HATS apps on a zSeries Servers
To enhance performance of HATS applications running on a z/Series server, use the WebSphere Administrative Console to adjust certain settings and values.
- Set...
Servers | Application Servers | server1 | ORB Service | Advanced Settings | Workload Profile...to LONGWAIT.
- For...
Servers | Application Servers | server1 | Server Instance | Multiple Instances Enabled...check the box.
- Set the...
Servers | Application Servers | server1 | Server Instance | Minimum Number of Instances...to a valid number.
- Set the...
Servers | Application Servers | server1 | Server Instance | Maximum Number of Instances...to a valid number.
- Set the...
Servers | Application Servers | server1 | Process Definitions | JVM | Initial Heap Size...value to an appropriate value for your installation..
- Set the...
Servers | Application Servers | server1 | Process Definitions | JVM | Max Heap Size...value to an appropriate value for your installation..
In addition, IBM recommends that you add the following variables under Manage WebSphere Variables and set the values as listed:
- protocol_http_tcp_no_delay =1
- protocol_http_max_persist request=1
- protocol_http_timeout_input=0
- protocol_http_timeout_output=0
- protocol_http_timeout_persistentSession=0
Enabling graphics support for HATS on z/Series
HATS enables you to transform host data such as tables into graphs on a Web page. Java APAR PQ78790 is required to support the complete graphing capabilities of HATS applications running on zSeries. These HATS applications require the Java Abstract Windowing Toolkit (AWT) and therefore need access to an Xwindows server. In the WebSphere Administrative Console, under Manage WebSphere Variables, you need to add the DISPLAY environment variable, and set the value to x.xx.xx.xx:0.0, where x.xx.xx.xx:0.0 is the XWindows environment variable that defines the IP address of the XWindows terminal.
