Broadband Access Center Database Requirements
Broadband Access Center Database Requirements
Before you install BACC, be aware of these database considerations:
• File system block size
• Support for large files
File System Block Size
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.
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.
