Sfaturi Oracle / Tips and tricks OracleDBA: 11gR2 Grid Infrastructure Redundant Interconnect

11gR2 Grid Infrastructure Redundant Interconnect and ora.cluster_interconnect.haip [ID 1210883.1]

11gR2 Grid Infrastructure Redundant Interconnect and ora.cluster_interconnect.haip

Redundant Interconnect without any 3rd-party IP failover technology (bond, IPMP or similar) is supported natively by Grid Infrastructure starting from 11.2.0.2. Multiple private network adapters can be defined either during the installation phase or afterward using the oifcfg. Oracle Database, CSS, OCR, CRS, CTSS, and EVM components in 11.2.0.2 employ it automatically.

Grid Infrastructure can activate a maximum of four private network adapters at a time even if more are defined. The ora.cluster_interconnect.haip resource will start one to four link local HAIP on private network adapters for interconnect communication for Oracle RAC, Oracle ASM, and Oracle ACFS etc.

Grid automatically picks link local addresses from reserved 169.254.*.* subnet for HAIP, and it will not attempt to use any 169.254.*.* address if it's already in use for another purpose. With HAIP, by default, interconnect traffic will be load balanced across all active interconnect interfaces, and corresponding HAIP address will be failed over transparently to other adapters if one fails or becomes non-communicative. .

The number of HAIP addresses is decided by how many private network adapters are active when Grid comes up on the first node in the cluster . If there's only one active private network, Grid will create one; if two, Grid will create two; and if more than two, Grid will create four HAIPs. The number of HAIPs won't change even if more private network adapters are activated later, a restart of clusterware on all nodes is required for new adapters to become effective.

When Oracle Clusterware is fully up, resource haip should show status of ONLINE:

$ $GRID_HOME/bin/crsctl stat res -t -init
..
ora.cluster_interconnect.haip
1 ONLINE ONLINE racnode1

Case 1: Single Private Network Adapter

If multiple physical network adapters are bonded together at the OS level and presented as a single device name, for example bond0, it's still considered a single network adapter environment. If only one private network adapter is defined, such as eth1 in the example below, one virtual IP will be created by HAIP. Here is what's expected when Grid is up and running:

$ $GRID_HOME/bin/oifcfg getif
eth1 10.1.0.128 global cluster_interconnect
eth3 10.1.0.0 global public

$ $GRID_HOME/bin/oifcfg iflist -p -n
eth1 10.1.0.128 PRIVATE 255.255.255.128
eth1 169.254.0.0 UNKNOWN 255.255.0.0
eth3 10.1.0.0 PRIVATE 255.255.255.128

Note: subnet 169.254.0.0 on eth1 is started by resource haip.

Note: interconnect will use virtual private IP 169.254.167.163 instead of real private IP. For pre-11.2.0.2 instance, by default it will still use the real private IP; to take advantage of the new feature, init.ora parameter cluster_interconnects can be updated each time Grid is restarted .

For 11.2.0.2 and above, v$cluster_interconnects will show haip info:

Note: interconnect communication will use all four virtual private IPs; in case of network failure, as long as there is one private network adapter functioning, all four IPs will remain active.

Known Issues

Bug 10370797

Issue: HAIP fails to start on AIX

Fixed in: 11.2.0.3, interim patch 10370797 exists for 11.2.0.2, affects AIX only

Symptom:

Output of root script:

CRS-2672: Attempting to start 'ora.cluster_interconnect.haip' on 'racnode1'
CRS-5017: The resource action "ora.cluster_interconnect.haip start" encountered the following error:

CRS-5017: The resource action "ora.cluster_interconnect.haip start"

2010-12-12 09:41:40.201: [ CLSINET][1088543040] Returning NETDATA: 0 interfaces

Solution:

The cause is mismatch of private network information in OCR and on OS, output of the following should be consistent with each other (network adapter name, subnet and netmask):

oifcfg iflist -p -n oifcfg getif ifconfig

Bug 10363902

Issue: HAIP fails to start if cluster interconnect is on Infiniband or any other network hardware type that has hardware address (MAC) longer than 6 bytes

Bug 10397652

Issue: HAIP does not failover even when private network experiences problem (i.e. switch port disabled or such) as OS is not providing reliable link information

Fixed in: 11.2.0.3

Workaround on AIX is to set "MONITOR" flag for all private network adapters

# ifconfig en1 monitor # ifconfig en1 en1: flags=5e080863,2c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST, GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN,MONITOR> inet 192.168.10.83 netmask 0xfffffc00 broadcast 192.168.11.255 inet 169.254.74.136 netmask 0xffff8000 broadcast 169.254.127.255 tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0
