DB - Transportable Tablespaces x-Platforms


Versao Portuguesa



In this post i'm sharing how to copy data /tablespaces between databases in different platforms
as I've no HP-UX here at home .. I will have to convert a tablespace to HP-UX, then to convert the datafile back to Linux


I will execute the next step to get this done:
1 - Source setup - create a tablespace, user and a table with data
2 - Export the tablespace
3 - Convert the tablespace to 'HP-UX IA (64-bit)'
4 - Remove the Tablespace from the source
5 - Prepare the import
6 - Convert datafile from 'HP-UX IA (64-bit)' > 'Linux IA (32-bit)'
7 - Import the tablespace in the destination
8 - Validate the data


1 - Source setup - create a tablespace, user and a table with data


Criar Tablespace : xpto : Data File : xpto.bdf
Criar user teste : xpto
Tabela : xpto.users

SQL> create tablespace xpto datafile 'xpto.bdf' size 10m autoextend on next 10m maxsize 100m;
Tablespace created.

SQL> create user xpto identified by xpto default tablespace xpto quota unlimited on xpto;
User created.

SQL> create table xpto.users as select * from dba_users;
Table created.



2 - Export the tablespace


Standard expdp - create a directory + expdp ( the TS needs to be read only)

SQL> create directory DIR_TTS as '/home/oracle';
Directory created.

SQL> alter tablespace xpto read only;
Tablespace altered.

SQL> !expdp DIRECTORY=DIR_TTS TRANSPORT_TABLESPACES='XPTO' DUMPFILE=tts_xpto.dmp

3 - Convert the tablespace to 'HP-UX IA (64-bit)'


Sofar - as the same as copy between same platforms
Now start the diferences, to carry one lets generate a data file with RMAN for 'HP-UX IA (64-bit)'

RMAN> CONVERT TABLESPACE xpto TO PLATFORM 'HP-UX IA (64-bit)' FORMAT '/home/oracle/xpto_%U';

Starting conversion at source at 16-FEB-18
using channel ORA_DISK_1
channel ORA_DISK_1: starting datafile conversion
input datafile file number=00006 name=/home/oracle/xpto.bdf
converted datafile=/home/oracle/xpto_data_D-xTTS_I-2336971890_TS-XPTO_FNO-6_03srcukf
channel ORA_DISK_1: datafile conversion complete, elapsed time: 00:00:01
Finished conversion at source at 16-FEB-18



4 - Remove the Tablespace from the source


As we have tablespace backup, and to let remove the tablespace from the source / and load it again from the 'HP-UX IA (64-bit)' data file,

SQL> drop tablespace xpto including contents and datafiles;
Tablespace dropped.



5 - Prepare the import


Is need to copy the data files and and dump files to destionation
it can be done using standard commands scp / ftp .. or usubf a share FS.
As this is case is the same box .. I will skip it


6 - Convert datafile from 'HP-UX IA (64-bit)' > 'Linux IA (32-bit)'



Now let's convert the datafile from ( step 3) from 'HP-UX IA (64-bit)' > 'Linux IA (32-bit)'

SQL> SELECT PLATFORM_NAME FROM V$TRANSPORTABLE_PLATFORM
WHERE PLATFORM_ID = ( SELECT PLATFORM_ID FROM V$DATABASE );

PLATFORM_NAME
-----------------------------------------------------------------------------------------------------
Linux IA (32-bit)


RMAN> CONVERT FROM PLATFORM 'HP-UX IA (64-bit)'
DATAFILE '/home/oracle/xpto_data_D-xTTS_I-2336971890_TS-XPTO_FNO-6_03srcukf'
FORMAT '/home/oracle/XPTO_CONVERTED_FROM_HP_2_LINUX-32b';

Starting conversion at target at 16-FEB-18
using channel ORA_DISK_1
channel ORA_DISK_1: starting datafile conversion
input file name=/home/oracle/xpto_data_D-xTTS_I-2336971890_TS-XPTO_FNO-6_03srcukf
converted datafile=/home/oracle/XPTO_CONVERTED_FROM_HP_2_LINUX-32b
channel ORA_DISK_1: datafile conversion complete, elapsed time: 00:00:01
Finished conversion at target at 16-FEB-18



