Alter database set TIME_ZONE error

I am following along in the first Sybex OCA book with Oracle 9i Personal Edition using version 9.2.0...(I believe 9.2.0.0.1?)
I am using the seed database that contains hr and various others...I got to the following command, but under the hr login, it says I do not have permission. So I tried logging in as system and it claims ORA-02231: missing or invalid option to ALTER DATABASE. The same occurs if I login under sys AS sysdba (or as sysoper) or if I login under system AS sysdba.
I tried the command (which I no longer remember) to export the init.oca settings (it created INITorcl.OCA or initORCL.oca) as one message indicated it might be the compatibility setting. However that was set to 9.2.0 and the message said it needed to be 9.1 or higher.
What am I doing wrong?
It is on P. 142, Chapter 3 (single-Row Fucntions) and the command is simple enough...
ALTER DATABASE SET TIME_ZONE='-06:00';
(and it should reply database altered)
I have also tried ALTER DATABASE SET TIME_ZONE='US/Central'; and many, many other variances. Ideally, after that succeds one should do a
SHUTDOWN
STARTUP
and then be able to SELECT DBTIMEZONE FROM dual; to get a dbtime of -06:00, but since it thinks my assignment is invalid, I cannot find a way to get it to accept it. Plz help. I have been searching extensively and trying numerous ideas. While I know it is of little importance now, I want to understand every aspect I can.
This is the book by Chip Dawes and Biju Thomas (OCA/OCP: Introduction to Oracle9i SQL Study Guide)
Thanks,
Ross

You can only change the database timezone if you have no TIMESTAMP WITH LOCAL TIMEZONE columns in the database.
TSLTZ columns are stored normalized to the database timezone, that means that after changing the database timezone the interpretation of the data would be wrong.
ORDERS.ORDER_DATE in the demo schema OE is an TSLTZ column
If you remove this column you can change the database timezone.

ALTER DATABASE SET COMPATIBILTY_LEVEL executes irrespective of IF EXIST condition

Hi,
Problem:
I want to set compatibility_level only when it is greater than 110.
Solution:
Select the compatibility level and if it is greater than 110, I alter database set compatibility level=110
ISSUE
Irrespective of IF Exist statement the alter database statement is executed all the time.
Here is the sql statement
IF EXISTS (
SELECT * FROM sys.databases where compatibility_level >110 AND name='mydatabase'
BEGIN
ALTER DATABASE mydatabase SET COMPATIBILITY_LEVEL = 110
END
What is that I am missing here ??
please support.

Hi Gokula,
Based on my tested, the syntax of your query is correct which you can see on the screenshots below.
When COMPATIBILITY_LEVEL is 120.
When COMPATIBILITY_LEVEL is 110.
So in your scenario, please check the current COMPATIBILITY_LEVEL.

Any help ?

Hi,
Duplicate is not supported using different version of database, so I recommend you don't use duplicate.
Because RMAN "duplicate" attempts to automatically rename (rename required recover) and open the database you may not use RMAN duplicate for this case, only RMAN restore.
Perform this work using normal restore database.
See this example.

Alter database begin backup; missing keyword error

Hi all,
I am trying to put my database in backup mode using the command "alter database begin backup", but it is giving error shown below:

pls...
Thanks in advance.
SHAILESH

Hello,
All the former posts are right, alter database begin backup; doesn't exists in 9.2 althought
you already have in this release the alter database end backup;.
So as to put all the tablespaces in backup mode in one command I suggest you to create a
stored procedure as follows:
CREATE OR REPLACE PROCEDURE begin_backup IS
TYPE RefCurTyp IS REF CURSOR;
cv RefCurTyp;
sql_cv VARCHAR2(400);
tbs VARCHAR2(128);
sql_stmt VARCHAR2(200);
BEGIN
-- Mise en BEGIN BACKUP des TABLESPACES
sql_cv := 'SELECT distinct (A.name) FROM sys.v_$tablespace A, sys.v_$datafile B, sys.v_$backup C where A.TS# = B.TS# and B.FILE# = C.FILE# and C.STATUS = ''NOT ACTIVE''';
OPEN cv FOR sql_cv;
LOOP
FETCH cv INTO tbs;
EXIT WHEN cv%NOTFOUND;
sql_stmt := 'ALTER TABLESPACE '||tbs||' BEGIN BACKUP';
EXECUTE IMMEDIATE sql_stmt;
END LOOP;
CLOSE cv;
END;
Then, I just have to call the Procedure like that:
execute <schema>.begin_backup; and all the tablespaces are in backup mode.
This procedure must be created on a User/Schema with the following privileges:
alter tablespace
select on sys.v_$tablespace
select on sys.v_$datafile
select on sys.v_$backupHope it can help.
Best regards,
Jean-Valentin

Errors in alert log and listener log and "alter database mount exclusive"

Hello!
I need a help.
Database 11R2 works under MS Windows Server.

Next - alter database open.
After this, it seams that program, which should put data into database, can not work with it, because I see errors in alert log: ora-12537, 12560, 12535, 12570, 12547.

ALTER DATABASE CHARACTER SET UTF8;
But the error being thrown is "New charset needs to be a superset of the old charset.
Can i migrate from ANSCI TO UTF8 on Oracle 8i?

What do you get when you query your database using the following SQL statement?

