DBNEWID database utility March 23, 2007

DBNEWID is a database utility that can change the internal database identifier (DBID) and the database name (DBNAME) for an operational database

What Is the DBNEWID Utility?

Prior to the introduction of the DBNEWID utility, you could manually create a copy of a database and give it a new database name (DBNAME) by re-creating the control file. However, you could not give the database a new identifier (DBID). The DBID is an internal, unique identifier for a database. Because Recovery Manager (RMAN) distinguishes databases by DBID, you could not register a seed database and a manually copied database together in the same RMAN repository. The DBNEWID utility solves this problem by allowing you to change any of the following:

  • Only the DBID of a database
  • Only the DBNAME of a database
  • Both the DBNAME and DBID of a database

Untuk yang menggunakan Oracle 10g R2, mungkin pernah mengalami hal dimana kita dapat dengan sukses connect menggunakan SQL*Plus, namun pada saat mencoba menjalankan aplikasi, kita kadang bisa connect kedatabase atau sama sekali tidak bisa terhubung dengan database.

Berikut ini mungkin bisa membantu mengatasi masalah anda.

  1. Set INBOUND_CONNECT_TIMEOUT_listener_name = 0 pada listener.ora
  2. Set SQLNET.INBOUND_CONNECT_TIMEOUT = 0 pada sqlnet.ora pada server
  3. Stop dan start database beserta dengan listernernya
  4. Test kembali aplikasi anda, apakah sudah berhasil connect ke database

Untuk melihat apakah nilai INBOUND_CONNECT_TIMEOUT pada listernet sudah berubah bisa dengan menggunakan:

LSNRCTL> show inbound_connect_timeout
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.16.9.11)(PORT=1521)))
LISTENER parameter "inbound_connect_timeout" set to 0
The command completed successfully

Thrown when the IP address of a host cannot be determined June 16, 2006

Pada saat installasi Oracle Client 10g Release 1 mungkin pernah ada yang mengalami error “Thrown when the IP address of a host cannot be determined” dan process berhenti pada saat “Processing Oracle Net Configuration Assistant 10…“, hal ini terjadi pada computer yg terhubung ke jaringan dan menggunakan dynamic IP dari DHCP, sepertinya oracle installer mencoba untuk membaca ip address pada file hosts yang terdapat di folder %WINDIR%\system32\drivers\etc\. dan hanya mendapatkan entry localhost seperti terlihat sebagai berikut:

127.0.0.1    localhost

Nah solusinya yaitu dengan menambahkan entry baru berupa ip address yg didapat dari DHCP, ini dapat dilihat dengan menggunakan perintah “ipconfig /all” pada command prompt dan hasilnya akan terlihat seperti berikut:

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix: jkt.indooracle.net
  Description . . . . . . . . . : AMD PCNET Family PCI Ethernet Adapter
  Physical Address. . . . . . . : 00-0C-29-89-A6-FC
  Dhcp Enabled. . . . . . . . . : Yes
  Autoconfiguration Enabled . . : Yes
  IP Address. . . . . . . . . . : 192.168.0.86
  Subnet Mask . . . . . . . . . : 255.255.255.0
  Default Gateway . . . . . . . : 192.168.0.10
  DHCP Server . . . . . . . . . : 192.168.0.10
  DNS Servers . . . . . . . . . : 192.168.0.10
  Lease Obtained. . . . . . . . : Thursday, June 08, 2006 4:08:36 PM
  Lease Expires . . . . . . . . : Thursday, June 08, 2006 10:08:36 PM

Dari atas terlihat ip address untuk computer yg digunakan adalah 192.168.0.86, maka tambahkan ip address tersebut pada file hosts, sehingga akan terlihat seperti berikut:

127.0.0.1       localhost
192.168.0.86    vmware    vmware.jkt.indooracle.net

Sekarang process installasi Oracle Client 10g Release 1 dapat dilanjutkan kembali dengan normal tanpa error.

Autotrace in SQLPLUS April 20, 2006

From Thomas Kyte about autotrace:
Here is what I like to do to get autotrace working:

  • cd $oracle_home/rdbms/admin
  • log into sqlplus as system
  • run SQL> @utlxplan
  • run SQL> create public synonym plan_table for plan_table
  • run SQL> grant all on plan_table to public
  • exit sqlplus and cd $oracle_home/sqlplus/admin
  • log into sqlplus as SYS
  • run SQL> @plustrce
  • run SQL> grant plustrace to public

You can replace public with some user if you want. by making it public, you let anyone trace using sqlplus (not a bad thing in my opinion).

About Autotrace
You can automatically get a report on the execution path used by the SQL optimizer and the statement execution statistics. The report is generated after successful SQL DML (that is, SELECT, DELETE, UPDATE and INSERT) statements. It is useful for monitoring and tuning the performance of these statements.

How to change database character set April 4, 2006

Posted by indooracle in Solving problem, Tutorial, Uncategorized.

Catat/backup nilai dari parameter sebelum melakukan perubahan, dengan tujuan agar apabila diinginkan dapat mengembalikan nilai parameter tersebut ke nilai awalnya.

show parameters JOB_QUEUE_PROCESSES;
show parameters AQ_TM_PROCESSES;

Kemudian dilanjutkan dengan process ALTER DATABASE untuk mengubah character set.

STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE CHARACTER SET new_character_set;
SHUTDOWN IMMEDIATE; -- or SHUTDOWN NORMAL;
STARTUP;

Jika dibutuhkan kita dapat mengubah kembali nilai dari JOB_QUEUE_PROCESSES dan AQ_TM_PROCESSES.

ALTER SYSTEM SET JOB_QUEUE_PROCESSES = old_job_queue_processes_value;
ALTER SYSTEM SET AQ_TM_PROCESSES = old_aq_tm_processes_value;
