DB2 10.5 for Linux, UNIX, and Windows

HEALTH_DB_INFO table function

The HEALTH_DB_INFO table function returns information from a health snapshot of a database.

Important: This table function has been deprecated and might be removed in a future release because the health monitor has been deprecated in Version 9.7. It is not supported in DB2® pureScale® environments. For more information, see Health monitor has been deprecated..

Syntax


>>-HEALTH_DB_INFO--(--dbname--,--member--)---------------------><

The schema is SYSPROC.

Table function parameters

dbname: An input argument of type VARCHAR(255) that specifies a valid database name in the same instance as the currently connected database when calling this function. Specify a database name that has a directory entry type of either "Indirect" or "Home", as returned by the LIST DATABASE DIRECTORY command. Specify the null value to take the snapshot from all databases under the database instance.
member: An input argument of type INTEGER that specifies a valid database member number. Specify -1 for the current database member, or -2 for an aggregate of all active database members. An active database member is a member where the database is available for connection and use by applications.
If the null value is specified, -1 is set implicitly.

Authorization

One of the following authorities is required to execute the routine:

EXECUTE privilege on the routine
DATAACCESS authority
DBADM authority
SQLADM authority

Default PUBLIC privilege

In a non-restrictive database, EXECUTE privilege is granted to PUBLIC when the function is automatically created.

Example

SELECT * FROM TABLE(HEALTH_DB_INFO('',-1)) AS T
