Introduced in Feature Pack 2

di-preprocess utility

The di-preprocess utility extracts and flattens WebSphere Commerce data and then outputs the data into a set of temporary tables inside the WebSphere Commerce database. The data in the temporary tables is then used by the index building utility to populate the data into search indexes with the Data Import Handler (DIH).

The preprocess utility picks the wc-dataimport-preprocess-fullbuild.xml file or wc-dataimport-preprocess-deltabuild.xml file first, and then transforms the results of the SQL statements defined in those files into temporary tables. Next, the utility handles each configuration XML file in a random order.

Parameter values

full-path
Required: The full directory location of the preprocessing configuration files, for example: CommerceServer70/instances/instance name/search/pre-processConfig/MC_10001/DB2.
The names of these files start with wc-dataimport-preprocess, for example, wc-dataimport-preprocess-fullbuild.xml. The search index setup utility installs this set of files when you deploy WebSphere Commerce search.
Tip: To preprocess both the catalog entry index and the category index at the same time, specify the full path for the catalog entry index only. It then processes the configuration files for both the catalog entry index and the category index by default. This is because the directory which contains the configuration files for the category index (called CatalogGroup) is located one level below the directory for the catalog entry index (called CatalogEntry).
For the catalog entry index: by default, the configuration files install at the following path:
  • SolarisLinuxAIXWindowsWC_installdir/instances/instance_name/search/pre-processConfig/MC_masterCatalogId/databaseType
  • For IBM i OS operating systemWC_instance_root/instances/instance_name/search/pre-processConfig/MC_masterCatalogId/databaseType
  • WebSphere Commerce DeveloperWCDE_installdir/search/pre-processConfig/MC_masterCatalogId/databaseType
Introduced in Feature Pack 3For the category index: by default, the configuration files install in a directory called CatalogGroup, one level below the catalog entry index configuration files, for example:
  • SolarisLinuxAIXWindowsWC_installdir/instances/instance_name/search/pre-processConfig/MC_masterCatalogId/databaseType/CatalogGroup
  • For IBM i OS operating systemWC_instance_root/instances/instance_name/search/pre-processConfig/MC_masterCatalogId/databaseType/CatalogGroup
  • WebSphere Commerce DeveloperWCDE_installdir/search/pre-processConfig/MC_masterCatalogId/databaseType/CatalogGroup
Feature Pack 6 or laterFor the inventory index: by default, the configuration files install in a directory called Inventory, one level below the catalog entry index configuration files, for example:
  • SolarisLinuxAIXWindowsWC_installdir/instances/instance_name/search/pre-processConfig/MC_masterCatalogId/databaseType/SubTypes/Inventory
  • For IBM i OS operating systemWC_instance_root/instances/instance_name/search/pre-processConfig/MC_masterCatalogId/databaseType/SubTypes/Inventory
  • WebSphere Commerce DeveloperWCDE_installdir/search/pre-processConfig/MC_masterCatalogId/databaseType/SubTypes/Inventory
instance
The name of the WebSphere Commerce instance with which you are working (for example, demo).
dbuser

DB2The name of the user who is connecting to the database.

OracleThe user ID connecting to the database. If you are using workspaces, the database user must be granted cross-schema privileges to create and drop tables. Otherwise, you cannot preview changes made in workspaces.

dbuserpwd
The password for the user who is connecting to the database.
Feature Pack 8Alternatively, you can use the passwordFile parameter to specify the encrypted password from a file.
fullbuild
Optional: A flag that indicates whether it is a full index build. The accepted values are either true or false. The default value is true.
localename
Optional: The locale that should be indexed. The accepted values are either:
  • All
Or one of the following values:
  • en_US
  • fr_FR
  • de_DE
  • it_IT
  • es_ES
  • pt_BR
  • zh_CN
  • zh_TW
  • ko_KR
  • ja_JP
  • ru_RU
  • ro_RO
  • pl_PL
The default value is All.
Introduced in Feature Pack 3onelevel
Introduced in Feature Pack 3Optional: A flag you can use to save time when setting up preprocessing for the catalog entry index (CatalogEntry indextype) and the category index (CatalogGroup indextype) at the same time. If you set the onelevel flag to true, then for the full-path value, you only need to specify the path to the preprocessing configuration files for the catalog entry index. The utility will automatically look for the category index files in the CatalogGroup directory one level down.

Example:

  • Instead of specifying both paths for your full-path value, as shown here:
    C:/Program Files/IBM/WebSphere/CommerceServer70/instances/demo/search/pre-processConfig/MC_10001/DB2,
    C:/Program Files/IBM/WebSphere/CommerceServer70/instances/demo/search/pre-processConfig/MC_10001/DB2/CatalogGroup
  • Specify only the first path, as shown here:
    C:/Program Files/IBM/WebSphere/CommerceServer70/instances/demo/search/pre-processConfig/MC_10001/DB2

The default value of the onelevel flag is true.

