Sissejuhatus

iAS 10.1.2 infrastruktuur koosneb kahest osast, mis sisaldavad selliseid komponente

OIM - Oracle Indentity Management

OID - Oracle Internet Directory
SSO - OracleAS Single Sign-On
DAS - Oracle Delegated Administration Services
DIP - Oracle Directory Integration and Provisioning
OCA - OracleAS Certificate Authority

OracleAS Metadata Repository

Product metadata - sisaldab baasi skeeme rakenduskihi Portal ja Wireless komponentide kohta
OID Metadata - sisaldab skeeme infrastruktuuri OID, SSO ja OCA komponentide kohta
Management metadata - sisaldab DCM (Distributed Configuration Management) kohta

iAS komponente saab paigaldada

erinevates mahtudes, st jättes osa komponente paigaldamata kui nendega seotud funktsionaalsust ei ole tarvis
paigaldada mitmes eksemplaris eesmärgiga tõsta süsteemi jõudlust ning redundantsust

Käesolevas tekstis esitatakse järgnevus kuidas paigaldada iAS'i kõik komponendid kasutades välist Oracle 10R2 RAC ASMseadistuses andmebaasi ning sealjuures komponendid paigatakse 2008 aasta keskpaigas olemasolevate paikadega.

10R2 RAC ASM baas - 10.2.0.4.0
10R1 iAS - 10.1.2.3.0

Järgneva eelduseks on et on olemas

paigatud SLES10 SP1 64bit operatsioonisüsteem
10R2 RAC ASM seadistuses andmebaas 10.2.0.4.0

Kõik iAS 10.1.2 tarkvara tuleb 64bit operatsioonisüsteemi puhul käivitada

 linux32 bash

shellist. Seda kas shell on õige saab shelli töötamise ajal küsida

 $ arch 
 x86_64
 $ linux32 bash
 $ arch 
 i686

Protseduuri ülevaade

Tarkvara paigaldamine toimub sellises järjekorras

MRCA (Metadata Repository Configuration Assistant) abil laaditakse olemasolevasse andmebaasi (ingl. k. existing database) MR skeemid, kasutades MRCA versiooni 10.1.2.0.3.
Paigaldatakse infrastruktuuri 10.1.2.0.2 komponendid.
Paigaldatakse rakenduskihi 10.1.2.0.2 komponendid.
Paigatakse infrastruktuur versioonile 10.1.2.3.0
Paigatakse rakenduskiht versioonile 10.1.2.3.0
Paigatakse metadata repositori versioonile 10.1.2.3.0

Kusjuures

kasutaja oracle kodukataloog on /home/oracle
rakenduste kataloogid asuvad kataloogis /u01/app/oracle/product/10.1.2
inventory kataloog on /u01/app/oracle/oraInventory

MRCA paigaldamine

MRCA abil MR skeemide laadimiseks olemasolevasse 10R2 andmebaasi tuleb teha sellised ettevalmistused, numbrid viitava Metalink'i (http://metalink.oracle.com/) nootidele, neile ligipääsuks peab olema Metalink süsteemis kasutada kasutaja

362983.1 - MRCA 10.1.2.0.3 and Oracle Database 10g Release 2 (10.2)

Kasutada MRCA (Metadata Repository Creation Assistant) versiooni 10.1.2.0.3, http://www.oracle.com/technology/software/products/ias/htdocs/101202.html

 $ cksum as_linux_x86_mrca_101203.cpio
 1961190085 480973824 as_linux_x86_mrca_101203.cpio

Pakime MRCA paigaldusmaterjali lahti

 $ cpio -dmvi < as_linux_x86_mrca_101203.cpio

MRCA kasutamiseks tuleb esmalt MRCA ise paigaldada, nt kataloogi

 /u01/app/oracle/product/10.1.2/mrca

Veenduge, ega Oracle'ga seatud keskkonnamuutujaid ei ole kirjeldatud, ega esine vatavaid teid PATH'is

 $ env | grep ORA*
 $ echo $PATH

Näiteks sellise skriptiga /home/oracle/system/env.sh saab nad eemaldada

 unset ENV
 unset ORA_CRS_HOME
 unset ORA_DB_HOME
 unset ORACLE_SID
 unset ORA_NLS10
 unset ORACLE_BASE
 unset ORA_IAS_HOME
 unset ORACLE_HOME
 unset LD_LIBRARY_PATH
 export PATH=/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin
 unset CLASSPATH
 unset TNS_ADMIN
 unset AGENT_HOME
 unset ORA_ASM_HOME
 unset ORACLE_HOSTNAME

ning öelda

 $ . ./system/env.sh

Ja käivitada installer

 $ ./runInstaller

Kui kõnealuses arvutis on MRCA installer esimene Oracle programm, siis küsitakse inventory asukohta

ning moodustatakse kaks faili

 # /u01/app/oracle/oraInventory/orainstRoot.sh 
 Creating the Oracle inventory pointer file (/etc/oraInst.loc)
 Changing groupname of /u01/app/oracle/oraInventory to oinstall.

Seejärel tuleb näidata millisesse kataloogi tarkvara paigaldatakse

Keelevalikud, installeri kasutajaliidese keele osas

Seejärel sooritab installer standarse operatsioonisüsteemi parameetrite kontrolli, mille tulemus võiks olla näiteks selline

Siit on näha järgmised probleemid

 * Checking for msgmni=2878; found msgmni=16.      Failed <<<< - tuleb seada kernel.msgmni parameeter
 * mõni pakett on puudu - neid võib praktiliselt ignoreerida kuna me kasutame tegelikult SLES10 operatsioonisüsteemi

Peale parameetri seadmist käsuga

 # sysctl -w kernel.msgmni=2878

ning faili /etc/sysctl.conf lisades.

Peale installeri töö katkestamist ja enne uuesti käivitamist tuleb vahepeal eemaldada failisüsteemist tekkinud kataloog

 $ rm -rf /u01/app/oracle/product/10.1.2/mrca

Küsitakse, kas installeri paigaldamise järel asutakse koheselt andmebaasi ettevalmistama, vastame eitavalt, et protseduurid lahus hoida

Näidatakse tehtud otsustusi

Ja toimub tarkvara paigaldamine

Paigalduse lõpul tuleb käivitada juurkasutajana skript

 # /u01/app/oracle/product/10.1.2/mrca/root.sh

Teatatakse, et paigaldus on lõppenud

Installeri sulgemine toimub justkui ebaloomulikult öeldes Exit, aga nii ta on

MRCA abil MR skeemide laadimine olemasolevasse andmbaasi
