4 Oracle Fusion Middleware Administration

This chapter describes issues associated with Oracle Fusion Middleware administration. It includes the following topics:

General Issues and Workarounds

This section describes configuration issues and their workarounds. It includes the following topics:

MDS purgeMetadata Command Can Take a Long Time

When autopurge is not enabled or manual purge is not frequently executed, the MDS database repository may have a lot of older (non-tip) versions accumulated. In this situation, the next purge operation may take a very long time (possibly hours). You may need to terminate the purge operation to avoid affecting the system performance. Currently, it is not possible to terminate the purge operation using Oracle Fusion Middleware tools. Instead, you must terminate the operation at the database level.

To terminate the purge operation, contact the DBA. The DBA can identify the database session where the purgeMetadata operation is executing and kill the session to stop the purge. Note that MDS purges 300 documents in each iteration, commits the change, and repeats until all purgeable documents are processed. As a result, killing the database session does not affect already committed purge iterations.

Node Manager May Return An Error About ADR

In some circumstances, when you start a Managed Server from the Administration Console, an error similar to the following is logged on the Node Manager console. It indicates an issue while initializing Automatic Diagnostic Repository (ADR).

SEVERE: failure initializing ADR oracle.dfw.common.DiagnosticsException: failure loading adrci binary from the system path: null
Cause: DFW-40112: There was an error executing adrci commands; the following errors have been found "null"

You can ignore this error because Node Manager does not use ADR.

SSL Certificate Chain Is Required on Certain Browsers

When you configure SSL for Oracle HTTP Server, you may need to import the entire certificate chain (rootCA, Intermediate CA’s and so on).

Certain browsers, for example Internet Explorer, require that the entire certificate chain be imported to the browsers for the SSL handshake to work. If your certificate was issued by an intermediate CA, you will need to ensure that the complete chain of certificates is available on the browser or the handshake will fail. If an intermediate certificate in the chain expires, it must be renewed along with all the certificates (such as OHS server) in the chain.

Configuration Issues and Workarounds

This section describes configuration issues and workarounds. It includes the following topic:

Fusion Middleware Control Incorrectly Refers to Shared Service Tables

The Service table page of Fusion Middleware Control contains a mention of shared service tables. Shared service tables are not supported.

Deprecated and Desupported Features

The following administrative feature is desupported beginning in 12c (12.2.1.3):

  • Moving from test to production.

    The scripts and procedures used to move your environment from a test to a production environment is no longer supported. However, if you want to change the network configuration, such as host name, network domain name, or IP address, you can use the chghost utitlity, as described in About Changing the Network Configuration in Administering Oracle Fusion Middleware.

Documentation Errata for Administering Oracle Fusion Middleware

The following lists the documentation errata for administration issues:

Using WLST with the Lifecycle Managment Tools

Issue

In an SSL-only domain, to connect to a server using WLST, you must set some properties for the start, stop, and discovery actions to succeed.

[ -Dweblogic.security.SSL.ignoreHostnameVerification=true    -Dweblogic.security.TrustKeyStore=DemoTrust ]    [ -Dweblogic.security.JavaStandardTrustKeyStorePassPhrase=password]     [ -Dweblogic.security.CustomTrustKeyStoreFileName=filename      -Dweblogic.security.TrustKeystoreType=jks     [ -Dweblogic.security.CustomTrustKeyStorePassPhrase=password]]     [ -Dweblogic.security.SSL.hostnameVerifier=classname]

For more information about setting the properties, see Using the WebLogic Scripting Tool in Understanding the WebLogic Scripting Tool.

For more information about the start, stop, and discovery actions, see Additional Information About Standard Actions in Configuring Oracle Fusion Middleware Using Lifecycle Management Tools.
