Top Forums UNIX for Advanced & Expert Users how to figure out the size in MB for an informix database Post 6572 by mbb on Friday 7th of September 2001 08:00:01 AM

Optimus,

Your method is mostly correct, but I am not sure about your math!

acutal_size = free * 4096 = bytes

/ 1024 = Kbytes
/ 1024 = Mbytes
/ 1024 = GBytes.

Thats makes the total size of a chunk at 0.9gb

Free:

692mb
944mb
621mb
194mb

Do these numbers seem familiar? Plug them into a spread sheet for more accurate results.

Plus, be very careful when changing the disk allocations of logical volumes underneath Informix' nose. If you screw up, Informix won't like it and a level 0 archive/restore might not cut it either. Do a dbexport to disk or tape. It may take a while, and the restoration, with dbimport, may be a bit trickier with large tables. The benefit would be that the format (dbschema + unload files) is simple and does not rely on the underlying instance configuration on being exactly the same.

MBB.

vdltodmx(1)						      General Commands Manual						       vdltodmx(1)

NAME
vdltodmx - dmx configuration file parser and printer SYNOPSIS
vdltodmx infile outfile DESCRIPTION
vdltodmx reads the input file, which should be in VDL configuration file format. After a successful parse, a file in Xdmx configuration file format is written to the output file. The VDL file format is used with xmovie, which is available from http://www.llnl.gov/icc/lc/img/xmovie/xmovie.html EXAMPLE
Given the following VDL-format file: 0 2 # # 2560 2048 Left two-thirds [restrict=*:2] 2 :2.1 1280 2048 0 0 0 0 :2.2 1280 2048 1280 0 0 0 4 1280 1024 0 0 1280 1024 0 1024 1280 1024 1280 0 1280 1024 1280 1024 # 2560 2048 Right two-thirds [restrict=*:2] 2 :2.2 1280 2048 0 0 0 0 :2.3 1280 2048 1280 0 0 0 4 1280 1024 1280 0 1280 1024 1280 1024 1280 1024 2560 0 1280 1024 2560 1024 the following DMX-format file will be produced: # # virtual "Left two-thirds" 2560x2048 { display :2.1 1280x2048; display :2.2 1280x2048 @1280x0; } # virtual "Right two-thirds" 2560x2048 { display :2.2 1280x2048; display :2.3 1280x2048 @1280x0; } BUGS
If the VDL file is not in the expected format, the program will probably dump core. SEE ALSO
