select c.SQL_ID, count(1) cnt, sql.sql_text

Monitoring open cursors

I believe a lot of the confusion about open cursors vs. cached cursors comes from the names of the Oracle dynamic performance views used to monitor them. v$open_cursor shows cached cursors, not currently open cursors, by session. If you're wondering how many cursors a session has open, don't look in v$open_cursor. It shows the cursors in the session cursor cache for each session, not cursors that are actually open.

To monitor open cursors, query v$sesstat where name='opened cursors current'. This will give the number of currently opened cursors, by session:

--total cursors open, by session
select a.value, s.username, s.sid, s.serial#
from v$sesstat a, v$statname b, v$session s
where a.statistic# = b.statistic#  and s.sid=a.sid
and b.name = 'opened cursors current';

If you're running several N-tiered applications with multiple webservers, you may find it useful to monitor open cursors by username and machine:

--total cursors open, by username & machine
select sum(a.value) total_cur, avg(a.value) avg_cur, max(a.value) max_cur, 
s.username, s.machine
from v$sesstat a, v$statname b, v$session s 
where a.statistic# = b.statistic#  and s.sid=a.sid
and b.name = 'opened cursors current' 
group by s.username, s.machine
order by 1 desc;


Monitoring the session cursor cache

v$sesstat also provides a statistic to monitor the number of cursors each session has in its session cursor cache.

--session cached cursors, by session
select a.value, s.username, s.sid, s.serial#
from v$sesstat a, v$statname b, v$session s
where a.statistic# = b.statistic#  and s.sid=a.sid
and b.name = 'session cursor cache count' ;

You can also see directly what is in the session cursor cache by querying v$open_cursor. v$open_cursor lists session cached cursors by SID, and includes the first few characters of the statement and the sql_id, so you can actually tell what the cursors are for.

select c.user_name, c.sid, sql.sql_text
from v$open_cursor c, v$sql sql
where c.sql_id=sql.sql_id  -- for 9i and earlier use: c.address=sql.address
and c.sid=&sid;

To recover specific data blocks:
    Obtain the datafile numbers and block numbers of the corrupted blocks.
    The easiest way to locate trace files and the alert log is to connect SQL*Plus to the target database and execute the following query:

    SELECT NAME, VALUE 
    FROM   V$DIAG_INFO;

    Start RMAN and connect to the target database, which must be mounted or open.
    Run the SHOW ALL command to make sure that the appropriate channels are preconfigured.
    Run the RECOVER ... BLOCK command at the RMAN prompt, specifying the file and block numbers for the corrupted blocks.

    The following example recovers two blocks.
    RECOVER 
      DATAFILE 8 BLOCK 13 
      DATAFILE 2 BLOCK 19;

    You can also specify various options to control RMAN behavior. The following example indicates that only backups with tag mondayam will be used when searching for blocks. You could use the FROM BACKUPSET option to restrict the type of backup that RMAN searches, or EXCLUDE FLASHBACK LOG to restrict RMAN from searching the flashback logs.
    RECOVER 
      DATAFILE 8 BLOCK 13 
      DATAFILE 2 BLOCK 199
      FROM TAG mondayam;

Recovering All Blocks in V$DATABASE_BLOCK_CORRUPTION -> In this scenario, RMAN automatically recovers all blocks listed in the V$DATABASE_BLOCK_CORRUPTION view.

e bine sa dai un restart la server inainte de stergere ca sa fim siguri ca  nu mai useri cu obiecte temporare acolo.
1)DROP TABLESPACE WINMDB_TEMP INCLUDING CONTENTS AND DATAFILES;
dupa drop verifici daca l-a sters si de la nivelul sistemului de operare, pentru ca eu am observat ca nu il sterge tot timpu si de acolo, daca nu a reusit sa il stearga el automat il stergi tu manual. Cand incerci sa il stergi manual e posibil sa nu te lase sistemu de operare pentru ca oracle inca nu a notificat ca nu mai foloseste fisierul respectiv, in acest caz restart la server (serveru de oracle; serviciul restectiv) si apoi reincerci stergerea manuala
2)CREATE TEMPORARY TABLESPACE WINMDB_TEMP TEMPFILE 'D:\OraData\WINMDB2\WINMDB_TEMP.dbf' SIZE 5M REUSE AUTOEXTEND ON NEXT 512K MAXSIZE UNLIMITED;

