maxProcessors vs maxThreads 2004-01-15 - By Apu Shah
Back
using tomcat 5.0.16
the JK2 AJP connector
(http://jakarta.apache.org/tomcat/tomcat-5 (See http://cat-5.ora-code.com).0-doc/config/ajp.html) docs
doesn't list any directive like maxProcessors or maxThreads. the HTTP
connector does
(http://jakarta.apache.org/tomcat/tomcat-5 (See http://cat-5.ora-code.com).0-doc/config/http.html) list a
maxThreads directive.
1. is maxProcessors deprecated?
2. does maxProcessors and/or maxThreads apply to the AJP connector?
3. if i do set maxProcessors/maxThreads does the total number of
maxThreads/maxProcessors across all tomcat instances in a load balanced
setup need to equal/less than/greater than the apache serverlimit?
example:
- 2 apache servers with serverlimit 1024 each => total server limit = 2048
- 4 tomcat instances.
- should maxProcessors be set to 2048/4 = 512 or less than/greater than that?
4. similiar questions as 1&2 for maxSpareThreads/maxIdleProcessors and
minSpareThreads/minIdleProcessors.
5. does acceptCount work for both HTTP and AJP connectors?
thanks in advance for clarifications. here is the ajp connector element in
my server.xml
<!-- Define a Coyote/JK2 AJP 1.3 Connector on port 8009 -->
<Connector address="192.168.100.152" port="8009" redirectPort="8443"
debug="0" enableLookups="false"
protocol="AJP/1.3" />
do i set maxThreads, maxSpareThreads, minSpareThreads, acceptCount or
maxProcessors, maxIdleProcessors, minIdleProcessors, acceptCount?
