The first step is to review the logs created by the DBCA to determine whether there are additional errors that may assist with troubleshooting this problem. The DBCA logs can be found in $ORACLE_HOME/assistants/dbca/logs.
You can also create the instance manually via SQL*Plus to determine whether you receive the same errors. If you encounter the same errors when you attempt to create a database both through the DBCA and manually, this may point to an operating system resource issue. Review the required kernel parameters for Oracle 9.2 on Solaris to ensure that the settings are sufficient for creating a database. This information can be found on Oracle's Technology Network Web site.
