UWP property group

UWP is the Universal Window (portlet) Player, also referred to as UPP— Universal Portlet Playback engine. This is the portlet content handling framework that provides a uniform mechanism for portlet execution. UWP provides a portlet container and a personalization engine.

Properties are listed in alphabetical order for ease of reference.

UWP property name	Default value	Description
CacheRefreshList	127.0.0.1	Comma-separated list of internally addressable machines names to refresh the cache. Example: `CacheRefreshList= machine1.$DOMAIN, machine2.$DOMAIN` You should update this list for a multimachine EP configuration.
ContentCacheMaxEntries	250	The maximum number of entries in the portlet ContentCache object. This is used for caching resolved portlet contents.
ContentCacheLRU ReductionSize	5	The number of entries removed at time from the Portlet ContentCache object when implementing the LRU policy. This is used with caching content of resolved portlets.
DefaultTemplateName	Template1	The default template used for single-element portlet. See Chapter 8, “Building Templates.” You can change this to any template you want. For example, if you wanted every portlet to use the same header logo or footer, you could create that template and enter that template’s name here. When you change the template name here, it changes the default template for all resource IDs.
ErrorFile	/logs/uwp.err	Location and name of the file to log error messages, relative to the value for WorkRoot.
ObjectCacheLRUReduction Size	5	The number of least recently used (LRU) entries removed at a time from the UWPObjectCache object when implementing the LRU policy. The LRU policy is a page-replacement policy that removes from main memory the pages that show the least amount of recent activity. This policy is based on the assumption that these pages are the least likely to be used again in the immediate future. This value is used for clickthru_cache, windows_def_omt_cache, and parsed_template_cache.
ObjectCacheMaxEntries	250	Every object that goes into and out of the database gets cached. This value is the maximum number of entries allowed in the UWPObjectCache object. This value is used for clickthru_cache, windows_def_omt_cache, and parsed_template_cache.
StorageConnector	onepage-generic	Values – onepage-instantdb, onepage-generic, onepage-cloudscape, onepage-cloudscape-iplanet. WARNING! Do not change this value.
ThisMachineName	127.0.0.1	The host name or IP address of this machine. If this machine is also a cache server, the value of ThisMachineName and UWPCacheServer must match.
TraceFile	/logs/uwp.trc	Location and name of the file to log trace messages, relative to the value for WorkRoot.
TraceOn	false	(true/false) Used for basic tracing. This value should be set to “off” in a production environment.
UsePreCompiledJSP	false	(true/false) Set to “true” to have the application use precompiled JSP that are built ahead of time (.WAR file mode).
UWPCacheServer	127.0.0.1	The cache server is used for clickthru. If this machine is also a cache server, the value of ThisMachineName and UWPCacheServer must be the same. WARNING! Do not change this value.
UWPIntegrationHost	localhost.domain	Used by BEA/Yahoo integrations to make requests for portlet playback, edit screens, and returning to the OEM portal screens. This name must be visible from outside the firewall.
UWPWebServiceHost	localhost.domain	This property must be the actual name of the machine that is a server for the Web services WSDL files. This name must be visible from outside the firewall.
VerboseTrace	false	(true/false) Used for detailed tracing. This value should be set to “false” in a production environment.

Default value

Description

CacheRefreshList

127.0.0.1

Comma-separated list of internally addressable machines names to refresh the cache.

Example:

CacheRefreshList= machine1.$DOMAIN, machine2.$DOMAIN

You should update this list for a multimachine EP configuration.

ContentCacheMaxEntries

250

The maximum number of entries in the portlet ContentCache object. This is used for caching resolved portlet contents.

ContentCacheLRU ReductionSize

The number of entries removed at time from the Portlet ContentCache object when implementing the LRU policy. This is used with caching content of resolved portlets.

DefaultTemplateName

Template1

The default template used for single-element portlet. See Chapter 8, “Building Templates.” You can change this to any template you want. For example, if you wanted every portlet to use the same header logo or footer, you could create that template and enter that template’s name here.

When you change the template name here, it changes the default template for all resource IDs.

ErrorFile

/logs/uwp.err

Location and name of the file to log error messages, relative to the value for WorkRoot.

ObjectCacheLRUReduction Size

The number of least recently used (LRU) entries removed at a time from the UWPObjectCache object when implementing the LRU policy.

The LRU policy is a page-replacement policy that removes from main memory the pages that show the least amount of recent activity. This policy is based on the assumption that these pages are the least likely to be used again in the immediate future.

This value is used for clickthru_cache, windows_def_omt_cache, and parsed_template_cache.

ObjectCacheMaxEntries

250

Every object that goes into and out of the database gets cached. This value is the maximum number of entries allowed in the UWPObjectCache object. This value is used for clickthru_cache, windows_def_omt_cache, and parsed_template_cache.

StorageConnector

onepage-generic

Values – onepage-instantdb, onepage-generic, onepage-cloudscape, onepage-cloudscape-iplanet.

WARNING! Do not change this value.

ThisMachineName

127.0.0.1

The host name or IP address of this machine. If this machine is also a cache server, the value of ThisMachineName and UWPCacheServer must match.

TraceFile

/logs/uwp.trc

Location and name of the file to log trace messages, relative to the value for WorkRoot.

TraceOn

false

(true/false) Used for basic tracing.

This value should be set to “off” in a production environment.

UsePreCompiledJSP

false

(true/false) Set to “true” to have the application use precompiled JSP that are built ahead of time (.WAR file mode).

UWPCacheServer

WARNING! Do not change this value.

UWPIntegrationHost

localhost.domain

Used by BEA/Yahoo integrations to make requests for portlet playback, edit screens, and returning to the OEM portal screens. This name must be visible from outside the firewall.

UWPWebServiceHost

localhost.domain

This property must be the actual name of the machine that is a server for the Web services WSDL files. This name must be visible from outside the firewall.

VerboseTrace
