Caché Installation Guide - InterSystems Documentation

1. Check if times in Caché and OpenVMS are synchronized, using the following commands at the
Caché prompt:
> Write $ZTIME($P($H,",",2))
> !SHOW TIME
The first displays the Caché time and the second displays the OpenVMS system time. The two
values should be approximately the same.
2. Run the UTC$TIME_SETUP procedure to set the system time.
3. If this procedure exits prematurely, enter the following command at the OpenVMS prompt:
$ @SYS$MANAGER:UTC$TIME_SETUP.COM "" BOTH
Post-installation Tasks
This command forces an update of both the time zone and Time Differential Factor (TDF) data.
Make sure these values are consistent. For example, if the selected main time zone is US (33),
Eastern zone (6) or EST, the appropriate TDF is -5:00 (or -4:00, if Daylight Saving Time is in
effect).
You can configure OpenVMS to automatically adjust for Daylight Saving Time as described in
the OpenVMS documentation.
3.3.4 Perform Post-installation Upgrade Tasks
If you are upgrading, there are additional upgrade tasks to perform after the installation is complete:
• Recompile Objects — you must recompile all Caché Objects applications in all namespaces by
running the following command:
Do $system.OBJ.CompileAllNamespaces("u")
Note:
This method both upgrades and compiles the class dictionaries in every namespace.
• Regenerate Proxy Classes — you must regenerate any proxy classes you had generated in the
upgraded instance by following the instructions in the appropriate guides in the Caché Language
Bindings set.
• 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 the latest version of Caché 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.
