The legacy root

The legacy root is a node of type ibm-wsnName some way below the container root . A typical name for this might be: ibm-wsnName=legacyRoot,ibm-wsnName=PLEX2,ibm-wsnName=domainRoots,ibm-wsnTree=t1,o=WASNaming,c=us The names legacyRoot and domainRoots are fixed. The only variable is the middle name, in this example PLEX2.

There may be several legacyRoot nodes, each with a different name. Each of these is a "domain". The WebSphere Application Server for z/OS configuration maps a domain to a sysplex. It is configured when the sysplex name is entered into the customisation dialog when WebSphere Application Server for z/OS is installed.
