^%GSIZE Output showing only last page

How best can I capture %GSIZE all pages? Or parameters to use?

The output file is only showing the last page.


I used these options

Device: /usr/cache/mgr/gsizedoc.txt

Parameters? "WNS" =>

Not a direct answer to your question, but did you consider using the Size query of the %SYS.GlobalQuery class, as shown by this DC comment from @David Loveluck on another DC post?


This approach has an advantage over usign %GSIZE as the query in %SYS.GlobalQuery class has a parameter that can make quick estimations of the global sizes (simply counting # of blocks occupied by globals) rather than potentialy very slow exact global size determination always used by %GSIZE 

On Win you could just swith on terminal logging.

For Linux, you could connect to your server using PuTTY or similar and enable logging.

Or make your personal copy %GSIZE => %zGSIZE and disable the artificial page breaks.
(an interesting programming exercise)

If you prefer to code global size calculation by yourself rather than amend ^%GSIZE, the feasible option is to call

set bSize=$$AllocatedSize^%GSIZE(global)

which returns size in bytes for a global mapped to the current namespace. It recognizes the database the global is mapped from, so you don't need to do it yourself. The only thing you need is a global list for the namespace, which can be fetched in several ways, e.g. using $Order(^$G(global)). It can be used on per database basis as well. Pros of this approach:
- speed, as it neither runs query nor instantiates %SYS.GlobalQuery objects;
- AFAIR, there was an error in global size calculation with %SYS.GlobalQuery::Size() query in old Caché versions, up to 2015.1;
- starting from 2015.1, it can be used with subglobals.

- this $$-function is not documented;
- not sure if it existed in 2010.1.
