Configure Source and Output File Directories for Multiple Nodes
Configure Source and Output File Directories for Multiple Nodes
When the Data Integration Service runs on primary and back-up nodes or on a grid, DTM instances can run jobs on each node with the compute role. Each DTM instance must be able to access the source and output file directories. To run mappings that manage metadata changes in flat file sources, each Data Integration Service process must be able to access the source file directories.
When you configure the source and output file directories for a Data Integration Service that runs on multiple nodes, consider the following guidelines:
You can configure the
Source Directory
property to use a shared directory to create one directory for source files.
If you run mappings that manage metadata changes in flat file sources and if the Data Integration Service grid is configured to run jobs in separate remote processes, you must configure the
Source Directory
property to use a shared directory.
If you run other types of mappings or if you run mappings that manage metadata changes in flat file sources on any other Data Integration Service grid configuration, you can configure different source directories for each node with the compute role. Replicate all source files in all of the source directories.
If you run mappings that use a persistent lookup cache, you must configure the
Cache Directory
property to use a shared directory. If no mappings use a persistent lookup cache, you can configure the cache directory to have a different directory for each node with the compute role.
You can configure the
Target Directory
,
Temporary Directories
, and
Reject File Directory
properties to have different directories for each node with the compute role.
To configure a shared directory, configure the directory in the Execution Options on the
Properties
view. You can configure a shared directory for the home directory so that all source and output file directories use the same shared home directory. Or, you can configure a shared directory for a specific source or output file directory. Remove any overridden values for the same execution option on the
Compute
view.
To configure different directories for each node with the compute role, configure the directory in the Execution Options on the
