This chapter outlines how to tune configuration properties for the operating system on which WebCenter Portal applications are installed, WebCenter Portal applications, and their back-end components.
Oracle WebCenter Portal 11g is an integrated suite of products used to create social applications, enterprise portals, communities, composite applications, and internet or intranet Web sites on a standards-based, service-oriented architecture (SOA). Oracle WebCenter Portal combines the development of rich internet applications, a multi-channel portal framework, and a suite of horizontal Enterprise 2.0 applications, which provide content, presence, and social networking capabilities to create a highly interactive user experience. Interacting with services such as instant messaging, blogs, wikis, RSS, tags, discussion forums, activities and social networks directly within the context of a portal or an application improves user and group productivity and enhances the return on IT investments.
Oracle WebCenter Portal: Spaces is an out-of-the-box WebCenter Portal application that brings you the latest technology in terms of social networking, communication, collaboration, and personal productivity with no development effort. Through the robust set of integrated services and applications provided by Oracle WebCenter Portal's Framework, Composer, and Resource Catalog, the Spaces application enables you to deploy instant community portals, team sites and other collaborative applications.
For more information about Oracle WebCenter Portal, see Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal and Oracle Fusion Middleware Developer's Guide for Oracle WebCenter Portal.
The tuning considerations in this section apply to most WebCenter Portal and WebCenter Portal: Spaces deployments and usage scenarios. It is highly recommended that you review these configurations and implement those that are appropriate for your use case scenarios.
To run a WebCenter Portal application at moderate load, set the open-files-limit
to 4096
. If you encounter errors, such as running out of file descriptors, then increase the system limit.
For example, on Linux, you can use this command:
ulimit -n 8192
Refer to your operating system documentation to find out how to change this system limit.
The following data source settings are the defaults for mds-SpacesDS
and WebCenterDS
. These settings can be adjusted depending on the application's usage pattern and load.
<jdbc-connection-pool-params> <initial-capacity>10</initial-capacity> <max-capacity>50</max-capacity> <capacity-increment>1</capacity-increment> <shrink-frequency-seconds>0</shrink-frequency-seconds> <highest-num-waiters>2147483647</highest-num-waiters> <connection-creation-retry-frequency-seconds>0</connection-creation-retry-frequency-seconds> <connection-reserve-timeout-seconds>60</connection-reserve-timeout-seconds> <test-frequency-seconds>0</test-frequency-seconds> <test-connections-on-reserve>true</test-connections-on-reserve> <ignore-in-use-connections-enabled>true</ignore-in-use-connections-enabled> <inactive-connection-timeout-seconds>0</inactive-connection-timeout-seconds> <test-table-name>SQL SELECT 1 FROM DUAL</test-table-name> <login-delay-seconds>0</login-delay-seconds> <statement-cache-size>5</statement-cache-size> <statement-cache-type>LRU</statement-cache-type> <remove-infected-connections>true</remove-infected-connections> <seconds-to-trust-an-idle-pool-connection>60</seconds-to-trust-an-idle-pool-connection> <statement-timeout>-1</statement-timeout> <pinned-to-thread>false</pinned-to-thread> </jdbc-connection-pool-params>
To edit JDBC data source settings:
Login to WebLogic Server Administration Console.
From the Home page, select Summary of JDBC Data Sources, Settings for mds-SpacesDS, and then the Connection Pool tab.
Edit properties, as required.
To edit WebCenter Portal data source settings:
Login to WebLogic Server Administration Console.
From the Home page, select Summary of JDBC Data Sources and navigate to the Connection Pool tab.
See also "Tuning Data Source Connection Pools" in Oracle Fusion Middleware Configuring and Managing JDBC Data Sources for Oracle WebLogic Server.
JVM arguments are set in the setDomainEnv.sh
file on Unix operating systems and setDomainEnv.cmd
on Windows operating systems. The setDomainEnv
file is located in the <domain_dir>/bin directory.
