What's New in SAS/IntrNet 9.0 and 9.1Application Dispatcher

Overview

Application Dispatcher provides Application Broker and Load Manager enhancements, additional server encodings for z/OS, a new logging feature, new options for the PROC APPSRV statement, file upload capability, and enhanced documentation.

Note:

• This section describes the features of SAS/IntrNet: Application Dispatcher that are new or enhanced since SAS 8.2.
• z/OS is the successor to the OS/390 operating system. SAS/IntrNet 9.1: Application Dispatcher is supported in both the OS/390 and z/OS operating environments and, throughout this document, any reference to z/OS also applies to OS/390, unless otherwise stated.

Details

SAS/IntrNet: Application Dispatcher includes the following enhancements:

• The Application Dispatcher samples are now part of the samples database.
• You can now use Application Dispatcher to upload one or more files to your Application Server.
• The Application Broker default welcome page can be replaced by a customized welcome page.
• SAS Enterprise Guide 3.0 includes experimental support for building SAS/IntrNet: Application Dispatcher applications. You can use SAS Enterprise Guide to generate or modify SAS programs and to generate input HTML forms for your SAS/IntrNet applications. See the Working with SAS/IntrNet Applications section in the SAS Enterprise Guide product Help for more information.
• The _NOLOG_ feature enables you to create special macro symbols that can be sent to the Application Server without publishing the macro values in the APPSRV log.
• SAS/IntrNet: Application Dispatcher now supports the following additional parameters for starting the Load Manager:

  -maxreq=minutes

  specifies the maximum time it should take for the Application Server to send a BUSY state after the Application Server is allocated to the Application Broker.

  -maxrun=minutes

  specifies the expected maximum job run-time in minutes before an Application Server is declared as hung.

  -maxstart=minutes

  specifies the maximum time that it should take an Application Server to start.

  -nokill

  specifies not to kill a pool server that is marked as hung.

  -workdir=directory

  enables you to specify the current working directory as a start parameter for the Load Manager.

• You can obtain an Application Server activity report by using the Application Broker and running the LOADCURRENT program.
• The documentation now includes a sample Web application that demonstrates some of the features of Application Dispatcher sessions. The sample application is an online library. Users can login, select one or more items to check out of the library, and request by e-mail that the selected items be delivered. The sample code shows how to create a session and then create, modify, and view macro variables and data sets in that session.
• Two additional versions of the Application Broker have been developed for heavily loaded systems where performance is critical. The two new modules are broker.dll (ISAPI Windows) and broker.so (GWAPI z/OS).
• For z/OS, the SAS®9 Application Broker requires that the IBM Web maintenance patch, PQ47248, be installed if you intend to use a Web server codepage (FSCP) other than ibm-1047.
• SAS/IntrNet: Application Broker on z/OS now supports Windows server encodings in addition to the previously supported ISO-8859 encodings. New encodings include
  • wlatin1 (Western Europe): This value is the default in all cases except when the Web server is using IBM-870 or IBM-1025 encoding.
  • wlatin2 (Eastern Europe): This value is the default when the Web server is using IBM-870 encoding.
  • wcyrillic (Cyrillic): This value is the default when the Web server is using IBM-1025 encoding.

  The z/OS Application Broker also supports a new ISO-8859 encoding:

  • ISO-8859-15 (Latin9): This encoding is recommended only if your Web server and SAS System are using any of the IBM-114x encodings.

  SAS/IntrNet: Application Broker on z/OS now supports the following additional Web server fscp encodings:

  • EBCDIC1140 (North America)
  • EBCDIC1141 (Austria/Germany)
  • EBCDIC1142 (Denmark/Norway)
  • EBCDIC1143 (Finland/Sweden)
  • EBCDIC1144 (Italy)
  • EBCDIC1145 (Spain)
  • EBCDIC1146 (United Kingdom)
  • EBCDIC1147 (France)
  • EBCDIC1148 (International)
• The _DEBUG option now supports a list of case-insensitive keywords that can be entered to indicate which debug values to enable.
• The ConnectionError directive enables users to specify the message to be displayed when there is an Application Server connection error.
• The SHAREPOLL= and NOSHAREPOLL options enable the PROC APPSRV statement to control the period of SAS/SHARE libref polling and to disable polling of the SAS/SHARE server librefs, respectively.
• Load Manager log filename directives have been added to enable the rollover of Load Manager log files. Special codes inserted into the log filename specify the format and frequency for creating log files.
• Documentation for the BrokerPassword directive was added. The directive enables users to specify a password in order to protect the Application Broker administration interface.
