Server 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?
Server Administration :: How To Know Character Set As Single Character Or Multi Character
Sep 26, 2013how do we know database character set is either single character set or multi character set?
While changing character-set from AL32UTF8 to WE8MSWIN1252 got "ORA-12712: new character set must be a superset of old character set".
Below are steps taken to resolve the issue -
ALTER DATABASE CHARACTER SET WE8MSWIN1252;
i got this error: ORA-12712: new character set must be a superset of old character set
below are the commands executed by me:
SQL> SHUTDOWN IMMEDIATE;
SQL> CONNECT SYS/password AS SYSDBA;
SQL> STARTUP MOUNT;
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL> ALTER DATABASE OPEN;
SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE WE8MSWIN1252;
SQL> SHUTDOWN;
SQL> STARTUP;
SQL> QUIT;
And its working...
I have not done it in proper order. Neither have done ccsscan. Still, no user reported any issues. Do my changes truncated the data?

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?

What all other methods should I check? What do I check in PL/SQL if varchar and char type declarations exist in code? How do i check implication of database character set change to AL32UTF8 for byte bases SQL function.
