Storage clause for locally manged tablespace with unifom size extents

in oracle 9i PERSONAL EDITION
I HAVE CREATED A TABLESPACE TEST1 AS LOCALLY MANAGED WITH UNIFORM SIZE AS 256K.MY DB_BLOCK_SIZE IS 4K
I HAVE CREATED A TABLE XYX IN THE TEST1 TABLESPACE WITH THE STORAGE (INITIAL 52K NEXT 52K)
WHEN I QUERIED THE DBA_EXTENTS IT SHOWS THE INITAIL EXTENT AS 256 K
BUT WHEN I QUERIED THE DBA_SEGMENTS IT SHOWS THE INITAL_EXTENT AS 52K.
IS THEIR ANY SIGNIFICANCE OF SPECIFYING THE STORAGE CLAUSE IN LOCALLY MANAGED TABLESPACES.

take a example what is effect of set storage parameter in table whoes tablespace is locally manager and have uniform size
i have a tablespace whoes
[b]uniform size is 32k
but when i create a table then i set initial 128k
now when table is create it create 4 extent
of 32 each(32*4=128)
because tablespace uniform size is 32
if we give intial 256 then it create
8 extent(32*8=256)
like
create tablespace tt_check
datafile 'E:\ORACLE\SAFE_DATA\tt_check.dbf' size 10m
extent management local uniform size 32k;
create table tt_1
(no number)
tablespace tt_check
storage(initial 128k
next 128k);
1* select extent_id,segment_name,tablespace_name,bytes from dba_extents where segment_name='TT_1'
QL> /
EXTENT_ID SEGMENT_NAME TABLESPACE_NAME BYTES
0 TT_1 TT_CHECK 32768
1 TT_1 TT_CHECK 32768
2 TT_1 TT_CHECK 32768
3 TT_1 TT_CHECK 32768

Oracle Database Maximum size (Linux)

What is the maximum size possible
for an Oracle Database on Linux ?
Is it limited to 2GB ? (the max file size
under Linux)
Mysql allows 4GB max, but for each table.
In fact 2GB with Linux (due to Linux
Max file size = 2GB).
null

Log to sqlplus as system ...
1. Create a new tablespace & datafile.
CREATE TABLESPACE "TESTSPACE" DATAFILE '/db/u01/oradata/testdata.dbf' SIZE 1000M DEFAULT STORAGE ( INITIAL 100K NEXT 2K MINEXTENTS 2 MAXEXTENTS UNLIMITED PCTINCREASE 0 ) MINIMUM EXTENT 2K
2. Then add datafiles to the tablespace as needed...
ALTER TABLESPACE "TESTSPACE" ADD DATAFILE '/db/u01/oradata/testdata2.dbf' SIZE 1000M
This will add two 1000m datafiles...
You can alter and make the files sizes larger and smaller... You can also add more files...
Also when you create tables make sure you reference them to the testspace tablespace or they will default to the user tablespace which will not be able to accomodate large data without modification.
This is really just the tip of the iceberg...
I really recommend reading the server concepts manual.

How does OMW determine storage clauses?

Hi.
I'm probably being a bit thick here, but I can't work out how OMW works out the storage clauses for segments when migrating from SQL Server 7 to Oracle 8i.
I guessed that the default storage clause on the tablespace built during the migration would be used if nothing was specified within the "Override Default Storage Options" tab in the Oracle Model...
...BUT this does not seem to be true for all segments. In a migration that I did recently, a handful of segments had different NEXT extent sizes, and I can't work out why!
Anyone know about this?
Thanks for any help offered,
Dave.

"Other" refers to system files, downloads, documents..., everything that doesn't fit on the other categories. See > http://pondini.org/OSX/LionStorage.html

Exp/imp and storage clause

Is it possible to make an export of the database with the exp tool, but without the storage clause for tables and indexes?
My develop database is 2GB big, and when i make an export without data and import it in a clean production environment without data, the datafiles are also 2GB big.
The export parameter compress=Y/N doesn't matter.
Thanks

gert-jan, your post is unclear on by 2G big you mean the physical datafile size or the amount of space allocated within the tablespaces?
If you are allowing the import to create the tablespaces then they are going to have the same size as defined in test.
The compress=y/n option should make a difference in that the default compress=y would cause a larger value be written to the export file for the initial extent.
But an important question is how were the import database target tablespaces defined: dictionary or locally managed, uniform or auto-allocate.
If the tables were created with too large of allocations I would generate alter table move commands with storage clauses to resize the objects on the target. Then I would rebuild the indexes with storage clauses to do the same. You can change the initial extent size on a move/rebuild operation.
The version of Oracle is always important because Oracle has been known to change feature behavior and parameter default values with release changes.

