Data Set Properties

Getting there

Databridge Servers > Client Managers > Settings > Customize > (select data set) > Settings > Properties

The customizable properties for a data set are organized in the following sections:

Basic Properties

This section has two properties: Active and Mode, which correspond to the active and ds_mode columns in the DATASETS Client control table.

Disabling Active (toggle will turn gray) has the effect of disabling the mapping of the data set to the relational database. This is different than disabling Active in the Settings > Data Sets page for the data source. When disabled, the specific data set will stop the replication for the data set in question. Enabling the Active option will cause the data set to be mapped.

Note

Disabling Active for a data set that has customizations on the relational database will result in changes being lost.

Changing the Mode option to a different value is not common while customizing except in some special situations. See below for circumstances that would permit changing this option.

  • Setting the Mode to Clone (0) to force the data set to be re-cloned. Do this if reorganizing will take longer than re-cloning.

  • Following a failed Reorganize command you may want to correct the reorg script that failed. Change the Mode from Reorg Failed (33) to Reorg Needed (31) and rerun the Reorganize command, which can be restarted.

You would normally run these commands from the Settings > Data Sets menu for the data source. We provide them in the Customize command in case you need to do this while customizing.

DMSII Information

This section contains the two configuration options Item Name Prefix and Extract Priority. These options correspond to the values of the item_name_prefix and extract_priority columns in the DATASESTS Client control table.

  • Item name Prefix is used to make the Client automatically strip fixed prefixes from data item names when naming the columns in the corresponding tables in the relational database. This avoids having to do massive renames to get rid of redundant prefixes.

  • Extract Priority allows you to control the order in which items are selected when initializing the connection to the Databridge server. Data sets are extracted in the order in which they are selected. The default, is to select them in ascending structure number and record type order. When extract_priority is set to a non-zero value, items with higher extract_priority values are selected first and the structure number and record type are used to determine order when duplicates are detected. This allows you to force large data sets (for which the data extraction could take a long time) to be extracted first, as this would create more overlap shortening the duration of the clone.

Options

This section contains a series of options that allow you to change some of the bits in the ds_options column of the DATASETS table. The History Tables parameter, which controls two mutually exclusive ds_options bits is represented by a list box with 3 entries (None, Save History and Save History Only to prevent both bits from being set).

Refer to the DATASETS Client control table section of Databridge Client Administrator's Guide for more information about these bits. The various option bits are listed below with their corresponding names used in the Databridge Client Administrator's Guide and the configuration file parameter(s) that define their initial values, when applicable.

Name in UI Name in Client Administrator's Guide mask config parameter
Clear Duplicate Extract Records DSOPT_Clrdup_Recs 32,768 clr_dup_extr_recs
Ignore Duplicates DSOPT_Ignore_Dups 32 suppress_dup_warnings
History Tables > Save History DSOPT_Save_Updates 8 history_tables = 1
History Tables > Save History Only DSOPT_HistoryOnly 8192 history_tables = 2
Ignore New Columns DSOPT_Supp_New_Columns 256 suppress_new_columns

Split variable Format Dataset DSOPT_Use_AA_Only 65,536 split_varfmt_dataset
Use AA Values (or RSNs) as Keys DSOPT_Use_AA_Only 16,384
No Stored Procs in Updates DSOPT_No_StoredProcs 4 use_stored_procs
Multiple Source DSOPT_MultiSource 1024
Merged Tables DSOPT_MergedTables 2048
Use Internal Clone DSOPT_Internal_Clone 4,194,304 use_internal_clone
Use BCP utility DSUPT_Use_BCP 16,777,216 use_bcp

See the DATASETS Client Control table section of the Databridge Client Administrator's Guide for details these options. You can change the setting for these bits on a data set by date set basis using customization. You should set the parameter in the configuration file to reflect the most commonly used setting, as this will reduce the amount of changes needed.

Virtual Data Set

This section allows you to link virtual data sets and real data sets from which they are derived using the virtual_ds_num, real_ds_num and real_ds-rectype columns in the DATASETS client control table. The two controls are list-boxes that contain all qualifying data sets that can be selected.

User Columns

This section lists the various user columns that are to be added to this data set. These bit default to the value defined by the external_columns parameter in the Client configuration file. This set of options allows you to further customize the user columns to be used for the tables derived from this data set.
