==Summary==
<dl>
<dt>Privileges
<dd>System manager
<dt>Function
<dd>You can switch streams-parallel, ring, concatenated, GDG-to the next member at any time.
</dl>
==Syntax==
<p class="syntax">SWITCH STREAM streamname [ RESET ]
</p>
<b>Where:</b>
streamname specifies CCAJRNL, CCAJLOG, CHKPOINT, or CHKPNTS. The command is valid for only these streams.
==Usage notes==
If you specify:
<ul>
<li>
<p>Journal stream CCAJRNL or CCAJLOG, the currently active data set is closed and the next data set defined to the stream is opened. </p>
</li>
<li>
<p>Checkpoint stream CHKPOINT or CHKPNTS, the currently active data set in the stream is closed after the next record is written to the data set.</p>
</li>
</ul>
<p>If a SWITCH STREAM CCAJRNL command is issued during CHECKPOINT EXTENDED QUIESCE command processing, the journal will be switched, a new checkpoint issued, and the duration extended quiesce time-out set in CPQZSECS will be reset to its maximum, original value-disregarding the already elapsed time.</p>

<td>This optional parameter will cause any disabled parallel GDG members to be reopened during the switch. </td>
</p><td>Valid only for a CCAJLOG stream specified as a Parallel GDG.</tr></table>