How to calcalate the maximum size occupied by a table/row

Hi,
I am using the below query to find the maximum size occupied by a table per a row of data.
SQL> desc t2
Name Null? Type
NO NUMBER(1)
CH VARCHAR2(10)
SQL> select sum(data_length) from user_tab_columns where table_name='T2';
SUM(DATA_LENGTH)
32
Is this correct? Does oracle takes 22 bytes of space to store a column of Number(1) per a row as it shows below !?
1* select data_length from user_tab_columns where table_name='T2'
SQL> /
DATA_LENGTH
22
10
Please give your comments/suggestions
Thanks and Regards
Srikanth

If you are trying to do this for an existing table, you can get the actual number of bytes stored per column by:
SELECT VSIZE(column_name)
FROM tableSo, to get the largest row you could:
SELECT MAX(VSIZE(col1) + VSIZE(col2) ... + VSIZE(coln))
FROM tableIf you want to get the theoretical largest possible row size, then you can use something like:
SELECT SUM(DECODE(data_type,'NUMBER', ROUND((data_precision/2)+.1,0) +1,
                            'DATE',   7,
                            'LONG',   2147483648,
                            'BLOB',   4000,
                            'CLOB',   4000,
                            data_length)) max_length
FROM user_tab_columns
WHERE table_name = 'MY_TABLE'This works because:
For a number, Oracle stores two digits in each byte, and uses one byte for the mantissa. Note, if you are expecting negative numbers in your numeric columns then add one additional byte).
For a date, Oracle always requires 7 bytes.
A long is at most 2 GB in size.
Both Blobs and Clobs will be stored out-of-line when they are larger than about 4,000 bytes.
For other data types you specify bytes of storage when you define the column, and that is stored in data_length.
I'm not sure at this point what sort of sizes you would get for object type columns or nested tables.

Maximum size for JAR files on Nokia 3120 Classic

I am trying to download and install a java app for a Nokia 3120 classic, but when installing I get an error message telling me that the file is too big at 5.7mb.
I can't find the maximum size of .jar files for this phone anywhere.
Can anyone let me know what this is and whether there is any way to get the app to work.
Many thanks.
Alan Watson

YES THERE IS A WAY!! I only got this information from someone else. Thanks for that person.
Here are the steps:
1. Download the jar file you want to install, to your computer. Now open My computer, and on the upper left corner you shall see a menu, click the "Tools" button and then click "Folder options..." A little window will appear. Click the "View" tab. On this window you need to find an option "Hide extentions for known file types" below "Advanced settings". Then unmark or uncheck the box.
2. Now when you open my computer and go to the folder where you had downloaded the java file, the file name will read "(anyfilename).jar". HERE IS THE TRICK.
3. Rename the last part of your file. Instead of .jar change it to .jpg so that it reads "(anyfilename).jpg"
4. Now copy the renamed file and paste it in your mobile's C: or Memory Card drive.
5. Once you had pasted, rename the copied file back to what it was. i.e "(anyfilename).jar"
BASICALLY the phone limits a file with a ".jar" extention, you can fool it by renaming the extention to ".jpg" and then once the file is copied into the phones C:drive you can change the extention back to ".jar" by renaming it.
Share it. Hope it works for you! God bless...

