Oracle Database : Space used in the flash recovery area

Here is a small script adopted from the book "RMAN Recipes for Oracle 11g" by Darl Kuhn, Sam R. Alapati and Arup Nanda. This script when run in from SQL Plus, will display the amount of used space in the current database flash recovery area.

Totals:                123595.09             391.11

The concept is very simple. Oracle provides two views for retrieving information about the flash recovery area. One is the v$recovery_file_dest that contains information about the flash recovery area associated with the current database. A select * on this view will give us an output like the following :

SQL> select * from v$recovery_file_dest;

NAME
--------------------------------------------------------------------------------
SPACE_LIMIT SPACE_USED SPACE_RECLAIMABLE NUMBER_OF_FILES
----------- ---------- ----------------- ---------------
/u01/app/oracle/flash_recovery_area
 2147483648 1668797952          93845504              16

This view provides the total number of used and reclaimable bytes from the flash recovery area. The next view named v$flash_recovery_area_usage, provided percentage information about each type of file that can be stored in the flash recovery area. Doing a select * on this view gives up the following results.

SQL> set linesize 100;
SQL> select * from v$flash_recovery_area_usage

FILE_TYPE            PERCENT_SPACE_USED PERCENT_SPACE_RECLAIMABLE NUMBER_OF_FILES
-------------------- ------------------ ------------------------- ---------------
CONTROL FILE                        ,45                         0               1
REDO LOG                           7,32                         0               3
ARCHIVED LOG                      20,08                      4,37              10
BACKUP PIECE                      49,81                         0               2
IMAGE COPY                            0                         0               0
FLASHBACK LOG                         0                         0               0
FOREIGN ARCHIVED LOG                  0                         0               0

... so the next logical thing in order to get something meaningful out of these is to join them and this is what the initial script does. Since the v$recovery_file_dest view has only one column, all columns of the v$flash_recovery_area_usage view refer this hence the no need for a where clause in the script's sql.

Oracle 11g How to determine the database character set

This is only a quick note for something I keep forgetting. So to determine the oracle database character set use the following simple SQL statement.

   select *
      from v$nls_parameters
      where parameter='NLS_CHARACTERSET'

Oracle 10g Killing open sesions

We have a client program that leaves lots of open sessions. These sessions take up server resources and we wanted to find a way to locate and kill them.

Thanks to Natasa Oikonomidou from Softworks who provided the code, I ended up with the following solution:

Create a the following procedure on the sys schema.

create or replace
PROCEDURE inactive_session_killer
IS
  now DATE;
BEGIN
  now := sysdate;
  FOR rec IN
    (SELECT sid,
       serial#,
       username,
       schemaname,
       osuser,
       terminal,
       machine,
       PROGRAM,
       status,
       type,
       saddr,
       logon_time,
       now - last_call_et / 86400 last_activity
     FROM v$session
     WHERE username = 'XXXXX'   -- user name of open session "leaver"
           AND type = 'USER')
  LOOP

    IF rec.last_activity <( now  - 8 / 24) THEN
      -- inactive for more than 8 hours
      -- you can keep a log table here: inserrt into ...
      EXECUTE IMMEDIATE 'alter system kill session ''' ||  
                                        rec.sid || ',' || 
                                        rec.serial#    || 
                                        ''' immediate';

    END IF;

  END LOOP;
END;

Using SQLPlus or SQL Developer execute the following

 
VARIABLE jobno number;
BEGIN
   DBMS_JOB.SUBMIT(:jobno, 'inactive_session_killer;', SYSDATE, 'SYSDATE + 1/24');    -- runs every hour
   commit;
END;

... and that does it.

Oracle 10g SQL Mass rebuild and move the indexes of a specified user

Here is a function that rebuilds or coalesces the indexes of a specified user.If asked to rebuild the indexes then you can supply a table space to move the rebuild indexes into.