WebLogic Server production mode: When Webcenter is installed for production deployment, the WebLogic Server is set to production mode. However, if it is installed for development and then switched to production mode for better performance, you need to include the following parameter in the startup command:
-Dweblogic.ProductionModeEnabled=true
For information on setting your domain to production mode using the Administration Console, see "Change to production mode" in the Oracle Fusion Middleware Oracle WebLogic Server Administration Console Online Help.
Heap size: If the server is overloaded, that is, garbage is collected or out of memory error occurs frequently, then increase the heap size as appropriate to your server's available physical memory.
For more information, see Section 2.4.1.1, "Specifying Heap Size Values" and "Set Java options for servers started by Node Manager" in the Oracle Fusion Middleware Oracle WebLogic Server Administration Console Online Help.
The following parameters can be modified in the server's startup command or through the Administration Console to increase heap size:
jrockit vm: -Xms2048M -Xmx2048M -Xns512M hotspot vm: -Xms2048M -Xmx2048M -XX:MaxPermSize512M
If clients connect to your server using relatively slow connections, that is, using modems or VPN from remote locations, consider compressing content before it downloads to the client. While content compression increases the load on the server, the client's download experience is much improved.
Several content compression methods are available. The following steps describe how to use the mod_deflate
module from Apache.
Enable mod_deflate
module on Apache.
To do this, add the following to httpd.conf ($OH/instances/$INSTANCE_NAME/config/OHS/$OHS_NAME)
LoadModule deflate_module "${ORACLE_HOME}/ohs/modules/mod_deflate.so"
Setup the Output Filter and specify the rules for compression.
Here is a sample snippet that you can add to the httpd.conf
(same location mentioned above). Modify the content based on your content and the compression requirements.
<IfModule mod_deflate.c> SetOutputFilter DEFLATE AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/xml AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE image/svg+xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/atom+xml AddOutputFilterByType DEFLATE application/x-javascript AddOutputFilterByType DEFLATE text/html SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary SetEnvIfNoCase Request_URI \.(?:pdf|doc?x|ppt?x|xls?x)$ no-gzip dont-vary SetEnvIfNoCase Request_URI \.avi$ no-gzip dont-vary SetEnvIfNoCase Request_URI \.mov$ no-gzip dont-vary SetEnvIfNoCase Request_URI \.mp3$ no-gzip dont-vary SetEnvIfNoCase Request_URI \.mp4$ no-gzip dont-vary </IfModule>
For more information about mod_deflate
, refer to: http://httpd.apache.org/docs/2.0/mod/mod_deflate.html
This section describes parameters that enable administrators to tune performance of WebCenter Portal applications.
This section includes the following:
The default session timeout for a Spaces application is derived from the HTTP session timeout specified in web.xml. The out-of-the-box web.xml setting for <session-timeout>
is 45 minutes. See Setting HTTP Session Timeout.
Administrators can use the wcSessionTimeoutPeriod
attribute in webcenter-config.xml to increase or decrease the session timeout if required. See also "webcenter-config.xml" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
To manage overall resource usage, adjust the application's http session timeout value, in minutes, in the web.xml
file. In general, shorter session timeout values correspond to less memory and CPU usage on the server.
If you must modify this property, post deployment, you must edit web.xml
manually. See "Editing web.xml Properties" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The following is a sample snippet of web.xml
:
<session-config> <session-timeout> 45 </session-timeout> </session-config>
You can specify an integer value, in seconds, after which any JSP page will be removed from memory if it has not been requested in the web.xml
file. This frees up resources in situations where some pages are called infrequently.
Increasing the value reduces user response time, and decreasing it reduces application memory foot print. The default value for is 600 seconds or 10 minutes. If jsp_timeout is not specified, it means there is no timeout.
To modify this property post deployment, you must edit web.xml
manually. See "Editing web.xml Properties" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The following is a sample snippet of web.xml
:
<servlet> <servlet-name> oraclejsp <init-param> <param-name> jsp_timeout </param-name> <param-value> 600 </param-value> </init-param>
Through this setting, you can control the number of pages users can navigate using the browser Back button without losing page state. To reduce CPU and memory usage, you can decrease the value in the web.xml
file.