Introduced in Feature Pack 3multithread
Introduced in Feature Pack 3Optional: Preprocesses data by using multiple threads.
Introduced in Feature Pack 3The number of threads used is based on the number of existing wc-dataimport-preprocess-XXXXX.xml files, excluding the wc-dataimport-preprocess-fullbuild.xml and wc-dataimport-preprocess-deltaupdate.xml files.
Introduced in Feature Pack 3The default value is false.
Feature Pack 5 or laterworkspace
Feature Pack 5 or laterThe workspace index to preprocess. This value is case-sensitive. If specified, the specified workspace index is preprocessed. If not specified, the base schema index is preprocessed. The default value is to preprocess the base schema index.
To get the workspace ID, either:
  • Open the workspace in the Workspace Management tool in the Management Center. The workspace code is the workspace ID; or
  • If the workspace has an active task group, run the following SQL query: select * from cmwsschema, where the workspace ID is listed under the workspace column.
Feature Pack 5 or laterOracledbURL
Feature Pack 5 or laterOracle1 The database URL the utility uses to connect to the database. If not provided, the utility constructs a database URL based on the default database value.
Feature Pack 7 or laterskipDeltaNoEntry
Feature Pack 7 or laterOptional: When delta preprocessing (fullbuild set to false), the utility checks if there are any delta updates to perform. The utility ends if there are no delta updates to perform. Otherwise, the preprocessing is performed as expected.
Feature Pack 7 or laterIf this parameter is set to false, and there are no delta updates to perform, the delta preprocessing updates all of the temporary tables to empty. This might save time, where the utility would otherwise check all the tables and process no records.
Feature Pack 7 or laterThe default value is false.

Feature Pack 7You must apply the interim fix for APAR #JR50553 to use this parameter.

Feature Pack 7 or laterpublishedOnly
Feature Pack 7 or laterOptional: Allows only products from published categories to be displayed in the keyword search results when deep category unpublish is enabled.
Feature Pack 7Note: Interim fixes for Feature Pack 7 are required to use this parameter. Apply the latest cumulative interim fix for Feature Pack 7, JR52306.fep.
Feature Pack 7 or laterThe default value is false.
Feature Pack 7 or laterdeepUnpublish
Feature Pack 7 or laterOptional: Enables preprocessing for the deep category unpublish feature.
Feature Pack 7Note: Interim fixes for Feature Pack 7 are required to use this parameter. Apply the latest cumulative interim fix for Feature Pack 7, JR52306.fep.
Feature Pack 7 or laterThe default value is false.
Feature Pack 7 or laterFor more information, see Hiding categories and products using deep category unpublish.
Feature Pack 7 or laterdeepSequence
Feature Pack 7 or laterOptional: Enables preprocessing for the deep search sequencing feature.
Feature Pack 7Note: Interim fixes for Feature Pack 7 are required to use this parameter. Apply the latest cumulative interim fix for Feature Pack 7, JR52306.fep.
Feature Pack 7 or laterThe default value is false.
Feature Pack 7 or laterFor more information, see Hiding categories and products using deep category unpublish.
Feature Pack 8passwordFile
Feature Pack 8Optional: The full path to the password.properties file that contains the password for the user who is connecting to the database. For example, C:\password.properties.
Feature Pack 8The password.properties file contains the following content:

dbUserPassword=encrypted_pwd
Where encrypted_pwd is the password that has been encrypted using the wcs_encrypt utility.
Feature Pack 8nonLangTables
Feature Pack 8Optional: Preprocesses only language-insensitive tables.
Feature Pack 8Language-insensitive tables use the following naming convention: TI_string_number. For example, TI_CATENTRY_0.
Feature Pack 8The default value is false.
Feature Pack 8langTables
Feature Pack 8Optional: Preprocesses only language-sensitive tables.
Feature Pack 8Language-sensitive tables use the following naming convention: TI_string_number_number. For example, TI_ATTR_0_1 for United States English.
Feature Pack 8The default value is false.
Feature Pack 8Usage notes for language table parameters:
  • When both nonLangTables and langTables values are set to false, all tables are preprocessed.
  • If setting both values to true, first run the utility with nonLangTables, then run the utility with langTables.
  • For sites with many supported languages enabled, you can preprocess only language-insensitive tables first, and then parallelly preprocess language-sensitive tables.
Feature Pack 8dropTempTable
Feature Pack 8Indicates whether to drop tables when preprocessing the search index.
Feature Pack 8Passing in a value of false uses a TRUNCATE statement on the tables.
Feature Pack 8The default value is true, which uses a DROP statement on the tables.
Note: This parameter supports only DB2 9.7 or later, or Oracle databases.
Feature Pack 8propFile
Feature Pack 8The full path to the properties file to pass in to the utility.
