Possible to create table to consist of one block only (or is 8 default)

Fri, 03 Feb 2012 09:21:45 GMT

Possible to create table to consist of one block only (or is 8 default)

While I was busy doing block dumps of a table,

to check somehting.

noticed that , that Oracle (in my situation anyway, Oracle 11g, block_size 8k) created the table with a minium of 8 blocks.

Or so it states in dba_segments and dba_extents. (I did more tests and created various more tables and yes, always 8 blocks).

However when looking at dba_tables it says one block an no empty blocks. (true, this info can only be obtained after running stats, that does not make it less valid, though ?).

I would have expected to see 7 empty blocks. Instead is says 0.

Really puzzled here. Are we talking different blocks here ?

If it is 8 blocks. (I reason that an extent by default has 8 blocks due tablespace is locally managed, Oracle takes 8 blocks in one go, right)

Then the I presume the block_id is relating the the first block of the extent. Am I right. Still Why ? Why not block_id_range if it is 8.

This suddenly spawns a lot a questions in my head:

Q: Why the difference between blocks in dba_tables and...

DataPump Multiple file in multiple storate volume

DataPump Multiple file in multiple storate volume

Hi All,

I have storage volume of 100GB each for exp or data pump backup. My export file will be having more then 150 GBs. I am using exp and generating 40GB export files in separate volume /vol1 and /vol2 of 100 GB each. Now I want to use data pump instead of exp.

My Directory name is 'EODSOD_BACKUP' with '/vol1' path. I can create separate files in '/vol1' and its sub directories ( like file=/vol1/dmp01.dmp, /vol1/bkp/dmp02.dmp,  /vol1/bkp1/dmp03.dmp etc... ). How can I create files like /vol1/dmp01.dmp, /vol2/dmp02.dmp ?

Thanks in advance,

2) For another tables with query and parallel > 1 working fine
3) some tables are giving below error:

deleting large amount of data without shutdown db

Thu, 02 Feb 2012 09:31:09 GMT

deleting large amount of data without shutdown db

hi guys,

I need to remove large chunk of data from a table  keeping only data that i wanted.

I do not want to use delete knowning that it will generate tons of redo.

My intention was to do create a new table keeping only data that i want, drop the existing, and rename this new table.

-----------------------------------

But this will incurred downtime as I have the sync whatever data not brought over to the new table before i drop the existing table

t1) create new table as select range

t2) shutdown

t3) manual sync data (from T1 to T2) from old table to new table base on ID , or date.

t4) drop old table

t5) rename newtable 

t6) startup

-------------------------------------

I do not want to incurred the downtime or reduce it further at T2, so i am thinking of online redefinition 

but with online redefinition, i cannot choose the data that i want only. whole table will be sync.

-------------------------------------

Any other way out ?

Regards,

Noob

Securing the listener for 9i databases (and lower)

Wed, 01 Feb 2012 16:46:04 GMT

Securing the listener for 9i databases (and lower)

Hi,

By default, the security option within the listener status is OFF for 9i databases and lower. It means that the listener properties could be remotely modified. 

If the listener runs on a database server A, from a security standpoint, how can the listener interface be accessed from a remote server B? I mean not using ssh connection from A to B when using a Linux/Unix environment. How can this be done from a Windows server?

In such a way how can de listener be protected except by assigning explicitly a password (it has advantages and inconveniences).

Thanks by advance for sharing your security experiences.

Kind Regards.

SQL question - DECODE and GROUP BY - a trivial question I think

Hi all,

I have the following SQL which is working as expected.


select trunc(last_analyzed) "LAST_ANALYZED",

       count(*), decode(db_unique_name,null,name,db_unique_name) DBNAME, to_char(sysdate,'DD-MON-YYYY HH24:MI:SS') "RUNTIME"

from dba_tables, v$database

where owner='SYS' and last_analyzed >= sysdate-20

group by trunc(last_analyzed), decode(db_unique_name,null,name,db_unique_name)

order by trunc(last_analyzed)

;

I just want to know whether it is possible to shorten the group by where I don't have to specify the whole decode string?

I tried the one below which seems to work. Just not sure whether it is the right thing to do. What if the decode is not as simple as this one and it has several checks unlike this example here where it only checks for null?
