Finding table fragmentation in Oracle 8.1.6.3.0
Hi All,
I just want to find table fragmentation for one table named LOG. I used below query to find this....
SQL> select table_name,round((blocks*8),2)||'kb' "size"
from dba_tables
where table_name = 'LOG' and owner='AMRWF1'; 2 3
TABLE_NAME size
LOG 6301408kb
SQL> select table_name,round((num_rows*avg_row_len/1024),2)||'kb' "size"
from dba_tables
where table_name = 'LOG' and owner='AMRWF1'; 2 3
TABLE_NAME size
LOG 1468846.2kbAnd tablespace infromation is below.
SQL> select bytes/1024/1024,TABLESPACE_NAME,EXTENTS,MAX_EXTENTS from dba_segments where owner='AMRWF1' and segment_name='LOG';
BYTES/1024/1024 TABLESPACE_NAME EXTENTS MAX_EXTENTS
6154.16406 WFMKTLEAST 12214 2147483645
SQL> sho parameter block
NAME TYPE VALUE
db_block_buffers integer 100000
db_block_checking boolean FALSE
db_block_checksum boolean FALSE
db_block_lru_latches integer 3
db_block_max_dirty_target integer 100000
db_block_size integer 8192
db_file_multiblock_read_count integer 8
hash_multiblock_io_count integer 0
sort_multiblock_read_count integer 2Please mention whether i am fallowing proper method to find table fragmentation and this table is severly fragmented or not???

How to find the count of tables going for fts(full table scan in oracle 10g
HI
how to find the count of tables going for fts(full table scan) in oracle 10g
regardsHi,
Why do you want to 'find' those tables?
Do you want to 'avoid FTS' on those tables?
You provide little information here. (Perhaps you just migrated from 9i and having problems with certain queries now?)
FTS is sometimes the fastest way to retrieve data, and sometimes an index scan is.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:9422487749968
There's no 'FTS view' available, if you want to know what happens on your DB you need, like Anand already said, to trace sessions that 'worry you'. -

How to find out if the Oracle is a 64 or 32-bit installation
Hi,
I have a customer who has a 64-bit enabled Solaris 8 machine with an Oracle installed on it.
Is there a simple and quick way to find if the installed Oracle is 64 or 32-bit installation. Something like a v$ table.
Thanks,
Tal ([email protected]).Hi,
if the database is running, start a sqlplus session. You will see in the banner something like '64Bit Production' (for 64-bit) or only 'Production' for 32-bit. Alternatively, especially if the database is not running, go to $ORACLE_HOME/bin and type 'file oracle'. The returning strings shows either 32-bit or 64-bit.
Best regards

Hi,

select * from dba_tables where table_name='OTP_PR_TRAVELLER' and owner='UAT_LIVE1'
Size:- 455 MB
Can anybody tell me - is my table fragmented , If yes, then how to defrag it ?Are you using automatic segment space management (ASSM)?
Almost everything is going to depend on how your table is set up and how it is used in practice. Optmal storage allocation is all about matching those two things.
What are the PCTFREE and PCTUSED settings on the table (if you aren't familiar with those settings, I'd strongly suggest reading the Concepts guide section on database blocks for background)? Can you describe the life cycle of a row? Do you ever do updates? Do those updates ever increase the size of a variable length column? Do you ever do deletes?
In general, the default settings are going to be pretty good for most tables in most applications. While a human being might be able to do a better job on some tables, there is a lot to be said for accepting the default, getting a very good but not quite optimal result, and focusing scarce human attention on things that are likely to have a much bigger return. Just because something can be made more optimal doesn't, by any stretch, mean that the cost of making the improvement is worth the effort.

