None

Defines a comma delimited list of httpd proxies with which this node will initially communicate. Value should be of the form:

address1:port1,address2:port2

Using the default configuration, this property can by manipulated via the jboss.modcluster.proxyList system property.

excludedContexts

ROOT,admin-console,invoker,jbossws,jmx-console,juddi,web-console

List of contexts to exclude from httpd registration, of the form:

host1:context1,host2:context2,host3:context3

If no host is indicated, it is assumed to be the default host of the server (e.g. localhost). "ROOT" indicates the root context. Using the default configuration, this property can by manipulated via the jboss.modcluster.excludedContexts system property.

autoEnableContexts

true

If false the contexts are registered disabled in httpd, they need to be enabled via the enable() mbean method or via mod_cluster_manager. Since version 1.1.0.CR1.

stopContextTimeout

10

The number of seconds to wait for clean shutdown of a context (completion of pending requests for a distributable context; or destruction/expiration of active sessions for a non-distributable context). Since version 1.1.0.CR1.

proxyURL

None

If defined, this value will be prepended to the URL of MCMP commands.

socketTimeout

20000

Number of milliseconds to wait for a response from an httpd proxy to MCMP commands before timing out, and flagging the proxy as in error.

true, if proxyList is undefined, false otherwise

If enabled, httpd proxies will be auto-discovered via multicast announcements. This can be used either in concert or in place of a static proxyList.

advertiseGroupAddress

224.0.1.105

UDP address on which to listen for httpd proxy multicast advertisements

advertisePort

23364

UDP port on which to listen for httpd proxy multicast advertisements

advertiseSecurityKey

None

If specified, httpd proxy advertisements checksums will be verified using this value as a salt

stickySession

true

Indicates whether subsequent requests for a given session should be routed to the same node, if possible.

stickySessionRemove

false

Indicates whether the httpd proxy should remove session stickiness in the event that the balancer is unable to route a request to the node to which it is stuck. This property is ignored if stickySession is false.

stickySessionForce

true

Indicates whether the httpd proxy should return an error in the event that the balancer is unable to route a request to the node to which it is stuck. This property is ignored if stickySession is false.

workerTimeout

-1

Number of seconds to wait for a worker to become available to handle a request. When all the workers of a balancer are usable, mod_cluster will retry after a while (workerTimeout/100) to find an usable worker. That is timeout in the balancer mod_proxy documentation. A value of -1 indicates that the httpd will not wait for a worker to be available and will return an error if none is available.

maxAttempts

1

Number of times an httpd proxy will attempt to send a given request to a worker before giving up. The minimum value is 1, meaning try only once. (Note that mod_proxy default is also 1: no retry).

flushPackets

false

Enables/disables packet flushing

flushWait

-1

Time to wait before flushing packets. A value of -1 means wait forever.

ping

10 seconds

Time to wait for a pong answer to a ping

smax

Determined by httpd configuration

Soft maximum idle connection count (that is the smax in worker mod_proxy documentation). The maximum value depends on the httpd thread configuration (ThreadsPerChild or 1).

ttl

60 seconds

Time to live (in seconds) for idle connections above smax

nodeTimeout

-1 (none)

Timeout (in seconds) for proxy connections to a node. That is the time mod_cluster will wait for the back-end response before returning error. That corresponds to timeout in the worker mod_proxy documentation. Note that mod_cluster always uses a cping/cpong before forwarding a request and the connectiontimeout value used by mod_cluster is the ping value.

balancer

mycluster

The balancer name

domain

None

If specified, load will be balanced among jvmRoutes with the same domain. This is primarily used in conjunction with partitioned session replication (e.g. buddy replication).

ssl

false

Should connection to proxy use a secure socket layer

sslCiphers

The default JSSE cipher suites

Overrides the cipher suites used to init an SSL socket ignoring any unsupported ciphers

sslProtocol

TLS

Overrides the default SSL socket protocol.

sslCertificateEncodingAlgorithm

The default JSSE key manager algorithm

The algorithm of the key manager factory

sslKeyStore

System.getProperty("user.home") + "/.keystore"

The location of the key store containing client certificates

sslKeyStorePass

changeit

The password granting access to the key store

sslKeyStoreType

JKS

The type of key store

sslKeyStoreProvider

The default JSSE security provider

The key store provider

sslTrustAlgorithm

The default JSSE trust manager algorithm

The algorithm of the trust manager factory

sslKeyAlias

The alias of the key holding the client certificates in the key store

sslCrlFile

Certificate revocation list

sslTrustMaxCertLength

5

The maximum length of a certificate held in the trust store

sslTrustStore

System.getProperty("javax.net.ssl.trustStorePassword")

The location of the file containing the trust store

sslTrustStorePassword

System.getProperty("javax.net.ssl.trustStore")

The password granting access to the trust store.

sslTrustStoreType

System.getProperty("javax.net.ssl.trustStoreType")

The trust store type

sslTrustStoreProvider

System.getProperty("javax.net.ssl.trustStoreProvider")

The trust store provider

masterPerDomain

false

If the domain directive is used, should HA partition use a singleton master per domain

loadMetricClass

org.jboss.modcluster.load.metric.impl.BusyConnectorsLoadMetric

Class name of an object implementing org.jboss.load.metric.LoadMetric

loadMetricCapacity

1

The capacity of the load metric defined via the loadMetricClass property

loadHistory

9

The number of historic load values to consider in the load balance factor computation.

loadDecayFactor

2

The factor by which a historic load values should degrade in significance.