2)CREATE BIGFILE TEMPORARY TABLESPACE WINMDB_TEMP TEMPFILE 'E:\OraData\WMEPREL\WINMDB_TEMP.dbf' SIZE 5M REUSE AUTOEXTEND ON NEXT 512K MAXSIZE UNLIMITED;
 LA MAX FILE SE POATE INCERCA SI 2T, 128G, 32M ...

de inlocuit calea fisierului din exemplul meu cu calea aferenta fiecarui caz particular.

Parametrii responsabili cu securitatea in oracle (se pot modifica conectat ca SYS, SYSTEM sau chiar WINMADMIN)

PASSWORD_LIFE_TIME -> nr.zile de valabilitate a parolei. Default = 180
PASSWORD_GRACE_TIME -> nr.zile perioada de gratie dupa expirarea parolei (se permite autentificare cu mesaj). Default = 7
PASSWORD_REUSE_TIME -> nr.zile dupa care o parola poate fi reutilizata
PASSWORD_REUSE_MAX -> nr.de schimbari de parola dupa care o parola poate fi reutilizata
PASSWORD_LOCK_TIME -> nr.zile user blocat dupa incercari consecutive de logare esuate. Default = 1
FAILED_LOGIN_ATTEMPTS -> nr.maxim de incercari consecutive de logare esuate. Default = 10

ORA-00600: internal error code, arguments: [kcratr_nab_less_than_odr], [1],[290], [63878], [63882], [], [], [], [], [], [], []

cold backup database files

 Alter database open fails with ORA-00600 kcratr_nab_less_than_odr
Db: 11.2.0.1

Symptoms
After Power Fail Alter database open fails with

ORA-00600: internal error code, arguments: [kcratr_nab_less_than_odr]

Changes
Power failure
Cause
There was a power failure causing logical corruption in controlfile

Solution

Option a
------------

SQL>Startup mount ;

SQL>Show parameter control_files

Query 1
------------

sql>select a.member,a.group#,b.status from v$logfile a ,v$log b where a.group#=b.group# and b.status='CURRENT'

Note down the name of the redo log

SQL>Shutdown abort ;

Take a OS Level back of the controlfile (This is to ensure we have a backup of current state of controlfile)

SQL>Startup mount ;

SQL>recover database using backup controlfile until cancel ;

Enter location of redo log shown as current in Query 1 when prompted for recovery

Hit Enter

SQL>Alter database open resetlogs ;

Option b
-----------


Recreate the controlfile using the Controlfile recreation script

With database in mount stage

rman target /

rman> spool log to '/tmp/rman.log';

Rman> list backup ;

Rman > exit

Keep this log handy

Go to sqlplus

SQL> Show parameter control_files

Keep this location handy.

SQL>oradebug setmypid

SQL>Alter session set tracefile_identifier='controlfilerecreate' ;

SQL>Alter database backup controlfile to trace ;

SQL>Oradebug tracefile_name ; --> This command will give the path and name of the trace file


Go to this location ,Open this trace file and select the controlfile recreation script with NO Resetlogs option


SQL>Shutdown immediate;


Rename the existing controlfile to _old ---> This is Important as we need to have a backup of existing controlfile since we plan to recreate it

SQL>Startup nomount

Now run the Controlfile recreation script with NO Resetlogs mode

SQL>Alter database open ;

For database version 10g and above

Once database is opened you can recatalog the rman backup information present in the list /tmp/rman.log using

Rman> Catalog start with '' ;
