    Hi Arun, thanks for helping out. Could you please provide the sequence of steps in right order to move table online to different tablespace with all attached objects if that table having indexes, partitions, LOBs all.

    • @dbagenesis
      @dbagenesis  3 ปีที่แล้ว

      Oracle 12.2 onward you can move the table as an online operation using ONLINE keyword. but it can't be used on a partitioned index-organized table or index-organized tables that have a column defined as a LOB, VARRAY, Oracle-supplied type, or user-defined object type.
      ALTER TABLE t1 MOVE ONLINE TABLESPACE users;

    Hi Arun, for question on moving table,can't we use expdp of schema,then allocate new tablespace to that user as default tablespace and import ,as this will take care of all the objects within schema.Only issue is all tables will be not available during this process,but we can use parallel option.?Can you please comment on my thought please.

    Great work Arun..
    I have upgraded (manually) my 11.2.0.4 database to 12.1.0.2 and also I have upgraded the dst_timezone to 18 .. But after running the post_upgrade_fixups.sql ... It's still showing old_time_zone.So, my question is whether this is some sort of bug in oracle 12.1 or do I need to upgrade to timezone to some other values??
    Please do respond... :)

    • @dbagenesis
      @dbagenesis  3 ปีที่แล้ว +1

      If still, changes are not reflecting Check the preupgrade_fixups.sql script and do the changes manually.
      UPGRADE DST TIME ZONE:
      1. Download the dst upgrade script from oracle
      unzip the file
      $ unzip DBMS_DST_scriptsV1.9.zip
      $ cd DBMS_DST_scriptsV1.9
      run countstatsTSTZ.sql script.
      SQL> spool countstatsTSTZ.log
      SQL> @countstatsTSTZ.sql
      SQL> spool off
      Purge the scheduler jobs
      SQL> exec dbms_scheduler.purge_log;
      Run upg_tzv_check.sql ( it will detect the highest installed DST patch automatically)
      SQL> spool upg_tzv_check.log
      SQL> @upg_tzv_check.sql
      SQL> spool off
      SQL> spool upg_tzv_apply.log
      Run upg_tzv_apply.sql ( It will do the actual dst upgrade)
      SQL> spool upg_tzv_apply.log
      SQL> @upg_tzv_apply.sql
      Once dst upgrade is successful , validate the time_zone(It should be 18)
      SQL> SELECT version FROM v$timezone_file;

      We are creating index on only few Columns of the table even though Index size is very much near to size of the table why?

      Happens sometimes! For small tables, the index size will be bigger than table size itself. ;)

      Good one! added question to upcoming episode. Meanwhile, find below your answer:
      - First you need to add disks to shared storage
      - use oracleasm utility to create ASM disks
      - Fire ASMCA to create ASM disk group
      - Allocate disks to disk group, define redundancy and mount diskgroup
      - The newly created disk group will be visible to database by default
