Preface

This manual explains the causes of warning and error conditions which may occur during the use of the following components of ALLBASE/SQL: SQL, ISQL, SQLUtil, the preprocessors, SQLMigrate, NET, or NETUtil as implemented on HP 3000 computers running under the MPE/iX operating system. It also presents actions to be taken in response to these warning and error conditions. ALLBASE/SQL is the basic component of Hewlett-Packard's relational database management system.

MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP 3000 line of computers. In HP documentation and in talking with HP 3000 users, you will encounter references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without change under MPE/iX. You can continue to use MPE XL system documentation, although it may not refer to features added to the operating system to support POSIX (for example, hierarchical directories).

This manual is for database administrators, application programmers, and others who are using ALLBASE/SQL. It presumes that the user already has a basic understanding of database and ALLBASE/SQL concepts. The contents of this manual are as follows:
