Chapter 1 Introducing Jaguar CTS

Administration and development tools

Sybase Central is a common management framework for Sybase application and database servers. Jaguar provides two Sybase Central plug-ins for use by developers and administrators:

Jaguar Manager provides graphical administration facilities for Jaguar CTS, including support for development, deployment, and runtime monitoring of applications.
Security Manager provides a graphical user interface for managing SSL digital certificates. There are two versions of Security Manager: the one installed with Jaguar server controls the server's certificate database, and the standalone client version can be used by end-users to manage the certificates used in client applications.

For detailed instructions on running Jaguar Manager and Security Manager, see the Jaguar CTS System Administration Guide.

Development support

Sybase PowerBuilder 7.0 and PowerJ 3.5 have been integrated with Jaguar. Using these tools, you can develop, deploy, and debug Jaguar server components entirely within the development environment. You can also generate the proxies required for client application development. For more information, see Building Internet and Enterprise Applications in the Enterprise Application Studio online books collection.

Application developers using other tools can use Jaguar Manager to view the method definitions for any installed component in Jaguar Manager. You can view and edit method definitions graphically, or you can directly edit the IDL datatype and interface definitions with Jaguar Manager's IDL editor. Interface definitions can be imported from existing Java classes, ActiveX component type library files, or from standard CORBA IDL files. See Chapter 6, "Defining Component Interfaces", for more information.

Jaguar Manager also generates stub classes for use in Java and C++ client applications and ActiveX type libraries for use in ActiveX client applications.

Deployment support

To simplify application deployment, Jaguar Manager defines the following basic, middle-tier application units:

Clusters A cluster represents a set of Jaguar servers that share configuration information and run the same set of components. For applications with thousands of clients, clusters provide support for load balancing and high availability. Jaguar Manager provides a Synchronize feature to replicate component files and configuration information from a primary server to other servers in a cluster.
Servers A server represents one Jaguar runtime process. Each server has its own network addresses for client session connections and for HTTP (HTML) connections. All servers on one host machine share the same configuration repository. For administration purposes, you can connect to any server on the host machine to configure other servers on the same host.
Applications Applications allow you to group packages (groups of related components) and Web applications (bundled static Web content, servlets, and JSPs) into a single unit for easy deployment between servers.
Packages A package organizes components into cohesive, secure units that can be easily deployed on another Jaguar server. Packages can be exported, or saved, as a Java archive (JAR) file. The package archive includes the definition of all components in a package, plus any supporting files (such as source code and client files) that you specify. Package archives exported from one server can easily be imported for redeployment on another server.
Roles attached to packages control access to components in a package. For more information about roles and package security, see "Declarative security".

Note Do not confuse Jaguar package names with Java package names.
Components A component definition consists of the component's method signatures and other properties, such as component type, transaction support, threading model, and the name of the Java class or executable library that implements the component.
Web applications Web applications allow you to group static Web content, servlets, and JSPs) into a single unit for easy deployment and configuration.
Web components Servlets and JSPs can be installed in a Web application as Web components. Doing so allows configuration of request path mappings and other useful settings within the Web application properties.

Before a client application can execute a component, the component must be installed in a Jaguar package, and that package must be installed in the server to which the client connects.

Hot refresh support

Jaguar Manager provides a Refresh menu item to refresh components, packages, and servers. This option lets you test and debug component implementation changes without restarting the server.

Runtime monitoring support

The Jaguar Manager plugin for Sybase Central provides allows you to remotely view server log files and to monitor statistics for component execution and network activity.

The Jaguar Manager File Viewer allows you to connect to the Jaguar server and view the contents of these server log files:

The Jaguar server log file, where the Jaguar server records errors related to component execution.
The HTTP protocol request and error log files, where Jaguar's built-in Web server records successful and unsuccessful file requests.

The Runtime Monitoring folder allows you to view statistics on component and network activity. You can view counts of active client sessions, components, and transactions.

See the Jaguar CTS System Administration Guide for more information on these features.

Certificate management support

Security Manager allows you to manage the server and user certificates that are required for SSL-protocol support. Security Manager allows you to perform these tasks:

Install server certificates Server certificates are required to establish secure IIOP and HTTP ports. The certificate is presented to the client application as proof that the application has connected to the server that the user intends to interact with.
Install Certificate Administrator (CA) certificates CA certificates, also called signing certificates, are attached to client and server certificates to validate the origin of the certificate. For example, if you obtain a certificate from VeriSign, your certificate will include a copy of the VeriSign CA certificate. Using Security Manager, you can install CA certificates into Jaguar and indicate which CAs are trusted. When client applications present certificates to Jaguar, the signing certificate must be present in the list of trusted CAs in Security Manager or the connection fails.
Issue certificates for testing purposes Security Manager allows you to create new client and server certificates for use in testing your applications. To deploy Internet applications, you must obtain server certificates from a well-known Certificate Authority (CA) such as VeriSign or Thawte. Certificates signed by the internal Security Manager CA will not be recognized by client browsers unless the end user has installed the Jaguar Test CA in their browser's database of trusted CAs.

See "Security Configuration" in the Jaguar CTS System Administration Guide for more information on Security Manager.
