Installing <strong>Caché</strong> on OpenVMS<br />

- From the [Home] > [Configuration] > [Network Settings] > [Legacy Network Connections] page,<br />

delete any DCP connections from the network table that you do not need; they were only<br />

there to support clusters.<br />

The upgrade does not automatically make these changes because it cannot detect which DCP<br />

connections support clusters and which might be for communicating with machines that are still<br />

running a prior release of <strong>Caché</strong>. With ECP, networking the cluster automatically configures the<br />

network tables as needed; it is not necessary to define any ECP connections between the cluster<br />

members to support <strong>Caché</strong> clusters. However, you cannot access the ECP connection created<br />

automatically. If the configuration requires ECP, to gain read-only access to privately mounted<br />

databases on another cluster member, you must define those connections.<br />

3.4 Special Considerations<br />

The following sections describe particular issues or tasks associated with licensing, specific platforms,<br />

or kinds of installations:<br />

• Multiple <strong>Caché</strong> Instances<br />

• Patch for Client Access Using Kerberos on Itanium Platform<br />

• SYSTEM-F-SECTBLFUL Error<br />

• INSTALL-E-NOSHRADR Error<br />

• Uninstall <strong>Caché</strong><br />

3.4.1 Multiple <strong>Caché</strong> Instances<br />

You can install and simultaneously run multiple instances of <strong>Caché</strong> 4.0 and later on a single OpenVMS<br />

machine. Install <strong>Caché</strong> as for a single installation, giving each instance a unique name, a unique<br />

installation directory, and unique port numbers.<br />

Please reference the Multiple <strong>Caché</strong> Instances section of the <strong>Caché</strong> System Administration <strong>Guide</strong> for<br />

further details.<br />

3.4.2 Patch for Client Access Using Kerberos on Itanium Platform<br />

Applications attempting to access OpenVMS servers that use Kerberos authentication must install the<br />

patch, HP-I64VMS-TCPIP-V0505-11ECO1-1. The Engineering Change Order (ECO) is for TCP/IP,<br />

not the actual operating system. Without this patch, the server often transmits erroneous response<br />

packets back to clients using the C++ binding, ODBC, JDBC, or Studio.<br />
