Wildfly 8 Administration Guide Pdf 22
Configuration in WildFly is centralized, simple and user-focused. The configuration file is organized by subsystems that you can easily comprehend and no internal server wiring is exposed. All management capabilities are exposed in a unified manner across many forms of access. These include a CLI, a web based administration console, a native Java API, an HTTP/JSON based REST API, and a JMX gateway. These options allow for custom automation using the tools and languages that best fit your needs.

WildFly takes an aggressive approach to memory management. The base runtime services were developed to minimize heap allocation by using common cached indexed metadata over duplicate full parses, which reduces heap and object churn. The administration console is 100% stateless and purely client driven. It starts instantly and requires zero memory on the server. These optimizations combined enable WildFly to run with stock JVM settings and also on small devices while leaving more headroom for application data and supports higher scalability.
To manipulate the files and add users we provide a utility add-user.shand add-user.bat to add the users and generate the hashes, to add a useryou should execute the script and follow the guided process.The full details of the add-user utility are described later but for thepurpose of accessing the management interface you need to enter thefollowing values: -
A logger resource uses the path subsystem=logging/logger=$categorywhere $category is the of the logger. For example to a logger namedorg.wildfly.example would have a resource path ofsubsystem=logging/logger=org.wildfly.example.
The JMS server configuration is done through the messaging-activemqsubsystem. In this chapter we are going outline the frequently usedconfiguration options. For a more detailed explanation please consultthe Artemis user guide (See "Component Reference").
The configuration options discussed in this section assume that the theorg.wildfly.extension.messaging-activemq extension is present in yourconfiguration. This extension is not included in the standardstandalone.xml and standalone-ha.xml configurations included in theWildFly distribution. It is, however, included with thestandalone-full.xml and standalone-full-ha.xml configurations.
1. Go to YOUR_WILDFILY_HOME_DIR\docs/contrib/scripts. Example: C:\opt\wildfly-17.0.0.Final\docs/contrib/scripts 2. Copy the service folder to C:\opt\wildfly-17.0.0.Final\bin
Weld assumes requests are single threaded, and uses thread locals to isolate requests. This means that if user created threads are used then built in implementation of the session scope, the request scope and the conversation scope, will become dissociated, and you will find they are no longer active in the new thread, nor able to access their contextual data. The Weld reference guide contains information on how to associate a request to a context and activate it. Doing this in your new thread will cause the contexts to be active, and contain the same contextual data.
Each version of WildFly is shipped with given version of Weld. However, for every Weld release we also prepare a patch for WildFly which allows you to easily upgrade Weld version. The patch has a form of .zip file with name such as wildfly-10.1.0.Final-weld-3.0.0.Beta1-patch.zip. The above indicates that the patch is meant for WildFly version 10.1.0.Final and applies Weld in version 3.0.0.Beta1. Using this patch for other WildFly versions is not guaranteed to work.
Activiti development can be done with the IDE of your choice. If you would like to use the Activiti Designer then you need Eclipse Kepler or Luna.Download the eclipse distribution of your choice from the Eclipse download page. Unzip the downloaded file and then you should be able to start it with the eclipse file in the directory eclipse.Further in this user guide, there is a section on installing our eclipse designer plugin.
All classes that have .impl. in the package name are internal implementation classes and cannot be considered stable. However, if the user guide mentions those classes as configuration values, they are supported and can be considered stable.
The async executor of Activiti 5 is the only available job executor in Activiti 6 as it is a more performant and more database friendly way of executing asynchronous jobs in the Activiti Engine.The old job executor of Activiti 5 is removed. More information can be found in the advanced section of the user guide.
The AsyncExecutor is a component that manages a thread pool to fire timers and other asynchronous tasks. Other implementations are possible (for example using a message queue, see the advanced section of the user guide).
As described above, the way to interact with the Activiti engine is through the services exposed by an instance of the org.activiti.engine.ProcessEngine class. The following code snippets assume you have a working Activiti environment, i.e. you have access to a valid org.activiti.engine.ProcessEngine. If you simply want to try out the code below, you can download or clone the Activiti unit test template, import it in your IDE and add a testUserguideCode() method to the org.activiti.MyUnitTest unit test.
With multilevel administration, any permissions which apply to a container object also apply to all individual objects within that container. For example, when a host administrator role is assigned to a user on a specific host, the user gains permissions to perform any of the available host operations, but only on the assigned host. However, if the host administrator role is assigned to a user on a data center, the user gains permissions to perform host operations on all hosts within the cluster of the data center.
Roles and permissions are the properties of the user. Roles are predefined sets of privileges that permit access to different levels of physical and virtual resources. Multilevel administration provides a finely grained hierarchy of permissions. For example, a data center administrator has permissions to manage all objects in the data center, while a host administrator has system administrator permissions to a single physical host. A user can have permissions to use a single virtual machine but not make any changes to the virtual machine configurations, while another user can be assigned system permissions to a virtual machine.
A data center administrator is a system administration role for a specific data center only. This is useful in virtualization environments with multiple data centers where each data center requires an administrator. The DataCenterAdmin role is a hierarchical model; a user assigned the data center administrator role for a data center can manage all objects in the data center with the exception of storage for that data center. Use the Configure button in the header bar to assign a data center administrator for all data centers in the environment.
A cluster administrator is a system administration role for a specific cluster only. This is useful in data centers with multiple clusters, where each cluster requires a system administrator. The ClusterAdmin role is a hierarchical model: a user assigned the cluster administrator role for a cluster can manage all objects in the cluster. Use the Configure button in the header bar to assign a cluster administrator for all clusters in the environment.
A network administrator is a system administration role that can be applied for a specific network, or for all networks on a data center, cluster, host, virtual machine, or template. A network user can perform limited administration roles, such as viewing and attaching networks on a specific virtual machine or template. You can use the Configure button in the header bar to assign a network administrator for all networks in the environment.
A host administrator is a system administration role for a specific host only. This is useful in clusters with multiple hosts, where each host requires a system administrator. You can use the Configure button in the header bar to assign a host administrator for all hosts in the environment.
A storage administrator is a system administration role for a specific storage domain only. This is useful in data centers with multiple storage domains, where each storage domain requires a system administrator. Use the Configure button in the header bar to assign a storage administrator for all storage domains in the environment.
A virtual machine pool administrator is a system administration role for virtual machine pools in a data center. This role can be applied to specific virtual machine pools, to a data center, or to the whole virtualized environment; this is useful to allow different users to manage certain virtual machine pool resources.
oVirt Engine provides two default virtual disk user roles, but no default virtual disk administrator roles. One of these user roles, the DiskCreator role, enables the administration of virtual disks from the VM Portal. This role can be applied to specific virtual machines, to a data center, to a specific storage domain, or to the whole virtualized environment; this is useful to allow different users to manage different virtual resources.
Notes: Red Hat OpenShift supports many features and functions which affect scalability, Pod scheduling, idling, and resource quota/limiting features. The previous calculations are guidelines, and you may be able to tune your actual environment for better resource use or smaller total environment size. OpenShift Platform Plus customers should take into account the needs of the additional software applications (Red Hat Advanced Cluster Management, Red Hat Advanced Cluster Security, and Quay) including storage and compute resources, even though they may not require additional worker subscriptions. If working with a third-party reseller, please refer to their specific terms and agreements for Red Hat products and services.
