Comparing Files is one of very common task as a DBA, System Administrator. There are tonnes of Oracle,Websphere,linux configuration files. Often I have to compare one server to another and locate changes between environments.
In a Network Deployment environment, the deployment manager maintains the master repository for all of the WebSphere Application Server nodes and servers that it manages in the cell. Copies of the files that each node needs are replicated to that node by a process known as synchronization.
You should check if application server process is running to determine a crash. To do this, you need to know process ID of application server. You can find process ID at server name.pid file in:
Often the websphere default systmout,systemerror logs doesn’t provide detailed information on error. In such cases have a look at directory logs under /opt/IBM/WebSphere/AppServer/profiles/Profile01/dmgr/logs/ffdc & /opt/IBM/WebSphere/AppServer/profiles/Profile01/Node/logs/ffdc
How does Deployment Manager and node Agent work together? Does deployment manager send message to node agent actively or node agent sends message to deployment manage?
Basic Definitions:
WebSphere architectures contain one or more computer systems, which are referred to in WebSphere terminology as nodes. Nodes exist within a WebSphere cell. A WebSphere cell can contain one node on which all software components are installed or multiple nodes on which the software components are distributed.
