Sets the file access mode to direct I/O instead of the default buffered I/O. Applies only to new databases or to databases that will be migrated from Analytic Services release 6.2 or earlier.
This setting does not apply to aggregate storage databases.
DIRECTIO TRUE | FALSE
TRUE | Direct I/O is used, when possible, for newly created or migrated databases. |
FALSE | This is the default. Buffered I/O is used for newly created or migrated databases. |
For each database, Analytic Services stores a setting in its security file whether or not to use buffered I/O or direct I/O when it accesses the database. By default, when Analytic Services creates a new database or migrates one from release 6.2 or earlier, it sets this I/O access mode setting in the security file to buffered I/O. You can specify the DIRECTIO TRUE configuration setting to change the default setting for new or migrated databases to be direct I/O.
To alter the I/O access mode setting for a database thereafter, use Administration Services or MaxL. For more information, see the online help or HTML documentation for those components.
DIRECTIO TRUE
When Analytic Services is restarted, the file access mode is set to direct I/O for new databases and databases migrated from release 6.2 or earlier.
