Configuring VERITAS Storage Foundation

Once you install and initialize all of the VERITAS software, you can take advantage of the various storage management features to ease the task of system and database administration.

Database Configuration Requirements

Most relational database management system (RDBMS) software requires operating system parameters to be set prior to operation. The Oracle database requires modifications to kernel settings before the databases will run correctly. The most critical settings are normally located in the Shared Memory and Semaphore settings on HP-UX. For precise settings, consult your current database installation and configuration documentation.

Setting Administrative Permissions

To allow database administrators to administer a database using VERITAS Storage Foundation, you are required to change some permission settings. During the installation process, you have the opportunity to configure the product. Answering "y" allows you to provide database administrators access to various functionality. If you did not make the permission changes during installation, you can do so at a later time.

The default settings at installation time for the /opt/VRTSdbed directory allow only the root login to access the directory.

  To allow the user "oracle" access to the /opt/VRTSdbed directory

  To allow users in the group "dba" access to the /opt/VRTSdbed directory

vxtunefs Command Permissions and Cached Quick I/O

By default, you must have superuser (root) privileges to use the /opt/VRTS/bin/vxtunefs command. The vxtunefs command is a tool that lets you change caching policies to enable Cached Quick I/O and change other file system options. Database administrators can be granted permission to change default file system behavior in order to enable and disable Cached Quick I/O. The system administrator must change the vxtunefs executable permissions as follows:
