DB2 for i5/OS

. An IBM DB2 for i5/OS connection is a relational database connection. You can create and manage an IBM DB2 for i5/OS connection in the Administrator tool or the Developer tool.

The order of the connection properties might vary depending on the tool where you view them.

The following table describes DB2 for i5/OS connection properties:

Property	Description
Name	Name of the connection. The name is not case sensitive and must be unique within the domain. The name cannot exceed 128 characters, contain spaces, or contain the following special characters: ~ ` ! $ % ^ & * ( ) - + = { [ } ] \| \ : ; " ' < , > . ? /
ID	String that the Data Integration Service uses to identify the connection. The ID is not case sensitive. It must be 255 characters or less and must be unique in the domain. You cannot change this property after you create the connection. Default value is the connection name.
Description	The description of the connection. The description cannot exceed 255 characters.
Connection Type	The connection type (DB2I).
Username	A database user name.
Password	A password for the specified user name or a valid PowerExchange passphrase. A PowerExchange passphrase can be from 9 to 31 characters in length and can contain the following characters: Uppercase and lowercase letters The numbers 0 to 9 Spaces The following special characters: ’ - ; # \ , . / ! % & * ( ) _ + { } : @ \| < > ? The first character is an apostrophe. Passphrases cannot include single quotation marks (‘), double quotation marks (“), or currency symbols. To use passphrases, ensure that the PowerExchange Listener runs with a security setting of SECURITY=(1,N) or higher in the DBMOVER member. For more information, see "SECURITY Statement" in the PowerExchange Reference Manual .
Pass-through security enabled	Enables pass-through security for the connection.
Database name	The database instance name.
Location	Node name for the location of the PowerExchange Listener that connects to DB2. The node name is defined in the first parameter of the NODE statement in the PowerExchange dbmover.cfg configuration file.
Environment SQL	SQL commands to set the database environment when you connect to the database. The Data Integration Service executes the connection environment SQL each time it connects to the database.
Database file overrides	Specifies the i5/OS database file override in the following format: from_file/to_library/to_file/to_member Where: from_file is the file to be overridden. to_library is the new library to use. to_file is the file in the new library to use. to_member is optional and is the member in the new library and file to use. *FIRST is used if nothing is specified. You can specify up to eight unique file overrides on a single connection. A single override applies to a single source or target. When you specify more than one file override, enclose the string of file overrides in double quotes (") and include a space between each file override. If you specify both Library List and Database File Overrides and a table exists in both, the Database File Overrides value takes precedence.
Library list	List of libraries that PowerExchange searches to qualify the table name for Select, Insert, Delete, or Update statements. PowerExchange searches the list if the table name is unqualified. Separate libraries with commas. If you specify both Library List and Database File Overrides and a table exists in both, the Database File Overrides value takes precedence.
Code Page	The code page used to read from a source database or write to a target database or file.
SQL Identifier character to use	Type of character that the database uses to enclose delimited identifiers in SQL queries. The available characters depend on the database type. Select (None) if the database uses regular identifiers. When the Data Integration Service generates SQL queries, the service does not place delimited characters around any identifiers. Select a character if the database uses delimited identifiers. When the Data Integration Service generates SQL queries, the service encloses delimited identifiers within this character.
Support mixed case identifiers	Enable if the database uses case-sensitive identifiers. When enabled, the Data Integration Service encloses all identifiers within the character selected for the SQL Identifier Character property. When the SQL Identifier Character property is set to none, the Support Mixed-case Identifiers property is disabled.
Isolation level	Commit scope of the transaction. Select one of the following options: None CS . Cursor stability. RR . Repeatable Read. CHG . Change. ALL Default is CS.
Encryption type	Optional. The type of encryption that the Data Integration Service uses. Select one of the following options: None AES Default is None. Informatica recommends that you use Secure Sockets Layer (SSL) authentication instead of configuring the Encryption type and Encryption level connection properties. SSL authentication provides stricter security and is used by several Informatica products. For more information about implementing SSL authentication in a PowerExchange network, see the PowerExchange Reference Manual .
Encryption level	If you select AES for Encryption Type , select one of the following options to indicate the encryption level that the Data Integration Service uses: 1 . Use a128-bit encryption key. 2 . Use a 192-bit encryption key. 3 . Use a 256-bit encryption key. If you do not select AES for Encryption Type , this option is ignored. Default is 1.
Pacing size	Optional. Amount of data that the source system can pass to the PowerExchange Listener. Set the pacing size if an external application, database, or the Data Integration Service node is a bottleneck. User lower values for faster performance. The minimum value and default value is 0. A value of 0 provides the best performance.
Interpret as rows	Optional. Select this option to express the pacing size as a number of rows. Clear this option to express the pacing size in kilobytes. By default, this option is not selected and the pacing size is in kilobytes.
Compression	Optional. Select this option to enable source data compression. By compressing data, you can decrease the amount of data that Informatica applications send over the network. By default, this option is not selected and compression is disabled.
Array size	Optional. The number of records in the storage array for the worker threads. This option is applicable when you set the Worker Threads option to a value greater than 0. Valid values are 25 to 5000. Default is 25.
Write mode	Optional. Mode in which the Data Integration Service sends data to the PowerExchange Listener. Select one of the following write modes: CONFIRMWRITEON . Sends data to the PowerExchange Listener and waits for a response before sending more data. Select this option when error recovery is a priority. However, this option might degrade performance. CONFIRMWRITEOFF . Sends data to the PowerExchange Listener without waiting for a response. Use this option if you can reload the target table when an error occurs. ASYNCHRONOUSWITHFAULTTOLERANCE . Sends data to the PowerExchange Listener without waiting for a response. This option also enables error detection. This option combines the speed of CONFIRMWRITEOFF and the data integrity of CONFIRMWRITEON. Default is CONFIRMWRITEON .
Reject file	Overrides the default prefix of PWXR for the reject file. PowerExchange creates the reject file on the target machine when the write mode is ASYNCHRONOUSWITHFAULTTOLERANCE. Enter PWXDISABLE to prevent the creation of the reject files.
