I am using oracle 10g with sga_max_size =4GB and db block size 16k. Now i am creating a tablespace with block size 32 kb , whats value i select for the parameter db_32k_cache_size.
Is there any standard way to calculate the value of this parameter.
1) When might one choose non-standard block sizes?
2) Why do we need to apply patch? Just to fix bugs?
SQL> select block_size from v$controlfile;
BLOCK_SIZE

16384
SQL> show parameter db_block_size;

db_block_size integer 8192
the 2 can have difference block size?

I was about to move some tables from one table space to another but it seems it is not possible to move partitioned tables between table spaces of different block sizes.
So far the only option I have is to export and then import back the data.
know if there is any way to move a partitioned table between table spaces of different block size?
I am using oracle 8.1.5 database and my temp01.dbf file size is increased upto 19.8 GB now i want reduce its size .

I read something about Baby Rac on wiki and there was information that only with Engerprise Edition RAC is an extra-charge option for Standard Edition RAC is included.

Quote:Oracle Corporation includes RAC with the Standard Edition of Oracle Database (aka Baby RAC), but makes it an extra-charge option for the Enterprise Edition
We do have corporate licencing model in our firm, so we can evaluate what version of Oracle we need to install (One, Standard or Enterprise) bu there is no matter what version we chosed, because our licensing model give us possibility to install the highest version. So usually we were choosing the Enterprise Editions.
But only limitation for us is an options. We can't have additional option like partitioning, RAC, Oracle Tuning Pack, etc... in order to have additional option we need approval from our financial management.
I have idea to change one of our installation from Enterprise Edition to Standard Edition in order to have RAC option for free. Like i said. If we want to have RAC in our Enterprise Edition we need additional approval of money expense - but this is not easy. But our licensing model give us possibility to install Standard Edition of Oracle instead or Enterprise Edition and have RAC option include without additional expenses.
We are working on migrating from 9.2.0.4 to 11.2 and we've set up a test machine so that we could test the install and the import (as well as test additional 11g features that we want to begin using).
So we created the database and created all of the tablespaces beforehand.
Our import command is
$ORACLE_HOME/bin/imp system/manager FULL=Y BUFFER=140000 FILE=/dbexport/Lhtech.exp VOLSIZE=2000M GRANTS=Y INDEXES=Y COMMIT=Y IGNORE=Y
However, when we run the import, we get the errors like so:

First of all, the block size in our "newly" created tablespaces is 8192...and these are obviously trying to recreate the tablespaces with a block size of 2048.
1) Why is it not ignoring these create tablespace commands when those tablespaces already exist?
2) how in the world do we get around the block size issue? We've tried nearly everything we could find, but we've still not had any luck.

View 5 Replies View RelatedI am working to understand the space allocation of table with the value we provided with the data type. For that I have created a table with varchar2 and length 50. Size of table created is of 65536 Bytes. This is when we don't have any insertion in the table. Later when we insert some rows, total size if the segment still remain same that is 65536 bytes.
Now again when I created table with varchar2 and length this time is 500 but still it is created with same size that is 65536. So can you just explain, on what values segment size depends on and how the length effect the size & space allocation.
db_block_size is 8192.
The only supported technique for converting an EE database to SE is export-inport, as documented in note 139642.1. Our client is reluctant to do this because of the downtime involved. It is however possible to open the EE database from an SE home, no problem.
The note says only Quote:When you just install the Standard Edition software, you will end up with Data Dictionary objects which are of no use (or perhaps even invalid) and possibly create problems when maintaining the database.

The problem is that the data of the table are 40GB while on the DB the table holds 400GB! How can I shrink and reuse that space except from drop/recreate and drop/import?
The table has no initial data, so that I can play with the INITIAL parameter. Data are inserted, updated and deleted all the time. I have run DBMS_ADVISOR which recommended to SHRINK table. I have performed the shrink :
alter table STG_XML shrink space COMPACT;
but I haven't gained any space.
As the undo segments are used in round robin fashion, Is it possible that with varying load (concurrent users, size and number of transactions), the size of Undo tablespace on a particular day is less than the Undo tablespace size few days back, by any chance?
As a basic understanding I know that Undo is preserved for read consistency and transaction, instance recovery So if there are lot of transaction on a database on 05 Feb and before that, but there aren't any transactions on 6,7,8,9, then on 10th Feb can we see the Undo tablespace size is less than that of 05 Feb?
In the following case when data belonging to table is not required for any queries, transactions, even then the undo size is not restored upon dropping the table.
As such for large operations and batch processes shall we keep undo tablespace with files as 'Autoextend' with 'Maxsize' as 'Unlimited'?

I have Oracle 11gR2 running on windows xp machine. Windows xp has total size of 150 GB and free space of 95 GB.
I checked the size of the database that I created. It showed the total size of the database as 2 GB and used space as 2 GB. If I want to increase the total size of the database to 50 GB, what should i do? Now which is the disk space size? Windows or Oracle?
I want to know what is the size of each granule for oracle 10g. I read it from the following link
[URL].........
There it is described that
Quote:
The memory for dynamic components in the SGA is allocated in the unit of granules. Granule size is determined by total SGA size. Generally speaking, on most platforms, if the total SGA size is equal to or less than 1 GB, then granule size is 4 MB. For SGAs larger than 1 GB, granule size is 16 MB. Some platform dependencies may arise. For example, on 32-bit Windows NT, the granule size is 8 MB for SGAs larger than 1 GB. Consult your operating system specific documentation for more details.
Now My query about full list of granule size for different platform like windows 64 bit, unix etc.

Ok, the above shows us:
- we have 55 blocks allocated to the table (still)
- 35 blocks are totally empty (above the HWM)
- 19 blocks contains data (the other block is used by the system)
- we have an average of about 2.8k free on each block used.
Therefore, our table
- consumes 19 blocks of storage in total.
- of which 19 blocks * 8k blocksize - 19 block * 2.8k free = 98k is used for our data.
not too sure this calculation is accurate for getting the size (data)of the table.

We had a database (DB A)that is having version 9.2.0.6.0.This DB is having multiple tables and volume of 6 million in individual tables.Another database is also 9.2.0.6.0 (DB B), this DB has Mviews pointing to DB A. Mviews are refreshed in every 15 mins, with fast refresh option in 90% cases and remaining having complete refresh.
Last weekend we have migrated DB 2 to version 10.2.0.4.0 - 64bi and on another server.After version upgrade and DB migration complete refresh was done once for all mviews.
Now DB A is generating huge amount of archive log and also it's UNDO space is getting fully consumed causing performance issue and DB hang.what has gone wrong and what we can do to improve response of DB A and also to reduce size of Archive log ?
The size of redolog member is 12m . Can I increase the size of that member dynamically, without adding a new member to that group and dropping the old one.
