MIB Definition

You can find the SNMP MIB file at the following location:

OMS_HOME/network/doc/omstrap.v1

Note:

The omstrap.v1 file is compatible with both SNMP V1 and SNMP V3.

The file omstrap.v1 is the OMS MIB.

For more information, see Interpreting Variables of the Enterprise Manager MIB.

A hardcopy version of omstrap.v1 can be found in Enterprise Manager MIB Definition.

The length of the SNMP OID value is limited to 2560 bytes by default. Configure emoms property oracle.sysman.core.notification.snmp.max_oid_length to change the default limit.

For Enterprise Manager 12c, SNMP traps are delivered for event notifications. Starting in Enterprise Manager 13.5 RU16, SNMP trap notifications are supported for both events and incidents. SNMP trap notifications are not supported for problems.

Note:

SNMP advanced notification methods defined using previous versions of Enterprise Manager (pre-12c) will continue to function without modification. Traps will conform to the older Enterprise Manager MIB definition.