If you must modify this property, post deployment, you must edit web.xml
manually. See "Editing web.xml Properties" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The following is a sample code snippet of web.xml
:
<context-param> <param-name> org.apache.myfaces.trinidad.CLIENT_STATE_MAX_TOKENS </param-name> <param-value> 3 </param-value> </context-param>
Through this setting, you can control ADF View State Compression. By default this setting is enabled (parameter value is 'True') and all non-current view states are compressed before saving in memory, which reduces the heap usage.
Though not recommended for WebCenter Portal, you can disable this property by editing the web.xml manually. See "Editing web.xml Properties" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal
The following is a sample code snippet of web.xml
:
<context-param> <param-name> org.apache.myfaces.trinidad.COMPRESS_VIEW_STATE </param-name> <param-value> false </param-value> </context-param>
The default MDS cache size is 100MB. If you encounter the error message, JOC region full, then you can increase the MDS cache size in the adf-config.xml
file.
Post deployment, modify these properties through the System MBeans Browser. For more information, see the section "Changing MDS Configuration Attributes for Deployed Applications" in Oracle Fusion Middleware Administrator's Guide.
The following is a sample snippet of adf-config.xml
:
<cache-config> <max-size-kb>150000</max-size-kb> </cache-config>
Consider setting the MDS auto-purge seconds-to-live
parameter (as shown in the example below) to remove older versions of metadata automatically every hour. By default the auto-purge seconds-to-live="-1"
which means no purge. However, if the WebCenter Portal site changes frequently, such as when creating or editing spaces or pages, then auto-purge should be set to an appropriate value to remove older version of metadata for optimal performance.
If excessive metadata is accumulated and each purge is very expensive, reduce this interval in the adf-config.xml
file.
The following is a sample snippet of adf-config.xml
:
<auto-purge seconds-to-live="3600"/>
To ensure the initial purge does not impact ongoing user activities, consider using the following WLST command to induce an MDS purge immediately before the bulk of the user load hits the system:
The following example shows how to purge all documents in the application repository whose versions are older than 10 seconds:
wls:/weblogic/serverConfig>purgeMetadata(application='[AppName]',server='[ServerName]',olderThan=10)
Concurrency management includes global settings that impact the entire WebCenter Portal and service- and resource-specific settings that only impact a particular service.
You can define deployment-specific overrides or additional configuration in the adf-config.xml
file. For example, you can specify resource-specific (producers) values that are appropriate for a particular deployment.
The following describes the format of the global, service, and resource entries in adf-config.xml
:
<concurrent:adf-service-config xmlns="http://xmlns.oracle.com/webcenterportal/concurrent/config"> <global queueSize="SIZE" poolCoreSize="SIZE" poolMaxSize="SIZE" poolKeepAlivePeriod="TIMEPERIOD" timeoutMinPeriod="TIMEPERIOD" timeoutMaxPeriod="TIMEPERIOD" timeoutDefaultPeriod="TIMEPERIOD" timeoutMonitorFrequency="TIMEPERIOD" hangMonitorFrequeny="TIMEPERIOD" hangAcceptableStopPeriod="TIMEPERIOD" /> <service service="SERVICENAME" timeoutMinPeriod="TIMEPERIOD" timeoutMaxPeriod="TIMEPERIOD" timeoutDefaultPeriod="TIMEPERIOD" /> <resource service="SERVICENAME" resource="RESOURCENAME" timeoutMinPeriod="TIMEPERIOD" timeoutMaxPeriod="TIMEPERIOD" timeoutDefaultPeriod="TIMEPERIOD" /> </concurrent:adf-service-config>
Where:
SIZE
: A positive integer. For example: 20.
