[Spacewalk-list] Recommendations for Tuning Spacewalk

[Matthew Madey]

We use Oracle, so I don't know any of the Postgres tunings.. but here are
some you might find helpful for tuning Apache\Tomcat\Java\Networking

Add maxThreads to /etc/tomcat6/server.xml



    <Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"
address="127.0.0.1" maxThreads="1024" maxKeepAliveRequests="1000"/>

    <!-- A "Connector" using the shared thread pool-->

    <!--

    <Connector executor="tomcatThreadPool"

               port="8080" protocol="HTTP/1.1"

               connectionTimeout="20000"

               redirectPort="8443" />



    <!-- Define an AJP 1.3 Connector on port 8009 -->

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
URIEncoding="UTF-8" address="127.0.0.1" maxThreads="1024"/>



    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
URIEncoding="UTF-8" address="::1" maxThreads="1024"/>





Tune Apache to service more requests /etc/httpd/conf.d/zz-spacewalk-server.conf

</IfModule>



Include /etc/rhn/satellite-httpd/conf/rhn/rhn_monitoring.conf







 Also added some network tuning to /etc/sysctl.conf



net.ipv4.icmp_echo_ignore_broadcasts = 1

net.ipv4.conf.all.secure_redirects = 0

net.ipv4.tcp_max_syn_backlog = 8192

net.ipv4.conf.default.secure_redirects = 0

net.ipv4.tcp_syncookies = 1

net.ipv4.conf.all.accept_source_route = 0

net.ipv4.conf.all.rp_filter = 1

net.ipv4.conf.all.send_redirects = 0

net.ipv4.conf.default.accept_redirects = 0

net.ipv4.conf.all.accept_redirects = 0

net.ipv4.conf.default.send_redirects = 0

net.core.somaxconn = 1536

net.core.dev_weight = 512

##3x normal for a queue and budget suited to networks greater than 100mbps

net.core.netdev_budget = 10000

net.core.netdev_max_backlog = 30000



Depending on the amount of memory on your Spacewalk server, you may
want to increase your JAVA_OPTS Xms and Xmx settings to something a
little higher. Typically only needed if you are seeing Java Heap out
of memory errors in your Spacewalk logs.


Best of luck!
