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.

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:
  • SELECT privilege on the SNAPUTIL administrative view
  • CONTROL privilege on the SNAPUTIL administrative view
  • DATAACCESS authority
In addition, one of the following privileges or authorities is also 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

Example

Retrieve a list of utilities and their states on all database partitions 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 example is a sample output from this query.
UTILITY_TYPE     UTILITY_PRIORITY ...
------------...- ---------------- ...
LOAD                            - ...

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 partition, aggregate of all database partitions or all database partitions.

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.

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

The schema is SYSPROC.

Table function parameter

dbpartitionnum
An optional input argument of type INTEGER that specifies a valid database partition number. Specify -1 for the current database partition, or -2 for an aggregate of all active database partitions. If this input option is not used, data will be returned from all active database partitions. An active database partition is a partition where the database is available for connection and use by applications.

If dbpartitionnum 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 partition 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

Example

Retrieve a list of utility ids with their type and state for the currently connected database partition on database SAMPLE.
SELECT UTILITY_ID, UTILITY_TYPE, UTILITY_STATE 
   FROM TABLE(SNAP_GET_UTIL(-1)) AS T WHERE UTILITY_DBNAME='SAMPLE'
The following example is a sample output from this query.
UTILITY_ID           UTILITY_TYPE               STATE
-------------------- -------------------------- --------
                   1 BACKUP                     EXECUTE

  1 record(s) selected.
