Dear Chris,

We just migrate an Application from RM Cobol to Visual Cobol for Eclipse and we noted that our Files are very diferent in Size. Could you please give a reason for that ??.

TAMAÑO EN RMCOBOL = 514490368

 

TAMAÑO EN VISUAL COBOL = 1241272408      ( como tuvimos problema con comp-6 , lo eliminamos y dejamos con comp-3, tiene las mismas clave principal y segundarias)

Dear Sirs,

Any answer about this question...????

You state that you are using Eclipse.  However, Eclipse is a development environment for both Linux/Unix and Windows.  Which operating system are you using?  

Also, an output from RMMAPINX (see RM Users Guide for use) would be helpful in understanding the file's characteristics.  Simply looking at size does not tell us much.  But RMMAPINX will tell how much space is used for storing the index trees versus the data records, and the amount of compression that is achieved.

Dear Sir,

We usThere are several differences:




1. The size of the log with the previous definition (RM and COMP-6) occupies 133 bytes, while the current (VC and COMP-3) occupies 183 bytes.




2. The size of the indices; before the primary key occupies 23 bytes and with duplicate keys occupy 4, 2, 13 and 1 bytes; now the primary key occupies 30 bytes and with duplicate keys occupy 5, 3, 16 and 1 bytes.




3. RM indexed files have the indication in the configuration file that uses both data compression and indices


                RUN-FILES INDEX-data-compression = yes force-force-closed = no data = no force-disk = no

                RUN-FILES INDEX-force-index = no key-compression = yes

     While now no compression is required.




Does it justify why the deal triple space ?, I can not tell; but obviously now the same data take up more space.e Linux for Fevelopment and Unix AIX for Deployment.

Sorry Sir,

Hi Pedro,

If you are now using COMP-3 instead of COMP-6 then your fields will be larger. COMP-6 in RM is unsigned PACKED-DECIMAL and COMP-3 in VC is signed PACKED-DECIMAL so an extra byte of storage may be required to hold the sign.

You can emulate the RM COMP-6 behavior by using the RM dialect directive which will set the COMP-6"2" directive on. Then if you define your data as COMP-6 and it has no sign in the PIC then the extra byte will not be used.

You can also specify data and key compression on your files using the DATACOMPRESS or KEYCOMPRESS directives or by setting this on in a file handler configuration file.

Thanks
