Basic Steps for wenlogic dual-host Cluster

The following describes the problems that will occur after this article is set up:

 

1. Host Name Verification Failed

Javax.net. ssl. SSLKeyException: [Security: 090482] BAD_CERTIFICATE alert was received ed from 192.168.140.3-192.168.140.3. check the peer to determine why it rejected the certificate chain (trusted CA configuration, hostname verification ). SSL debug tracing may be required to determine the exact reason the certificate was rejected.

Solution:

1. Set the Server Load balancer of the host node and the managed node to advanced --> host name verification -- select none and then restart the service.

2. Make sure that the new computer is consistent with the host name.

2. Failed to authenticate the Node Manager user name and password

This occurs when the host is located on Host 1, the managed node is located on host 2, and the computer created on the console points to host 2 and the status is inaccessible.

 

<Feb 19,201 7 3:24:59 am pst> <Error> <NodeManager> <BEA-300033> <cocould not execute command "getVersion" on the node manager. reason: "Access to domain 'test' for user 'grzvthu3hw 'denied".>

Solution:

 

Step 1: Set the username and password of nodemanager on the domain Security page of the Master management server console. Step 2: Modify the file under the domain of host 2 ( Note that the nm_password.properties In the config under the domain is not the nm_password.properties In the Node Manager.), Username = weblogic password = password

/Weblogic/Oracle/Middleware/user_projects/domains/test/config/nodemanager/nm_password.properties

Step 3: restart nodemanager of host 2 3. HOST 2 managed node startup Error

I. <BEA-090870> <The realm "myrealm" failed to be loaded: weblogic. security. service. securityServiceException: com. bea. common. engine. serviceInitializationException: weblogic. security. spi. providerInitializationException: A failure occurred attempting to load LDIF for provider Authorizer from file/weblogic/Oracle/Middleware/wlserver_10.3/server/lib/XACMLAuthorizerInit. ldift .. weblogic. security. service. securityServiceException: com. bea. common. engine. serviceInitializationException:

Ii. weblogic. security. service. SecurityServiceRuntimeException: [Security: 090399] Security Services Unavailable

Iii. <BEA-000000> <cocould not decrypt the username attribute value of {AES} partition = from the file/weblogic/Oracle/Middleware/user_projects/domains/test/servers/server_03/data/nodemanager /boot. properties.

Solution:

This error occurs because the managed nodes of host 2 need to start the configuration information related to the upper and lower sides of the Management Server of host 1, and the security service authentication fails, replace all the security files in host 2 with those in HOST 1.

 

/Weblogic/Oracle/Middleware/user_projects/domains/test/security restart the service. The service is successfully started.

 

Summary:

Follow the basic steps of wenlogic dual-host Cluster

This basic step will cause many problems after building a dual-host cluster, which is very troublesome for beginners.

Suggestion: Set up HOST 1 step by step according to the steps given in the article. HOST 2 directly copies the domain created in HOST 1 to the right directory, you do not need to create a new domain. After the domain name is set up, you only need to solve the Host Name authentication problem. The dual-host Cluster

The building is successful.
