<P>
<p>Interface of a DB2 TableSpace. An object of this kind is used to
create a <code>CREATE TABLESPACE ...</code> statement.</p>
<p>A TableSpace can be associated to a <A HREF="../../../../../../org/apache/ws/jaxme/sqls/db2/BufferPool.html" title="interface in org.apache.ws.jaxme.sqls.db2"><CODE>BufferPool</CODE></A>. If it
is, it inherits certain settings from the <A HREF="../../../../../../org/apache/ws/jaxme/sqls/db2/BufferPool.html" title="interface in org.apache.ws.jaxme.sqls.db2"><CODE>BufferPool</CODE></A>,
in particular the <A HREF="../../../../../../org/apache/ws/jaxme/sqls/db2/TableSpace.html#getPageSize()"><CODE>pageSize</CODE></A>.</p>
<p>A tablespace needs to know where data is stored physically. DB2
distinguishes between two possible data locations: System managed
(Files handled by the operating system) and Database managed (Files
handled by the database or Devices). In the latter case the database
will preallocate space for the files or devices, giving a slightly
faster operation. On the other hand, database managed files cannot grow
automatically.</p>
<p>A tablespaces data location is called container. Any tablespace must
have at least one container. Note, that one tablespace cannot have
both system managed containers and database managed containers. If the
first container is system managed, then all containers are, and vice
versa.</p>
