Item Description

7.Install and configure the KDC. When you install the KDC, ensure that you have this information available:

•A valid license for KDC.

•KDC realm—Identified by a unique name, the KDC realm consists of a KDC, and the clients and servers registered to that KDC.

Note The realm must match the certificate chain at the KDC.

•KDC FQDN—This is the fully qualified domain name on which the KDC server is located.

•KDC interface address—This is the interface (generally the IP address of the KDC server) on which the KDC listens for requests.

Note During installation it may be necessary to install several Solaris patches on your computer. The installation program will display a complete list of patches that are required. Should patch installation become necessary, refer to the Sun Microsystems website to download the required patches.

Note If you decide to terminate the BACC installation after the operating system database has been installed, you must uninstall it before attempting to reinstall the product. If you do not do this, and rerun the installation program, you cannot change the location of either the <BACC_DATA> and <BACC_DBLOG> directories.

Broadband Access Center Database Requirements

Before you install BACC, be aware of these database considerations:

•File system block size

•Support for large files

For optimum performance and reliability of the BACC database, configure the file system or systems that contain the database files and database log files with an 8 KB block size or greater. If your system configuration does not support an 8 KB block size, then configure the block size in multiples of 8 KB; for example, 16 KB or 32 KB.

The installation program prompts you to specify a directory in which to install database files and database log files. These directories are identified in BACC with system variables, <BACC_DATA> and <BACC_DBLOG> respectively.

To verify that a directory resides on a file system with a minimum 8 KB block size, follow these steps:

Step 1 Run the UNIX mount command without any parameters to determine on which file system device the directory resides. The default directory is /var/CSCObpr. For example:

/var on /dev/dsk/c0t0d0s4 read/write/setuid/intr/largefiles/onerror=panic/dev=2200004 on Mon Nov 26 08:07:53

In this example, the file system device is /dev/dsk/c0t0d0s4.
