Configuring IBM DB2 EEE External Loader Attributes

You can configure the IBM DB2 EEE external loader to use different loading modes when loading to the database. Loading modes determine how the IBM DB2 EEE external loader loads data across partitions in the database. You can configure the IBM DB2 EEE external loader to use the following loading modes:

Split and load.
Partitions the data and loads it simultaneously using the corresponding database partitions.

Split only.
Partitions the data and writes the output to files in the specified split file directory.

Load only.
Does not partition the data. It loads data in existing split files using the corresponding database partitions.

Analyze.
Generates an optimal partitioning map with even distribution across all database partitions. If you run the external loader in split and load mode after you run it in analyze mode, the external loader uses the optimal partitioning map to partition the data.

The IBM DB2 EEE external loader creates multiple logs based on the number of database partitions it loads to. For each partition, the external loader appends a number corresponding to the partition number to the external loader log file name. The IBM DB2 EEE external loader log file format is
file_name
.ldrlog.
partition_number
.

The Integration Service does not archive or overwrite IBM DB2 EEE external loader logs. If an external loader log of the same name exists when the external loader runs, the external loader appends new external loader log messages to the end of the existing external loader log file. You must manually archive or delete the external loader log files.

For information about IBM DB2 EEE external loader return codes, see the IBM DB2 documentation.

The following table describes attributes for IBM DB2 EEE external loader connections:

Attribute	Default Value	Description
Opmode	Insert	IBM DB2 external loader operation mode. Select one of the following operation modes: Insert Replace Restart Terminate
External Loader Executable	db2atld	Name of the IBM DB2 EEE external loader executable file.
Split File Location	n/a	Location of the split files. The external loader creates split files if you configure SPLIT_ONLY loading mode.
Output Nodes	n/a	Database partitions on which the load operation is to be performed.
Split Nodes	n/a	Database partitions that determine how to split the data. If you do not specify this attribute, the external loader determines an optimal splitting method.
Mode	Split and load	Loading mode the external loader uses to load the data. Select one of the following loading modes: Split and load Split only Load only Analyze
Max Num Splitters	25	Maximum number of splitter processes.
Force	No	Forces the external loader operation to continue even if it determines at startup time that some target partitions or tablespaces are offline.
Status Interval	100	Number of megabytes of data the external loader loads before writing a progress message to the external loader log. Specify a value between 1 and 4,000 MB.
Ports	6000-6063	Range of TCP ports the external loader uses to create sockets for internal communications with the IBM DB2 server.
Check Level	Nocheck	Checks for record truncation during input or output.
Map File Input	n/a	Name of the file that specifies the partitioning map. To use a customized partitioning map, specify this attribute. Generate a customized partitioning map when you run the external loader in Analyze loading mode.
Map File Output	n/a	Name of the partitioning map when you run the external loader in Analyze loading mode. You must specify this attribute if you want to run the external loader in Analyze loading mode.
Trace	0	Number of rows the external loader traces when you need to review a dump of the data conversion process and output of hashing values.
Is Staged	Disabled	Method of loading data. Select Is Staged to load data to a flat file staging area before loading to the database. Otherwise, the data is loaded to the database using a named pipe.
Date Format	mm/dd/yyyy	Date format. Must match the date format you define in the target definition. IBM DB2 supports the following date formats: MM/DD/YYYY YYYY-MM-DD DD.MM.YYYY YYYY-MM-DD
