In my environment we are going from raw to mounted filesystems for ORACLE databases as we speak.

We are upgrading to 11.i and new hardware. from K-class & V-class to Superdome and Keystone systems. In addition, we are enabling largefiles that allow for larger than 2GB files. This will decrease the amount of table spaces needed for the large Databases that we will be creating, upto 10GB, and allow for more efficient storage of databases. Also, we are going to the new 170+GB disks for our EMC SAN which are more reliable than the current 80+ GB disks.

So the decrease in performance will be offset somewhat by the OS and hardware upgrades.

And the big PRO is that we can manage the filesystems with our backup utility, NetBackup, more effciently and with greater accuracy, instead of relying on my DBAs to remember to backup their databases.

ctl_cyrusdb

CTL_CYRUSDB(8)						      System Manager's Manual						    CTL_CYRUSDB(8)

NAME

       ctl_cyrusdb - perform operations common to all Cyrus databases

SYNOPSIS

       ctl_cyrusdb [ -C config-file ] -r [ -x ]
       ctl_cyrusdb [ -C config-file ] -c

DESCRIPTION

       Ctl_cyrusdb is used to perform various administrative operations on the Cyrus databases.

       Ctl_cyrusdb  reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.  The configdirectory option is
       used to determine the default location of the Cyrus databases.

OPTIONS

       -C config-file
	      Read configuration options from config-file.

       -r     Recover the databases after an application or system failure.  Also performs database cleanup  like  removing  mailbox  reservations
	      (and any associated mailbox files).

	      All  mailbox  files  are	also checked to make sure the file format matches the configured database type in imapd.conf.  If not, the
	      file is automatically converted using the same logic as cvt_cyrusdb.

       -x     Used with -r to recover the database only.  (Prevents database cleanup).

       -c     Checkpoint and archive the databases.  Changes to the database which are part of committed transactions are written to disk.   Also,
	      a hot backup of the databases is made and inactive log files are removed.

FILES

       /etc/imapd.conf
