Well, I understand about ZFS and in many cases, I have heard, right or wrong, and from my experience, that ZFS is "not ready for prime time" in every area.

I had a major project on a smalltalk app/db server where ZFS was used and a lot of tuning had to be done. The former "Storage Guy" had set up that machine using ZFS defaults and the memory allocation was screwy as well as performance that was 50% or less than that of UFS on both Solaris 9 and Solaris 10 machines with UFS.

I had to do a few weeks of research and modify the ARC buffer sizes as well as set the read block size to 8K instead of the default 128K (this works for Oracle and other 8K read dbs as well)

However, on many sites, I have seen Solaris 7, 8 and 9 as well as 10. While I will be working primarily on Solaris 10 x64 in a VMware virtual machine, I would appreciate the opportunity to learn VxFS and VxVM as well as VCS if possible, at some point.

If you have any sites besides the manufacturers, I would appreciate. Even if you have links to the ones for Veritas/Symantec, as I was unable to find anything more than a few PDFs that describe overviews instead of instruction.


Thanks in advance,
Mark

NAME
DBIx::Class::Storage::DBI::Informix - Base Storage Class for Informix Support DESCRIPTION
This class implements storage-specific support for the Informix RDBMS METHODS
connect_call_datetime_setup Used as: on_connect_call => 'datetime_setup' In connect_info to set the "DATE" and "DATETIME" formats. Sets the following environment variables: GL_DATE="%m/%d/%Y" GL_DATETIME="%Y-%m-%d %H:%M:%S%F5" The "DBDATE" and "DBCENTURY" environment variables are cleared. NOTE: setting the "GL_DATE" environment variable seems to have no effect after the process has started, so the default format is used. The "GL_DATETIME" setting does take effect however. The "DATETIME" data type supports up to 5 digits after the decimal point for second precision, depending on how you have declared your column. The full possible precision is used. The column declaration for a "DATETIME" with maximum precision is: column_name DATETIME YEAR TO FRACTION(5) The "DATE" data type stores the date portion only, and it MUST be declared with: data_type => 'date' in your Result class. You will need the DateTime::Format::Strptime module for inflation to work. AUTHOR
