</table><br />
<p>See [[DSPOPT parameter|DSPOPT: Dataspace and hiperspace options]] for an explanation of the terms DATASPACE TYPE, SLOWRD, and SLOWWR.</p><br />
==Usage==<br />
<p>Among things monitored are page usage high-water marks, number of calls to the dataspace data movement routines, the quantity of data moved to and from the dataspaces, and page-fault statistics for dataspace data movement.</p><br />
<p>Since IBM support for access to real storage above two gigabytes is limited to 2-gigabyte chunks of storage, multiple 2-gigabyte dataspaces are chained together and logically mapped as either CCATEMP or CCASERVR. </p><br />
<p>Under the 4K PAGES heading, each X'00080000' number of 4K blocks is a 2-gigabyte chunk. There are two logical dataspaces, CCATEMP and CCASERVR. However, since IBM requires that every dataspace be named, the additional (if required) physical, 2-gigabyte chunks have generated sequential names beginning with CCA00001.</p><br />
====Considering the SLOWRD and SLOWWR statistics====<br />
<p>The SLOWRD and SLOWWR statistic occur when <var class="product">Model&nbsp;204</var> uses the Assembly Language Move Character Long (MVCL) facility, instead of the Assembly Language Move Page (MVPG) facility to move a 4-K page to or from a CCASERVR or CCAAPSY dataspace. This happens when the page that you referenced in the dataspace is not in memory. A page fault occurs and MVPG fails with a nonzero return code. When that happens, <var class="product">Model&nbsp;204</var> switches to MVCL and moves the page. MVCL waits for the page fault to resolve, whereas MVPG does not. When this switching takes place you will see SLOWRD and SLOWWR statistics increase, although usually they are not significant.</p><br />
<p>In the MONITOR DATASPACE output check whether less than 20 percent of PAGES WRITN were SLOWWRs. If the percentage gets higher, it indicates that memory for dataspaces or hiperspaces is constrained and that the pages referenced when you do a server swap or an APSY load are not in memory.</p><br />
<p>The percentage of SLOWRDs and SLOWWRs generally does not represent a problem unless the percentages compared to PAGES READ or PAGES WRITN exceed 20-30 percent. Then, the only action you can take to reduce the percentages is by adding more central or expanded storage or by reducing the size of the CCASERVR or CCAAPSY dataspaces. </p><br />
==Example 2==<br />
====Output from the operating system====<br />
<p>There are five physical dataspaces in the following example. When a TSO user issues the following command, where DVUSER2 is the job name of the Online using the dataspaces, the following output is displayed:</p><br />
<p class="code"><b>/D J,DVUSER2</b><br />
