Pivotal GemFire 9.0 Release Notes
Pivotal GemFire 9.0 provides all the benefits of open source software, as it is based on the Apache Geode 1.0.0-incubating release. It also includes fixes from later Apache Geode releases. Pivotal GemFire 9.0 and Apache Geode share a common set of documentation. Therefore, references to both GemFire and Apache Geode appear throughout this documentation; consider them equivalents.
Region values may be stored in off heap memory, instead of heap memory. Off heap memory is not subject to Java garbage collection, leading to performance advantages for some applications. See Managing Off-Heap Memory for details.
The new Integrated Security feature provides a simpler and more powerful way of doing authentication and authorization. See Security for details. Users of GemFire 8.x should strongly consider reimplementing system-wide security measures under the new method, especially since the 8.x Authenticator and AccessControl APIs have been superseded by the new interface. The 8.x implementation is supported, but is now deprecated. If any 9.0 integrated security properties are specified (such as
security-manager), GemFire will not honor the 8.x configuration and the entire app must migrate to the 9.0 scheme.
A new scheme for configuring SSL is both simpler and more powerful than its predecessor. The older SSL configuration scheme used separate, single-valued properties with component-specific prefixes such as
server-. The new configuration scheme uses a simpler naming scheme in which a smaller number of properties using the
ssl-prefix can take multiple values. See SSL for details.
The older SSL scheme is supported, but is now deprecated. If any new-style properties are specified (those with the
ssl-prefix), then GemFire will not honor the older configuration, and the entire app must migrate to the new scheme.
The pre-GemFire 8.x SSL scheme, formerly deprecated, is now unsupported.
All member discovery is through locators. Multicast communication can no longer be used for discovery.
Due to licensing restrictions with Apache Software Foundation, the JGroups implementation used in Pivotal GemFire has been replaced and updated to a compatible version. This also allows GemFire to deal with JGroups as an external dependency and keep up with recent versions as needed.
Tomcat version 8 is now supported for HTTP session management.
The Visual Statistics Display (VSD) utility is no longer included in the Gemfire installation. VSD is available for download from the Pivotal GemFire download page.
An adapter that allows GemFire to function as a drop-in replacement for a Redis data store is available in an experimental implementation. See Experimental Features to read about this feature.
OQL aggregate functions are available in an experimental implementation. See Experimental Features to read about this feature.
An experimental implementation does a rebalance operation on a periodic basis, basing a decision to do the rebalance on a minimum quantity of bytes that would be transferred and/or on the ratio of the bytes that would be transferred to the total number of bytes stored. See Experimental Features to read about this automated rebalance feature.
An experimental implementation allows the creation of Apache Lucene indexes on data stored in GemFire.

The following issues have been resolved in GemFire 9.0.4. Ticket numbers of the form GEODE-NNNN can be inspected at the Apache Software Foundation site for Geode issues.
GEODE-1971/GEM-983: Fixed a
shutDownAllhang that was caused by a new member joining while the shutdown was in progress.
GEODE-2155: Improved reliability of auto-reconnect by terminating attempts to reconnect when cache.xml is invalid.
GEODE-2193: Fixed a problem in which a membership request was denied if it was received during a membership coordinator transition.
GEODE-2642: Fixed a race condition that sometimes caused a client to skip a scheduled ping of the server.

jmx-manager-portsetting on locator start up when trying to connect to the locator.
GEODE-2732: Auto-reconnect now honors a gfsh command-line request for restarting a server on a non-default port.
GEODE-2756: Ensured that security-related properties are not visible in environment variables or log files.
GEODE-2764: Added checks on new region names to prune any function calls that appear in the name string.
GEODE-2775: Corrected setting of the Pulse SSL Manager flag from System properties instead of
pulse.propertieswhen running in embedded mode.

ArrayIndexOutOfBoundsExceptionthat could occur when performing a disk store backup.
GEODE-2808/GEM-1380: Fixed lock ordering issues that sometimes resulted in deadlocks during session expiration.

- GEODE-2670: Updated the authorization implementation, restricting data access via Pulse, to address CVE-2017-5649.
The following issues have been resolved in GemFire 9.0.2. Ticket numbers of the form GEODE-NNNN can be inspected at the Apache Software Foundation site for Geode issues.
GEODE-1272/GEM-1133: The index creation operation now correctly handles exceptions and does not deserialize PDX objects.
GEODE-1969/GEM-1243: An IOException will no longer occur due to an oplog closure when the gemfire.syncWrites property is true.
GEODE-2129: A hash of the pdxType reduces collisions on the identifiers.
GEODE-2174/GEM-778: Improved the server’s logging of client unregistration details.
GEODE-2179/GEODE-2186/GEM-1104: The gateway sender status displayed in Pulse has been corrected.

GEODE-2213: A fix eliminates a potential deadlock upon a connection request of a new member.
GEODE-2215: Eliminates an erroneous null pointer exception from the view creator.
GEODE-2216/GEM-1133: Failure to create an index on one of a set of nodes resulted in an unpopulated index which returned incorrect results for queries.
GEODE-2224/GEM-1123: The local QueryService no longer throws an exception when running a query within a transaction.
GEODE-2228: Fixed a bug that caused a transaction to hang, when the member that grants locks changes during the transaction.
GEODE-2242: Fixed a bug that caused destroy operations on preloaded regions to not be applied in a receiving WAN site.
gfsh export logscommand has been improved to send all logs to the locator’s file system when communication is over JMX. When the command is sent via an HTTP request, the logs are sent to the requester, and the temporary copy is deleted.
