result, I have lost all data on my new disk.
Although, I realize that Toshiba is not responsible for additional hardware that I use with my laptop and that is not officially supported by Toshiba, I am certain that as an end user of a Toshiba product I have the right to know about a max HDD size limitation information for my notebook model. Therefore, I request Toshiba technical support representative to give me a straight official answer to my question.
Thank you in advance,
Andrejs
(You may also contact me privately at my e-mail address)

Hi Andrew
> The following question is mainly to be addressed to authorized Toshiba support personnel
I think you are in the wrong area if you are looking for an answer from an authorized Toshiba support.
This is a Toshiba user-to-user forum! You will meet here Toshiba notebook owner and enthusiasts who share knowledge and tries solve problems but nobody from Tosh :(
I could provide my experience with the M30 Satellite and the HDD upgrade possibilities.
In my knowledge the Sat M30 supports a 40GB, 60GB and 80GB HDD for sure.
In my opinion you could use the 100GB HDD but bigger HDDs will not run and functions correctly.
So switch to a lower HDD size and enjoy the notebook!
Ive goggled a little bit and found compatible HDD and the part numbers
HITACHI GBC000Z810 -> 80GB
HITACHI GBC00014810 -> 80GB
TOSHIBA HDD2188B -> 80GB
HITACHI G8C0000Z610 -> 60GB
HITACHI G8BC00013610 -> 60GB
TOSHIBA HDD2183 -> 60GB
TOSHIBA HDD2184 -> 60GB
I hope this could help you a little bit!

ASM on SAN datafile size best practice for performance?

Is their a 'Best Practice' for datafile size for performance?
In our current production, we have 25GB datafiles for all of our tablespaces in ASM on 10GR1, but was wondering what the difference would be if I used say 50GB datafiles? Is 25GB a kind of mid point so the data can be striped across multiple datafiles for better performance?

We will be using Redhat Linux AS 4 update u on 64-bit AMD Opterons. The complete database will be on ASM...not the binarys though. All of our datafiles we have currently in our production system are all 25GB files. We will be using RMAN-->Veritas Tape backup and RMAN-->disk backup. I just didn't know if anybody out there was using smallfile tablespaces using 50GB datafiles or not. I can see that one of our tablespaces will prob be close to 4TB.
