Progress
Installation and Configuration Guide
Version 9
for UNIX
Java
Many Version 9 products require one or more installed Java components for subsequent use by Progress. Specifically, the components are the Java Run-time Environment (JRE) and the Java Development Kit (JDK).
The JDK contains the software and tools that developers need to compile, debug, and run applets and applications written using the Java programming language. The JDK software and documentation, typically included with each new release of an operating system, are available for download at the vendor’s Web site. You will require a JDK if you intend to develop Java stored procedures and triggers with the Database, or to create Java proxies with the Open Client Toolkit.
The JRE consists of the Java Virtual Machine, the Java Core Classes, and supporting files. The JRE is the run time part of the JDK and does not include a compiler, a debugger, or development tools. You will need the JRE if you intend to use one of the following:
You will also need the JRE to execute Java stored procedures and triggers from the database.
The installation program automatically installs the correct JRE if you install Progress 9.1 products on either of the following 32-bit platforms:
Additionally, the following list identifies 64-bit platforms that install the 32-bit JRE:
On the Sun Solaris platform, the Progress Version 9.1 installation program also automatically installs the JDK when you install a Version 9 product that requires the JDK.
In some cases, you might need to install some required Java components, as described below:
- HP-UX — The installation program does not automatically install the JDK component if you install Progress on this platform. If you want access to the JDK and do not already have it installed, you should install the required version of the JDK on your target system. For more information on Java requirements, see Table 1–1.
Additionally, it may be necessary for you to adjust the default kernel parameter max_thread_proc. To determine whether the default kernel parameter is too low and should be modified, contact your HP or system administrator.
- HP Tru64, AIX, and Linux platforms — The installation program does not automatically install the JRE or JDK component if you install Progress component on one of these platforms. You must install the required version of the JRE and/or the JDK (if not already installed) on your target system. For more information on Java requirements, see Table 1–1.
- SQL-92 — The installation program does not automatically install the JDK component when you install the Enterprise Database, the Personal Database, or the Workgroup Database with SQL Client Access. If you intend to develop Java stored procedures and Java triggers for your database, you must install a Progress development product such as ProVision. For information on writing Java stored procedures and triggers, see the Progress SQL-92 Guide and Reference .
Table 1–1 lists operating systems and specifies the versions of JDK and JRE each supports. To generate this information for your system, type java -version at the command line. In the case of the Open Client toolkit, other versions, including versions from other vendors, can be used as well. When Javasoft provides a JDK and JRE for a certain platform, Progress Software includes the JDK and JRE in its distribution. For other systems, you must obtain the JDK from the system’s operating system vendor. Please contact your operating system vendor for assistance in obtaining the JDK.
