Pivotal GemFire Release Notes

Pivotal GemFire 9.6 is based on Apache Geode version 1.7. Pivotal GemFire 9.6 and Apache Geode share a common set of documentation. Therefore, references to both GemFire and Apache Geode appear throughout this documentation; consider them equivalents.

For more information on issues resolved in GemFire v9.6.2, see Issues Resolved in Pivotal GemFire 9.6.2.

What’s New in Pivotal GemFire 9.6

Pivotal GemFire 9.6 includes the following improvements:

  • A pair of new gfsh commands were added in support of cluster configuration: import cluster-configuration and export cluster-configuration.

This Pivotal GemFire 9.6 release includes GemFire-Greenplum Connecter version 3.3. See the GemFire-Greenplum Connecter Release Notes for details.

Installing Pivotal GemFire 9.6

You can download Pivotal GemFire 9.6 from the Pivotal GemFire product download page.

For details on how to install Pivotal GemFire 9.6, see Installing Pivotal GemFire.

Note that the file name extension for the compressed TAR file is .tar.gz (rather than .tgz).

Upgrading to Pivotal GemFire 9.6

To upgrade from an earlier version of GemFire to the current version, see Upgrading Pivotal GemFire.

When servers are upgraded to this GemFire version from a version prior to version 9.1.1, their authentication of client messages is disabled in order to facilitate rolling upgrades. If your clients are set up to send authenticated messages, the servers will honor those messages, but will not enforce authentication until you reinstate authentication on each of the upgraded servers.

To reinstate secure client/server messaging, restart each server with the geode.disallow-internal-messages-without-credentials system property set to true. For example:

gfsh>start server --name=server_name --dir=server_config_dir \

Resolved Issues

The GemFire 9.6 release is based on the Apache Geode 1.7 release. This section describes issue resolutions that significantly affect GemFire applications. For a list of all issues resolved in Geode 1.7, see the Geode 1.7 Release Notes. Ticket numbers of the form GEODE‑NNNN can be inspected at the Apache Software Foundation site for Geode issues.

Issues Resolved in Pivotal GemFire 9.6.2

GEODE-3649: Initialize the PDX registry before attempting an auto-reconnect.

GEODE-3948: Ensure that client/server connection read timeout is honored.

GEODE-6244: Fixed a case in which a slowly responding member could mistakenly initiate the disconnection of a better-responding member.

GEODE-6271, GEM-2356: Improved support of clients connected to multiple distributed systems by copying serialized types between clusters.

GEODE-6309, GEODE-6363: A restarting locator tries harder to find an existing cluster coordinator before assuming the role itself.

GEODE-6369: Terminate auto-reconnect attempts if reconnect is not possible.

GEODE-6423, GEM-2410: The availability check following a network outage honors the member timeout setting before disconnecting.

GEODE-6451, GEODE-6522: Fixed a membership issue that could cause the server to hang during shutdown.

Issues Resolved in Pivotal GemFire 9.6.1

GEODE-92: Fixed a bug in which custom expiry code that called getValue() could cause a deadlock that resulted in no region operations completing. The previous fix for GEODE-92 did not cover all possibilities.

GEODE-5747, GEODE-6065: Improved the WAN gateway sender’s resilience in the face of intermittent DNS failures or unexpected socket resets in the underlying operating system.

GEODE-6177: Improved the gateway sender’s ability to re-authenticate upon reconnection following a dropped WAN connection.

GEODE-6215, GEM-2341: Fixed a bug with the HTTP session store that resulted in the session region not being created on all servers.

GEODE-6267, GEODE-6287, GEM-2352: Fixed server side memory leaks that occurred during client departure.

GEODE-6328, GEODE-6329, GEM-2376: Fixed issues with the gfsh show missing-disk-stores command, in which the command listed instances that were not missing or duplicate entries.

GEODE-6344, GEM-2365: Fixed a source of spurious “socket read timeout” exceptions on client proxy reconnection requests by replacing existing proxies with new instances.

GEODE-5649, GEM-2203: Fixed an inconsistency in the performance of getAll() operations across multiple members

Issues Resolved in Pivotal GemFire 9.6.0

GEODE-4218: In the gfsh start locator command, the deprecated load-cluster-configuration-from-dir option is no longer required when setting --cluster-config-dir.

GEODE-4990, GEM-1991: Fixed a bug that could lead to a null-pointer error (NPE) when starting a server if the cluster configuration service is enabled and the locator hasn’t finished the startup.

GEODE-5157, GEM-2167, GEM-2168, GEM-2169: Fixed a bug that sometimes prevented ClientHealthStats from being propagated when the system has a hostname.

GEODE-5194: Allow gfsh clients with different patch versions to connect to a the same locator.

GEODE-5204: Add import cluster-configuration and export cluster-configuration gfsh commands.

GEODE-5220, GEM-1938: Fixed a bug that could leave a replicated region in an inconsistent state during creation when a parallel async-event-queue or gateway-sender is assigned to it.

GEODE-5230: Fixed a bug that resulted in broken Pulse functionality when SSL was enabled for JMX access.

GEODE-5247: Fixed a bug that resulted in some gfsh data commands displaying an object reference instead of a proper JSON object when returning nested objects.

GEODE-5256, GEM-2076: Parameters passed to the gfsh start server command now take precedence over defaults and values specified in cache.xml configurations.

GEODE-5433, GEM-2151: Fixed a bug that allowed OQL indexes to retrieve stale data while a region GII update is in progress.

GEODE-5478, GEM-2165: Fixed a bug that caused the lowRedundancyBucketCount statistic not to be maintained properly when multiple members are stopped and restarted.

GEODE-5534: Fixed a bug that could lead to increased memory usage when PDX values are stored and compression is enabled.

GEODE-5571, GEM-2176: Pulse now shows all data queries, including failed ones.

GEODE-5618, GEM-2206: Fixed a bug that prevented clients with multiuser-authentication enabled from executing functions on particular servers or regions.

GEODE-5631, GEM-2195: Fixed a bug that could lead to increased memory footprint when using asynchronous event listeners.

GEODE-5646, GEM-2188: Fixed an error in client locator communications that could occur when a locator is shutting down.

GEM-2228 Fixed a problem that could cause data inconsistencies between WAN sites with serial gateway senders and multiple writers when operations were applied out of order.


General support includes security vulnerability resolutions and critical bug fixes in all supported minor versions, while other maintenance is applied only to the latest supported minor release.
