Windows: Running multiple server instances on a single system

You can create more than one server instance on your system. Each server instance has its own instance directory, and database and log directories.

Multiply the memory and other system requirements for one server by the number of instances planned for the system.

Windows operating systems The set of files for one instance of the server is stored separately from the files used by another server instance on the same system. Use the steps in Windows: Creating the server instance for each new instance, optionally creating the new instance user.

To manage the system memory that is used by each server, use the DBMEMPERCENT server option to limit the percentage of system memory. If all servers are equally important, use the same value for each server. If one server is a production server and other servers are test servers, set the value for the production server to a higher value than the test servers.

You can upgrade directly from either V6.3 to V7.1. See the upgrade section (Upgrading to V8.1) for more details. When you upgrade and have multiple servers on your system, you must run the installation wizard only once. The installation wizard collects the database and variables information for all of your original server instances.

If you upgrade from IBM Spectrum Protect V6.3 to V8.1 and have multiple servers on your system, all instances that exist in DB2® V9.7 are dropped and recreated in DB2 V11.1. The wizard issues the db2 upgrade db dbname command for each database. The database environment variables for each instance on your system are also reconfigured during the upgrade process.

Windows operating systems A typical IBM Spectrum Protect installation involves one server instance on the IBM Spectrum Protect server computer. You might want to install a second instance if you are configuring in a clustered environment. You might also want to run more than one server on a large computer if you have multiple tape libraries or a disk-only configuration. After you install and configure the first IBM Spectrum Protect server, use the Server Initialization wizard to create additional IBM Spectrum Protect server instances on the same computer.

Windows operating systems By using the Server Initialization wizard, you can install up to four IBM Spectrum Protect server instances on a single system or cluster.