Maximum size for Xserve RAID modules

What is the maximum storage size for an Xserve RAID module?
Years ago, an Xserve RAID was out of my price range. Now, I'm looking into getting one on eBay and playing around with it.
I have been making Mirrored RAIDS with Western Digital 3 TB My Books.
Can I put 3 TB drives in an Xserve RAID? It probably depends on the controller firmware or something.
Thanks for thinking about this.
Doc

Short answer is no, you can't.
The XServe RAID has IDE drives mounted in a carrier. The maximum size drive shipped by Apple, supported under 1.5.1 firmware on the controllers is 750GB, though finding these on the used market is farily difficult. Aside from that, any IDE drive can be put in the carriers. If your unit has 'blank' slots, these are indeed just blank slots - you will need to get carriers / drive modules if you want disks in the slot if that makes sense.
People on the Internet, myself included, have experimented down the route of using IDE to SATA bridges in the carriers with 2.5" SATA drives which are more freely available. This way you can utilise cheap drives in your drive modules, or even SSDs (which offer little benefit I have found). Some users have had success with 1TB 2.5" SATA drives in this method, but not with anything bigger it seems. Myself, I've had suceess with 500GB SATA and 256GB SSD with this hacky method.
Hope that helps.

Is there a maximum size limit for a single file?

I haven't been able to find a statement of the maximum size of a file. We're looking at storing several 5-10gb files in one file library.
Is it possible?
How badly would that impact performance?

maximum size of a file. All files are stored as Binary Large Objects (BLOBs), A BLOB max size is (4 gigabytes -1) * (the value of the CHUNK parameter of LOB storage). Oracle Content Services configures its LOBs to have a 32K chunk size
Note that there is a overhead by storing large files, you should compress your files if possible before storing them.
http://download-east.oracle.com/docs/cd/B25553_01/collab.1012/b25492/contentservices.htm#CACHJJGI
How badly would that impact performance?Compared to what? Oracle ASM gives you the ability to stripe your content over hundreds of physcal disks to improve the performence. http://www.oracle.com/technology/products/database/asm/index.html

DBIF_RSQL_INVALID_RSQL The maximum size of an SQL statement was exceeded

Dear,
I would appreciate a helping hand
I have a problem with a dump I could not find any note that I can help solve the problem.
A dump is appearing at various consultants which indicates the following.
>>> SELECT * FROM KNA1 "client specified
559 APPENDING TABLE IKNA1

ST22
What happened?
 Error in the ABAP Application Program
 The current ABAP program "/1BCDWB/DBKNA1" had to be terminated because it has
 come across a statement that unfortunately cannot be executed.
Error analysis
 An exception occurred that is explained in detail below.
 The exception, which is assigned to class 'CX_SY_OPEN_SQL_DB', was not caught
 and
 therefore caused a runtime error.
 The reason for the exception is:
 The SQL statement generated from the SAP Open SQL statement violates a
 restriction imposed by the underlying database system of the ABAP
 system.
 Possible error causes:
 o The maximum size of an SQL statement was exceeded.
 o The statement contains too many input variables.
 o The input data requires more space than is available.
 o ...
 You can generally find details in the system log (SM21) and in the
 developer trace of the relevant work process (ST11).
 In the case of an error, current restrictions are frequently displayed
 in the developer trace.

Hi,
Under certain conditions, an Open SQL statement with range tables can be reformulated into a FOR ALL ENTRIES statement:
 DESCRIBE TABLE range_tab LINES lines.
 IF lines EQ 0.
 [SELECT for blank range_tab]
 ELSE.
 SELECT .. FOR ALL ENTRIES IN range_tab ..
 WHERE .. f EQ range_tab-LOW ...
 ENDSELECT.
 ENDF.
Since FOR ALL ENTRIES statements are automatically converted in accordance with the database restrictions, this solution is always met by means of a choice if the following requirements are fulfilled:
1. The statement operates on transparent tables, on database views or on a projection view on a transparent table.
2. The requirement on the range table is not negated. Moreover, the range table only contains entries with range_tab-SIGN = 'I'
and only one value ever occurs in the field range_tab OPTION.
This value is then used as an operator with operand range_tab-LOW or range_tab-HIGH.In the above example, case 'EQ range_tab-LOW' was the typical case.
3. Duplicates are removed from the result by FOR ALL ENTRIES.This must not falsify the desired result, that is, the previous Open SQL statement can be written as SELECT DISTINCT.
For the reformulation, if the range table is empty it must be handled in a different way:with FOR ALL ENTRIES, all the records would be selected here while this applies for the original query only if the WHERE clause consisted of the 'f IN range_tab' condition.
FOR ALL ENTRIES should also be used if the Open SQL statement contains several range tables.Then (probably) the most extensive of the range tables which fill the second condition is chosen as a FOR ALL ENTRIES table.
OR
What you could do in your code is,
prior to querying;
since your select options parameter is ultimately an internal range table,
1. split the select-option values into a group of say 3000 based on your limit,
2. run your query against each chunck of 3000 parameters,
3. then put together the results of each chunk.
For further reading, you might want to have a look at the Note# 13607 as the first suggestion is what I read from the note.

