View 3 Replies View RelatedServer Administration :: Change Database Character Set?
Jan 25, 2013Currently my oracle database character set is we8mswin1252 and it is only containing English data as well as spatial data (which is in English of course). I would like to change the Database character set so it could accept Arabic characters.
I have checked the below command on a test DB and it worked fine, but I want to know if it's recommended as a best practice when changing the character set to accept arabic and this won't corrupt my old entered Data ?
SHUTDOWN IMMEDIATE
STARTUP RESTRICT
ALTER DATABASE CHARACTER SET INTERNAL_USE AR8MSWIN1256
SHUTDOWN IMMEDIATE
STARTUP

Server Administration :: Change Space Allocation For Character Columns In Database
Oct 24, 2012I want to change space allocation for character columns in my database, So it will store them as 'CHAR' and not 'BYTE'.my character set is
SQL> SELECT VALUE FROM V$NLS_PARAMETERS WHERE PARAMETER='NLS_CHARACTERSET';
VALUE
----------------------------------------------------------------
AL32UTF8
SQL> alter system set NLS_LENGTH_SEMANTICS='CHAR' scope=both;
System altered.I bounced the instance just to make sure
System altered.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
Connected to an idle instance.
SQL>
SQL>
SQL> startup
ORACLE instance started.
[code].....
And then I want to see that when I create a table with some varchar2 column,The space for it will be allocated by chars, and not by bytes! However, when I run a check of create table, this is what I get:
SQL> drop table check_char;
Table dropped.
SQL> create table check_char (some_name varchar2(10));
Table created.
SQL> select a.char_used
2 from all_tab_columns a
3 where table_name='CHECK_CHAR'
4 and a.owner='SYS';
C
-
B
SQL>
What is the reason for space allocation to remain in BYTES and not CHAR, or what else I can check?

Change Data Capture For Java Processes And Not Databases?
Mar 11, 2013oracle 11.2.0.3 I have insert only tables that receive srecords from multiple processes at a rate of about 200/second. Each transaction can have up to 100 records. I have another set of processes that queries this table for the latest data. These processes run anywhere from once a minute to once an hour. Processes do not get all of the data. They get data based on a type field.
Both of these are from java middle tiers. The process that queries data (The subscriber) does so at the request of many remote servers (there will be vast numbers). I am not allowed to expose these downstream databases to the internet (they are not oracle DBs anyway) so I cannot use streams or golden gate
So basicallyInsert Process: multiple sessions that combined insert records up to 200/second. There will be between 1-100 records per commit.
Query Process: Downtream process makes a request to my middle tier. This middle tier runs a query to get the latest data and passes it back. This design is set and I cannot change it.
1. right now we capture the insert time of the record. However, at this rate of inserts some processes will commit faster than others. So I cant use a 'greater than my insert time' query.
2. streams/golden gate won't work. can't register these DBs.
3. don't want to serialize my inserts because since I am not sure I can keep up with the insert rate. I don't even know what the specs will be for the production hardware. I have to actually deliver this before its decided. So I am being conservative.
4. I really want to avoid updates on this table if possible. In part due to my limited ability to test.
5. due to the number of downstream processes it is possible that it will request data and for some reason fail to insert the data locally. So the downstream application will keep track of the latest data it received. This means that a subscriber may need to request the same data again.
Is there a way to set up change data capture with multiple subscribers to handle this? if my subscribers are just queries? All the queries come from the same servers(there will be several, but all the same thing). If so, when I performance test this are there any wait issues I should keep an eye on?

Server Administration :: How To Change Default XML Storage
Sep 21, 2012As per the bellow the default XML storage has been changed in 11gr2.
docs.oracle.com/cd/E11882_01/appdev.112/e10492/whatsnew.htm
Quote:
Oracle Database 11g Release 2 (11.2.0.2) New Features in Oracle XML DB
The following Oracle XML DB features are new in Oracle Database 11g Release 2 (11.2.0.2).
Default Storage Model for XMLType
The default XMLType storage model is used if you do not specify a storage model when you create an XMLType table or column. Prior to Oracle Database 11g Release 2 (11.2.0.2), unstructured (CLOB) storage was used by default. The default storage model is now binary XML storage.
We have a application which works fine on r1 but not on r2 due to this change, we are going to investigate resolving the issue on the application in the future, in the mean time we need to be able to use the CLOB storage.
Does any one know where we can change this functionality back to the pre 11gR2 change?

Server Administration :: Change SGA_TARGET And SGA_POOL_SIZE Parameters
Aug 31, 2010When I was going through the Enterprise Manager Grid Control, I found an error due to which I looked at the trace file and it said:
ORA-07445: exception encountered: core dump ACCESS_VIOLATION unable_to_trans_pc PC:0x7C81BD02 ADDR:0x49444E49 UNABLE_TO_READ]
I searched and found that it has something to do with the SGA parameters. I saw that the shared_pool_size and the sga_target paramters are set to 0...Also there are certain SQLs hanging at some point. I thought I should change the above mentioned parameters.
My question now is, can I use the Alter System statements from the SQL Plus to change these parameters, and do they change immediately or do I need to reboot the Oracle instance for those changes to take effect? I would like to do:
alter system set sga_target=400m;
alter system set shared_pool_size=200m;
would these work and take effect immediately?
Server Administration :: Trying To Change Tablespace And Datafile Properties On Fly
Aug 21, 2011This facility has one last 10g database and a very problematic tablespace and last datafile associated with it. The tablespace was set up with INITIAL_ EXTENT of 131,072 (128K) instead of the more 'normal' 4,194,304 (4M) and NEXT_EXTENT of 262,144 (256K) instead of 4,194,304 (4M).
More worryingly, the datafile has INCREMENT_BY set to 1 (8K) instead of 1,280 (10M) or 2,048 (16M).Has anyone ever updated sys.ts$.dflinit and sys.ts$. dflincr to modify the INITIAL_EXTENT and NEXT_EXTENT, and sys.file$.inc to modify the INCREMENT_BY?