The function takes three parameters :

• user_name : The name of the user whose indexes are to be updated
• rebuild_type : Ether C or R to indicate Coalesce or Rebuild operation
• tablespace_name : Optional parameter to indicate where to move the indexes in case of rebuild

The function should be executed by a user with DBA privileges and this code is as follows

create or replace PROCEDURE rebuild_user_indexes( user_name IN VARCHAR2, 
                                rebuild_type IN VARCHAR2, 
                                tablespace_name IN VARCHAR2 DEFAULT NULL) 
AS
  full_index_name VARCHAR2(100);
  index_command VARCHAR2(10);
  sql_str VARCHAR2(100);
  
  total_indexes Integer;
  updated_indexes Integer;
  
  CURSOR get_index_cursor IS
    SELECT index_name, index_type 
    FROM dba_indexes
    WHERE owner = user_name AND
          index_type in ( 
              'BITMAP', 
              'NORMAL', 
              'FUNCTION-BASED NORMAL', 
              'FUNCTION-BASED DOMAIN');
      
BEGIN
  /* check initial parameters */
  IF rebuild_type <> 'R' AND rebuild_type <> 'C' THEN
    raise_application_error( -20999, 'rebuild type should be "C" or "R"');
  ELSIF rebuild_type = 'R' THEN
    index_command := ' Rebuild';
    /* if a rebuild tablespace is also defined */
    IF tablespace_name <> '' THEN
      index_command := index_command || ' tablespace ' || tablespace_name;
    END IF;
  ELSE
    index_command := ' Coalesce';
  END IF;
  
  total_indexes := 0;
  updated_indexes := 0;
  /* get all indexes that belong to the specified user */
  FOR r IN get_index_cursor LOOP
    total_indexes := total_indexes + 1; 
    dbms_output.put_line( total_indexes || ' ' || 
                          r.index_name || ' ' || 
                          r.index_type);

    /* Coalescing works only on normal B-Tree indexes, 
     * while rebuilding works with everything.
     */    
    IF (rebuild_type = 'R') OR 
       (rebuild_type = 'C' AND instr( r.index_type, 'NORMAL') > 0) THEN
      
      full_index_name := user_name || '.' || r.index_name;
      sql_str := 'alter index ' || full_index_name || index_command;
      
      BEGIN
        /* attempt to modify the index */
        EXECUTE IMMEDIATE sql_str;
        updated_indexes := updated_indexes + 1;
      EXCEPTION
        WHEN OTHERS THEN
          /* display the command and the error that occured during index 
           * update 
           */
          dbms_output.put_line( sql_str);
          dbms_output.put_line( sqlcode || ' ' || sqlerrm);
          /* continue working */
          NULL;
      END;
    END IF;
  END LOOP;
    
  /* report results */
  dbms_output.put_line( 'Indexes examined :' || total_indexes);
  dbms_output.put_line( 'Indexes Updated  :' || updated_indexes);
END rebuild_user_indexes; 

Thanks to SQLDeveloper running the function can is as easy as copying and pasting the following in SQLPlus.

DECLARE
  USER_NAME VARCHAR2(200);
  REBUILD_TYPE VARCHAR2(200);
  TABLESPACE_NAME VARCHAR2(200);
BEGIN
  USER_NAME := NULL;       -- add your user here, for example 'HR'
  REBUILD_TYPE := NULL;    -- either 'C' or 'R'
  TABLESPACE_NAME := NULL; -- optional new tablespace name if desired

  REBUILD_USER_INDEXES(
    USER_NAME => USER_NAME,
    REBUILD_TYPE => REBUILD_TYPE,
    TABLESPACE_NAME => TABLESPACE_NAME
  );
END;

Note

The above code provides a very simplistic approach to index rebuilding as it rebuilds all indexes of a user. In order to determine the indexes in your database that would really benefit from rebuilding you need to run the script available from Oracle Metalink Note:122008.1.

Where is the Oracle Database alert log located ?

This is something I keep forgetting so I think that I may as well add it here.

On my Linux system the alert log is located in $ORACLE_HOME/admin/$ORACLE_SID/bdump while the exact same path -- with "\" instead of "/" -- is used for Windows.

The directory where the alert.log found is determined by the background_dump_dest initialization parameter: So the ultimate way to find it is by issuing an SQL command like :

select value 
    from v$parameter 
    where name = 'background_dump_dest';

Needless to say that the alert.log's name is alert.log and that it is a simple text file that can be opened using any text editor and that you can delete it or shrink it online.

