sa_validate system procedure

Validates all, or parts, of a database.

Syntax 
sa_validate(
  [ [ owner_name.]tbl_name  | owner_name ]
)
Arguments

  • tbl_name   Use this optional VARCHAR(128) parameter to specify the name of a table or materialized view to validate.

  • owner_name   Use this optional VARCHAR(128) parameter to specify an owner. When specified by itself, all tables and materialized views owned by the owner are validated.

Permissions

DBA authority required

Side effects

None

Remarks

If you specify sa_validate() (no arguments), the database server validates all tables, materialized views, indexes, checksums, and the database file.

If neither owner nor tbl_name are specified, all tables and materialized views in the database are validated. Also, the database itself is validated, including checksum validation, and validation that the number of rows in the each table or materialized view matches the number of rows in each associated index.

The values for tbl_name and owner_name are strings and must be enclosed in quotes.

The procedure returns a single column named Messages. Errors returned during validation appear in the column. If validation succeeds without error, the column contains No error detected.

Caution

Validating a table or an entire database should be performed while no connections are making changes to the database; otherwise, errors may be reported indicating some form of database corruption even though no corruption actually exists.

Example

The following statement performs a validation of tables and materialized views owned by DBA:

CALL sa_validate( owner_name = 'DBA' );
