In a production environment in which applications must be reliably deployed and run, administration is more important. Administrative tasks to be performed depend on the complexity of the messaging system and of the applications it must support. Such tasks can be classified into two general categories: setup operations and maintenance operations.
Administrative setup operations in a production environment typically include some or all of the following:
Setting the password for the default administrative user ( admin) (Changing the Default Administrator Password)
Managing the contents of a file-based user repository ( Populating and Managing a User Repository) or configuring the broker to use an existing LDAP user repository (Editing the Instance Configuration File)
Controlling the operations that individual users or groups are authorized to perform (User Authorization: The Access Control Properties File)
Setting up encryption services using the Secure Socket Layer (SSL) (Message Encryption)
Setting up and configuring an LDAP object store ( LDAP Server Object Stores)
Creating connection factories and destinations ( Adding Administered Objects)
Creating a cluster configuration file (Using a Cluster Configuration File)
Designating a master broker (Master Broker)
Configuring a broker to use a persistent store ( Configuring a Persistent Data Store).
Setting a destination’s configuration properties to optimize its memory usage (Updating Physical Destination Properties, Chapter 15, Physical Destination Property Reference)
Because application performance, reliability, and security are at a premium in production environments, message service resources must be tightly monitored and controlled through ongoing administrative maintenance operations, including the following:
Broker administration and tuning
Using broker metrics to tune and reconfigure a broker ( Chapter 11, Analyzing and Tuning a Message Service)
Managing broker memory resources (Routing Services)
Creating and managing broker clusters to balance message load (Chapter 9, Working With Broker Clusters)
Recovering failed brokers (Starting Brokers).
Adjusting connection factory attributes to ensure the correct behavior of client applications (Connection Factory Attributes)
Monitoring and managing physical destinations ( Chapter 6, Managing Physical Destinations)
Controlling user access to destinations ( Access Control for Physical Destinations)
