Overview
Installation of Oracle Application Express in Oracle Database 11g has become much easier. In Oracle Database 11g, Oracle Application Express is installed when the database is installed. All you need to do is configure the PL/SQL gateway. In prior releases of the Oracle Database, you needed to install Apache, which is no longer needed although you can still use that option in Oracle Database 11g.
In order to take advantage of PDF reporting in Application Express, you can use BI Publisher. In this tutorial, you will install BI Publisher, configure Application Express to use the BI Publisher as its print server and run a PDF report in Application Express.
Prerequisites
Before you perform this tutorial, you should:
1. | Install Oracle Database 11g with the Advanced Installation. Note that if you install the database with the basic installation, you will not get all the necessary files to perform the Installing and Testing Translation Versions of Application Express section of this tutorial. | |
2. | Download and unzip the apexinst.zip file into your working directory which contains the files needed to perform this tutorial. |
Configuring the Embedded PL/SQL Gateway
In Oracle Database 11g, you configure the embedded PL/SQL gateway by running the configuration script apxconf.sql. Running this script enables you to configure the port for the Oracle XML DB HTTP server and to specify a password for the Oracle Application Express ADMIN account. Then you unlock the ANONYMOUS account. Perform the following steps:
1. | From your terminal window, enter the following command: Enter oracle when prompted for the ADMIN password. Press enter (to use the 8080 default) when prompted for the port for the XDB HTTP Listener. |
2. | You also need to unlock the anonymous user. From your terminal window, enter the following command: |
2. | To can now verify the port number where the Oracle XML DB HTTP Server is running. From your terminal window, enter the following command: |
Enabling Network Services
By default, the ability to interact with network services is disabled in Oracle Database 11g release 2 (11.2). Therefore, if you are running Oracle Application Express with Oracle Database 11g release 2 (11.2), you must use the new DBMS_NETWORK_ACL_ADMIN package to grant connect privileges to any host for the APEX_030200 database user. Failing to grant these privileges results in issues with:
- Sending outbound mail in Oracle Application Express.
- Using Web services in Oracle Application Express.
- PDF/report printing.
- Searching for content in online Help (that is, using the Find link).
Perform the following steps:
1. | You now need to provide less privileged access to local network resources. This will enable indexing the Oracle Application Express Online Help and will enable email and PDF printing when the server is also on the local host. From your terminal window, enter the following command: The script change_priv.sql is as follows: |
Installing BI Publisher
Oracle Business Intelligence Publisher (BI Publisher, formerly XML Publisher) is an enterprise reporting solution to author, manage, and deliver all types of highly formatted documents. In Application Express 3.0 and later, you can use BI Publisher as your print server to deliver PDF reports within Application Express. In order to utilize the capabilities of BI Publisher, it needs to be installed and configured within Application Express. Perform the following steps to install BI Publisher:
1. | From your browser window, enter the following URL: Accept the license and download the file corresponding to the environment you want to install. |
2. | Unzip the file and depending on what environment you are in, start the installer. In this case, you execute the following command on linux. |
3. | When the Welcome window appears, click Next. |
4. | Enter BIPHome1 for Name and /u01/app/oracle/product/bipub for Path and click Next. |
5. | Accept the default Installation Type of Basic and click Next. |
6. | Enter welcome1 for oc4jadmin Password and Confirm Password and click Next. |
7. | At the Summary window click Install. |
8. | The progress window appears. |
9. | The configuration assistant will run. |
10. | The installation completed successfully. Click Exit. |
11. | Click Yes to confirm. Note that after the installation is complete, a window is displayed where BI Publisher OC4J is running. Do not close this window. BI Publisher OC4J must be running to be able to successfully generate a PDF report in Application Express. |
Configuring BI Publisher in Application Express Administration
Before you can create a PDF Report using BI Publisher, you need to configure Application Express to use BI Publisher. Perform the following steps:
1. | Open your browser and enter the following URL: Enter admin as the username and enter your password oracle (or whatever password you specified during the installation). Then click Login. |
