This is needed to restart the WAS cluster. It does so by first stopping the JVM and then kickstarting it again.
The entire configuration in the central repository in the IBM WAS stored is called Master Repository. The one-way communication that happens from the master to local repository is known as Sync.
Yes, even if the DMGR is down the applications can run without any problems. However, if any changes or modifications need to be executed via the DMGR then there could be a potential problem involved.
The three ways to deploy an application in WebSphere are as follows… scripts, DMGR and Hot deployment.
The following are the types of files that could be deployed in WebSphere…WAR, JAR, EAR, SAR module.
When multiple URLs are contained it is known as a virtual host. This can be either IP or FQDN based on a single application.
For HTTP it is 9080 and for HTTPS it is 9443.
The available WebSphere editions that are available are as follows… WAS – Network Deployment, WAS – Developers, WAS – z/OS, WAS – Hypervisor, WAS – Express, WAS – Base and WAS – Liberty core.
Some of the common issues which any user would potentially experience are as follows… virtual host not defined, logs not moving, internal server error, out of memory exception, slowness, JVM not starting up, High CPU/ memory and disk utilization.
A horizontal cluster is across multiple nodes and serves in a cell and a vertical cluster has its members on the same server or node.
A memory management system that automatically frees up the objects which are currently not being utilized in the program, is known as Garbage Collection.
If the WebSphere needs to be restarted all over, it automatically generates its own startup script which ensures a boost in its programming systems.
In order for the sync to function the node agent must be stopped.
When a node is added to the Cell, it is known as the Federation in WebSphere. Depending on the node sizes, it take a varying amount of time. Q15) What is the full form of FFDC?
The full form of FFDC is the first failure data capture.
The default language for scripting in WebSphere is JACL
Yes in a single JVM it is possible to deploy several applications deployment. The only condition is that the context root for each respective application must be unique.
Along with WebSphere the other databases that can be supported are as follows… DB2, Oracle Database, Microsoft SQL Server and Sybase
The two ways to connect are as follows… using proxypass and using the plugin.
Yes a web server is required for increased maintenance, security, and performance.
