Total disconnection of oracle11g monitoring network card (1)

Host: HP-UX essaop1 B.11.31 U ia64 1945507590 unlimited-user license

Database: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0-64bit Production

The host database of the system listens to the server and will restart automatically after starting or stopping for less than 5 minutes. Business is briefly affected.

There will be three lan900,lan901,lan902 virtual network cards aggregated through LAN_MONITOR for both xx.xx.89.1 and xx.xx.89.3 system lan cards, of which lan900 is the Infiniband type, lan901 and lan902 are the NIC type, and the three virtual network cards in the two systems are currently running normally, only the physical network card lan2 of the members of the lan902 is somewhat abnormal, the electrical performance and physical connection status of lan2 are normal, but the aggregation state is abnormal.

It is recommended that you first ask the network engineer to check the port status corresponding to the switch. Here is the MAC address of lan2 on both systems:

Node one:

Lan2 MAC:0x002481771834

Node 2:

Lan2 MAC:0x002481771868

Restart the APA-related services when all three virtual network cards can be interrupted:

/ sbin/init.d/hplm stop

/ sbin/init.d/hpapa stop

/ sbin/init.d/hpapa start

/ sbin/init.d/hplm start

After restarting the relevant APA service, it was suspended for three months, and the monitoring was no longer restarted. After that, there will be a second blog.
