To make UM more maintainable, functionality is sometimes removed from UM. Informatica understands that this can be disruptive to users, so we try to restrict such deprecations to features that, to our knowledge, are not needed by our users. Typically the depreciation is announced prior to the functionality being removed to give users time to replace the deprecated functionality with the recommended replacement.

Informatica recommends careful reading of each version's release notes to learn which features are being deprecated. If you are upgrading across multiple versions of UM, the deprecations for all intervening versions should be examined.

If you discover that a feature is deprecated which is important to your use case, please contact Informatica Support.

Deprecations for 6.16 <-

32-bit. Support for 32-bit applications and daemons is dropped. See Eliminate 32-bit.

Deprecations for 6.15 <-

UN-DEPRECATED: Store Groups. UM version 6.13 announced the deprecation of Store Groups. This decision has been reversed. Store groups will continue to be fully supported into the future.
REMOVED: "Reduced FD" Store. In UM version 6.13.1, we announced deprecation of the "Reduced FD" Store. In version 6.15 the reduced FD functionality has been removed from the Store. This included the removal of the LevelDB database code from the Store.
DEPRECATED: Daemon Monitoring Formats. The binary daemon monitoring formats for the Store and DRO are deprecated. The JSON daemon monitoring format for the SRS is deprecated.

We currently do not plan to remove these deprecated formats, but new monitoring features will not be added to them.

Informatica recommends transitioning to the "protocol buffer" format for Store, DRO, and SRS. See Monitoring Formats.

Deprecations for 6.14 <-

DEPRECATED: "HFX" feature. This is a heavier-weight version of Hot Failover in which multiple contexts are used to receive the duplicated data streams. This provides greater flexibility on selecting different network interfaces to carry the data.

The feature turned out not to be of interest to our customers. If you use this feature, please contact Informatica Support.

See Hot Failover Across Multiple Contexts (HFX).
DEPRECATED: Enabling daemon statistics on Store and DRO using "<daemon-monitor>". The C-style binary structures format of Store and DRO daemon statistics are enabled with the "<daemon-monitor>" element.

Informatica requests users to migrate to using the UM configuration file to enable automatic monitoring with Protocol Buffer monitoring format for Store and DRO by setting monitor_format (context) to "pb".

See Monitoring UM Daemons.
DEPRECATED: Monitoring Format CSV. Prior to UM version 6.14, the only monitoring formatter available was CSV (comma-separated values).

Starting in UM 6.14, CSV is deprecated in favor of proto buffs. We do not plan to remove existing CSV functionality, and we will continue to support it in its current state. But we do not plan to enhance CSV in the future.

To take advantage of new monitoring capabilities, Informatica requests that users migrate to proto buffs.

See Monitoring Formats.
DEPRECATED: Monitoring transports UDP and SNMP.

Starting in UM 6.14, monitoring transports UDP and SNMP are deprecated in favor of LBM. We do not plan to remove existing UDP or SNMP functionality, and will continue to support them in their current states. But we do not plan to enhance UDP or SNMP in the future.

To take advantage of new monitoring capabilities, Informatica requests that users migrate to the LBM transport.
DEPRECATED: SNMP Monitoring Agent.

Starting in UM 6.14, the SNMP Monitoring Agent is deprecated in favor of MCS. We do not plan to remove existing SNMP agent functionality, and will continue to support it in its current state. But we do not plan to enhance the SNMP agent in the future.

To take advantage of new monitoring capabilities, Informatica requests that users migrate to Monitoring Collector Service (MCS).
DEPRECATED: Store web monitor.

Starting in UM 6.14, the Store Web Monitor is deprecated in favor of MCS. We do not plan to remove existing web monitor functionality, and will continue to support it in its current state. But we do not plan to enhance the web monitor in the future.

To take advantage of new monitoring capabilities, Informatica requests that users migrate to Monitoring Collector Service (MCS).
DEPRECATED: DRO web monitor.

Starting in UM 6.14, the DRO Web Monitor is deprecated in favor of MCS. We do not plan to remove existing web monitor functionality, and will continue to support it in its current state. But we do not plan to enhance the web monitor in the future.

To take advantage of new monitoring capabilities, Informatica requests that users migrate to Monitoring Collector Service (MCS).

