max-interactions-per-snapshot

Section: settings
Default Value: 500
Valid Values: Any integer from 100 to 2,000
Changes Take Effect: Immediately


Specifies the maximum number of interactions that clients can select in a snapshot.

internal-interactions-sorting

Section: settings
Default Value: true
Valid Values: true, false, yes, no
Changes Take Effect: Immediately


Specifies if Interaction Server Proxy should use internal sorting mechanism while merging responses containing multiple interactions in given order from multiple nodes. This option applies to: RequestTakeSnapshot, RequestGetSnapshotInteractions, RequestFindInteractions, RequestGetWorkbinContent. After change it applies to newly sent requests, i.e. already taken snapshot won't be affected (only option is to re-take same snapshot). It's adviced to restart Interaction Server Proxy after changing this value.

List of Release Notes

What's New

This release contains the following new features and enhancements:

  • Interaction Server Proxy working with an Interaction Server Cluster can now deliver a list of interactions properly sorted according to the attribute Order as set in such requests as RequestFindInteraction, RequestGetWorkbinContent, and RequestTakeSnapshot (RequestGetSnapshotInteractions delivers the actual list).
    This functionality is controlled by the new configuration option internal-interactions-sorting.
  • This release introduces the option internal-interactions-sorting (in the settings section), which specifies whether Interaction Server Proxy uses its internal sorting mechanism when merging responses containing multiple interactions from multiple nodes.
    Note: The Proxy’s internal mechanism sorts the results according to the binary representation of the character strings (specifically using the function strcmp). This method of sorting may not give the same results as the database sorting, which uses collation tables for a specific language (set for the specific database) when it sorts character data.
  • This release introduces the option max-interactions-per-snapshot (in the settings section). The option specifies the maximum number of interactions that clients can select in a snapshot. In a cluster configuration, the Proxy forwards RequestTakeSnapshot to every node in the cluster either specifying the limit for number of interactions provided in the original request from the client or specifying the maximum configured by 'max-interactions-per-snapshot' option. It then merges the results from all the nodes and returns number of interactions up to the specified (or configured) limit. This logic provides the global ordering among all the nodes. The side effect is that if snapshot was taken with a lock, many interactions that are not accessible to the client that requested the snapshot, may be locked until the snapshot is released.

Resolved Issues

This release contains the following resolved issues:


RequestGetSnapshotInteractions now includes the correct snapshot_id when the Proxy is connected to only one Interaction Server. (ESR-12272)


Notifications are now correct after an Interaction Server node restarts or switches over. Previously, the Agent Desktop might start to receive two similar EventWorkbinContentChanged notifications instead of one on each actual content change. (ESR-12267)


This release corrects a limitation in the list of interactions in the EventHint that is sent to the Agent Desktop when Interaction Server disconnects and reconnects at a time when interactions from that Server were being handled by the Desktop.

  • Now this Event includes all interactions handled by the Desktop, regardless of the way they came, whether in response to a successful RequestPull, RequestSubmit or RequestAccept.
  • EventHint has been extended to list separately those interactions whose handling status by the Desktop was not successfully restored after the Desktop reconnected to the Interaction Server node in the Cluster. (ESR-12266)

There is an extension of the scenarios in which the Proxy uses EventHint to notify the Agent Desktop that an Interaction Server node in a cluster has disconnected: now it sends a notification if the connection is between the Desktop and a chained Proxy client. Previously, the notification only applied to connections with the Agent Application client type. (ESR-12103)


The statement of support for Red Hat Enterprise Linux 7 is no longer missing from the read_me.html and ip_description.xml files in the installation package. (ESR-11734)
