Installation • APEX is included with 10g database. • For 9.2 and above, download apex_2.2.1.zip from Oracle Technology Network. Follow instructions for install. – Call coreins.sql from sqlplus to install all database objects (~20 minutes). – Copy images directory into $IAS_ORACLE_HOME/Apache – Add a new DAD entry to $IAS_ORACLE_HOME/Apache/modplsql/cfg/wdbsvr.app – Add new alias and types to $IAS_ORACLE_HOME/Apache/Apache/conf/httpd.conf

Installation Tips • Dad entry in wdbsvr.app: # Begin customizations [DAD_apex] connect_string = hostname:db_port:SID password = apex username = apex_public_user default_page = apex document_table = wwv_flow_file_objects$ document_path = docs document_proc = wwv_flow_file_mgr.process_download reuse = Yes enablesso = No stateful = STATELESS_RESET nls_lang = American_America.US7ASCII custom_auth = Basic # End customizations

• Connect to http://hostname/pls/apex

Installation Tips • If you receive the error ‘Authorization Required’ at login: – Comment out the custom_auth=CUSTOM variable in wdbsvr.app OR – Confirm that DAD_APEX includes custom_auth = Basic in wdbsvr.app

• Add the following to the httpd.conf file: # Begin customizations Alias /i/ "/fiprdafs/fiprd1ora/iAS/Apache/images/" AddType text/xml xbl AddType text/x-component htc # End customizations

– The Alias points to the APEX images directory you must copy into your $IAS_ORACLE_HOME/Apache path – The AddType allows you to edit sql scripts with APEX inside the browser

Best Practices for integrating APEX • Create a custom E-Business Suite application (separate schema) – Tables, Views, Sequences and Triggers go into custom schema – Grants, Synonyms, and PL/SQL go into APPS schema

• Setup APEX workspace to parse the APPS schema so that APEX can see all the EBS objects

Integration with E-Business Suite • You may wish to rapidly develop forms and reports on request. We have developed APEX applications for the following: – – – –
