  • Tracer une session Oracle

    Avant la 10G :

     

    Activer la trace :

    SQL> EXEC DBMS_SYSTEM.set_sql_trace_in_session(sid=>123, serial#=>1234, sql_trace=>TRUE);

    Désactiver la trace : SQL> EXEC DBMS_SYSTEM.set_sql_trace_in_session(sid=>123, serial#=>1234, sql_trace=>FALSE);

    Après la 10G :

    Activer la trace :
    SQL> EXEC DBMS_MONITOR.session_trace_enable(session_id=>1234, serial_num=>1234);
    SQL> EXEC DBMS_MONITOR.session_trace_enable(session_id =>1234, serial_num=>1234, waits=>TRUE, binds=>FALSE);
    

    Désactiver la trace :

    SQL> EXEC DBMS_MONITOR.session_trace_disable(session_id=>1234, serial_num=>1234);

  • Dataguard - refresh a physical standby dataguard from primary avec RMAN

     

    Steps to Refresh a Physical Standby Database with Changes Made to the Primary Database

     

    source : https://docs.oracle.com/en/database/oracle/oracle-database/18/spmss/refresh-a-physical-standby-db.html#GUID-828A4953-3F7E-4975-ADA4-5469D6794BB0

     le site inclus les prérequis que l'on oublie souvent:

     

    • Oracle Net connectivity is established between the physical standby database and the primary database.

      You can do this by adding an entry corresponding to the primary database in the tnsnames.ora file of the physical standby database.

    • The password files on the primary database and the physical standby database are the same.

    • The COMPATIBLE parameter in the initialization parameter file of the primary database and physical standby database is set to 12.0.

     

    ...

    4 . (For Active Data Guard only) Perform the following steps to recover redo data and open the physical standby database in read-only mode:

    ALTER DATABASE RECOVER MANAGED STANDBY DATABASE UNTIL CONSISTENT;

    ALTER DATABASE OPEN READ ONLY;

    ...

     

  • Dataguard - start and stop a standby database on server startup

    Source : https://www.orafaq.com/forum/t/122395/

     

    to start a standby database :

     

    #!/bin/bash
    ORA_HOME="/opt/oracle/920"
    ORA_OWNER="oracle"
    SQLCMD="sqlplus '/as sysdba'"
    LOGFILE="strt.log"
    cat startup.sql | su - $ORA_OWNER  -c "$SQLCMD" > $LOGFILE

     

    to shutdown a standby database :

    #!/bin/bash
    ORA_HOME="/opt/oracle/920"
    ORA_OWNER="oracle"
    SQLCMD="sqlplus '/as sysdba'"
    LOGFILE="sht.log"
    cat shutdown.sql | su - $ORA_OWNER  -c "$SQLCMD" > $LOGFILE

     

    startup.sql :

    startup nomount;
    alter database mount standby database;
    alter database recover managed standby database disconnect from session;

     

    shutdown.sql:

    alter database recover managed standby database cancel;
    shutdown immediate;
    exit
