From: Jason Waghorn <j_waghorn@yahoo.com.yahoo.com Newsgroups: email Date: Mon, 18 Nov 2004 14:31:37 +0000 (UTC) Subject: Конвертация Oracle10g non-ASM database в ASM database Державец Борис <dba477@list.ru.list.ru прислал комментарий к англоязычной статье: -------------------------------------------------------------- В техническом плане статья просто следует документации по RMAN в версии 10g. Однако, сама процедура гораздо легче для понимания когда читаешь статью, чем когда работаешь с документацией.Автор опускает процедуру перемещения Flash Recovery Area в ASM,либо просто педпочитает оставить область на файловой системе.Техническиий английский для понимания не сложен. В отношении ASM в версии Oracle10g, мне известна только англоязычная статья см. https://www.opennet.ru/opennews/art.shtml?num=4589 пункт 2. -------------------------------------------------------------- Статью также можно найти по адресу http://www.linuxgazette.com/node/view/9598 Converting Oracle10g non-ASM database to ASM This article is technical exercise following general guidelines of Oracle 10g Rman's Reference Manual.However,two times I was unable to reproduce instructions from Reference and had to manage on my own . The new Recovery Manager features in version 10g providing ability to migrate database from file system into AMS looks very impressive. Make sure ASM instance is up. Suppose also ASM volume group +DATA1 has been already created. Create database "convdata" with "dbca" in /u02/oradata.

    Вместо:-

    $cp /u01/app/oracle/admin/convdata/pfile/init.ora.929200412032 \
    > $ORACLE_HOME/dbs/initconvdata.ora
    $cd $ORACLE_HOME/dbs
    Add following entries to initconvdata.ora :-  
    CONTROL_FILES='+DATA1/controlf01'  
    DB_CREATE_FILE_DEST='+DATA1'  
    DB_CREATE_ONLINE_LOG_DEST_1='+DATA1'  
    $ mv spfileconvdata.ora spfileconvdata.ora.orig

    Выполним:-

    SQL> create pfile='$ORACLE_HOME/dbs/inittest.ora' from
      2  spfile='$ORACLE_HOME/dbs/spfiletest.ora'
      3  /

    File created.
    $cd $ORACLE_HOME/dbs
    $vi inittest.ora
    Add entries:-

    *.CONTROL_FILES='+DATA1/controlf01'
    *.DB_CREATE_FILE_DEST='+DATA1'
    *.DB_CREATE_ONLINE_LOG_DEST_1='+DATA1'

    Save file
    $mv spfiletest.ora spfiletest.ora.orig
    SQL> shutdown immediate;
    SQL> startup nomount
    SQL> create spfile='$ORACLE_HOME/dbs/spfiletest.ora' from
      2  pfile='$ORACLE_HOME/dbs/inittest.ora'
      3  /
    File created.

    Действие JWH:-

    Perform backup of database to be able remove old redo logs  

    Можно избежать если перед ASM конвенртацией активировать "Autoarchiving". В этом случае:-
    SQL> alter system switch logfile;
    будет приводить к архивированию предыдущего
    Redolog файла.
