Membuat Backup Logic dengan Menggunakan Shell Scripting

Berikut ini Script sederhana untuk membuat logical backup dimana file backup akan langsung di zip dan backup file yang lebih dari dua hari akan di delete . Mudah-mudahan bermanfaat :)

Kernel Parameters

Setelah sukses dengan instalasi Linux OS Versi 5 pastikan nilai-nilai parametrer dalam file /etc/sysctl.conf sesuai dengan rekomendasi dari oracle agar Instalasi RAC berjalan dengan lancar, login sebagai root untuk melakukan perubahan kernel, berikut ini nilai kernel yang di rekomendasikan oleh Oracle :

Setting Kernel untuk Oracle 11g R1:
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.aio-max-size =1048576
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

Setting Kernel untuk Oracle 11g R2:
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.aio-max-size =1048576
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

Bagaimana Cara Merubah IP Interconnect/Public Interface di Clusterware

Berikut step by step cara merubah IP Interconnect di Oracle RAC, Sebaiknya di lakukan di mesin test terlebih dahulu sebelum di implementasikan di mesin Production :)

Cek konfigurasi dari interfaces yang di gunakan oleh cluster saat ini :

$ $CRS_HOME/bin/oifcfg getif

Berikut ini contohnya :

$ $CRS_HOME/bin/oifcfg getif
eth4 192.168.99.0 global cluster_interconnect
pub_bond 10.165.77.0 global public

Stop the database and nodeapps on both nodes.

$ srvctl stop database -d NAMA_DATABASE
$ srvctl stop nodeapps -n NAMA_NODE1
$ srvctl stop nodeapps -n NAMA_NODE2

Dibawah ini contohnya :

$ srvctl stop database -d TESTDB
$ srvctl stop nodeapps -n TESTDB1
$ srvctl stop nodeapps -n TESTDB2

Untuk merubah interface adalah dengan delete interface yang di gunakan saat ini lalu tambahkan interface yang baru

$ $CRS_HOME/bin/oifcfg delif -global interface_name

Tambahkan interface Baru

$CRS_HOME/bin/oifcfg setif -global new_if/network_number:cluster_interconnect

Berikut ini contohnya :

$ $ORA_CRS_HOME/bin/oifcfg getif
eth4 192.168.99.0 global cluster_interconnect
pub_bond 10.165.199.0 global public
$ $ORA_CRS_HOME/bin/oifcfg delif -global eth4
$ $ORA_CRS_HOME/bin/oifcfg getif
pub_bond 10.165.77.0 global public
$ $CRS_HOME/bin/oifcfg setif -global int_bond/192.168.99.0:cluster_interconnect
Confirm the changes have taken place.
$ $CRS_HOME/bin/oifcfg getif
int_bond 192.168.99.0 global cluster_interconnect
pub_bond 10.165.77.0 global public

Merubah Public Interface and VIP

Jika yang dirubah adalah Public interface maka akan merubah VIP (Virtual IP). Merubah VIP termasuk juga memodifikasi tiap node.

Berikut ini Step-stepnya :

$ srvctl stop nodeapps -n TESTDB1
$ srvctl stop nodeapps -n TESTDB2

Confirm current configuration.

$ $CRS_HOME/bin/oifcfg getif
eth1 10.165.77.0 global public
eth4 192.168.99.0 global cluster_interconnect

Ubah public interface dari eth1 ke pub_bond

$ $CRS_HOME/bin/oifcfg delif -global eth1
$ $ORA_CRS_HOME/bin/oifcfg getif
eth4 192.168.99.0 global cluster_interconnect
$ $ORA_CRS_HOME/bin/oifcfg setif -global pub_bond/10.165.77.0:public
$ srvctl modify nodeapps -n TESTDB1 -A 10.165.77.152/255.255.255.0/pub_bond
PRKO-2117 : This command should be executed as the system privilege user.

[oracle@nycdb01 ~]$ su -
Password:
[root@nycdb01 oracle]# srvctl modify nodeapps -n nycdb01 -A 10.165.77.152/255.255.255.0/pub_bond
[root@nycdb01 oracle]# srvctl modify nodeapps -n nycdb02 -A 10.164.227.151/255.255.255.0/pub_bond

Verifikasi

# $CRS_HOME/bin/crs_stat -p ora.TESTDB1.vip | grep USR_ORA_IF
USR_ORA_IF=pub_bond
# $CRS_HOME/bin/crs_stat -p ora.TESTDB2.vip | grep USR_ORA_IF
USR_ORA_IF=pub_bond

Trik Jika Lupa password Root di mesin HP-UX

Lupa password root ? . . . he he he bikin panik emang apalagi klo itu adalah mesin production, berikut ini pengalaman saya waktu lupa password root di mesin dan OS nya juga HP-UX , dibawah ini adalah tampilan yang saya capture ketika booting langsung dari management console . Proses penggantian passwordnya ada pada bagian yang saya bikin tebal hurufnya (perl script di bagian bawah ) . Berikut ini proses lengkapnya mudah-mudahan bermanfaat :

REM

REM This script can be run by any user .
REM

REM This script is intended to run with Oracle8i.

