Some time ago I read a post about HTMLDB at Vidya Bala's Blog She has mentioned nice description about HTMLDB & Installing HTMLDB 2.0. You can check her post at Install HTMLDB 2.0
Now HTMLDB is called as Application Express or more commonly as Apex. Latest Apex Version is 2.2 and today I'll quickly cover Installation of Apex Version 2.2. You can find Installation Document and software at end of this post.
Requirement:
In order to install Apex (Former HTMLDB) ver 2.2 you should have
--Application Server Version 1.0.2.2 or higher
--Database should be version 9.2.0.3 or higher
--Disk Space around 500 MB on middle tier (Application Server)
--Tablespace (in which you will install Apex ) with around 100MB free space
--System tablespace with around 85 MB free space
--Database shared pool size should be 100MB or more
Tablespaces:
At time of Apex installation it asks for tablespace for user data & tablespace for Apex files. You can use existing single tablespace for both or can create these two tablespace. For better understanding I will create two tablespace one for User data & other for Apex files.
Assumptions
Below Apex 2.2 Installation steps are of Database version 10.2.X and application server version 10.1.2.0.2 (There might be minor changes on other database or application server version)
Pre Installation Configuration
Login to database and create two tablespace
create tablespace tsapexf datafile '/$datafile_location/tsapexf01.dbf' size 50M autoextend on next 10M maxsize 300M;
create tablespace tsapexu datafile '/$datafile_location/tsapexu01.dbf' size 50M autoextend on next 10M maxsize 300M;
These tablespaces we are going to use during Apex Installation
Loading Apex into Database
Login to middle tier(Application Server) & download Apex 2.2 software from location mentioned at end of this post (software is with name apex_2.2.zip);
Copy it to location where you want to install Apex on Middle tier ; assume its /u01/dev
unzip software as ; unzip apex_2.2.zip
This will craete a subdirectory with name apex ; cd apex
sqlplus system@tns_alias as sysdba (From middle tier connect to database as sysdba)
@apexins.sql {passwd} {ts for user} {ts for files} {ts for temp} /i/ {connect_info}
Where
passwd - Password for Apex Super User
ts for user - Tablespace for User data (Created above)
ts for files - Tablespace for Apex files (Created above)
ts for temp - temporary tablespace (Usually Temp)
i - is the alias for image directory configuration in Application Server (Apache httpd.conf)
connect info - TNS Alias to connect to database from middle Tier @apexins.sql mypasswd tsapexu tsapexf temp /i/ tns_alias This step will take 1-2 hours depending on server configuration
Configure Apex at Middle Tier (Application Server)
Create a file marvel.conf in $ORACLE_HOME/Apache/modplsql/conf
Replace ORACLE_HOME, hostname, port number, service_name, and apex_public_user_password with values appropriate for your environment.
######### Alias /i/ "/u01/dev/apex/images/"
AddType text/xml xbl
AddType text/x-component htc
Order deny,allow
PlsqlDocumentPath docs
AllowOverride None
PlsqlDocumentProcedure wwv_flow_file_manager.process_download
PlsqlDatabaseConnectString hostname.domainname:db_port:SID ServiceNameFormat
PlsqlNLSLanguage AMERICAN_AMERICA.AL32UTF8
PlsqlAuthenticationMode Basic
SetHandler pls_handler
PlsqlDocumentTablename wwv_flow_file_objects$
PlsqlDatabaseUsername APEX_PUBLIC_USER
PlsqlDefaultPage apex
PlsqlDatabasePassword password
Allow from all
####### include marvel.conf in httpd.conf like below so that it can be invoked each time Apache(Web Server) Starts
include "/replace_this_with_oracle_home/Apache/modplsql/conf/marvel.conf" Update this configuration change in DCM repository (This step is required only on 10g Application Server, Skip this if you are configuring it with Apps 11i or standalone HTTP Server)
Make sure Alias /i/ "/u01/dev/apex/images/" this alias in marvel.conf is pointing to right apex images directory
Post Installation Steps
dcmctl updateconfig -ct ohs
opmnctl restartproc ias-component=HTTP_Server (Restart HTTP Server to check it)
Now try access application via URL
http://hostname.domainname:port/pls/apex