Deprecations for 6.13.1 <-

DEPRECATED: "Datagram Acceleration" feature. This is a little-known (barely documented) experimental feature offered to a few customers. The feature turned out not to be of interest to our customers. See datagram_acceleration_functions (context).

Deprecations for 6.13 <-

DEPRECATED: "Reduced FD" Stores. The Store configuration option repository-type of "reduced-fd" is now deprecated, and will be removed from a future UM version. Users of "reduced-fd" are advised to contact Informatica Support for advice on migrating to repository type "disk".
NOT DEPRECATED: Store Groups. UM version 6.13 included a deprecation announcement of multiple Q/C groups. This feature was un-deprecated in 6.15 and will be fully supported in future releases. (At no time was the functionality removed or disabled.)
DEPRECATED: "No Cache" Stores. The Store configuration option repository-type of "no-cache" is now deprecated, and will be removed from a future UM version. Users of "no-cache" are advised to contact Informatica Support for advice on migrating to repository type "disk".
DEPRECATED: Arrival Order Delivery, No Reassembly Deprecation. The Arrival Order, Fragments Not Reassembled feature (ordered_delivery 0) is still operational but may be removed in a future release.

Users are advised to use Arrival Order, Fragments Reassembled (ordered_delivery -1) instead.
DEPRECATED: Application Headers Deprecation. The Application Headers feature is still operational but may be removed in a future release.

Users are advised to use Message Properties instead.
DEPRECATED: UM configuration attribute "application_data" and the corresponding <application-data> XML configuration element. This feature was never fully implemented, and it is now formally deprecated and may be removed in a future release.

Platform Deprecations for Daemons <-

As of UM version 6.16, no 32-bit components are supported. See Eliminate 32-bit.

As of UM version 6.13, there is a reduction in supported platforms for UM daemons.

The UM daemons are:

Starting with UM version 6.13, the daemons will only be supported on the following platforms:

Daemon	Linux 64	Windows 64	Windows 32
Persistent Store (stored)	YES	YES	no
DRO - Dynamic Routing Option (tnwgd)	YES	YES	YES
Unicast Resolver Daemon (lbmrd)	YES	YES	no
SRS - Stateful Resolution Service	YES	YES	no
UMM Ultra Messaging Manager (ummd)	YES	YES	no
ActiveMQ broker	YES	YES	no
UMDS Server (umdsd)	YES	no	no

Platforms not mentioned in the above table are not supported for the UM daemon components, including 32-bit Linux, Solaris, AIX, Darwin (MacOS) IBM Power CPUs.

Note that there is no change in support for applications. UM daemons running on the reduced set of platforms will be able to service applications running on the full range of supported platforms.

Deprecations for 6.11.1 <-

Attention: The original 6.11.1 release notes announced the deprecation of certain platforms for UM daemons, claiming that they would be discontinued in UM version 6.12. However, some users requested more time for the transition. As of UM version 6.12, these deprecated daemon platforms have not yet been removed, and are therefore still fully supported in 6.12. Starting with UM version 6.13, the UM daemons will no longer be available on certain platforms. See Platform Deprecations for Daemons.

Note: User applications will continue to be fully supported on all platforms. These deprecations only apply to UM daemon executables, such as the Store Daemon and the Dynamic Router daemon.

UM daemons will continue to be available on the following platforms:

Persistent Store daemon ("stored"): Linux 64-bit, Windows 64-bit.
UM Dynamic Router daemon ("tnwgd"): Linux 64-bit, Windows 64 and 32-bit.
UM Manager daemon ("ummd"): Linux 64-bit, Windows 64-bit.
UM Resolution daemon ("lbmrd"): Linux 64-bit, Windows 64-bit.
UM Queue Broker (ActiveMQ): Linux 64-bit, Windows 64-bit.

The planned deprecated daemon platforms are:

Solaris (X86 and Sparc)
AIX
Darwin (MacOS)
Linux 32-bit
Windows 32-bit (except Dynamic Router "tnwgd", which will continue on 32-bit)

User applications deployed on these platforms will fully interoperate with daemons running on the reduced set of platforms.

Contact Informatica Support if any of these planned deprecations interfere with your existing or planned deployments.
