Today, I would like to talk to you about how to analyze ins-40937 errors, many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

The following error occurred when installing oracle12C on windows2012 Enterprise server:

Solution:

Reason

The binding order of the network adapter on the node that returned the error is invalid.

One of the prerequisites for installing grid infrastructure on the Windows platform is

List the "public" network adapter first in the binding order, and then

On all cluster nodes, your "dedicated" network adapter is listed second in binding order.

Solution

Fix the network adapter binding order so that the public network adapters are listed first, and then

According to the recorded installation prerequisites, your private network adapter is listed in the second place

Add:

Other possible problems:

1. Make sure that vip and public ip are in the same network segment

Ip Planning:

11.114.72.83 public-rac1

11.114.72.84 rac1-vip

192.168.0.1 rac1-priv

11.114.72.85 public-rac2

11.114.72.86 rac2-vip

192.168.0.2 rac2-priv

11.114.72.100 scan

Similar problems will occur if vip and public Ip are not in the same network segment.

2. The hosts configuration of both nodes should be the same.

And ping pub1, vip1 and pub2,vip2 should be able to communicate with ping.

3. Special symbols. There seems to be no problem with the / etc/hosts configuration, but it will also report an error ins-40937 following host names are not valid. In fact, it is found that the underscore in the hosts configuration will lead to an error, and the downline in this hosts configuration does not comply with the RFC 952 rules.

Bug 3396924:'_ 'UNDERSCORE CHARACTER ALLOWED DURING INSTALL PROCESS BUT ILLEGAL IN DNS RFC

Official file notes

Note:

All host names must conform. To the RFC 952 standard, which permits alphanumeric characters. Host names using underscores ("_") are not enabled.

4. Another situation is to pay attention to the order of network cards in a virtualized environment, with public in the front and private in the back, and the two ends are the same.

Add:

PS C:\ orainstallerfile\ winx64_12102_grid_union\ grid >. / setup.exe-ignorePrereq-J "- Doracle.install.client.validate.clientSupportedOSCheck=false"

Skip grid error

PS C:\ orainstallerfile\ winx64_12102_grid_union\ grid >. / setup.exe-ignorePrereq-J "- Doracle.install.db.validate.supportedOSCheck=false"

Skip db error
