Upgrading the Server

To upgrade from Adaptive Server 15.5 Noncluster Edition to the 15.5 Cluster Edition, use the upgrade procedures described in this manual. Look here to learn about upgrade compatibilities.

You can upgrade to the Cluster Edition from:

12.5 through 12.5.4 ESD #8
15.0 through 15.5

You can upgrade to this version of the Cluster Edition from:

15.0.1 Cluster Edition to 15.0.1 Cluster Edition ESD #4
15.0.3 Cluster edition
12.5.4 including ESDs and 15.0.x versions including 15.5 nonclustered server
Note: Once you have upgraded to the 15.5 Cluster Edition you cannot downgrade back to an nonclustered 15.x or earlier server. You can downgrade back to 15.0.1 Cluster Edition through 15.0.1 Cluster Edition ESD #4, Cluster Edition 15.0.3 and Cluster Edition 15.5.

Only upgrades to and from the same page size are supported. Use sybmigrate to re-create the schema and load data from one page size to another.

Use Adaptive Server plug-in or the sybcluster utility to perform many of the pre-upgrade and upgrade steps for you. You can also upgrade the server manually.

To use Adaptive Server plug-in – See the Upgrading the Server With ASE Plug-in topic.
To use sybcluster to upgrade the server – See the Upgrading the Server with sybcluster topic .
To upgrade the server manually – follow the instructions in this and succeeding sections.

See the Migrating topic for information about migration.

Note: To upgrade from a shared installation mode to a private installation mode in Adaptive Server 15.5 Cluster Edition refer to the Release Bulletin for special upgrade instructions.

Preupgrade Tasks
You must have SA privileges to perform an upgrade.
Manually Upgrade Overview
Manually upgrading Adaptive Server consists of six processes.
Preparing the Database and Devices for the Upgrade
If you ran the preupgrade, it scanned the system catalogs and calculates how much additional space you need to perform the upgrade.
Upgrading the Server Using ASE Plug-in
To login to the ASE plug-in see instructions starting with the Setting the Environment and Starting Unified Agents topic.
Upgrading the Server Using sybcluster
Learn about the upgrade process using the sybcluster utility, and preupgrade tasks to complete before upgrading your old server. You can also perform a manual upgrade to the Cluster Edition. See the Manually Upgrading topic for how to do this.
Postupgrade Tasks
Complete these steps after upgrading to the Cluster Edition.
Recovering from a Failed Upgrade
During the upgrade process, the transaction log may get full due to the catalog changes that are made. If so, log in to the new server using isql, and issue:
Upgrading Java in the Database
The Pluggable Component Interface (PCI) configuration values are used by all of the nodes in a cluster. To share files between nodes, using working directories, you need shared directory locations in the file system that are visible to all nodes using the same path.
Migrating
For complete instructions about using dump and load to migrate to the Cluster Edition, see the Adaptive Server 15.5 installation guide for your platform.
