Maximum Data file size in 10g,11g

DB Versions:10g, 11g
OS & versions: Aix 6.1, Sun OS 5.9, Solaris 10
This is what Oracle 11g Documentation
http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/limits002.htm
says about the Maximum Data file size
Operating system dependent. Limited by maximum operating system file size;typically 2^22 or 4 MB blocksI don't understand what this 2^22 thing is.
In our AIX machine and ulimit command show
$ ulimit -a
time(seconds)        unlimited
file(blocks)         unlimited <-------------------------------------------
data(kbytes)         unlimited
stack(kbytes)        4194304
memory(kbytes)       unlimited
coredump(blocks)     unlimited
nofiles(descriptors) unlimited
threads(per process) unlimited
processes(per user) unlimitedSo, this means, In AIX that both the OS and Oracle can create a data file of any Size. Right?
What about 10g, 11g DBs running on Sun OS 5.9 and Solaris 10 ? Is there any Limit on the data file size?

How do i determine maximum number of blocks for an OS?df -g would give you the block size. OS blocksize is 512 bytes on AIX.
Lets say the db_block_size is 8k. What would the maximum file size for data file in Small File tablespace and Big File tablespace be?Smallfile (traditional) Tablespaces - A smallfile tablespace is a traditional Oracle tablespace, which can contain 1022 datafiles or tempfiles, each of which can contain up to approximately 4 million (222) blocks. - 32G
A bigfile tablespace contains only one datafile or tempfile, which can contain up to approximately 4 billion ( 232 ) blocks. The maximum size of the single datafile or tempfile is 128 terabytes (TB) for a tablespace with 32K blocks and 32TB for a tablespace with 8K blocks.

Sql loader maximum data file size..?

Hi - I wrote sql loader script runs through shell script which will import data into table from CSV file. CSV file size is around 700MB. I am using Oracle 10g with Sun Solaris 5 environment.
My question is, is there any maximum data file size. The following code from my shell script.
SQLLDR=
DB_USER=
DB_PASS=
DB_SID=
controlFile=
dataFile=
logFileName=
badFile=
${SQLLDR} userid=$DB_USER"/"$DB_PASS"@"$DB_SID \
          control=$controlFile \
          data=$dataFile \
          log=$logFileName \
          bad=$badFile \
          direct=true \
          silent=all \
          errors=5000Here is my control file code
LOAD DATA
APPEND

Hello Soma.
How many records exist in your 700 MB CSV file? How many do you expect to process in 10 minutes? You may want to consider performing a set of simple unit tests with 1) 1 record, 2) 1,000 records, 3) 100 MB filesize, etc. to #1 validate that your shell script and control file syntax function as expected (including the writing of log files, etc.), and #2 gauge how long the processing will take for the full file.
Hope this helps,
Luke

Impact of data file size on DB performance

Hi,
I have a general query regarding size of data files.
Considering DB performance, which of the below 2 options are better?
1. Bigger data file size but less number of files (ex. 2 files with size 8G each)
2. Smaller data file size but more number of files (ex. 8 files with size 2G each)
I am working on a DB where I have noticed where very high I/O.
I understand there might be many reasons for this.
However, I am checking for possibility to improve DB performance though optimizing data file sizes. (Including TEMP/UNDO table spaces)
Kindly share your experiences with determining optimal file size.
Please let me know in case you need any DB statistics.
Few details are as follows:
OS: Solaris 10
Oracle: 10gR2
DB Size: 80G (Approx)
Data Files: UserData - 6 (15G each), UNDO - 2 (8G each), TEMP - 2 (4G each)
Thanks,
Ullhas

(Including TEMP/UNDO table spaces)Remember this when tuning I/O: The fastest I/O is the one that never takes place! High I/O may very well be a symptom of unnecessary FTS or poor execution plans. Validate this first before tuning I/O and you will be much better off.