Insert Menggunakan Metode Exchange Partition

Berikut ini contoh sederhana penggunaan metode exchange partition :

Create table destination
------------------------------
CREATE TABLE call_BEBEK (
id NUMBER(12,6),
v1 VARCHAR2(10),
data VARCHAR2(100)
)
PARTITION BY RANGE(id) (
PARTITION P_1 VALUES LESS THAN (2)
) TABLESPACE users;

set serveroutput on;
set heading off;
set feedback off;
set linesize 800;
set pagesize 999;
declare
v_no number:=1;
begin
DBMS_OUTPUT.ENABLE(1000000);
for i in 1..31 loop
dbms_output.put_line('ALTER TABLE call_bebek ADD PARTITION P_'||to_char(v_no+i) ||' VALUES LESS THAN ('||TO_CHAR (v_no+1+i)||') TABLESPACE USERS;');
dbms_output.put_line(' ');

end loop;
end;

ALTER TABLE call_bebek ADD PARTITION P_2 VALUES LESS THAN (3) TABLESPACE USERS;

ALTER TABLE call_bebek ADD PARTITION P_3 VALUES LESS THAN (4) TABLESPACE USERS;

ALTER TABLE call_bebek ADD PARTITION P_4 VALUES LESS THAN (5) TABLESPACE USERS;

ALTER TABLE call_bebek ADD PARTITION P_5 VALUES LESS THAN (6) TABLESPACE USERS;

ALTER TABLE call_bebek ADD PARTITION P_6 VALUES LESS THAN (7) TABLESPACE USERS;

ALTER TABLE call_bebek ADD PARTITION P_7 VALUES LESS THAN (8) TABLESPACE USERS;

ALTER TABLE call_bebek ADD PARTITION P_8 VALUES LESS THAN (9) TABLESPACE USERS;

ALTER TABLE call_bebek ADD PARTITION P_9 VALUES LESS THAN (10) TABLESPACE USERS;

Create local Index
---------------------------
CREATE index bebek_id on call_bebek(id) local tablespace users;

create table source
--------------------------
CREATE TABLE call_temp_BEBEK (
id NUMBER(12,6),
v1 VARCHAR2(10),
data VARCHAR2(100)
)TABLESPACE USERS;

Insert Data
----------------------------
INSERT /*+ append ordered full(s1) use_nl(s2) */
INTO call_temp_bebek
SELECT
TRUNC((ROWNUM-1)/500,6),
TO_CHAR(ROWNUM),
RPAD('X',100,'X')
FROM
all_tables s1,
all_tables s2
WHERE
ROWNUM <= 10000;

Update record to syncronize with table partition
-----------------------------------------------------
Update call_temp_bebek
set ID=8

Insert using exchange command (Metode ini berjalan dua arah dari partition ke non partition atau sebaliknya dengan perintah yang sama dibawah ini)
------------------------------------------------------------------------------------------------------------------------------------------------------
ALTER TABLE CALL_BEBEK
EXCHANGE PARTITION P_8 WITH TABLE call_temp_bebek;

ALTER TABLE sales
EXCHANGE PARTITION feb97 WITH TABLE sales_feb97
WITHOUT VALIDATION;

Service Level Agreement (SLA)

Apa seh SLA itu dan apa aja isi dai SLA ? . . . SLA adalah bagian dari perjanjian layanan secara keseluruhan antara 2 dua entitas untuk peningkatan kinerja atau waktu pengiriman harus di perbaiki selama masa kontrak. Dua entitas tersebut biasanya dikenal sebagai Service Provider dan Client, dan dapat melibatkan perjanjian secara hukum karena melibatkan uang, atau kontrak lebih informal antara unit-unit bisnis internal.

SLA ini biasanya terdiri dari beberapa bagian yang mendefinisikan tanggung jawab berbagai pihak, dimana layanan tersebut bekerja dan memberikan garansi, dimana jaminan tersebut bagian dari SLA memilikitingkat harapan yang disepakati, tetapi dalam SLA mungkin terdapat tingkat ketersediaan, kemudahan layanan, kinerja, operasi atau tingkat spesifikasi untuk layanan itu sendiri. Selain itu, Perjanjian Tingkat Layanan akan menentukan target yang ideal, serta minimum yang dapat diterima.

Lalu apa seh isi dari SLA itu biasanya ? . . . Berikut ini biasanya yang terdapat dalam SLA :

Service Description
Hours of operation
User Response times
Incident Response times
Resolution times
Availability & Continuity targets
Customer Responsibilities
Critical operational periods
Change Response Times

Kesembilan items tersebut harus sudah di sepakati oleh kedua belah pihak (Service Provider dan Client)
