Parent topic:Installing and Upgrading Greenplum
Greenplum Database 6 runs on the following operating system platforms:
- Red Hat Enterprise Linux 64-bit 8.x (as of Greenplum Database version 6.20)
- Red Hat Enterprise Linux 64-bit 7.x (See the following Note.)
- Red Hat Enterprise Linux 64-bit 6.x
- CentOS 64-bit 7.x
- CentOS 64-bit 6.x
- Ubuntu 18.04 LTS
- Oracle Linux 64-bit 7, using the Red Hat Compatible Kernel (RHCK)
Important: Significant Greenplum Database performance degradation has been observed when enabling resource group-based workload management on RedHat 6.x and CentOS 6.x systems. This issue is caused by a Linux cgroup kernel bug. This kernel bug has been fixed in CentOS 7.x and Red Hat 7.x/8.x systems.
If you use RedHat 6 and the performance with resource groups is acceptable for your use case, upgrade your kernel to version 2.6.32-696 or higher to benefit from other fixes to the cgroups implementation.
Note: For Greenplum Database that is installed on Red Hat Enterprise Linux 7.x or CentOS 7.x prior to 7.3, an operating system issue might cause Greenplum Database that is running large workloads to hang in the workload. The Greenplum Database issue is caused by Linux kernel bugs.
RHEL 7.3 and CentOS 7.3 resolves the issue.
Note: Do not install anti-virus software on Greenplum Database hosts as the software might cause extra CPU and IO load that interferes with Greenplum Database operations.
Greenplum Database server supports TLS version 1.2 on RHEL/CentOS systems, and TLS version 1.3 on Ubuntu systems.
Greenplum Database 6 requires the following software packages on RHEL/CentOS 6/7 systems which are installed automatically as dependencies when you install the Greenplum RPM package):
- openssl-libs (RHEL7/Centos7)
- sed (used by
Tanzu Greenplum Database 6 client software requires these operating system packages:
On Ubuntu systems, Greenplum Database 6 requires the following software packages, which are installed automatically as dependencies when you install Greenplum Database with the Debian package installer:
Greenplum Database 6 uses Python 2.7.12, which is included with the product installation (and not installed as a package dependency).
Important: SSL is supported only on the Greenplum Database master host system. It cannot be used on the segment host systems.
Important: For all Greenplum Database host systems, if SELinux is enabled in
Enforcing mode then the Greenplum process and users can operate successfully in the default
Unconfined context. If increased confinement is required, then you must configure SELinux contexts, policies, and domains based on your security requirements, and test your configuration to ensure there is no functionality or performance impact to Greenplum Database. Similarly, you should either disable or configure firewall software as needed to allow communication between Greenplum hosts. See Disable or Configure SELinux.
Greenplum Databased 6 supports these Java versions for PL/Java and PXF:
- Open JDK 8 or Open JDK 11, available from AdoptOpenJDK
- Oracle JDK 8 or Oracle JDK 11
The following table lists minimum recommended specifications for hardware servers intended to support Greenplum Database on Linux systems in a production environment. All host servers in your Greenplum Database system must have the same hardware and software configuration. Greenplum also provides hardware build guides for its certified hardware platforms. It is recommended that you work with a Greenplum Systems Engineer to review your anticipated environment to ensure an appropriate hardware configuration for Greenplum Database.
|Minimum CPU||Any x86_64 compatible CPU|
|Minimum Memory||16 GB RAM per server|
|Disk Space Requirements||
|Network Requirements||10 Gigabit Ethernet within the array
NIC bonding is recommended when multiple interfaces are present
Greenplum Database can use either IPV4 or IPV6 protocols.
You must run Tanzu Greenplum version 6.9 or later on Dell EMC DCA systems, with software version 22.214.171.124 and later.
The only file system supported for running Greenplum Database is the XFS file system. All other file systems are explicitly not supported by VMware.
Greenplum Database is supported on network or shared storage if the shared storage is presented as a block device to the servers running Greenplum Database and the XFS file system is mounted on the block device. Network file systems are not supported. When using network or shared storage, Greenplum Database mirroring must be used in the same way as with local storage, and no modifications may be made to the mirroring scheme or the recovery scheme of the segments.
Other features of the shared storage such as de-duplication and/or replication are not directly supported by Greenplum Database, but may be used with support of the storage vendor as long as they do not interfere with the expected operation of Greenplum Database at the discretion of VMware.
Greenplum Database can be deployed to virtualized systems only if the storage is presented as block devices and the XFS file system is mounted for the storage of the segment directories.
Greenplum Database is supported on Amazon Web Services (AWS) servers using either Amazon instance store (Amazon uses the volume names
ephemeral[0-23]) or Amazon Elastic Block Store (Amazon EBS) storage. If using Amazon EBS storage the storage should be RAID of Amazon EBS volumes and mounted with the XFS file system for it to be a supported configuration.
Tanzu Greenplum 6 supports Data Domain Boost for backup on Red Hat Enterprise Linux. This table lists the versions of Data Domain Boost SDK and DDOS supported by Tanzu Greenplum 6.
|Tanzu Greenplum||Data Domain Boost||DDOS|
|6.x||3.3||6.1 (all versions), 6.0 (all versions)|
Note: In addition to the DDOS versions listed in the previous table, Tanzu Greenplum supports all minor patch releases (fourth digit releases) later than the certified version.

