Oracle GLOBALIZATION SUPPORT

GLOBALIZATION SUPPORT


Choosing a Character Set
---------------------------------
When computer systems process characters, they use numeric codes instead of the graphical representation of the character. For example, when the database stores the letter A, it actually stores a numeric code that is interpreted by software as that letter. Read on to know more about Globalization Support.

NLS Data Dictionary Views
----------------------------
Applications can check the session, instance, and database NLS parameters by
querying the following data dictionary views:

NLS_SESSION_PARAMETERS shows the NLS parameters and their values for the
session that is querying the view. It does not show information about the character
set.

NLS_INSTANCE_PARAMETERS shows the current NLS instance parameters that
have been explicitly set and the values of the NLS instance parameters.

NLS_DATABASE_PARAMETERS shows the values of the NLS parameters for the
database. The values are stored in the database.
--------------------------------------------------------
NLS Dynamic Performance Views

V$NLS_VALID_VALUES lists values for the following NLS parameters
NLS_LANGUAGE, NLS_SORT, NLS_TERRITORY, NLS_CHARACTERSET

V$NLS_PARAMETERS shows current values of the following NLS parameters:
NLS_CALENDAR, NLS_CHARACTERSET, NLS_CURRENCY, NLS_DATE_FORMAT,
NLS_DATE_LANGUAGE, NLS_ISO_CURRENCY, NLS_LANGUAGE, NLS_NUMERIC_
CHARACTERS, NLS_SORT, NLS_TERRITORY, NLS_NCHAR_CHARACTERSET, NLS_COMP, NLS_LENGTH_SEMANTICS, NLS_NCHAR_CONV_EXP, NLS_TIMESTAMP_FORMAT, NLS_TIMESTAMP_TZ_FORMAT, NLS_TIME_FORMAT, NLS_TIME_TZ_FORMAT

DBMS_WM.CompressWorkspace

DBMS_WM.Compress Workspace

 If   you version enabled the tables with  DBMS_WM.EnableVersioning ('TABLE_NAME', 'VIEW_WO_OVERWRITE')   API  THEN your  Oracle Workspace  database WILL  GET SLOW  WHEN SO MANY DATA COMES ; use DBMS_WM.CompressWorkspace API  TO MAKE IT FASTER; There is a scenario to check  whether your Workspace  is getting slow or Workspace database is to be Compressed or not ,execute this  workspace API
DBMS_WM.SetDiffVersions('LIVE',wksp2) . and  then  pick a version enabled table having highest record count   , issue command select count(*) from tablename_diff ; if it takes more than a minute to GET RESULT THEN YOU CAN MAKE SURE THAT YOU NEED TO COMPRESS YOUR WORKSPACE ;here u want to use the   statement  (1) , using statement (2) will not give better result because your table is version enabled  with DBMS_WM.EnableVersioning ('TABLE_NAME', 'VIEW_WO_OVERWRITE')  .

(1) exec DBMS_WM.CompressWorkspace('LIVE',compress_view_wo_overwrite => true);

(2) exec DBMS_WM.CompressWorkspace('LIVE')



VIEW_WO_OVERWRITE: The without overwrite (WO_OVERWRITE) option. A view named _HIST  is created to contain history information, and it will show all modifications to the same version of the table. A history of modifications to the version is maintained; that is, subsequent changes to a row in the same version do not overwrite earlier changes.

compress_view_wo_overwrite        A Boolean value (TRUE or FALSE).

TRUE causes history information between the affected savepoints to be deleted even if VIEW_WO_OVERWRITE was specified when versioning was enabled.

FALSE causes history information (between the affected savepoints) for a table not to be deleted if VIEW_WO_OVERWRITE was specified when versioning was enabled. (If VIEW_WO_OVERWRITE was not specified for a table, history information for the table is deleted regardless of the parameter value.) FALSE is assumed if the procedure format without this parameter is used.


Advantage
------------
1  Run-time performance for Workspace Manager operations is improved.
2  Less disk storage is used for Workspace Manager structures
