IMS Connection Properties

IMS Connection Properties

Use an IMS connection to access an IMS database. The IMS connection is a non-relational mainframe database type connection. The Data Integration Service connects to IMS through PowerExchange. You create an IMS connection in the Developer tool. You can manage an IMS connection in the Administrator tool or the Developer tool.
The following table describes IMS connection properties:
Option
Description
Location
Node name for the location of the PowerExchange Listener that connects to IMS. The node name is defined in the first parameter of the NODE statement in the PowerExchange dbmover.cfg configuration file.
User name
Database user name.
Password
Password for the specified database user name or a valid PowerExchange passphrase.
A PowerExchange passphrase can be from 9 to 128 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.
The allowable characters in the IBM IRRPHREX exit do not affect the allowable characters in PowerExchange passphrases.
A valid RACF passphrase can be up to 100 characters in length. PowerExchange truncates passphrases longer than 100 characters when passing them to RACF for validation.
To use passphrases for IMS connections, ensure that the following requirements are met:
  • The PowerExchange Listener must run 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
    .
  • You must configure ODBA access to IMS as described in the
    PowerExchange Navigator User Guide
    .
  • You must use IMS data maps that specify IMS ODBA as the access method. Do not use data maps that specify the DL/1 BATCH access method because this access method requires the use of netport jobs, which do not support passphrases.
  • The IMS database must be online in the IMS control region to use ODBA access to IMS.
Code page
Required. Name of the code page to use for reading from or writing to the data source. Usually, this value is an ISO code page name, such as ISO-8859-6.
Pass-through security enabled
Enables pass-through security for the connection.
Encryption type
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
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.
Offload processing
Optional. Controls whether to offload some bulk data processing from the source machine to the Data Integration Service machine. Select one of the following options:
  • AUTO
    . The Data Integration Service determines whether to use offload processing.
  • Yes
    . Use offload processing.
  • No
    . Do not use offload processing.
Default is AUTO.
Worker threads
Optional. Number of threads that the Data Integration Service uses to process bulk data when offload processing is enabled. For optimal performance, this value should not exceed the number of available processors on the Data Integration Service machine. Valid values are 1 through 64. Default is 0, which disables multithreading.
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 1 to 5000. Default is 25.
Write mode
Optional. Mode in which 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
.