TIMEPERIOD
: Any positive integer followed by a suffix indicating the time unit, which must be one of: ms
for milliseconds, s
for seconds, m
for minutes, or h
for hours. For example: 50ms
, 10s
, 3m
, or 1h
. The following are examples of default settings for different services. These settings are overwritten with any service-specific configurations in connections.xml
or adf-config.xml
files:
<concurrent:adf-service-config xmlns="http://xmlns.oracle.com/webcenter/concurrent/config"> <service service="oracle.webcenter.community" timeoutMinPeriod="2s" timeoutMaxPeriod="50s" timeoutDefaultPeriod="30s"/> <resource service="oracle.webcenter.community" resource="oracle.webcenter.doclib" timeoutMinPeriod="2s" timeoutMaxPeriod="10s" timeoutDefaultPeriod="5s"/> <resource service="oracle.webcenter.community" resource="oracle.webcenter.collab.calendar.community" timeoutMinPeriod="2s" timeoutMaxPeriod="10s" timeoutDefaultPeriod="5s"/> <resource service="oracle.webcenter.community" resource="oracle.webcenter.collab.rtc" timeoutMinPeriod="2s" timeoutMaxPeriod="10s" timeoutDefaultPeriod="5s"/> <resource service="oracle.webcenter.community" resource="oracle.webcenter.list" timeoutMinPeriod="2s" timeoutMaxPeriod="10s" timeoutDefaultPeriod="5s"/> <resource service="oracle.webcenter.community" resource="oracle.webcenter.collab.tasks" timeoutMinPeriod="2s" timeoutMaxPeriod="10s" timeoutDefaultPeriod="5s"/> </concurrent:adf-service-config>
Note:
All of the attributes except service
and resource
are optional, and therefore, for example, the following tags are valid:
<global queueSize="20"/> <resource service="foo" resource="bar" timeoutMaxPeriod="5s"/>
You can use the Enterprise Manager System MBean Browser to view, add, modify, and delete the concurrency configuration based on your usage pattern. To access the MBean Browser for your WebCenter Portal application, see "Accessing the System MBean Browser" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
In System MBean Browser, navigate to:
Application Defined MBeans -> oracle.adf.share.config -> Server: (your server name) -> Application: (your application name) ->ADFConfig -> ADFConfig (bean) -> ADFConfig -> WebCenterConcurrentConfiguration -> Operations -> listResource
To view the current concurrency settings, select listResource, and then click Invoke (Figure 27-2).
Figure 27-2 System MBean Browser - listResource
To change a setting, select setResource, enter the resource details, and then click Invoke (Figure 27-3).
Figure 27-3 System MBean Browser - setResource
Take care to enter the correct values for service, resource, name and value.
NOTE: If the resource parameter you are attempting to modify already has a [value] setting, you must remove the setting first by invoking the [removeResource] operation (Figure 27-4).
To save changes, navigate to Application Defined MBeans: ADFConfig:ADFConfig -> save, and click Invoke.
This section describes performance configuration for back-end services used by WebCenter Portal applications. Performance of back-ends such BPEL servers or Oracle WebCenter Content servers, for example, should be tuned as described in guidelines for those back-ends.
This section includes the following sub sections:

If you are experiencing performance issues post login, especially in the area of permission checks, you may need to tune the policy store parameters as described in Section 26.3.5, "OPSS PDP Service Tuning Parameters". Depending on your use case scenarios, performance of WebCenter Portal and WebCenter Portal: Spaces, specifically, can be improved by modifying the following parameters:
Set oracle.security.jps.policystore.rolemember.cache.warmup.enable
to True
Modify oracle.security.jps.policystore.rolemember.cache.size
based on the number of active groups you expect to have in your WebCenter Portal - Spaces environment.
NOTE: This parameter should only be modified if you expect to have more than 3000 active Spaces in your WebCenter Portal: Spaces environment.
Set oracle.security.jps.policystore.policy.cache.size
to 5 times the number of group spaces
Note:
Always refer to your own use case scenarios before modifying the policy store parameters. For more information, see the Oracle Fusion Middleware Security and Administrator's Guide for Web Services before tuning any security parameters.
