B.4 Engine Control Values

The engine control values are a means through which certain default behaviors of the Metadirectory engine can be changed. The values can only be accessed if a server is associated with the Driver Set object.

In iManager:

  1. Click Identity Manager > Identity Manager Overview.

  2. Click Search to search for the driver set that is associated with the driver.

  3. Click the upper right corner of the driver icon.

  4. Click Edit Properties > Engine Control Values.

In Designer:

  1. In the Modeler, right-click a driver line.

  2. Select Properties > Engine Control Values.

  3. Click the tooltip icon to the right of the Engine Controls for Server field. If a server is associated with the Identity Vault, the Engine Control Values display in the large pane.

Table B-7 Engine Control Values

Option

Description

Subscriber channel retry interval in seconds

The Subscriber channel retry interval controls how frequently the Metadirectory engine retries the processing of a cached transaction after the application shim's Subscriber object returns a retry status.

Qualified form for DN-syntax attribute values

The qualified specification for DN-syntax attribute values controls whether values for DN-syntax attribute values are presented in unqualified slash form or qualified slash form. A True setting means the values are presented in qualified form.

Qualified form from rename events

The qualified form for rename events controls whether the new-name portion of rename events coming from the Identity Vault are presented to the Subscriber channel with type qualifiers. For example, CN=. A True setting means the names are presented in qualified form.

Maximum eDirectory replication wait time in seconds

This setting controls the maximum time that the Metadirectory engine waits for a particular change to replicate between the local replica and a remote replica. This only affects operations where the Metadirectory engine is required to contact a remote eDirectory server in the same tree to perform an operation and might need to wait until some change has replicated to or from the remote server before the operation can be completed (for example, object moves when the Identity Manager server does not hold the master replica of the moved object; file system rights operations for Users created from a template.)

Use non-compliant backwards-compatible mode for XSLT

This control sets the XSLT processor used by the Metadirectory engine to a backwards-compatible mode. The backward-compatible mode causes the XSLT processor to use one or more behaviors that are not XPath 1.0 and XSLT 1.0 standards-compliant. This is done in the interest of backward compatibility with existing DirXML® style sheets that depend on the non-standard behaviors.

For example, the behavior of the XPath “!=” operator when one operand is a node-set and the other operand is other than a node-set is incorrect in DirXML releases up to and including Identity Manager 2.0. This behavior has been corrected; however, the corrected behavior is disabled by default through this control in favor of backward compatibility with existing DirXML style sheets.

Maximum application objects to migrate at once

This control is used to limit the number of application objects that the Metadirectory engine requests from an application during a single query that is performed as part of a Migrate Objects from Application operation.

If java.lang.OutOfMemoryError errors are encountered during a Migrate from Application operation, this number should be set lower than the default. The default is 50.

NOTE:This control does not limit the number of application objects that can be migrated; it merely limits the batch size.

Set creatorsName on objects created in Identity Vault

This control is used by the Identity Manager engine to determine if the creatorsName attribute should be set to the DN of this driver on all objects created in the Identity Vault by this driver.

Setting the creatorsName attribute allows for easily identifying objects created by this driver, but also carries a performance penalty. If not set, the creatorsName attribute defaults to the DN of the NCP™ Server object that is hosting the driver.

Write pending associations

This control determines whether the Identity Manager engine writes a pending association on an object during Subscriber channel processing.

Writing a pending association confers little or no benefit but does incur a performance penalty. Nevertheless, the option exists to turn it on for backward compatibility.

Use password event values

This control determines the source of the value reported for the nspmDistributionPassword attribute for Subscriber channel Add and Modify events.

Setting the control to False means that the current value of the nspmDistributionPassword is obtained and reported as the value of the attribute event. This means that only the current password value is available. This is the default behavior.

Setting the control to True means that the value recorded with the eDirectory event is decrypted and is reported as the value of the attribute event. This means that both the old password value (if it exists) and the replacement password value at the time of the event are available. This is useful for synchronizing passwords to certain applications that require the old password to enable setting a new password.

Enable password synchronization status reporting

This control determines whether the Identity Manager engine reports the status of Subscriber channel password change events.

Reporting the status of Subscriber channel password change events allows applications such as the Identity Manager User Application to monitor the synchronization progress of a password change that should be synchronized to the connected application.
