Pivotal Cloud Cache Release Notes

v1.6.2

Release Date: April 10, 2019

Features included in this release:

Breaking Change: This patch release increases system security by requiring TLS encryption for using gfsh and Pulse. Follow the steps within Preparing for TLS prior to installing the PCC tile.
WARNING: Follow the procedure detailed in Special Upgrade Procedure for Dev and Small Footprint Plans when upgrading to PCC v1.6.2 for plans that colocate system components on a single VM. This applies to the dev plan and to the small footprint plan.
If a ClamAV or File Integrity Monitor is detected, available memory for GemFire servers is reduced to allow enough memory for these PCF add-ons. This prevents a failure during PCC service instance creation.
Multiple PCC service instances are now spread across availability zones.
Increased the operating system limit for the number of files that can be open concurrently.
PCC uses Pivotal GemFire 9.6.1.

Installations using HTTP session state replication have a known issue issue and workaround to correct the issue. The HTTP session module creates its region that holds metadata on only one server within a cluster. The region needs to be hosted on all the servers.

To correct the issue on a running cluster, connect to the cluster using the GemFire cluster operator credentials, and run a single gfsh command to create the metadata region on all servers. The command has the form:
```
create region --name=REGION-NAME --type=REGION-SHORTCUT \
 --enable-statistics \
 --entry-idle-time-custom-expiry=org.apache.geode.modules.util.SessionCustomExpiry
```
If the metadata region’s name or type have not been changed from their default, use this gfsh command:
```
gfsh>create region --name=gemfire_modules_sessions --type=PARTITION_REDUNDANT \
 --enable-statistics \
 --entry-idle-time-custom-expiry=org.apache.geode.modules.util.SessionCustomExpiry
```
For installations that have changed the metadata region’s name or type, substitute the changed values for REGION-NAME and REGION-SHORTCUT in the command.

You can verify that the region is hosted on all servers with the gfsh command:
```
gfsh>describe region --name=gemfire_modules_sessions
```
Current versions of the Cloud Foundry Command Line Interface (CLI) tool have a known bug that omits the documentation URL when using the cf service command.
