What are the steps to accessing a file

2014-10-02 Thread john . x . posada
Hi, guys...I'm having discussion with my service support people over what I
deem to be poor network access speed of FM files.

I'm trying to define what FM does when it accesses a series of files from
the perspective of disk and network read/writes, for something such as
search and replace.

It would be in the form similar to the following, for unstructured:

   Access file on disk
   Download to application.
   Apply file lock and write locked file to disk
   Write duplicate of file on disk as backup
   Perform examination in file and make changes necessary
   Write file to disk
   Delete lock file.

I'm sure I don't have this exactly right...anyone know better?

If you're talking about doing a find and replace across a .book with
none of the .fm files open, my impression is that it iterates through
the files as follows:

- create .lck file
- read file into memory
- make changes
- write to disk
- delete .lck file

I think that's one of those FM features that is so old that it should
be avoided.
