11 Oracle Web Cache

This chapter describes issues associated with Oracle Web Cache. It includes the following topics:

11.1 Configuration Issues and Workarounds

This section describes configuration issues and their workarounds. It includes the following topics:

11.1.1 Reset the Random Password Generated When Installing Oracle Portal, Forms, Reports, and Discoverer

For enhanced security, no default hard-coded passwords are used for managing Oracle Web Cache.

When you install the Oracle Web Tier installation type, the Oracle Universal Installer prompts you to choose a password. The Web Cache Administrator page of the Oracle Universal Installer prompts you to enter a password for the administrator account. The administrator account is the Oracle Web Cache administrator authorized to log in to Oracle Web Cache Manager and make configuration changes through that interface.

When you install Oracle Portal, Forms, Reports, and Discoverer, the prompt for the administrator password is missing. Instead, the Oracle Portal, Forms, Reports and Discoverer install type uses a random value chosen at install time.

Regardless of the installation type, before you begin configuration, change the passwords for these accounts to a secure password. If you are configuring a cache cluster, all members of the cluster must use the same password for the administrator account.

To change the password, use the Passwords page of Fusion Middleware Control, as described in "Configuring Password Security" in the Oracle Fusion Middleware Administrator's Guide for Oracle Web Cache.

11.1.2 Running Oracle Web Cache Processes as a Different User Is Not Supported

Running Oracle Web Cache as a user other than the installed user through the use of the webcache_setuser.sh setidentity command is not supported.

Specifically, you cannot change the user ID with the following sequence:

  1. Change the process identity of the Oracle Web Cache processes in the Process Identity page using Oracle Web Cache Manager (Properties > Process Identity).

  2. Use the webcache_setuser.sh script as follows to change file and directory ownership:

    webcache_setuser.sh setidentity user_ID 
    

    user_ID is the user you specified in the User ID field of the Process Identity page.

  3. Restart Oracle Web Cache using opmnctl.

    Oracle Web Cache will start and then immediately shut down.

    In addition, messages similar to the following are displayed in the event log:
