Installing Caché on OpenVMS
This upgrades and compiles the class dictionaries in every namespace.
• Update Cluster Configurations (OpenVMS clusters only) — prior to Caché 5.0 when
configuring a Caché cluster it was necessary to define the network type for the cluster
(UDP or Ethernet) and define DCP connections between the cluster members. This is no
longer necessary. ECP is the default for new installations.
After the upgrade to 5.2 from 4.1, a Caché cluster configuration needs to be changed
manually. The changes are in two places of the System Management Portal:
- Enable the ECP service from the [Home] > [Security Management] > [Services] page.
Click %Service_ECP, select the Service enabled check box, and click Save.
- From the [Home] > [Configuration] > [Legacy Network Connections] page, delete any
DCP connections from the network table that you do not need; they were only there
to support clusters.
The upgrade does not automatically make these changes because it cannot detect which
DCP connections support clusters and which might be for communicating with machines
that are still running a prior release of Caché. With ECP, networking the cluster automatically
configures the network tables as needed; it is not necessary to define any ECP
connections between the cluster members to support Caché clusters. However, you cannot
access the ECP connection created automatically. If the configuration requires ECP, to
gain read-only access to privately mounted databases on another cluster member, you
must define those connections.
3.4 Special Considerations
The following sections describe particular issues or tasks associated with licensing, specific
platforms, or kinds of installations:
• Multiple Caché Instances
• Patch for Client Access Using Kerberos on Itanium Platform
• SYSTEM-F-SECTBLFUL Error
