Operating Systems AIX Slow NFS when cio/dio enabled Post 302589294 by zxmaus on Wednesday 11th of January 2012 08:29:43 AM

I do not know your DB at all but you should use cio in any case only for the real database files (.dbf on oracle) and not for binaries, dumps and similar filesystems - and I would not think you are really sharing the Database files themselves via nfs ?

file writing over nfs very slow

Hi guys, I am trying something. I wrote a simple shell program to test something where continuous while loop writes on a file over the nfs. The time taken to write "hello" 3000 times take about 10 sec which is not right. Ideally it should take fraction of seconds. If I write on the local disk, it... (1 Reply)

smd-server(1)						 Sync Mail Dir (smd) documentation					     smd-server(1)

NAME
smd-server - sends diffs and mails to smd-client SYNOPSIS
smd-server [--exclude glob] [-v|--verbose] [-d|--dry-run] [--get-mddiff-cmdline] [--stop-after-diff] [--override-db dbf] [--dump-stdin tgt] endpoint mailboxes DESCRIPTION
smd-server needs to know a name (endpoint) for the client (that must not be used by others) and a list of mailboxes (directories). smd-server first calls mddiff(1), then prints on stdout the generated diff. It then accepts from stdin a small set of commands a client may issue to request a file (or parts of it, like the header). smd-server is in charge of committing the db file used by mddiff(1) in case the client communicates a successful sync. OPTIONS
-v --verbose Increase program verbosity (printed on stderr) -d --dry-run Do not perform any action for real -n --no-delete Do not track deleted files --exclude glob Exclude paths matching glob --override-db dbf Use dbf as the db-file --get-mddiff-cmdline Print the command line used for mddiff and then exist --stop-after-diff Send the actions to the other endpoint and exit. If used in conjunction with --override-db, dbf is removed just before exiting --dump-stdin tgt Dump standard input to tgt and exit NOTES
smd-server is a low level utility. You should use higher level tools like smd-pull(1) and smd-push(1) SEE ALSO
mddiff(1), smd-client(1), smd-pull(1), smd-push(1) AUTHOR
