CHAPTER 3 Working with Database Objects

113

Choosing a block size for your database

Example

The following statement creates a large database on a UNIX raw partition with
a Catalog

PAGE SIZE

of 4KB, and an

IQ PAGE SIZE

of 128KB. By default, the

IQ Store size is 8MB and the Temporary Store is 4MB.

CREATE DATABASE ’company’ IQ PATH ’/dev/rdsk/c2t6d0s3’

PAGE SIZE 4096

IQ PAGE SIZE 131072

Enabling Java in the database

By default, Java support is ON for IQ databases. It can be turned off with the

JAVA OFF

option. With Java ON:

You can write a Java procedure that accesses tables in the Catalog Store or
the IQ Store. These queries are processed like any other query.

You cannot use a Java-based user-defined function within a query to an IQ
table, but you can use it on Catalog Store tables.

Windows NT users can also use Java-based user-defined functions in
queries on tables in an Adaptive Server Anywhere database, or queries to
IQ tables from an Adaptive Server Anywhere database, using the remote
access capabilities described in the Adaptive Server IQ Installation and
Configuration Guide
.

You cannot store Java data in an IQ table. If you attempt to create an IQ
column of type Java, you receive an error, and you may cause the database
server to fail.

Additional support for Java will be provided in a subsequent release. For
information on Java support in Adaptive Server Anywhere, see Part 3, “Java in
the Database” in the Adaptive Server Anywhere User’s Guide. The chapter
entitled “Data Access Using JDBC” is particularly relevant for IQ users.