This section describes portlet performance-related configuration. This section includes the following sub sections:
Setting DefaultServedResourceRequiresWsrpRewrite for WSRP Portlets
Setting DefaultProxiedResourceRequiresWsrpRewrite for WSRP Portlets
To manage overall resource usage and user response time, you can remove unnecessary locale support, modify portlet timeout and cache size in the adf-config.xml
file.
For the Portlet service, 28 supported locales are defined out-of-the-box. You can remove the locales that are unnecessary for your application.
If you must modify these properties, post deployment, you must edit adf-config.xml
manually. See "Editing adf-config.xml" in the Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The following is a sample snippet of adf-config.xml
:
<portletC:adf-portlet-config xmlns="http://xmlns.oracle.com/adf/portlet/config"> <supportedLocales> <value>es</value> <value>ko</value> <value>ru</value> <value>ar</value> <value>fi</value> <value>nl</value> <value>sk</value> <value>cs</value> <value>fr</value> <value>no</value> <value>sv</value> <value>da</value> <value>hu</value> <value>pl</value> <value>th</value> <value>de</value> <value>it</value> <value>pt</value> <value>tr</value> <value>el</value> <value>iw</value> <value>pt_BR</value> <value>zh_CN</value> <value>en</value> <value>ja</value> <value>ro</value> <value>zh_TW</value> </supportedLocales> <defaultTimeout>20</defaultTimeout> <minimumTimeout>1</minimumTimeout> <maximumTimeout>300</maximumTimeout> <parallelPoolSize>10</parallelPoolSize> <parallelQueueSize>20</parallelQueueSize> <cacheSettings enabled="true"> <maxSize>10000000</maxSize> </cacheSettings> </portletC:adf-portlet-config>
You can modify the portlet cache size in the adf-config.xml
file. The default portlet cache size is set to 10 MB.
If you must modify these properties, post deployment, you must edit adf-config.xml
manually.
The following is a sample snippet of adf-config.xml
:
<adf-portlet-config> .... <supportedLocales> <cacheSettings enabled="true"> <maxSize>10000000</maxSize> </cacheSettings> </adf-portlet-config>
Oracle recommends that you enable the Java Object Cache (JOC) for WSRP producers so that objects written to the persistent store are cached.
The following is a sample snippet of web.xml
:
<env-entry>
<env-entry-name>oracle/portal/wsrp/server/enableJavaObjectCache
</env-entry-name>
<env-entry-type>java.lang.String
</env-entry-type>
<env-entry-value>false
</env-entry-value>
</env-entry>
To suppress the optimistic render of WSRP portlets after a WSRP PerformBlockingInteraction
or HandleEvents
call, set the Portlet container runtime option (specified in portlet.xml) as follows: com.oracle.portlet.suppressWsrpOptimisticRender=true
.
true
- optimistic render always suppressed
false
- optimistic render may be performed
Normally, if a WSRP portlet receives a WSRP PerformBlockingInteraction
request (processAction
in JSR168/JSR286 portlets) and the portlet does not send any events as a result, the WSRP producer renders the portlet and returns the portlet's markup in the response to the PerformBlockingInteraction
SOAP message. This markup may be cached by the consumer until the consumer's page renders, and if nothing else affecting the state of the portlet happens (such as the portlet receiving an event), the cached markup can be used by the consumer, eliminating the need for a second SOAP call to GetMarkup
.
This assumes that the portlet's render phase is idempotent, which is always a best practice. However, if the portlet expects to receive an event, or rendering the portlet is more costly than a second SOAP message for GetMarkup
, the developer may use this container option to suppress the optimistic render of the portlet after a processAction
or handleEvent
call. The portlet still renders normally when the producer receives the WSRP GetMarkup
request.
To manage overall resource usage for a Web producer, you can tune the Connection Timeout property:
Default: 30000 ms
Minimum: 5000 ms
Maximum: 60000 ms
Post deployment, modify the Connection Timeout property through Fusion Middleware Control or using WLST. For details, see:
"Editing Producer Registration Details Using Fusion Middleware Control" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
"Editing Producer Registration Details Using WLST" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The following is a sample snippet of connections.xml
:
<webproducerconnection producerName="wc-WebClipping" urlConnection="wc-WebClipping-urlconn" timeout="10000" establishSession="true" mapUser="false"/>
You can use the WebCenter Portal-specific excludedActionScopeRequestAttributes
container runtime option to specify how to store action-scoped request attributes so that they are available to portlets until a new action occurs.
