Hi:
I've a CF structure of 16 Mb. Testing, I've obtained a 2192 (MQRC_STORAGE_MEDIUM_FULL) Reason with 6668 msgs. from 1 to 1164 Bytes of data (without MD & control Headers). The same happened with 5764 msgs. from 1165 to 1420 Bytes, and so on (1421-2048, 5043 msg's...). The manual says that with 200000 msg's of 1Kb it needs about 256 Mb. With 16 Mb the ilustration put about 10000 msg's.
Can someone help me?.
Sorry for my bad english

Have you tried the DISPLAY GROUP command and tried to have a look on it ?

It would give you a display like:
Code:
0769  CSQ5103I xxxxx Structures in group xxxx  951                         
      -----------------------------------------------------------------   
       Name          Size (KB)  %Used  Status      Entries  In use         
       ------------  ---------  -----  ----------  -------  -------       
       CSQSYSTEM01       65536     3   VALID         31903      507       
      -----------------------------------------------------------------   
       End of structures report                                           


What does it give you ?

Just my $0.02

Hi Luis,

You can keep your 0,03 cents;. Jorgen is from Danmark. They don't have any Euros there (yet?).

Cheers, Jan.

By the way, there are a supportpack explaing the topic a bit further:
http://www-3.ibm.com/software/ts/mqseries/txppacs/mp1d.html

You've also got me interested in the calculation of CF capacity, there are a trick about calc. msgs shorther that 1212 (1536-MQMD).

Just my DKK 0.16 similar to $0.02
