Network and connectivity requirements for Db2 environments

Overview

This topic outlines the network and connectivity requirements for the Delphix Engine and Db2 standby and target environments.

Port allocations specific to DB2

The Delphix Engine makes use of the following network ports for Db2 standby and target:

Inbound to the Delphix engine port allocation

Protocol

Port number

Use

TCP/UDP

111

Remote Procedure Call (RPC) port mapper used for NFSv3 mounts

Note: RPC calls in NFSv3 use additional fixed ports for supporting services (lockd, mountd and statd) seen below.

TCP

1110

NFS Server daemon status and NFS server daemon keep-alive (client info)

TCP

2049

NFS Server daemon from vFiles to the Delphix Engine

TCP

54043

NFSv3 mount daemon

TCP

54044

NFSv3 stat daemon (lock state notification service)

TCP

54045

NFSv3 lock daemon/manager

UDP

33434 - 33464

Traceroute from standby and target hosts to the Delphix Engine (optional)

Outbound from a standby or target environment port allocation

Protocol

Port numbers

Use

TCP

873

Rsync connections used during V2P.

TCP

8415

DSP connections used for monitoring and script management. Typically DSP runs on port 8415.

Inbound to a standby or target environment port allocation

Protocol

Port numbers

Use

TCP

22

SSH connections to the target environment

HADR service ports

The HADR ports set for HADR_LOCAL_SVC and HADR_REMOTE_SVC on the Db2 Master and Standby hosts. The specific ports used at the customers' discretion and need to be specified during the linking process. It is highly recommended that these ports also be defined in the /etc/services file to ensure that they are only used by Db2 for the specified databases.

General outbound from the Delphix engine port allocation

Protocol

Port numbers

Use

TCP

25

Connection to a local SMTP server for sending email

TCP/UDP

53

Connections to local DNS servers

UDP

123

Connection to an NTP server

UDP

162

Sending SNMP TRAP messages to an SNMP Manager

TCP

443

HTTPS connections from the Delphix Engine to the Delphix Support upload server

TCP/UDP

636

Secure connections to an LDAP server

TCP

8415

Connections to a Delphix replication target. See Configuring Replication.

TCP

50001

Connections to source and target environments for network performance tests.

General inbound to the Delphix engine port allocation

Protocol

Port number

Use

TCP

22

SSH connections to the Delphix Engine

TCP

80

HTTP connections to the Delphix GUI

UDP

161

Messages from an SNMP Manager to the Delphix Engine

TCP

443

HTTPS connections to the Delphix Management Application

TCP

8415

Delphix Session Protocol connections from all DSP-based network services including Replication, SnapSync for Oracle, V2P, and the Delphix Connector.

TCP

50001

Connections from source and target environments for network performance tests via the Delphix CLI.

Firewalls and intrusion detection systems (IDS)

Production databases on source environments (for dSources) are often separated from the non-production environment by firewalls. Firewalls can add milliseconds to the latency between servers. Accordingly, for best performance, there should be no firewalls between the Delphix Engine and the virtual database (VDB) target environments. If the Delphix Engine is separated from a source environment by a firewall, the firewall must be configured to permit network connections between the Delphix Engine and the source environments for the application protocols (ports) listed above.

Intrusion detection systems (IDSs) should also be made permissive to the Delphix Engine deployment. IDSs should be made aware of the anticipated high volumes of data transfer between dSources and the Delphix Engine.

AppData port requirementsThe use of AppData requires the following ports/protocols.
Two important notes about these specifications:

  1. The next release of the Delphix Engine will significantly augment the port/protocol utilization of AppData. The upcoming-only requirements have been marked with a *.

  2. AppData V2P uses RSYNC to export to the target. RSYNC between the target and Delphix Engine is not required for general virtualization usage. The V2P-only requirements have been marked with a ^.