- Data Connectors
- Tanzu Greenplum Text
- Greenplum Command Center

These Greenplum Database extensions are installed with Greenplum Database
- Fuzzy String Match Extension
- PL/Python Extension
- pgcrypto Extension
Greenplum Platform Extension Framework (PXF) - PXF provides access to Hadoop, object store, and SQL external data stores. Refer to Accessing External Data with PXF in the Greenplum Database Administrator Guide for PXF configuration and usage information.
Note: VMware Tanzu Greenplum Database versions starting with 6.19.0 no longer bundle a version of PXF. You can install PXF in your Greenplum cluster by installing the independent distribution of PXF as described in the PXF documentation.
Greenplum Streaming Server v1.5.3 - The Tanzu Greenplum Streaming Server is an ETL tool that provides high speed, parallel data transfer from Informatica, Kafka, Apache NiFi and custom client data sources to a Tanzu Greenplum cluster. Refer to the Tanzu Greenplum Streaming Server Documentation for more information about this feature.
Greenplum Streaming Server Kafka integration - The Kafka integration provides high speed, parallel data transfer from a Kafka cluster to a Greenplum Database cluster for batch and streaming ETL operations. It requires Kafka version 0.11 or newer for exactly-once delivery assurance. Refer to the Tanzu Greenplum Streaming Server Documentation for more information about this feature.
Greenplum Connector for Apache Spark v1.6.2 - The Tanzu Greenplum Connector for Apache Spark supports high speed, parallel data transfer between Greenplum and an Apache Spark cluster using Spark’s Scala API.

R2B X-LOG v5.x and v6.x - Real-time data replication solution that achieves high-speed database replication through the use of Redo Log Capturing method.
Note: Tanzu Greenplum 6 does not support the ODBC driver for Cognos Analytics V11.
Connecting to IBM Cognos software with an ODBC driver is not supported. Greenplum Database supports connecting to IBM Cognos software with the DataDirect JDBC driver for Tanzu Greenplum. This driver is available as a download from VMware Tanzu Network.
Tanzu Greenplum 6.0 through 6.4 are compatible with Tanzu Greenplum Text 3.3.1 through 3.4.1. Tanzu Greenplum 6.5 and later are compatible with Tanzu Greenplum Text 3.4.2 and later. See the Greenplum Text documentation for additional compatibility information.
Tanzu Greenplum 6.15 is compatible only with Tanzu Greenplum Command Center 6.4.0 and later. See the Greenplum Command Center documentation for additional compatibility information.
Greenplum Database provides access to HDFS with the Greenplum Platform Extension Framework (PXF).
PXF can use Cloudera, Hortonworks Data Platform, MapR, and generic Apache Hadoop distributions. PXF bundles all of the JAR files on which it depends, including the following Hadoop libraries:
|PXF Version||Hadoop Version||Hive Server Version||HBase Server Version|
