How
many different development topologies you may have?
1. Java developer topology
2. Departmental Topology
3. Development life-cycle
support topology
When
do you use the development topology?
We use the development
topology for the following scenario:
A website-based
application for purchasing products.
A website-based
application for any online processes.
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.
Answers all the questions:
Note that the Oracle port
assignments are in $ORACLE_HOME/<sid>/install/portlist.ini