Cannot disable table trigger in Oracle 9i
Hi,
I find out once a while I cannot disable table trigger in Oracle 9i 9.0.1.3.0. Whenever I disable it will hang for few minutes and then return an error saying 'time-out and the trigger cannot be disabled'. I have checked and all users are not using the table. I can only disable the trigger after I restart the Oracle instance or service. Anyone has this problem and how to solve it? Tks.plz post the error, what kind of trigger is it (ie login trigger)

Good points about the link:

it tells you that you have four options
it gives you one idea of how to check for possible "empty" space below the HWM
</ul>
Bad points about the link:
<ul>
it doesn't tell you anything about the nasty side-effects of the methods
it doesn't give you any information about the pros and cons of each method
the first three paragraphs are misleding

<blockquote>
When rows are not stored contiguously, or if rows are split onto more than one block, performance decreases because these rows require additional block accesses.
Note that table fragmentation is different from file fragmentation. When a lot of DML operations are applied on a table, the table will become fragmented because DML does not release free space from the table below the HWM.
HWM is an indicator of USED BLOCKS in the database. Blocks below the high water mark (used blocks) have at least once contained data. This data might have been deleted. Since Oracle knows that blocks beyond the high water mark don't have data, it only reads blocks up to the high water mark when doing a full table scan.
</blockquote>
para1: what is a "non-contiguous row" ? - the opening phrase needs explanation
para1: "if rows are split onto more than one block" - doesn't distinguish between migrated and chained rows
para2: <i>"DML does not release ..."</i> - of course it does, it's just a question of when. This remark should not be made without a proper explanation
para3: minor quibble - the article was written in 2007, and ASSM has been around a lot longer - there could be a significant number of blocks below the HWM which have not yet been formatted.
Conclusion: Article not suitable reference material.

Hi Basis Guru's
What is meant by Table Fragmentation?Plz help with steps..Hello,
Table Fragmentation
Table fragmentation is the inability of the system to lay out related data sequentially (contiguously), an inherent phenomenon in storage-backed file systems that allow in-place modification of their contents.
The correction to existing fragmentation is to compress tables and free space back into contiguous areas, a process called defragmentation.
Table fragmentation will result in longer query times when a full table scan is performed. Since data is not as evenly packed in the data blocks, many blocks may have to be read during a scan to satisfy the query. These blocks may be distributed on various extents. In this case, Oracle must issue recursive calls to locate the address of the next extent in the table to scan.
Recent studies have shown that table fragmentation has hardly any effect on the performance of the database system. This is mainly because full table scans are somewhat rare in an SAP system since data is accessed using an index.

Be fragmentation of Oracle resolved???
Edited by: user10821817 on 2009. 4. 20 오후 7:58OS Fragmentation is different thing and oracle fragmentation is different. OS fragmentation is for OS internals and its working to get better disk i/o and minimize user/service response; while in oracle if you are using locally managed tablespace (LMT) it provides you autometically coalesce.
Coalesce creates a big free extent by taking space from free extents and it is used in dictionary managed tablespaces (DMT); while if you use LMT it works autometically; we do'nt need to alter tablespace <tablespace name> coalesce;
So best is use LMT and move all objects from DMT to LMT i.e. alter table/index <object name> move tablespace <new LMT name>; or get object names from user_objects.

Importing table dump from oracle into sybase
I was wondering if anyone has ever imported a table dump from oracle into sybase. I just tried it and it didn't work. I used TOAD to create my table dump file but when i imprted it into sybase using bcp in i got the following error
cs_convert: cslib user api layer: common library error: The result is truncated because the conversion/operation resulted in overflow.
CSLIB Message: - L0/O0/S0/N36/1/0:If you are looking for a basic/standard way to exchange data between Oracle and Sybase, use the CSV format.
It is trivial to write a generic SQL*Plus script for Oracle to extract data from a table (or a SELECT) and spool this into a properly formatted CSV file.
It is also just as easy to use Sybase Bulk Copy utility to load that CSV file into Sybase.
There are also alternative methods. One would be to use Oracle's Heterogeneous Services. You can define a database link in Oracle that connects, via ODBC, to Sybase. And using this database link you can push (insert) data into Sybase.