Oracle Table containing the list of all countries

I wanted to create a table containing all country codes and countries.so I set off looking for the list of all two letter country codes. I have to admit that today was my lucky day since I ended up finding not only the list but also ready made SQL code to create and populate a MySQL table ready to cut and paste into your PHPMyAdmin SQL window. The link for the MySQL version can be found here

The truth of the matter was that I needed this for Oracle, so cutting, pasting and dining a bit of editing resulted to the following code :

---

CREATE TABLE COUNTRY (
 COUNTRY_ID NUMBER(*,0) NOT NULL ENABLE,
 COUNTRY_CODE VARCHAR2(10 BYTE) NOT NULL ENABLE,
 COUNTRY VARCHAR2(4000 BYTE) NOT NULL ENABLE,
 CURRENCY VARCHAR2(4 BYTE),
 CONSTRAINT "COUNTRY_PK" PRIMARY KEY (COUNTRY_ID) ENABLE,
 CONSTRAINT "COUNTRY_CODE_UNIQUE" UNIQUE (COUNTRY_CODE) ENABLE
);

Automatic configuration of SQL Plus on start-up

This is something I picked up from Oracle PL/SQL Programming by Steven Fewerstein and Bill Prybil.

When you start sqlplus the program reads configuration data from two files:

• $ORACLE_HOME/sqlplus/admin/glogin.sql
• ./login.sql

Since starting sqlplus from a directory that always contains an appropriate login.sql file isn't always possible, Bill recommends editing the glogin.sql. This is what the last lines my glogin sql look like :

---

-- Additional Settings by Bill Prybil
SET LINESIZE 132
SET PAGESIZE 999

-- Change the editor to vi if you don't do that sqlplus will use the editor from the $EDITOR
-- environment variable 
DEFINE _EDITOR = /usr/bin/vim

-- Format columns commonly retrieved from data dictionary
COLUMN segment_name FORMAT A30 WORD_WRAPP
COLUMN object_name FORMAT A30 WORD_WRAPP

-- set the sql prompt
SET SQLPROMPT "_USER'@'_CONNECT_IDENTIFIER >"

Oracle 10g SQL Script to list the connected users

OK, I know that EM can give you the same result in much prettier form, but let's keep that just in case.

---

SET LINESIZE 200
SET PAGESIZE 66

SELECT s.username, s.logon_time, s.machine, s.osuser, s.program
FROM v$session s, v$process p, sys.v_$sess_io si
WHERE s.paddr = p.addr(+) AND si.sid(+) = s.sid AND s.type='USER';

Oracle 10g Moving Data across tablespaces

Moving a table named my_table to a new tablespace named dest_data is a new feature of Oracle 10g and can be accomplished using the following command in SQLPlus:

SQL> alter table my_table move tablespace my_data;

Moving an index to a different table space is performed as follows :

SQL>alter index my_index rebuild tablespace my_data;

Oracle 10g on Linux Shell Variables required for proper operation

This is an extract from the .profile of the oracle user on a Linux machine (running SLES9) where Oracle 10g Release 2 (10.2.0.1.0) database enterprise edition is already installed. The variables required for correct operation of the database are the following

---

#
# Oracle Database 10g client related entries
#
export ORACLE_OWNER=oracle
export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/ctx/lib
export LIB_PATH=$LD_LIBRARY_PATH:/usr/lib
export NLS_LANG=AMERICAN_GREECE.EL8ISO8859P7
export NLS_DATE_FORMAT='DD-MM-YYYY HH24:MI:SS'
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/ctx/bin:$ORACLE_HOME/OPatch:$PATH
export ORACLE_SID=mydb

Notes

1. NLS_DATE_FORMAT is to allow rman display time information when listing backups
2. NLS_LANG is to allow oracle software to display messages in a specific language (here American English), use regional settings for a specific country (Greece) and handle data encoded in a specific format (here iso8859-7).
3. Forgetting to set the LD_LIBRARY_PATH has proved the root of many evil things
4. The same values can also be used for installations of an oracle application server version 10.1.3.x. Just remove the $ORACLE_HOME/ctx/lib for the $LD_LIBRARY_PATH variable
