With this PTF, the counters for Cache Hit Bytes Served and the Cache Missed Bytes Served have been expanded from 32 bits to 64 bits. In Talk 5, each of these 64-bit counters will be displayed in decimal as two 32-bit values.

You can also use SNMP to access each 64-bit hit and miss counters. The high order 32 bits of each counter have been added at the end of an OID tree structure as follows:
1.3.6.1.4.1.2.6.119.4.8.2.1.1.x.y where y = cache partition number and x = 54 for ibmcacheserverPartitionHitByteCount 55 for ibmcacheserverPartitionMissByteCount 56 for ibmcacheserverPartitionHitByteCountHi 57 for ibmcacheserverPartitionMissByteCountHi
The following TCP-related parameters are also added to the Web Server Cache MIB:
1.3.6.1.4.1.2.6.119.4.8.1.x where x = 4 for webcacheCoreTCPcurconn (current count of TCP connections) 5 for webcacheCoreTCPmaxconn (maximum count of TCP connections) 6 for webcacheCoreSOcurconn (current count of SOX connections) 7 for webcacheCoreSOmaxconn (maximum count of SOX connections)
Additionally, by using the Talk 6 patch command, you can disable ECCM authentication (enabled is the default). To disable ECCM authentication, use the patch command to change the variable ecc-auth-disable to any non-zero value as follows:
Config>patch Variable to patch ?[] ecc-auth-disable New Value [0]? 1 Variable patched successfully Config>
To re-enable ECCM authentication, use the patch command to change the variable back to zero:
Config>patch Variable to patch ?[] ecc-auth-disable New Value [1]? 0 Variable patched successfully Config>
