IBM DB2 on iSeries/AS400

The IBM DB2 Connection is available for databases on iSeries/AS400, which is discussed on this IBM Knowledge Center page.

Prerequisites

DB2 running on iSeries/AS400 mainframe (min version tested v7.4)
Network connectivity
Hostname or IP address
Port Number (SSL or non-SSL)
Database name
Database access credentials

Connection Properties

The following table describes the fields available when creating a new IBM DB2 Connection. Create a connection using the information below and these step-by-step instructions.

Field	Required	Description
Access Type	Required	The type of connection for DB2 on AS400 is Read-Only.
Host	Required	IP or the hostname of the DB2 server.
Port	Optional	Host server port number. The default port number for DB2 on iSeries/AS400 is 8471 (non-SSL) or port 9471 (SSL). Reference: IBM Toolbox for Java.
Database Name	Required	The database name you are connecting to.
Custom Connection Properties	Optional	Properties specified when connecting to DB2. See Properties for DB2 on AS400 using JDBC below for Ascend specific formatting.
Requires Credentials	Optional	Choose from existing credentials or create new credential for connecting to DB2 Database on AS400 if 'Requires Credentials' checkbox is selected.

Custom Connection Properties

Ascend utilizes JDBC to connect to IBM DB2 on iSeries/AS400 which allows for many property specifications. The names of keys and values can be found in the IBM Toolbox for Java JDBC properties documentation.

Ascend specific formatting

To specify properties in Ascend, do not use quotations. Present each property as newline-delimited key=value pairs (see Figure 3 below for an example).

Credential Properties

The following table describes the fields available when creating a new IBM DB2 credential.

Field	Required	Description
Credential Name	Required	The name to identify this credential with. This credential will be available as a selection for future use.
Credential Type	Required	This field will automatically populate with DB2 on AS400.
User	Required	The DB2 username to connect with.
Password	Required	The DB2 password to connect with.

Read Connector Properties

The following table describes the fields available when creating a new IBM DB2 Read Connector.

Field	Required	Description
Name	Required	Provide a name for your connector. We recommend using lowercase with underscores in place of spaces.
Description	Optional	Describes the connector. We recommend providing a description if you are ingesting information from the same source twice, for different reasons.
Table Name	Required	Name of the table being ingested. This can either be supplied manually or selected in Step 2.
Schema Name	Optional	If using a specific schema configuration, provide a name.

Write Connector Properties

The following table describes the fields available when creating a new IBM DB2 Write Connector. Create a new Write Connector using the information below and these step-by-step instructions.

Field Name	Required	Description
Name	Required	Provide a name for your connector. We recommend using lowercase with underscores in place of spaces.
Description	Optional	Describes the connector. We recommend providing a description if you are ingesting information from the same source multiple times for different reasons.
Upstream	Required	The name of the previous connector the Write Connector will pull data from.
Table Name	Required	The name of the table that will be written to the DB2 database.
Write Strategy	Required	The strategy to copy data into the DB2 database. The Full Load strategy will replace the entire table's contents each time that the upstream transform has changed. If the upstream data set contains multiple Ascend partitions and not all partitions are expected to change on each update, then the Incremental By Partition strategy allows for Ascend to only update/insert/delete the partitions of the Amazon Redshift table that have changed in Ascend.
Max Number of Parallel Ascend Partitions	Optional	Ascend can write partitions in parallel. Ex.: If a transform has 2000 partitions and you set the max parallel to 100, Ascend will write partitions 100 at a time.
A SQL Statement for Ascend to Execute Before Writing	Optional	Executes a pre-processing script before writing to final table.
A SQL Statement for Ascend to Execute After Writing	Optional	Executes a pre-processing script after writing to final table.
Schema Name	Optional	The name of the schema to match.
On Schema Mismatch	Optional	Options are as follows: - Skip schema check - Stop and display error - Recreate table - Alter table
Column Type Overrides	Optional	Specify data types overrides (e.g: "name CHAR(64), comments VARCHAR(1024)") where the column name is followed by the data type and each pair is separated by a comma.
