Status: Verified
FACT(s) (Environment):
Progress 9.1D
Tomcat 4.1
Apache 1.3
Apache 2.0
SYMPTOM(s):
Slow application response with the AIA using HTTP through Apache and Tomcat JSE
Using Apache 2.0.x and mod_jk module
Using Tomcat 4.1.x with Coyote/JK2 AJP 1.3 Connector
Response time is slower than using the Jrun or ServletExec JSEs
No connection errors reported in the application or in the log files
Using 9.1D06 on the client, AIA and the Appserver side
CAUSE:
Bug# OE00095428
FIX:
Upgrade to Progress 9.1E or later
Upgrade to OpenEdge 10.1A or later
Workaround:
Use different Tomcat connector for the ajp13 protocol.
1) Locate the $TOMCAT_HOME/conf/server.xml file, where
$TOMCAT_HOME is the Tomcat's installation directory
2) In the server.xml file locate the following line:
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
3) Comment out that section in the xml file by adding the
leading "<!--" and trailing "-->" tags.
4) Locate the following line:
<Connector className="org.apache.ajp.tomcat4.Ajp13Connector"
5) Uncomment that section in the xml file by removing the
leading "<!--" and trailing "-->".
4) Restart the Tomcat and Apache before starting the application.