2. | The first time you login, you need to change your password. Enter your current password oracle and then enter the new password (in the VM Template provided, the password is Oracle_1) and click Apply Changes. |
3. | Click Return. |
4. | You need to login again and specify your new password. Then click Login. |
5. | Select the arrow next to Manage Services, select the arrow next to Manage Envrionment Settings and select Instance Settings. |
6. | Select the Report Printing tab. |
7. | Make sure the following are specified and click Apply Changes. Print Server: Advanced Print Server Protocol: HTTP Print Server Host Address: localhost Print Server Port: 9704 Print Server Script: /xmlpserver/convert Application Express has been configured to use BI Publisher. In the next section, you create a workspace. |
Creating a New Workspace and Workspace Administrator User
Before you create an application, you need to create a workspace and a workspace administrator user. Perform the following steps:
1. | Select the Manage Workspaces tab. |
2. | Under Manage Workspaces, select Create Workspace. |
3. | Enter obe as the Workspace Name and click Next. |
4. | For 'Re-use Existing Schema?' select No. Enter obe in the Schema Name and Password fields, and select 5 for the Space Quota. Then click Next. |
5. | Enter obe as the Administrator Username, and enter your Administrator Password and your e-mail address. Then click Next. Note: A new administrator user will be created in addition to the workspace. |
6. | Review your workspace request, and then click Create. |
7. | Your workspace and user are now created. Click Done. |
8. | You now want to log in as the obe user for the obe workspace. Click Logout. |
Testing BI Publisher Report Creation
At this point you can test the BI Publisher configuration by creating a PDF report. Perform the following steps:
1. | Click Login. |
2. | Enter the following details, and click Login. Workspace: obe Username: obe Password: <your password> |
3. | Click Application Builder. |
4. | Click Sample Application. |
5. | Select Details from the View pulldown and click Go. |
6. | Scroll down to the bottom of the page and select the Print link. |
6. | Open the file in a viewer (i.e. Adobe Reader) and click OK. |
7. | Your PDF report is shown successfully. Note: If your report does not appear, check to make sure that BI Publisher OC4J is started. Here is the command to start it: |
Installing Translation Versions of Application Express
If you want to be able to display your Application Express Application in different languages, you need to install the translated version for the language you want to translate to. For demonstration purposes, you will install and test the translation of the German language. Perform the following steps:
1. | From your terminal window, execute the following commands: |
2. | In your browser you need to add the German Language. Select Edit > Preferences. |
2. | Select the Advanced tab and under the General tab, click Edit Languages. |
3. | Select German (de) from the drop down list box and click Add. |
4. | Make sure German is selected and click Move Up until German appears first in the list. |
5. | Click OK. |

ADD_PRIVILEGE Procedure
Note:
This procedure is deprecated in Oracle Database 12c. While the procedure remains available in the package for reasons of backward compatibility, Oracle recommends using the APPEND_HOST_ACE Procedure and the APPEND_WALLET_ACE Procedure.This procedure adds a privilege to grant or deny the network access to the user. The access control entry (ACE) is created if it does not exist.
Parameters
Table 101-4 ADD_PRIVILEGE Function Parameters
Parameter | Description |
---|---|
acl | Name of the ACL. Relative path will be relative to '/sys/acls' |
principal | Principal (database user or role) to whom the privilege is granted or denied. Case sensitive. |
is_grant | Privilege is granted or denied. |
privilege | Network privilege to be granted or denied |
position | Position (1-based) of the ACE. If a non- NULL value is given, the privilege will be added in a new ACE at the given position and there should not be another ACE for the principal with the same is_grant (grant or deny). If a NULL value is given, the privilege will be added to the ACE matching the principal and the is_grant if one exists, or to the end of the ACL if the matching ACE does not exist. |
start_date | Start date of the access control entry (ACE). When specified, the ACE will be valid only on and after the specified date. The start_date will be ignored if the privilege is added to an existing ACE. |
end_date | End date of the access control entry (ACE). When specified, the ACE expires after the specified date. The end_date must be greater than or equal to the start_date . The end_date will be ignored if the privilege is added to an existing ACE. |
Usage Notes
To remove the permission, use the DELETE_PRIVILEGE Procedure.
