Applying “version 4″ Time Zone Files on an Oracle Database

Applying “version 4″ Time Zone Files on an Oracle Database

Applying “version 4″ Time Zone Files on an Oracle Database if your timezone file version is less than 4
Yesterday I was upgrading the database form 10.2.0.3 to 10.2.0.5 on RHEL 5,
In readme of the 10.2.0.5 patch i came across the timezoe files,
We need to upgarde the timezone files of the base database to 4, is minimum requirement.
I found my timezone files 3,

you can use following query to find the timezone of the database:
SQL> select * from v$timezone_file;
FILENAME        VERSION
------------ ----------
timezlrg.dat          3
 
If  your database versions are 9.2.0.8 & 10.2.0.4,your  timezone file version will be 4 by default,
upgrading to 11.1.0.6.0  or 11.2.0.1.0 we need timezone version 4,
If your database is 9.2.0.7, we need to upgarde it to 9.2.0.8
 or database versions are 10.2.0.1, 10.2.0.2, 10.2.0.3, then we need to upgarde the database to 10.2.0.4 then to upgrade the 11.2.0.1
Another & Best way is to apply the  “version 4″ Time Zone Files on an Oracle Database  
you can file the patches for your version from the metalink ID ID 413671.1

Go to end of the article,  Identify your version from the table, apply the patch,
your timezonefile version will be updated to 4, & you can proceed for the upgradation to 11g R1, 11gR2

IMPDP TABLE_EXISTS_ACTION = APPEND, REPLACE, [SKIP] and TRUNCATE

 

IMPDP  TABLE_EXISTS_ACTION PARAMETER EXPLAINED



 Data Pump IMPDP TABLE_EXISTS_ACTION = APPEND, REPLACE, [SKIP] and TRUNCATE
In conventional import utility (IMP) we have ignore =y option which will ignore the error when the object is already exist with the same name.

When it comes to the data pump there is one enhanced option of ignore=y which is called TABLE_EXISTS_ACTION. The values for this parameter give 4 different options to handle the existing table and data.

$ impdp help=y

    TABLE_EXISTS_ACTION
    Action to take if imported object already exists.
    Valid keywords are: APPEND, REPLACE, [SKIP] and TRUNCATE.

    SKIP: Default value for this parameter is SKIP. This parameter is exactly same as the IGNORE=Y option in conventional import utility.

    APPEND: This option appends the data from the data dump. The extra rows in the dump will be appended to the table and the existing data remains unchanged.

    TRUNCATE: This option truncate the exiting rows in the table and insert the rows from the dump

    REPLACE: This option drop the current table and create the table as it is in the dump file. Both SKIP and REPLACE options are not valid if you set the  CONTENT=DATA_ONLY for the impdp.

   
Method to Import only rows does not exist in the target table
See some examples here.

In this example lets use abc table in my schema (ATOORPU)

SQL> select * from abc;

I took the data pump dump export EXPDP of employee table.

   ------ TABLE_EXISTS_ACTION=SKIP  ------

In this example I want to use table_exists_action=skip, where I want to skip the table data in my import, if a similar table exists.

8 rows selected.

        ------ TABLE_EXISTS_ACTION=TRUNCATE     ------ 

    Now let’s try with table_exists_action=truncate option. In truncate option it will truncate the content of the existing table and insert the rows from the dump. Currently my abc table has 8 rows which we inserted last insert.

This option drop the current table in the database and the import recreate the new table as in the dumpfile.

Now if you check the last_ddl_time for the table it would be the same as the import time.

Svn client error svn: E160006: Invalid revision number '-1'

Topic : svn: E160006: Invalid revision number '-1' 

I have recently come across this error when I installed the svn client on my machine. I have the latest version of tortoise svn client on my local machine. After install I used to get this weird error when ever I used to do check out.

 


Unexpected HTTP status 500 'Server Error' on
 '/scm/svn/database/releases/!svn/vcc/default'
Additional errors:
svn: E160006: Invalid revision number '-1'


 I goggled a lot but nothing seems to work. Finally I figured out. The client and server versions are not same then I downloaded the same version of the tortoise client as of server. Then it seemed to work fine.


Conclusion :

Try to download the tortoise svn of same version as of server and it seems to work fine without any problem.
