SNAPUTIL administrative view and SNAP_GET_UTIL table function - Retrieve utility_info logical data group snapshot information

The SNAPUTIL administrative view and the SNAP_GET_UTIL table function return snapshot information about the utilities from the utility_info logical data group.

Depending on if you are using the administrative view or the table function, refer to one of the following sections:

SNAPUTIL administrative view
SNAP_GET_UTIL table function

SNAPUTIL administrative view

Used in conjunction with the SNAPUTIL_PROGRESS administrative view, the SNAPUTIL administrative view provides the same information as the LIST UTILITIES SHOW DETAIL CLP command.

The schema is SYSIBMADM.

Refer to Table 1 for a complete list of information that can be returned.

Authorization

One of the following authorizations is required to use the view:

SELECT privilege on the SNAPUTIL administrative view
CONTROL privilege on the SNAPUTIL administrative view
DATAACCESS authority
DBADM authority
SQLADM authority

One of the following is required to use the table function:

EXECUTE privilege on the SNAP_GET_UTIL table function
DATAACCESS authority
DBADM authority
SQLADM authority

In addition, to access snapshot monitor data, one of the following authorities is also required:

SYSMON
SYSCTRL
SYSMAINT
SYSADM

Default PUBLIC privilege

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

Example

Retrieve a list of utilities and their states on all database members for all active databases in the instance that contains the connected database.

SELECT UTILITY_TYPE, UTILITY_PRIORITY, SUBSTR(UTILITY_DESCRIPTION, 1, 72)
   AS UTILITY_DESCRIPTION, SUBSTR(UTILITY_DBNAME, 1, 17) AS 
   UTILITY_DBNAME, UTILITY_STATE, UTILITY_INVOKER_TYPE, DBPARTITIONNUM 
   FROM SYSIBMADM.SNAPUTIL ORDER BY DBPARTITIONNUM

The following is an example of output from this query.

UTILITY_TYPE     UTILITY_PRIORITY ...
------------...- ---------------- ...
LOAD                            - ...

3 record(s) selected.

SNAP_GET_UTIL table function

The SNAP_GET_UTIL table function returns the same information as the SNAPUTIL administrative view, but allows you to retrieve the information for a specific database member, aggregate of all database members or all database members.

Used in conjunction with the SNAP_GET_UTIL_PROGRESS table function, the SNAP_GET_UTIL table function provides the same information as the LIST UTILITIES SHOW DETAIL CLP command.

Refer to Table 1 for a complete list of information that can be returned.

Syntax


>>-SNAP_GET_UTIL--(--+--------+--)-----------------------------><
                     '-member-'

The schema is SYSPROC.

Table function parameter

member: An optional 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. If this input option is not used, data will be returned from all active database members. An active database member is a member where the database is available for connection and use by applications.

If member is set to NULL, an attempt is made to read data from the file created by SNAP_WRITE_FILE procedure. Note that this file could have been created at any time, which means that the data might not be current. If a file with the corresponding snapshot API request type does not exist, then the SNAP_GET_UTIL table function takes a snapshot for the currently connected database and database member number.

Authorization

One of the following authorizations is required:

EXECUTE privilege on the SNAP_GET_UTIL table function
DATAACCESS authority

In addition, to access snapshot monitor data, one of the following authorities is also required:

SYSMON
SYSCTRL
SYSMAINT
SYSADM

Default PUBLIC privilege

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

Examples

Example 1: Retrieve a list of utility ids with their type and state for the currently connected database member on database SAMPLE.

SELECT UTILITY_ID, UTILITY_TYPE, UTILITY_STATE 
   FROM TABLE(SNAP_GET_UTIL(-1)) AS T WHERE UTILITY_DBNAME='SAMPLE'

The following is an example of output from this query:

UTILITY_ID           UTILITY_TYPE               STATE
-------------------- -------------------------- --------
                   1 BACKUP                     EXECUTE

  1 record(s) selected.

Example 2: Retrieve a list of utility ids with their type, member number and database partition number for the currently connected database member.

SELECT UTILITY_ID, UTILITY_TYPE, MEMBER, DBPARTITIONNUM
  FROM TABLE(SNAP_GET_UTIL(-1)) AS T

The following is an example of output from this query:

UTILITY_ID  UTILITY_TYPE               MEMBER DBPARTITIONNUM
----------- -------------------------- ------ --------------
          2 BACKUP                          2              2