S1000 Data file size limit is reached in statement

I am new to Java and was given the task to trouble shoot a java application that was written a few years ago and no longer supported. The java application creates database files the user's directory: diwdb.properties, diwdb.data, diwdb.lproperties, diwdb.script. The purpose of the application is to open a zip file and insert the files into a table in the database.
The values that are populated in the diwdb.properties file are as follows:
#HSQL Database Engine
#Wed Jan 30 08:55:05 GMT 2013
hsqldb.script_format=0
runtime.gc_interval=0
sql.enforce_strict_size=false
hsqldb.cache_size_scale=8
readonly=false
hsqldb.nio_data_file=true
hsqldb.cache_scale=14
version=1.8.0
hsqldb.default_table_type=memory
hsqldb.cache_file_scale=1
hsqldb.log_size=200
modified=yes
hsqldb.cache_version=1.7.0
hsqldb.original_version=1.8.0
hsqldb.compatible_version=1.8.0
Once the databsae file gets to 2GB it brings up the error meessage 'S1000 Data file size limit is reached in statement (Insert into <tablename>......
From searching on the itnernet it appeared that the parameter hsqldb.cache_file_scale needed to be increased & 8 was a suggested value.
I have the distribution files (.jar & .jnlp) that are used to run the application. And I have a source directory that was found that contains java files. But I do not see any properties files to set any parameters. I was able to load both directories into NetBeans but really don't know if the files can be rebuilt for distribution as I'm not clear on what I'm doing and NetBeans shows errors in some of the directories.
I have also tried to add parameters to the startup url: http://uknt117.uk.infores.com/DIW/DIW.jnlp?hsqldb.large_data=true?hsqldb.cache_file_scale=8 but that does not affect the application.
I have been struggling with this for quite some time. Would greatly appreciate any assistance to help resolve this.
Thanks!

Thanks! But where would I run the sql statement. When anyone launches the application it creates the database files in their user directory. How would I connect to the database after that to execute the statement?
I see the create table statements in the files I have pulled into NetBeans in both the source folder and the distribution folder. Could I add the statement there before the table is created in the jar file in the distribution folder and then re-compile it for distribution? OR would I need to add it to the file in source directory and recompile those to create a new distribution?
Thanks!

Maximum recommended file size for public distribution?

I'm producing a project with multiple PDFs that will be circulated to a goup of seniors aged 70 and older. I anticipate that some may be using older computers.
Most of my PDFs are small, but one at 7.4 MB is at the smallest size I can output the document as it stands. I'm wondering if that size may be too large. If necessary, I can break it into two documents, or maybe even three.
Does anyone with experience producing PDFs for public distribution have a sense of a maximum recommended file size?
I note that at http://www.irs.gov/pub/irs-pdf/ the Internal Revenue Service hosts 2,012 PDFs, of which only 50 are 4 MB or larger.
Thanks!

First Open the PDF Use Optimizer to examine the PDF.
a Lot of times when I create PDF's I end up with a half-dozen copies of the same font and fontfaces. If you remove all the duplicates that will reduce the file size tremendously.
Another thing is to reduce the dpi of any Graphicseven for printing they don't need to be any larger than 200DPI.
and if they are going to be viewed on acomputer screen only no more than 150 DPI tops and if you can get by with 75DPI that will be even better.
Once you set up the optimized File save under a different name and see what size it turns out. Those to thing s can sometimes reduce file size by as much as 2/3's.

SAP Data File size considerably reduced after Unicode Conversion

Hello Experts
I have just performed a CUUC (Upgrade along with unicode conversion) from R/3 4.7 to ECC 6.0 EHP5. The data size that i earlier had was close to 463 GB (MSSQL MDF, LDF Files), after the data export to be converted to unicode the size was 45 GB (10% of actual data size, i feel this is normal after heterogeneous system copy), but after the import again the DATA file size is only 247 GB, is this normal ? or have i lost some data ? For ex, I tried checking tables like MSEG and the number of entries have reduced from 15,678,790 to 15,290,545.
Could you kindly let me know if there is a way to check from Basis perspective if i have not lost any data ? I have followed all the procedures as per SAP Standards.
Waiting for your quick reply.
Best Regards
Pritish

Hi Nicholas
Data is compressed during the new R3load procedure is understood, but why number of table entries have reduced is something which is still a question to me (in some cases increased as well) ? For example
                             Source          Target
STPO                  415,725          412,150
STKO                 126,710          126,141
PLAF                 74,671                   78,336
MDKP                 193,487          192,747
MDPB                 55,329                   63,557
Any suggestions or ideas ?

Maximum 3D File Size in AutoVue

Hi All,
Is there any limitation of maximum 3D file size which can be viewed on Autovue? Is it depending on the server hardware or the client hardware?
Best Regards
Akhmad H Gumas

The limitations are on both client and server hardware
It also has to do with the format been read, not all formats are equal and some require more memory to generate a display

Essbase cube data file size

Hi,
Why is it showing different numbers about my data file size in EAS>database>edit>properties>storage and a full database export.
Thanks,
KK