Request attributes which match any of the regular expressions are not stored as action-scoped request attributes if the javax.portlet.actionScopedRequestAttributes
container runtime option is used, in addition to any request parameters whose values match the regular expressions defined in the com.oracle.portlet.externalScopeRequestAttributes container runtime option.
If set to true, you can specify a second value of numberOfCachedScopes
and a third value indicating the number of scopes to be cached by the portlet container.
To specify the default WSRP requiresRewrite
flag to use when generating Resource URLs for portlet-served resources, set the Portlet container runtime option (specified in portlet.xml) as follows: com.oracle.portlet.defaultServedResourceRequiresWsrpRewrite
.
This setting is used for all ResourceURLs created by the portlet, unless overridden by the presence of the oracle.portlet.server.resourceRequiresRewriting
request attribute when the ResourceURL methods write()
or toString()
are called. This setting is also used to specify the WSRP requiresRewriting
flag on the served resource response, but can be overridden by the presence of the oracle.portlet.server.resourceRequiresRewriting
request attribute when the portlet's serveResource()
method returns.
Valid values:
unspecified
- (Default) The requiresRewrite
URL flag is not given a value, and the requiresRewriting
response flag for a serveResource
operation is based on the MIME type of the response.
true
- The requiresRewrite
URL flag and requiresRewriting
response flag is set to true
, indicating that the resource should be rewritten by the consumer.
false
- The requiresRewrite
URL flag and requiresRewriting
response flag is set to false
, indicating that the resource does not necessarily need to be rewritten by the consumer, though the consumer may choose to rewrite the resource.
To specify the default WSRP requiresRewrite
flag to use when encoding URLs for resources not served by the portlet, set the Portlet container runtime option (specified in portlet.xml) as follows: com.oracle.portlet.defaultProxiedResourceRequiresWsrpRewrite
.
This setting is used for all URLs returned by the PortletResponse.encodeURL()
method, unless overridden by the presence of the oracle.portlet.server.resourceRequiresRewriting
request attribute when the PortletResponse.encodeURL()
method is called.
Valid values:
true
- (Default) The requiresRewrite
URL flag is set to true, indicating that the resource should be rewritten by the consumer.
false
- The requiresRewrite
URL flag is set to false, indicating that the resource does not necessarily need to be rewritten by the consumer.
To specify to a portal consumer that the CSS file is imported to an IFramed portlet, set the Portlet container runtime option (specified in portlet.xml) as follows: com.oracle.portlet.importCssToIFrame
.
Valid values:
true
- The CSS file from the consumer is applied to an IFramed portlet.

You can modify the portlet timeout value in the adf-portlet-config
element of the adf-config.xml
file. Default: 10 seconds, minimum: 0.1 seconds, maximum: 60 seconds.
If you must modify these properties, post deployment, you must edit adf-config.xml
manually. See "Editing adf-config.xml" in the Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The following is a sample snippet of adf-config.xml
:
<adf-portlet-config> .... <defaultTimeout>5</defaultTimeout> <minimumTimeout>2</minimumTimeout> <maximumTimeout>300</maximumTimeout> </adf-portlet-config>
To manage overall resource usage for OmniPortlets, you can tune the Connection Timeout property:
Default: 30000 ms
Minimum: 5000 ms
Maximum: 60000 ms
Post deployment, modify the Connection Timeout property through Fusion Middleware Control or using WLST. For details, see:
"Editing Producer Registration Details Using Fusion Middleware Control" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
"Editing Producer Registration Details Using WLST" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The following is a sample snippet of connections.xml
:
<webproducerconnection producerName="wc-OmniPortlet" urlConnection="wc-OmniPortlet-urlconn" timeout="10000" establishSession="false" mapUser="false"/>
