In this episode of daily DBA, I pick up 6 important #DBA related questions and give my answers! Do not forget to checkout BONUS QUESTION at the end of the video!
00:00 Intro
02:35 What is the difference between local partition Index and Global partition Index?
05:52 I have two databases on one server. There is only one listener that accepts connections for both databases. How can I configure separate listeners for the databases?
08:42 What are the performance options for a fast index rebuild?
12:19 Before RMAN backup starts, what preparations are done inside the RMAN..?
16:52 A new schema was created with USERS as the default tablespace instead of TS_E6B. There are objects already created in the USERS tablespace with around 140 GB. How can I move the objects related with that schema to the correct schema tablespace TS_E6B?
18:36 When I query v$sql or v$sqlarea, I do not see the details about one SQL ID. How can I see history SQL queries and find a specific SQL with SQL ID?
Bonus Question
20:59 I am confused between Oracle RAC and Oracle Golden Gate. Which one do you recommend and why?

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 года назад
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 года назад
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;

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

@dbagenesis

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