Tim, in all seriousness, I am not a stalker. Honestly. You just post about things that interest me/we share some of the same skills. Alternatively, Glenn stalks me, I stalk you, it's time for you to become a sociopath too and stalk someone else.
Okay, with that insanity out of the way, the other thing that could have a big impact on export size is if the OP did a level zero or input level export as opposed to a full export. In BSO databases in particular, that can lead to a very, very large set of .PAG (and to some extent .IND files) and a rather small export file size as the calculated values aren't gettting written out.
If the export is done through EAS I think the default is level zero.
Regards,
Cameron Lackpour
Edited by: CL on Sep 23, 2011 2:38 PM
Bugger, the OP wrote "full database export". Okay, never mind, I am a terrible stalker. I agree with everything Tim wrote re compression.
In an effort to add something useful, if you use the new-ish database archive feature in MaxL, you will essentially get .PAG files + .IND files combined into a single binary file. I used to be a big fan of full restructures, clears, and reloads to do defrags, but now go with the restructure command. Despite the fact that it's single threaded, in my limited testing (only done it at one client) it was faster as the export all, clear, reload. If you combine that with the archive mode you might have a better approach.

Is there a maximum project file size?

I am currently working on a project and the latest project file version I saved had about 922 KB - Premiere wouldn't want to open that again - it keeps crashing when I try to open it
Then I opened up a new project - imported just that sequence I was working on and suddenly it works again with a project file size of 238 KB
I have no idea what the reason for those crashes might be so I was wondering if there is such thing as a maximum project file size premiere can handle?

Welcome to our community
There really shouldn't be any load limitations other than those imposed by the Captivate files themselves. My guess is that you plan on using WebHelp, no? And if you are, the Captivate demos will be loaded as needed from the server. So the only lag you will see is the delay for what it takes for the server to serve up the demo itself.
Hopefully this answers your question. If not, post back and we will take another stab at it.
Cheers... Rick

Suggested data file size for Oracle 11

Hi all,
Creating a new system (SolMan 7.1) on AIX 6.1 running Oracle 11.
I have 4 logical volumes for data sized at 100gb each. During the installation I'm being asked to input the size for the data files. The default is "2000mb/2gb" is this acceptable for a system sized like mine, or should I double them to 4gb each? I know the max is 32gb per data file but that seems a bit large to me. Just wanted to know if there was a standard best practice for this, or a formula to use based on system sizing.
I was not able to find any quick suggestions in the Best Practices guide on this unfortunately...
Any help would be greatly appreciated.
Thanks!

Hi,
As you know archived log is create when online log is switch. Archived log size might be maximum equal to online redo log size.
Because archived log size is copied from online redo log file, if you want change archived redo log size, then you must change online redo log size.
But you must think, what is advantages and disadvantages of change of online redo log size, it depends direct task LGWR process.
You can change archived redo log name with change LOG_ARCHIVE_FORMAT parameter.
See : http://docs.oracle.com/cd/B19306_01/server.102/b14237/initparams103.htm

Data File Size

I wrote a java program that copies data from a Sql Server DB to Oracle 9i.
As the program ran, the oracle9i server ran out of disk space. I ran the 'clean' portion of my application that deletes all data from the tables. After I did this, there was still the same amout of free space on the hard drive.
I am not an oracle dba or expert by any means, I am a programmer but here is what I found, I'm not sure if its revelent.
On the oracle server I went to the following folder : oracle\ora92\database\DB40
I think this is the file where my data is stored. The file 'DB40DF' is 6 Gigs.
I have 2 other databases on the server that are exactly the same as my db40 database and their 'DF' file sizes are 130MB. These have no data in them yet. So from this I would assume that if I emptied all of my tables then the DB40DF should be around 130MB. But this is not the case, after I ran my delete code the file is still 6GIG.
Did I do my delete wrong? I assumed that my statment would commit and it seems to. When I do a select * from the tables there is no data. If there is no data in my table why is the file 6 gigs? I have included my delete java code incase I did something wrong on that side. If not, is there something I am suspose to do to get the DF file back to normal size? I have Toad 9.5 to administer the database.
Here is a portion of my delete java code:
stmt is a java.sql.Statement
for (String table : tables) {
sql = "DELETE FROM " + oracleSchema + table;
stmt.addBatch(sql);
int[] result = stmt.executeBatch();
if (stmt != null) {
stmt.close();
stmt = null;
When I print out the int array it shows how many rows were deleted from each table and the record cound seems ok. (ie table x clear 36007 rows deleted)
Thank you.

Oracle won't resize a datafile unless this is requested by the SQL statement ALTER DATABASE DATAFILE ... RESIZE... . Oracle won't release extents allocated to a table unless this is requested by the some ALTER TABLE statements. Extents will normally be reused by next INSERT statements. So the behavior you note is normal.
