==Syntax==
MONITOR SIZE {[JOURNAL | JRNL] | [CHECKPOINT | CHKP] | CCAJRNL | CCAJLOG | CHKPOINT | CHKPNTS}


Where:
<table>
<tr>
<th><var>JOURNAL</var></th>
<td> (or <var>JRNL</var>) specifies to display the definitions and current usage for the CCAJRNL and CCAJLOG streams.</td>
</tr>

<tr>
<th><var>CHECKPOINT</var></th>
<td> (or <var>CHKP</var>) specifies to display the definitions and current usage for the CHKPOINT and CHKPNTS streams.</td>
</tr>

</table>
==Example==
MONITOR SIZE CHKP
DDNAME TYPE TRKS_ALLOC TRKS_USED PCT_USED
________ _________________ __________ _________ ________
CHKPOINT (GDG STREAM)
CHK1 (DATASET) 100 40 40%
CCA008\M204V710.CHKPOINT.G3371V00\+5
CHKPNTS (DATASET) 5000 3000 60%
CCA013\M204V710.CHKP5

In the previous example, CHKPOINT is defined as a GDG STREAM consisting of member CHK1, a GDG data set. The volser, GDG data set name and relative generation are displayed.
CHKPNTS is defined as a simple data set. Its volser and data set name are also displayed.
Note: CPMAX=1 and a checkpoint occurs, the CHKPOINT data set, in this case CHK1, is repositioned to the beginning of the data set (the first data set if a GDG) and the TRKS_USED is reset to zero.
When a sub transaction checkpoint is taken, a switch from CHKPOINT to CHKPNTS or vice-versa occurs and the target of the switch is repositioned to the beginning of the data set and TRKS_USED is reset to zero but starts increasing immediately. The switched from member has TRKS_USED set to zero. 
In addition, you can restrict the output of the MONITOR SIZE command to only the one specified stream, for example:
MONITOR SIZE CCAJLOG
