Some limitations apply to configurations using Oracle database software. If you configured an Oracle event database, keep the following considerations in mind:
The Oracle 10g JDBC thin driver imposes some size restrictions for string values if you are using a Unicode character set. This can result in an Oracle ORA-01461 error when events containing large values (such as a long message attribute) are stored in the event database. For more information about this restriction, refer to the Oracle 10g documentation.
To avoid this problem, use the Oracle 10g OCI driver or the Oracle 9i thin driver.
