This chapter describes how you can set up and use mod_plsql. It contains the following sections:
Before you run mod_plsql, you must satisfy the following requirements:
You must have a SYS user password on the database where you plan to load PL/SQL Web Toolkit packages required by mod_plsql.
The database to which you plan to connect mod_plsql must be up and running.
Oracle HTTP Server mod_plsql ships with OWA package version 126.96.36.199.1. It is recommended that the OWA packages installed in the database are at least version 188.8.131.52.1.
After installation, if you need to use Oracle HTTP Server mod_plsql with a database that is not shipped with the product, you must manually install additional required packages using the
Note:Even if a full database export is made with the Export utility you still must reinstall mod_plsql in the new target instance by running the
OWALOAD.SQLscript as SYS. Objects in SYS are not imported with the Import/Export mechanism, and the PL/SQL toolkit has to be installed in SYS.
Navigate to the directory where the
owaload.sql file is located. This directory is
Using SQL*Plus, login to the Oracle database as the SYS user.
You can check the version of the OWA packages currently installed by running the following query:
select owa_util.get_version from dual;
If the query succeeds, but shows a version less than 184.108.40.206.1, it is recommended that you install the newer OWA packages.
If the query fails, you either do not have the OWA packages installed, or are running a very old version of OWA packages, and it is recommended that you install, or upgrade to the new OWA packages.
Note:To detect older OWA packages, see "How do I detect and clean up duplicate OWA packages installed in the database?" in Appendix A, "Frequently Asked Questions".
At an SQL prompt, run the following command:
Installs the PL/SQL Web Toolkit packages into the SYS schema. It also creates public synonyms and makes the packages public so that all users in the database have access to them. Therefore, only one installation for each database is needed.
The installation log file. Make sure that you have write permissions to create the log file
Scan the log file for any errors.
owaloadscript checks the existing version of the OWA packages in the database and installs a new version only if:
No OWA package exists or,
Older OWA packages were detected. If your database already has the latest OWA packages or has a newer version installed, the
owaload script does nothing and reports this in the log file.
Do a manual recompile.
Note:Installing the OWA packages invalidates all dependent objects. These packages automatically recompile on first access, but a manual recompile is recommended after the reinstallation.
After the install, check the version of the OWA packages by running "
Select owa_util.get_version from dual;". Confirm that the version shown is 220.127.116.11.1 or later.
Note that public access is now granted to:
Note also that the following public synonyms are created:
OWA_CUSTOM for OWA_CUSTOM
OWA_GLOBAL for OWA_CUSTOM
OWA for OWA
HTF for HTF
HTP for HTP
OWA_COOKIE for OWA_COOKIE
OWA_IMAGE for OWA_IMAGE
OWA_OPT_LOCK for OWA_OPT_LOCK
OWA_PATTERN for OWA_PATTERN
OWA_SEC for OWA_SEC
OWA_TEXT for OWA_TEXT
OWA_UTIL for OWA_UTIL
OWA_INIT for OWA_CUSTOM
OWA_CACHE for OWA_CACHE
WPG_DOCLOAD for WPG_DOCLOAD
To access a Web-enabled PL/SQL application, you must first configure a PL/SQL Database Access Descriptor (DAD) for mod_plsql. A DAD is a set of values that specifies how mod_plsql connects to a database server to fulfill an HTTP request. Besides the connection details, a DAD contains important configuration parameters for various operations in the database, and for mod_plsql in general. For detailed instructions, refer to the mod_plsql section in the Oracle HTTP Server Administrator's Guide.
