Chapter 2 Sybase Central Overview

Jaguar Manager

Jaguar Manager runs within Sybase Central. Use Jaguar Manager to configure EAServer and to define and deploy software components and packages. Jaguar Manager is EAServer's graphical user interface tool that allows you to easily define the packages, components, and methods that EAServer clients use to run an application.

Application developers 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 interface definition language (IDL) datatype and interface definitions with Jaguar Manager's IDL editor.

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

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

Cluster - a set of servers that share configuration information and run the same set of components.
Server - an EAServer runtime process with its own network addresses for client session connections and for HTTP (HTML) connections.
Application - a group of packages and Web applications bundled into a single unit for easy deployment between servers.
Package - a collection of components organized into cohesive, secure units that can be easily deployed on another EAServer installation.
Component - contains the methods that execute business logic and access data sources.
Web application - a unit of deployment for interrelated Web content, JavaServer Pages (JSPs), and Java servlets.
Web component - a servlet or JSPs installed in a Web application.

The Refresh menu item allows you to refresh components, packages, and servers, which lets you test and debug component implementation changes without restarting the server.

Logging errors

When you run Jaguar Manager, logging and error messages are written to the jagmgr.log file, in EAServer's bin directory.

Jaguar Manager enables you to remotely view server log files and to monitor statistics for component execution and network activity. For more information on runtime monitoring, see Chapter 12, "Runtime Monitoring"

All Properties tab

In property dialog boxes, do not use the All Properties tab to set properties that can be set on other tabs. Examples include:

For components, set the property com.sybase.jaguar.component.java.classes using the Java Classes tab.
For components, set automatic persistence properties such as mapField and mapQuery properties on the Persistence tab.

If you set these properties on the All Properties tab, changes are overwritten with the property values displayed on the other tabs.

Profile Manager

When you log in to Jaguar Manager, you can use predefined login profiles, which speeds up the connection process. Define profiles using the Profile Manager, then select the profile from the drop-down list in the Jaguar Manger login window and enter a password to connect to the port defined in the profile.

Defining a profile from the login window

Click the Profile Manager button.
Click Add and define the following fields:
- Profile Name - the name of the profile that displays in the Profiles drop-down list.
- User Name - the name of the user connecting to the port; for example, jagadmin.
  
  To log in using a profile, you must provide a password in the login window that corresponds to the user name of the login profile.
- Host Name - the host name to which you are connecting.
- Port Number - the port on the host to which you are connecting.
Click OK to add the profile.

To delete a profile, highlight the profile and click Delete.