APPEND_HOST_ACE Procedure
This procedure appends an access control entry (ACE) to the access control list (ACL) of a network host. The ACL controls access to the given host from the database and the ACE specifies the privileges granted to or denied from the specified principal.
Parameters
Table 101-5 APPEND_HOST_ACE Function Parameters
Parameter | Description |
---|---|
host | The host, which can be the name or the IP address of the host. You can use a wildcard to specify a domain or a IP subnet. The host or domain name is case-insensitive. |

Usage Notes
- Duplicate privileges in the matching ACE in the host ACL will be skipped.
- To remove the ACE, use the REMOVE_HOST_ACE Procedure.
- A host's ACL takes precedence over its domains' ACLs. For a given host, say
www.us.example.com
, the following domains are listed in decreasing precedence:www.us.example.com
*.us.example.com
*.example.com
*.com
*
- An IP address' ACL takes precedence over its subnets' ACLs. For a given IP address, say
192.168.0.100
, the following subnets are listed in decreasing precedence:192.168.0.100
192.168.0.*
192.168.*
192.*
*
- An ACE with a 'resolve' privilege can be appended only to a host's ACL without a port range.
- When ACEs with 'connect' privileges are appended to a host's ACLs with and without a port range, the one appended to the host with a port range takes precedence.
- When specifying a TCP port range of a host, it cannot overlap with other existing port ranges of the host.
- If the ACL is shared with another host or wallet, a copy of the ACL will be made before the ACL is modified.

- To remove the ACE, use REMOVE_WALLET_ACE.
- If the ACL is shared with another host or wallet, a copy of the ACL is made before the ACL is modified.
ASSIGN_ACL Procedure
Note:
This procedure is deprecated in Oracle Database 12c. While the procedure remains available in the package for reasons of backward compatibility, Oracle recommends using the APPEND_HOST_ACE Procedure and the APPEND_WALLET_ACE Procedure.This procedure assigns an access control list (ACL) to a host computer, domain, or IP subnet, and if specified, the TCP port range.
Parameters
Table 101-9 ASSIGN_ACL Function Parameters
Parameter | Description |
---|---|
acl | Name of the ACL. Relative path will be relative to ' /sys/acls '. |
host | Host to which the ACL is to be assigned. The host can be the name or the IP address of the host. A wildcard can be used to specify a domain or a IP subnet. The host or domain name is case-insensitive. |
lower_port | Lower bound of a TCP port range if not NULL |
upper_port | Upper bound of a TCP port range. If NULL , lower_port is assumed. |
Usage Notes
- Only one ACL can be assigned to any host computer, domain, or IP subnet, and if specified, the TCP port range. When you assign a new access control list to a network target, Oracle Database unassigns the previous access control list that was assigned to the same target. However, Oracle Database does not drop the access control list. You can drop the access control list by using the DROP_ACL Procedure. To remove an access control list assignment, use the UNASSIGN_ACL Procedure.
- The ACL assigned to a domain takes a lower precedence than the other ACLs assigned sub-domains, which take a lower precedence than the ACLs assigned to the individual hosts. So for a given host, for example, 'www.us.example.com', the following domains are listed in decreasing precedences:- www.us.example.com- *.us.example.com- *.example.com- *.com- *In the same way, the ACL assigned to an subnet takes a lower precedence than the other ACLs assigned smaller subnets, which take a lower precedence than the ACLs assigned to the individual IP addresses. So for a given IP address, for example, '192.168.0.100', the following subnets are listed in decreasing precedences:Vray for 3d max 2017 free download. - 192.168.0.100- 192.168.0.*- 192.168.*- 192.*- *
- The port range is applicable only to the 'connect' privilege assignments in the ACL. The 'resolve' privilege assignments in an ACL have effects only when the ACL is assigned to a host without a port range.For the 'connect' privilege assignments, an ACL assigned to the host without a port range takes a lower precedence than other ACLs assigned to the same host with a port range.
- When specifying a TCP port range, both
lower_port
andupper_port
must not beNULL
andupper_port
must be greater than or equal tolower_port
. The port range must not overlap with any other port ranges for the same host assigned already. - To remove the assignment, use UNASSIGN_ACL Procedure.
