Pivotal GemFire Release Notes
Pivotal GemFire 9.5 is based on Apache Geode version 1.6. Pivotal GemFire 9.5 and Apache Geode share a common set of documentation. Therefore, references to both GemFire and Apache Geode appear throughout this documentation; consider them equivalents.
Pivotal GemFire 9.5 includes the following improvements:
New gfsh commands work with JNDI bindings:
gfsh describe jndi-binding
gfsh destroy jndi-binding
gfsh list jndi-binding
Three new attributes on the gateway sender MBean monitor events that are overflowed to disk:
The GemFire-Greenplum Connector is now incorporated into the GemFire release, eliminating the need for a separate download of the connector JAR file. The connector JAR file is automatically included in the classpath, thereby simplifying member startup.
load-cluster-configuration-from-diroption of the
gfsh start locatorcommand is deprecated.
You can download Pivotal GemFire 9.5 from the Pivotal GemFire product download page.
For details on how to install Pivotal GemFire 9.5, see Installing Pivotal GemFire.
Note that the file name extension for the compressed TAR file is
.tar.gz (rather than
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
geode.disallow-internal-messages-without-credentials system property set to
gfsh>start server --name=server_name --dir=server_config_dir \ --J=-Dgeode.disallow-internal-messages-without-credentials=true
The GemFire 9.5 release is based on the Apache Geode 1.6 release. This section describes issue resolutions that significantly affect GemFire applications. For a list of all issues resolved in Geode 1.6, see the Geode 1.6 Release Notes.
The following issues have been resolved in GemFire 9.5. Ticket numbers of the form GEODE‑NNNN can be inspected at the Apache Software Foundation site for Geode issues.
GEODE-2321: Fixed Pulse to work correctly in locales other than the US.
GEODE-3456, GEM-1917: Fixed a bug that caused Pulse to display a nonexistent cluster.
GEODE-3891, GEM-1777: Fixed an issue that prevented the ability to set specific ciphers for the REST interface.
GEODE-3922: Corrected the Pulse help tab link.
GEODE-4451: Fixed a bug which left a gateway sender in
an unusable state when authentication failed between
the sender and receiver.
Now an authentication exception is thrown, and,
similar to an
the gateway sender will continue to retry the connection
while the sender queue grows until either authentication
succeeds or the operator destroys the sender.
GEODE-4475, GEM-1677: Eliminated displaying some JVM arguments.
GEODE-4497: Fixed a gfsh output text wrapping error.
GEODE-4755: Fixed a bug that prevented deploying JAR files on Windows platforms.
GEODE-4765, GEM-1918: Fixed an issue in which cluster configuration did not respond after a locator reconnected to the distributed system.
GEODE-4769: Region entries are now serialized before putting them in a local cache.
GEODE-4771, GEM-1929: Corrected the implementation
gfsh configure pdx with the
check-portability attribute is now false.
GEODE-4823, GEM-1936: Prevent tombstones from being added to an index during region initialization to avoid a lengthy initialization period.
GEODE-4840: Fixed a bug in honoring
pdx-read-serialized=false property that
manifested itself as an incorrect attempt to deserialize an instance
PdxInstance class was not on the classpath.
GEODE-4867, GEM-1958: Ensure that the
system variable is honored during long queries to avoid
hitting an out of memory exception.
GEODE-4893, GEM-1974: Fixed a
gfsh import cluster-configuration bug
that inadvertently shut down a server.
GEODE-4902, GEM-1942: Fixed a bug that prevented logging markers.
GEODE-4928, GEM-1487: Fixed a timing issue in transaction locking that manifested as a commit conflict after a server crash.
GEODE-4930: Implemented feature flagging for gfsh commands.
GEODE-4933: Entry expiration now updates the last accessed time on proxy (normal) or local (preloaded) replicated regions.
GEODE-4957: Fixed a race condition
that existed when there were concurrent create entry operations in progress.
The race condition could cause a
to return null when the entry exists.
GEODE-4960, GEM-1965: Fixed a bug that prevented deploying JAR files
when SSL was enabled.
ConnectIOException appeared in the output.
GEODE-5039: Fixed a bug that prevented
an invocation of
EvictionAttributesMutator.setMaximum from setting
the maximum number of events.
GEODE-5085, GEM-2010: Fixed a bug that caused
AuthenticationRequiredException upon an autoreconnect
of a server.
The following known issues affect GemFire 9.5:
GEM-1197: If the initialization of a Spring container is not complete upon the start or restart of an embedded locator, deadlock can result. Avoid this issue by completing Spring container initialization before starting locators or servers; start GemFire processes in the Spring container’s startup event.
GEM-2009: A race condition exists that can cause a hang
in the execution of a region set operation
The race exists when clients that are GemFire version 9.2
or earlier run with servers that are GemFire 9.3.0 or later
and the region set operation is the first operation within a transaction.
To avoid this race condition,
set the system property
