Most relational database management system (RDBMS) software requires operating system parameters to be set prior to operation. The DB2, Oracle, and Sybase databases require modifications to kernel settings in the /etc/system file in Solaris 9 before the databases will run correctly. In Solaris 10, system parameters are managed through the Resource Controls facility.The most critical settings are normally located in the Shared Memory and Semaphore settings on Solaris. For precise settings, consult your current database installation and configuration documentation.