7 - Import the tablespace in the destination



Almost done - now is only run the impdp : the dmp file from ( step - 2) and the datafile from (step - 6)

$ impdp DIRECTORY=DIR_TTS DUMPFILE='tts_xpto.dmp' TRANSPORT_DATAFILES='/home/oracle/XPTO_CONVERTED_FROM_HP_2_LINUX-32b'

Import: Release 11.2.0.1.0 - Production on Fri Feb 16 17:35:14 2018

8 - 8 - Validate the data


After the impdp is complete we can connect and validate the data
And change the tablespace to "read write"

[oracle@ocm ~]$ sqlplus / as sysdba

37

SQL> alter tablespace xpto read write;
Tablespace altered.


SQL> col FILE_NAME form a100
SQL> select FILE_NAME, TABLESPACE_NAME from dba_data_files where TABLESPACE_NAME='XPTO';

FILE_NAME TABLESPACE_NAME

DB - How to monitor Oracle datapump jobs

These days there is lot of work around database migrations not only but mainly to cloud providers. One of the ways to migrate Oracle databases is using data pump (expdp/impdp). In general works fine, it allows an easy way to bring the database even different OS. It is always good to monitor the progress, to know where we are and estimate how long we are from the end. In this post, I am sharing some queries to help with database monitoring progress. The queries can be easily tailed to various scenarios. Starting with a simple one - the track the number of objects loaded during an import operation. When there is a massive amount of errors during the import. Drop and run the import again. The bellow query can be useful also to monitor the number of objects if we are dropping the users. Here, I’m making the assumption there were no other database activity in progress on the last 24 hours. select owner, count(0) from dba_objects where owner in ( select username from dba_users where created...

VM - Partilhar Pastas Windows - Linux

Neste post escrevo como partilhar pastas entre Windows (Host) e uma VM Guest, neste caso Linux. Ha algumas formas de fazer isto, esta parece me a mais facil. Seleccionar a Pasta Windows Na consola Virtual Box > Devices > Shared Folder Seleccionar a pasta windows para partilhar no Linux   O   Montar a pasta Windows na VM Ha duas opcoes : 1) Reiniciar a VM (Auto-mount) 2) Linha de comando [root@host ~]# mkdir -p /u01/stage/win_ebs_sw [root@host ~]# chmod 777 /u01/stage/win_ebs_sw [root@host ~]# mount -t vboxsf Oracle_EBS /u01/stage/win_ebs_sw/ [root@host ~]# ls /u01/stage/win_ebs_sw ebs_weblogic_webtier [root@host ~]# df -h /u01/stage/win_ebs_sw Filesystem Size Used Avail Use% Mounted on Oracle_EBS 895G 494G 401G 56% /u01/stage/win_ebs_sw Guardar a Configuracao no /etc/fstab para tornar as alteracoes permanentes.

DB – How to monitor Oracle database long ops ?

As DBAs, some questions we are often asked and to be fair we ask ourselfs when we are doing massive operations, are : Is the database doing something? How long the database takes to complete the task? There a data dictionary view, GV$SESSION_LONGOPS whom is really usefull for monitoring and to provide estimated time to get the task done. Starting with a first example, a query for general propose . set lines 240 col message form a100 col opname form a50 select * from ( select round(l.sofar/l.totalwork*100,2) as complete, --l.* l.sid, --l.opname, l.message, l.start_time, l.time_remaining/60 "minuts remaining", l.elapsed_seconds from gv$session_longops l where totalwork !=0 ) where complete < 100; The view is also usefull on specific operations such as Oracle Recovery Manager (RMAN) jobs monitoring, this query returns information about backup,restore and recovery. select sid, serial#,opname, context, sofar, totalwork, round(sofar/totalwork*100,2) "%_complet...
