|
btreePageSize
|
Oracle Commerce Internal Use. Oracle
Commerce does not recommend modifying this property.
The number of children per btree node. This value must be
greater than
0. The default is 100.
The Record Store validates that the
btreePageSize property is greater than
0. If this property is not correctly
set,
RecordStore.setConfiguration() throws a
RecordStoreConfigurationException.
|
|
changePropertyNames
|
The
changePropertyNames configuration property
specifies which record properties to examine when determining whether a record
has changed.
The
changePropertyNames configuration property is
useful because it allows you to specify exactly which record properties are
evaluated to determine if that record has changed between crawls (in other
words, if the record is different from the previous generation's record in the
Record Store instance).
If not specified, the value of
changePropertyNames defaults to all the
properties on a record.
If you choose to specify the value
changePropertyNames, here are several
suggested properties:
File system
crawls:
Endeca.Document.Text,
Endeca.FileSystem.ModificationDate
CMS crawls:
Endeca.Document.Text,
Endeca.CMS.ModificationDate
Web crawls:
Endeca.Document.Text,
Endeca.Web.Last-Modified
If you are gathering native file system properties for file
system crawls, you can also use the ACL properties as change properties.

|
cleanerInterval
|
The
cleanerInterval property specifies how often (in
hours) the Record Store Service checks for stale generations of records in a
Record Store. (A stale generation is defined by the
generationRetentionTime property.)
This value of
cleanerInterval must be greater than or equal
to
0. If not specified, the value defaults
to
1 hour.
Fractional values (like
0.1) can be specified if you want the
service to check more frequently than once per hour. A value of
0 (zero) does not check for stale
generations.
|
|
dataDirectory
|
The
dataDirectory property specifies the location
where the Record Store’s data files are stored.
The value of the
dataDirectory property can either be an
absolute path or a path relative to the directory where the Record Store is
running. If not specified, the value defaults to
<install
path>\CAS\<version>\workspace\state\<Record store
name>. This directory is created when a Record Store instance is
created if it does not already exist.
The Record Store service validates that the
dataDirectory property specifies a directory
for which the user running the CAS Service has write permissions.

|
duplicateRecordCompressionEnabled
|
The
duplicateRecordCompressionEnabled property has
been deprecated in 3.1.2, so this property is ignored.
The
duplicateRecordCompressionEnabled property
specifies whether to store new versions of records whose
change properties have not changed. Enabling this feature
improves Record Store performance and decreases Record Store disk space.
The
duplicateRecordCompressionEnabled property
takes a Boolean value:
true does not store duplicate copies of
records, and
false stores duplicate copies of
records.
If not specified, the value defaults to
false.
|
|
generationRetentionTime
|
The
generationRetentionTime property specifies how
long (in hours) a record generation should remain in a Record Store instance
before it is considered a stale generation. The next time the
cleanerInterval value is reached, then stale
generations are deleted from the Record Store.
However, the Record Store does not remove the most recent
generation even if it exceeds the value of
generationRetentionTime, and the Record Store
does not remove the last generation specified with the
set-last-read-generation task for a client ID.
Fractional values (like
0.1) can be specified if you want a
generation to be maintained for less than an hour. If not specified,
generationRetentionTime defaults to
48 hours (two days).
The Record Store validates that the
generationRetentionTime property is greater
than or equal to
0. If set to
0, the Record Store instance only stores
the latest (single) generation after the clean up.
|
|
idPropertyName
|
The
idPropertyName property specifies the source
property from which the record ID is derived. This value must be a non-empty
string. If not specified, it defaults to
Endeca.Id.
When selecting a record property as the
idPropertyName, you should choose a property
that is present on every record and whose value is unique to each record. That
is, all records (except those tagged with Delete All) must have a single unique
non-null value for this property.
The uniqueness of the property value is important because if
two records have the same
idPropertyName property value, the second
record that is processed overwrites the first one in the Record Store.
The Record Store validates that the
idPropertyName property is a non-empty string.
If this property is not correctly set,
RecordStore.setConfiguration() throws a
RecordStoreConfigurationException.
|
|
ignoreInvalidRecords
|
The
ignoreInvalidRecords property specifies how
invalid records are handled.
Invalid records are records with missing IDs (either the
idPropertyName property is missing or it has a
null value) or with invalid action types for the
Endeca.Action property.
The
ignoreInvalidRecords property takes a Boolean
value:
If set to
true, invalid records are ignored and
a warning message is logged. The READ_WRITE operation for the records
continues.
If set to
false, an invalid record throws an
exception and stops the process.
In either case, invalid records are not added to the Record
Store. If not specified, the value defaults to
true.
During the development stage of your Record Store application,
you may want to set the
ignoreInvalidRecords property to
false so that an
InvalidRecordFault exception is thrown
whenever an invalid record is processed. This allows you to immediately see if
your source records have the appropriate properties. Once you go into
production, you can change the property to
true and monitor the logs for warning
messages about invalid records.

indexWriteFlushInterval
|
Oracle Commerce Internal Use. Oracle
Commerce does not recommend modifying this property.
This value must greater than
0. The Record Store validates that the
indexWriteFlushInterval property is greater
than
0. If this property is not correctly
set,
RecordStore.setConfiguration() throws a
RecordStoreConfigurationException.

jdbmSettings
|
Oracle Commerce Internal Use. Oracle
Commerce does not recommend modifying this property.
|
|
maxDataFileSize
|
The property
maxDataFileSize has been removed in version
3.1.2 and later.
Oracle Commerce Internal Use. Oracle Commerce does not
recommend modifying this property.
This value must be greater than
0. The default value is 2 GB.
The Record Store validates that the
maxDataFileSize property is greater than
0. If this property is not correctly
set,
RecordStore.setConfiguration() throws a
RecordStoreConfigurationException.
|
|
mergeBufferSize
|
Oracle Commerce Internal Use. Oracle Commerce
does not recommend modifying this property.
This value must be greater than 0. The default value is 131072
bytes. The Record Store validates that the
mergeBufferSize property is greater than 0. If
this property is not correctly set,
RecordStore.setConfiguration() throws a
RecordStoreConfigurationException.
|
|
recordCompressionEnabled
|
The
recordCompressionEnabled property specifies
whether records are stored on disk in a compressed format.
The
recordCompressionEnabled property takes a
Boolean value:
If set to
true, records are stored on disk in a
compressed format.
If set to
false, records are stored on disk in
an uncompressed format.
If not specified, the value defaults to
false.
|
|
writeBufferSize
|
Oracle Commerce Internal Use. Oracle Commerce does not
recommend modifying this property.
This value must be greater than 0. The default value is
104857600 bytes. The Record Store validates that the
writeBufferSize property is greater than 0. If
this property is not correctly set,
RecordStore.setConfiguration() throws a
RecordStoreConfigurationException.
