9427.0. "Memory Allocation" by VAXRIO::WK_ESPOZEL () Tue Apr 08 1997 12:04

    Hi,
    
    I am migrating an application from AIX to DECUNIX.
    I have some doubts about memory allocation
    
    1) The VSZ column is Virtual Size of the Process....
    
    Does the process bellow  allocates 21.Mega of swap file   ???
    
      PID TTY      S           TIME       SL PAGEIN   VSZ  RSS %CPU %MEM
    COMMAND
    21182 ttyqb    S  +     0:21.19       12      2 21.6M 6.9M  1.0  2.7
    CGOAMGR

    2) Is it possible to know  what % of RSS is shared with another process
    ?   At AIX there are two columns that (I think ) gives this information
    : TRS The size of resident-set (real memory) of text.  and
     TSIZ  The size of text (shared-program) image.
    
    How the VSZ is allocated ????
    
    Thanks in advance, Heraldo
