Basic parameters |
Index |
It is similar to the schema or name of a relational database. Multiple indexes for entire DB migration are separated by commas (,). You can enter index aliases. You can also enter an expression containing wildcard characters, for example, asterisks (*). If you select multiple indexes, their structure must be the same. This parameter can be configured as a macro variable of date and time and a path name can contain multiple macro variables. When the macro variable of date and time works with a scheduled job, the incremental data can be synchronized periodically. For details, see Incremental Synchronization Using the Macro Variables of Date and Time.
NOTE:
If you have configured a macro variable of date and time and schedule a CDM job through DataArts Studio DataArts Factory, the system replaces the macro variable of date and time with (Planned start time of the data development job – Offset) rather than (Actual start time of the CDM job – Offset). |
