3.1.1.3 Show Free Space Using %FREECNT
Caché also provides an additional tool to monitor the storage growth of your databases. This utility is
called %FREECNT. Its output shows the free space available in a database. From a namespace other
than %SYS, the utility shows the free space of the databases in that namespace:
USER>Do ^%FREECNT
Databases Selected
------------------
c:\MyCache\mgr\user\
Device:
Right margin: 80 =>
Cache Database Free Space
Feb 15 2008 7:28 PM
Database Max Size Size Available %Free Disk Free
c:\MyCache\mgr\user\ Unlimited 1MB 0.52MB 52 42.72GB
From the %SYS namespace, you may choose to display the free space of all databases by entering an
asterisk (*) at the prompt, or enter one database directory name:
%SYS>Do ^%FREECNT
Database directory to show free space for (*=All) *
Databases Selected