Maximum size of a datafile

What is the maximum size we can give to a datafile?

user8850066 wrote:
What is the maximum size we can give to a datafile?Use this clause to determine whether the tablespace is a bigfile or smallfile tablespace. This clause overrides any default tablespace type setting for the database.
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.
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.

Maximum size of a virtual pool in SCVMM 2012R2

I have a Windows Server 2012 R2 running SCVMM
2012 R2 and an over-committed virtual storage pool. In Server Manager the capacity of this storage pool is 128TB which
translates to 140TiB which makes sense since the maximum allowed size by the storage array is 140TiB.
This same storage pool is shown under VMM with the size of 131,072GB (131TB)
which is 144TiB.
Where is this size coming from? Is this the maximum size allowed by the SCVMM? Or does SCVMM use
different measurement units?

Hi,
You can see the actual limit and also modify it using Siebel Tools. In your case, when you're talking about Contacts, the desired BC is "Contact Attachment".
-> Open Siebel Tools -> Business Component -> "Contact Attachment" -> Field -> "ContactFileSize" -> Check Property "Validation".
e.g. if Validation is "<= 5000000" it means that file can have a maximum size of 5 MB.
Adjust to your needs.

LocalStorage reach maximum size while there are only 800 Kb data in it.

I met an localStorage exception when I call API "localStorage.setItem()" 
we are developing a web site, we used host like aaaa.bb.com the case is : 
the local storage has about 560KB Data in localstorage and then I want to set an item into localStorage, the size of the new item is 301KB 
then the browser throw exception, the content of the exception is as follows: 
 
The way I used to test the size of localStorage is: JSON.stringify(localStorage).length 
 
"Persistent Storage maximum size reached" code:"1014" nsresult: "0x80530f6(NS_ERROR_DOM_QUOTA_REACHED)" 
I tested this function in other machines and in chrome, this exception will not occur, I want to know why this exception occurs on the machine, if there is any settings in firefox? or if there is any relationship with the cache size?

the root cause is found.
the reason is that aaa.domain.com and bbb.domain.com, the two sub domain will share the same space of localStorage because they are under the same top level domain domain.com.
aaa.domain.com reach maximum size when there is only 500KB data in localStorage because there is already 4.5MB data in localStorage of bbb.domain.com.

Maximum size of PSA

What is the maximum size of PSA ?
How many records could it accomodate at maximum ?

Hi,
In the DataSource maintenance, you can use the function "Technical attributes" to define the following values for DataSources in SAP and BI source systems.
- Data type for PSA (Persistent Staging Area) table
- Size category for PSA table
PSA Table
For PSA tables, you access the database storage parameter maintenance by choosing Goto ® Technical Attributes in DataSource maintenance. In dataflow 3.x, you access this setting Extras ® Maintain DB-Storage Parameters in the menu of the transfer rule maintenance.
You can also assign storage parameters for a PSA table already in the system. However, this has no effect on the existing table. If the system generates a new PSA version (a new PSA table) due to changes to the DataSource, this is created in the data area for the current storage parameters.

Maximum size of the image for uploading.

Dear All,
I wrote an image upload program for uploading Color images. I need to know the maximum size of the image to be uploaded.
I am using the class cl_gui_frontend_services=>gui_upload for uploading the image.
Regards,
Rahul R

you will be converting the image into 'TIFF' or 'BMP' to be uploaded through GUI_UPLOAD.
i think you can do it for large size also, and for any problem you will get the exceptions :
DP_OUT_OF_MEMORY : Not Enough Memory in Data Provider
DISK_FULL : Storage Medium full.
so try and see.
