Describes the host servers that are commonly used with iSeries™ Access for Windows®, and describes how to effectively manage and use them.
This topic provides brief descriptions of server functions that run on an iSeries server and technical information specific to host servers that are used by the iSeries Access for Windows product. These are not all of the servers used by iSeries Access for Windows, and this topic does not address all of the servers on the host (iSeries) system.
Host servers handle requests from client PCs or devices such as running an application, querying a database, printing a document, or even performing a backup or recovery procedure. iSeries computers are full-function servers capable of performing many tasks at once, including file, database, applications, mail, print, fax, and wireless communications. When these tasks are handled by several different servers, server management and coordination becomes complex. Having all of your servers on one integrated system greatly reduces the overall cost and complexity of managing your network.
These servers are used by iSeries Access for Windows, but are designed so that other client products can also use them. This topic focuses on how these servers are used by iSeries Access for Windows.
The servers discussed here are all optimized servers, and are included with the base option of i5/OS. To use the iSeries Navigator function of iSeries Access for Windows, install the Host Server option.
If you are not using any iSeries Access for Windows products or iSeries NetServer™ and would like to remove the Host Server option, you should end the subsystems used by these servers before you remove the option. End the QBASE or QCMN subsystem (for host servers with APPC support), the QSYSWRK and QUSRWRK subsystems (for host servers with sockets support), and the QSERVER subsystem (for database and file server). Problems may occur if you try to delete the option while any of these subsystems are active.
