How to solve the problem of debug VIP fault and its treatment because the gateway is missing, the VIP resource cannot be started

How to troubleshoot debug VIP problems:

-----View statistics for node application resources:

/u01/crs/bin/srvctl config nodeapps-n dbtest2-a-g-s-L

VIP exists.:/dbtest2-vip/10.11.11.198/255.255.255.0/eri0

GSD exists.

ONS Daemon exists.

Listener does not exist.

------Debug VIP

Further debug it by uncommenting the environment variable _usr_ora_debug=1 in the script $ORA _CRS_HOME/BIN/RACGVIP

OR simply as root user, issue the command:

Crsctl Debug Log res "Ora.dbtest2.vip:5"

Turn off debugging with command:

Crsctl Debug Log res "ora.dbtest2.vip:0"

Start the VIP using Srvctl start Nodeapps again. This would create a log for VIPs starting problem for 10.2 and above version

In Directory $ORA _crs_home/log/<nodename>/racg/*vip.log

----------the role of Gateway gateways in Oracle RAC 10g:

By default, the server's default gateway is used as a ping target during the Oracle RAC 10g VIP status check action.

See more highlights of this column: http://www.bianceng.cnhttp://www.bianceng.cn/database/storage/

Upon a ping failure, Oracle would decide that this current interface where the VIP is running has, and would failed An Interface/internode VIP failover.

In above case, we used just one node for CRS installation, so the VIP coudn ' t failover to other nodes and thus ad Ditional error like:

Crs-1006:no to consider

Crs-0215:could Not start resource ' ORA.DBTEST2.VIP '.

--------SOLUTION

10.1.0.4 and above introduced a parameter Fail_when_defaultgw_not_found in the file

$ORA _CRS_HOME/BIN/RACVIP to address this problem.

The following steps would fix the VIP starting problem for above mentioned.

1-stop Nodeapps

2-as Root,

VI the script $ORA _CRS_HOME/BIN/RACGVIP and change the value of

Variable fail_when_defaultgw_not_found=0.

3-start Nodeapps and you should to the resources ONLINE

You could proceed with NETCA and DBCA to create a RAC database after this.

Add default gateway
