kernelMaxCOMMessageSize
Module: BEA-WEBLOGIC-MIB
OID (symbolic): BEA-WEBLOGIC-MIB::kernelMaxCOMMessageSize
OID (numeric): 1.3.6.1.4.1.140.625.692.1.75
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Specify the maximum COM message size allowable in a message header. This attribute attempts to prevent a denial of service attack whereby a caller attempts to force the server to allocate more memory than is available thereby keeping the server from responding quickly to other requests.
What is kernelMaxCOMMessageSize?
This OID limits the maximum COM message size in the header to prevent memory exhaustion attacks. Example: setting this to 10485760 (10MB) rejects COM messages claiming to be larger.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.140.625.692.1.75 snmpwalk -v2c -c public <target> BEA-WEBLOGIC-MIB::kernelMaxCOMMessageSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.140.625.692.1.75.1 snmpget -v2c -c public <target> BEA-WEBLOGIC-MIB::kernelMaxCOMMessageSize.1
