How to install Distributing OracleAS Infrastructure components using an existing database?

Set up the Oracle variables environment

# export ORACLE_SID=your-instance-name

# export ORACLE_HOME=your-oracle-home-directory

# export PATH=$PATH:$ORACLE_HOME/bin

Start the database listener and the database if there not up.

# lsnrctl start

# sqlplus “sys/your-password@your-service-name as sysdba”

SQL> startup

Check database version

# sqlplus “sys/your-password@your-service-name as sysdba”

SQL> select version from product_component_version

Where product like ‘Oracle%’

/

Check initialization parameters

# sqlplus “sys/your-password@your-service-name as sysdba”

SQL> select name, value from v$parameter;

Check required database option

SQL> select * from v$option; BIT-map indexes, Materialized view rewrite,

Materialized view warehouse refresh, OLAP Window Functions,

Parallel execution, Parallel Load, and Partitioning.

SQL> select count(*) from dba_objects

Where object_type like ‘JAVA%’ and owner = ‘SYS’ and status = ‘VALID’; -- result > 0 for java

SQL> select count (name) from sys.props$

Where name = ‘EXPORT_VIEWS_VERSION’; -- result > 0 for Intermedia

Check required PL/SQL packages

SQL> select count(object_name) from all_objects

Where object_name like ‘blow-package’ and status = ‘VALID’; -- result > 0 for following

DBMS_AQADM, DBMS_DDL, DBMS_LDAP, DBMS_LOCK,

DBMS_OBFUSCATION_TOOLKIT, DBMS_OUTPUT, DBMS_REPUTIL,

DBMS_SHARED_POOL, DBMS_SQL, DBMS_STATS, DBMS_UTILITY,

DBMS_FILE, DBMS_RAW

Check registration with Oracle Internet Directory

Note that the existing database is not already registered with any Oracle Internet Directory (OID).

If it is, then you may get unexpected problem during runtime.

To find if a database is already register, do the following:

# cd $ORACLE_HOME/bin

# ./dbca

If the database configuration assistant displays the directory service screen, which

enables you to de-register the database, then the database is already registered.

Make sure to de-register it.

Run OracleAS “RepCA” to install the Metadata Repository in an existing database

To run the Oracle Application Server Repository Creation Assistant (RepCA):

# runRepca –OH $ORACLE_HOME –LOGDIR $ORACLE_HOME/assistants/repca/log

Install OracleAS Infrastructure using the above existing metadata repository

# ./location-of-your-cd-rom/runInstaller -- after inserting the OracleAS

Define a new location and select infrastructure with Identity Management.

Select Oracle Internet Directory, OracleAS Single Sign-On,

Oracle Delegated Administration Services, Oracle Directory Integration and Provisioning.
