When running dbca to create a new database you can get the following message:

Default Listener “LISTENER” is not configured in Grid Infrastructure home. Use NetCA to configure Default Listener and rerun DBCA

Actually, there’s no need to run netca, all you need is to create a new listener as follows:

srvctl add listener

srvctl start listener

While installing Oracle Database after Oracle Grid Infrastructure installation, I was supposed to get the list of all nodes where I need to install Oracle Software (11gR2 – 11.2.0.4). But instead, I got nothing

I checked the status of the clusterware, it was up and running on both nodes:

[oracle@node1 bin]$ ./olsnodes
node1
node2
[oracle@node1 bin]$ ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

Then I checked the inventor.xml file and found out that the CRS=true is missing.

[oracle@node1 bin]$ cat /etc/oraInst.loc | grep inventory_loc
inventory_loc=/u01/app/oraInventory

[oracle@node1 bin] cd /u01/app/oraInventory/ContentsXML/

[oracle@node1 bin] more inventory.xml

<output trimmed ————— >

<HOME NAME=”Ora11g_gridinfrahome1″ LOC=”/u01/app/product/11.2.0.3/grid” TYPE=”O” IDX=”1″>

</output trimmed ————->

After running the following command, I updated the inventory.xml file and node list appeared

[oracle@node1 ~]$ cd /u01/app/product/11.2.0.3/grid/oui/bin/
[oracle@node1 bin]$ ./runInstaller -updateNodeList ORACLE_HOME=”/u01/app/product/11.2.0.3/grid” CRS=true
