New parameter in nodemanager.properties

with 2 comments

While creating a presentation about the startup sequence of WebLogic server I noticed a new parameter in the nodemanager.properties of a 10.3.4 domain:

DomainsDirRemoteSharingEnabled=false

This parameter was mentioned to me in a SR just recently as hidden feature, though the SR is about a 10.3.3 nodemanager in combination with a shared filesystem for the domain. Since the parameter didn’t solve the issue I didn’t blog about it *yet*. AFAIK no documentation exists about this parameter today, so I can only guess the exact working. I *think* (hope!) it is a parameter to instruct the nodemanager to do some more extensive checking on a managed server than just bluntly starting a managed server based on the contents of $DOMAIN_HOME/servers/$SERVER_NAME/data/nodemanager directory .

More to come later.

**UPDATE**
A very friendly Advance Resolution Engineer gave me this description of the parameter:

Introduced a Nodemanager property called DomainsDirRemoteSharingEnabled. When this property is enabled, the Node Manager adds NMHostName property to the servers startup.properties file while starting the server. While recovering the server, the Node Manager compares the NMHostName property in the startup.properties file with the hostname on which it is currently running and if it matches then only NM will recover the server.

  1. “While recovering the server, the Node Manager compares the NMHostName property in the startup.properties file with the hostname on which it is currently running and if it matches then only NM will recover the server.”
    So this should fix your recovery problem when running multiple hosts (and so NMs) against a shared domain dir?

    I wonder if this parameter appeared in 10.3.3 but only worked properly from 10.3.4?

    • The parameter was introduced in 10.3.3. I know for sure because support sent me a backport-patch. (twice, you can guess why 😉 )
