Setting policies to automate storage tiering using SmartTier for Oracle

Use the dbdst_preset_policy command to set a policy based on file name patterns before the files are created.

Table: dbdst_present_policy command options shows the preset policies command options.

Table: dbdst_present_policy command options

Command option

Description

-d directory

Indicates the directory on which the placement policy will be applied.

-e

Enforces the file system of the specified directory. Use this option if there was an error in the previous enforcement that has been corrected and needs to be enforced again.

-R

Removes all pattern-based placement policies related to this directory.

-l

Lists the existing file placement that is set to the specified directory.

-P pattern_spec

Specifies file patterns and class assignment. This option will automatically place files in the desired class as soon as they are created. Existing files and newly created files will be moved immediately to the class specified.

-f pattern file

Specifies a file that contains a particular class and pattern. New files with this pattern will be placed in the class immediately. Existing files will be moved as well.

-E

Specifies that existing files should be moved to the designated class in a one-time move to be scheduled at a later time, such as the sweeptime specified in the dbdst_admin command.

To create a preset policy

  • Use the dbdst_preset_policy command as follows:
    $ dbdst_preset_policy -S $oracle_sid -d directory \
[ -e | -R | -l | -P pattern_spec | -f pattern_file ] [-E]

    where pattern_spec has the format of "class=pattern,pattern,...[:class=pattern,pattern,...]"

    For example:

    $ /opt/VRTS/bin/dbdst_preset_policy -S VRTS11r2  \
     -d /data11r2/VRTS11r2 -P "MEDIUM=*.dbf:FAST=*.log"

Assign placement policy file successful on filesystem /data11r2
Begin enforcing filesystem /data11r2 ...
Enforce placement policy successful on filesystem /data11r2
