Esse plano de ação deve exigir apenas uma reinicialização do clusterware versus correção, o que pode resultar em duas ou três reinicializações do clusterware.

Vamos ao procedimento.


1. Backup gpnp profile

[grid@testoda1 peer]$ cd /u01/app/18.0.0.0/grid/gpnp/'hostname'/profiles/peer
[grid@testoda1 peer]$ cp -p profile.xml profile.xml.bkp
[grid@testoda2 peer]$ /u01/app/18.0.0.0/grid/gpnp/'hostname'/profiles/peer
[grid@testoda2 peer]$ cp -p profile.xml profile.xml.bkp

2. Obtenha as interfaces cluster_interconnect (apenas no node 1)

[grid@testoda1 ~]$ /u01/app/18.0.0.0/grid/bin/oifcfg getif

btbond1 10.32.16.0 global public
p1p1 192.168.16.0 global cluster_interconnect,asm
p1p2 192.168.17.0 global cluster_interconnect,asm

Observe: que os nomes de interface privada podem ser diferentes, dependendo do modelo e / ou versão do ODA que foi usada para implantar a máquina etc.

No restante desta nota, estamos usando p1p1 / p1p2 como exemplo nas etapas abaixo.

3. Faça backup de arquivos ifcfg- <interface> existentes

[root@testoda1 ~]# cd /etc/sysconfig/network-scripts
[root@testoda1 network-scripts]# cp ifcfg-p1p1 backupifcfgFiles/ifcfg-p1p1.bak
[root@testoda1 network-scripts]# cp ifcfg-p1p2 backupifcfgFiles/ifcfg-p1p2.bak
[root@testoda2 ~]# cd /etc/sysconfig/network-scripts
[root@testoda2 network-scripts]# cp ifcfg-p1p1 backupifcfgFiles/ifcfg-p1p1.bak
[root@testoda2 network-scripts]# cp ifcfg-p1p2 backupifcfgFiles/ifcfg-p1p2.bak

4. Crie ifcfg-icbond0 e modifique os arquivos ifcfg- <interface>

[root@testoda1 network-scripts]# vi /etc/sysconfig/network-scripts/ifcfg-icbond0

[root@testoda2 network-scripts]# vi /etc/sysconfig/network-scripts/ifcfg-p1p2

5. Criando / substituindo init.ora-s para instâncias APX

[grid@testoda1]$ echo "+APX1.cluster_interconnects='192.168.16.24'" > $ORACLE_HOME/dbs/init+APX1.ora

[grid@testoda2]$ echo "+APX2.cluster_interconnects='192.168.16.25'" > $ORACLE_HOME/dbs/init+APX2.ora

6. Pare o Clusterware no node 2

[root@testoda2 ~]# /u01/app/18.0.0.0/grid/bin/crsctl stop crs -f

7. Defina a nova interface cluster_interconnect ligada e remova as interfaces p1p1 / p1p2 da configuração (apenas no node 1)

[grid@testoda1 ~]$ oifcfg setif -global icbond0/192.168.16.0:cluster_interconnect,asm

[grid@testoda1 ~]$ oifcfg getif

btbond1 10.209.244.0 global public
p1p1 192.168.16.0 global cluster_interconnect,asm
p1p2 192.168.17.0 global cluster_interconnect,asm
icbond0 192.168.16.0 global cluster_interconnect,asm

[grid@testoda1 ~]$ oifcfg delif -global p1p1/192.168.16.0

[grid@testoda1 ~]$ oifcfg delif -global p1p2/192.168.17.0

[grid@testoda1 ~]$ oifcfg getif

btbond1 10.209.244.0 global public
icbond0 192.168.16.0 global cluster_interconnect,asm

8. Remova a dependência do HAIP no ora.asm

[root@testoda1 ~]# /u01/app/18.0.0.0/grid/bin/crsctl modify res ora.cluster_interconnect.haip -attr ENABLED=0 -init

[root@testoda2 ~]# /u01/app/18.0.0.0/grid/bin/crsctl modify res ora.cluster_interconnect.haip -attr ENABLED=0 -init

[root@testoda1 ~]# /u01/app/18.0.0.0/grid/bin/crsctl modify res ora.asm -attr "START_DEPENDENCIES='hard(ora.cssd,ora.ctssd) pullup(ora.cssd,ora.ctssd) weak(ora.drivers.acfs)', STOP_DEPENDENCIES='hard(intermediate:ora.cssd)'" -init

[root@testoda2 ~]# /u01/app/18.0.0.0/grid/bin/crsctl modify res ora.asm -attr "START_DEPENDENCIES='hard(ora.cssd,ora.ctssd) pullup(ora.cssd,ora.ctssd) weak(ora.drivers.acfs)', STOP_DEPENDENCIES='hard(intermediate:ora.cssd)'" -init

9. Removendo o recurso ora.cluster_interconnect.haip

[root@testoda1 ~]# /u01/app/18.0.0.0/grid/bin/crsctl delete resource ora.cluster_interconnect.haip -init –f

[root@testoda2 ~]# /u01/app/18.0.0.0/grid/bin/crsctl delete resource ora.cluster_interconnect.haip -init –f

10. Pare o Clusterware no node1

[root@testoda1 ~]# /u01/app/18.0.0.0/grid/bin/crsctl stop crs -f

11. Reinicie a rede

[root@testoda1 network-scripts]# service network restart

[root@testoda1 network-scripts]# ifconfig -a

[root@testoda1 network-scripts]# cat /proc/net/bondinf/icbond0

[root@testoda2 network-scripts]# service network restart

[root@testoda2 network-scripts]# ifconfig -a

[root@testoda2 network-scripts]# cat /proc/net/bondinf/icbond0

12. Reinicie o Clusterware

[root@testoda1 ~]# /u01/app/18.0.0.0/grid/bin/crsctl start crs

[root@testoda2 ~]# /u01/app/18.0.0.0/grid/bin/crsctl start crs

13. Reinicie o dcs-agent para redescobrir as interfaces automaticamente

[grid@testoda1 ~]# /opt/oracle/dcs/bin/restartagent.sh

[grid@testoda2 ~]# /opt/oracle/dcs/bin/restartagent.sh

14. Verificando o serviço de cluster após remover o serviço

[root@testoda1 ~]#

[root@testoda1 ~]# /u01/app/18.0.0.0/grid/bin/crsctl check cluster -all