"Alter system set command" in a RAC database!!

Hi, all.
The database is (10.2.0.2.0) 2- node RAC database on 32-bit windows 2003
EE SP1.
I issued the following command on Node 1 database.
--> Alter system set db_block_buffers= xxx sid='rac1';
I was able to see "PE enqueue" in top 5 wait event section from an AWR report.
In addition, I was able to find "PZ99","PZ98" process dump file in BDUMP.
Soon later, I could find CKPT and DBWR hung.
Is there anyone who experienced this issue?
Thanks and Regards.

Hi:
It seems when you are starting RMAN it's executing some commands (one 'ALTER SESSION...'. It's seems to be a batch which has a bad value for SORT_AREA_SIZE. Find it and modify to a proper value as message shows. If you can't find start RMAN by calling directly the executable ($ORACLE_HOME/bin/rman or %ORACLE_HOME%/bin/rman.exe).

How to alter database character set from AL32UTF8 to EE8MSWIN1250

Hi folks,
I'm using an Oracle 10g, XE database, which has a database character set set to AL32UTF8, what causes that some characters like "č ť ř ..." are not displayed.
To fix this issue, I would like to change it to EE8MSWIN1250 character set as it's set on server.
Unfortunatelly below steps don;t work for me:
connect sys as sysdba;
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE NATIONAL CHARACTER SET EE8MSWIN1250;
ALTER DATABASE CHARACTER SET EE8MSWIN1250;
SHUTDOWN IMMEDIATE; -- or SHUTDOWN NORMAL;
STARTUP;Value in regedit: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_XE is set to CZECH_CZECH REPUBLIC.EE8MSWIN1250
I'm struggling with this issue for hours and unfortunatelly can't make it work. Any advise is more than welcome.
Thanks,
Tomas
I tried to use hints listed here , but always getting some ORA messages.

Hi Sergiusz,
Thank you for your reply. You're right, I've probably didn't provide a full details about my issue, but at least now I know, that database encoding(characterset) is correct.
Here is my issue:
Within my APEX application I would like to use a JasperReportsIntegration, so to be able to create and run iReports straight from APEX application. Installation, and implementation of JasperReports works fine, I had no issue with it.
As a second step I've created a simple report using iReport tool, when if preview function is used, all static characters (from report labels) are displayed correctly. Database items are displayed incorectly - some Czech characters are not displayed. Language within report is set to cs_CS, but I've tried also other options. No sucess.
When I run that report from APEX application (from server) then the same issue - data from database are returned without some czech characters.
Kind regards,
Tomas

Startup command starts database but alter database open read only gives error

Hi,
I'm having some strange behavior. I've 10.2.0.3 database on windows 2003.
The startup command starts database without any issues.
But if I try following it gives error.
startup mount (successful no errors)
alter database open read only; gives error that file Mnnnnnn is missing.
Why this is happening and how to fix it?
Thanks.

You really need to show us exactly what Oracle is telling you, using copy and paste, so we can have some clue. You can hide details like instance and host names if they show up.
I'm wondering if you had some messed up offline datafile in a tablespace, where Oracle handles it with startup, but gets upset when you try to open read-only. It's some bizarro sequence of events like: add a datafile to a tablespace, decide that was a mistake, alter it offline, then remove it from the OS without telling Oracle any more about it. I've come back from vacation to find scenarios like this, it winds up being a time-bomb trying to recreate a standby later. Or something like that, I could be unremembering some details.

Alter database statement in anonymous pl/sql block

Is it possible to include an alter database statement in an anonymous pl/sql block?
When I execute this code to query user_tables for all table names, disable their constraints and drop the table, I got the following error:
***MY CODE
-- DECLARE VARIABLE(S)
DECLARE
     v_TABLE_NAME TABLE_NAME.USER_TABLE%TYPE;
-- DECLARE AND DEFINE CURSOR
CURSOR c_GETTABLES is
     SELECT TABLE_NAME from USER_TABLES;
BEGIN
OPEN c_GETTABLES;
LOOP
FETCH c_GETTABLES into v_TABLE_NAME;
EXIT when c_GETTABLES%notfound;
ALTER TABLE v_TABLE_NAME DISABLE PRIMARY KEY CASCADE;
DROP TABLE v_TABLE_NAME;
END LOOP;
CLOSE c_GETTABLES;
END;
***RESPONSE FROM SERVER
ALTER TABLE v_TABLE_NAME DISABLE PRIMARY KEY CASCADE;

When you want to perform ddl statements in a (anonymous) PL/SQL block, you have to use dynamic SQL because ddl is not possible in pl/sql.
Dynamic sql means that you sort of execute ddl statements in a sql manner. To use dynamic sql, two options exist:
- dbms_sql package : for oracle before 8i. To use this package is not always easy. Read about it carefully first before using.
- Native Dynamic SQL : implemented in 8i and very easy to use. An example would be :
declare
lv_statement varchar2(32676);
begin
lv_statement := 'ALTER TABLE MY_TABLE DISABLE CONSTRAINT MY_TABLE_CK1';
execute immediate lv_statement;
lv_statement := 'ALTER TABLE MY_TABLE ENABLE CONSTRAINT MY_TABLE_CK1';
execute immediate lv_statement;
end;
Good luck.
