SNAPUTIL_PROGRESS administrative view and SNAP_GET_UTIL_PROGRESS table function - Retrieve progress logical data group snapshot information

The SNAPUTIL_PROGRESS administrative view and the SNAP_GET_UTIL_PROGRESS table function return snapshot information about utility progress, in particular, the progress logical data group.

SNAPUTIL_PROGRESS administrative view

Used in conjunction with the SNAPUTIL administrative view, the SNAPUTIL_PROGRESS 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_PROGRESS administrative view
CONTROL privilege on the SNAPUTIL_PROGRESS administrative view
DATAACCESS authority

In addition, one of the following privileges or authorities is also required:

EXECUTE privilege on the SNAP_GET_UTIL_PROGRESS 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 details on total and completed units of progress by utility ID.

SELECT UTILITY_ID, PROGRESS_TOTAL_UNITS, PROGRESS_COMPLETED_UNITS, 
   DBPARTITIONNUM FROM SYSIBMADM.SNAPUTIL_PROGRESS

The following example is a sample output from this query.

UTILITY_ID PROGRESS_TOTAL_UNITS PROGRESS_COMPLETED_UNITS DBPARTITIONNU
---------- -------------------- ------------------------ -------------
         7                   10                        5             0
         9                   10                        5             1

SNAP_GET_UTIL_PROGRESS table function

The SNAP_GET_UTIL_PROGRESS table function returns the same information as the SNAPUTIL_PROGRESS administrative view, but allows you to retrieve the information for a specific database on a specific database partition, aggregate of all database partitions or all database partitions.

Used in conjunction with the SNAP_GET_UTIL table function, the SNAP_GET_UTIL_PROGRESS 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_PROGRESS--(--+----------------+--)------------><
                              '-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_PROGRESS 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_PROGRESS 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 details on the progress of utilities on the currently connect partition.

SELECT UTILITY_ID, PROGRESS_TOTAL_UNITS, PROGRESS_COMPLETED_UNITS, 
   DBPARTITIONNUM FROM TABLE(SNAP_GET_UTIL_PROGRESS(-1)) as T

The following example is a sample output from this query.

UTILITY_ID PROGRESS_TOTAL_UNITS PROGRESS_COMPLETED_UNITS DBPARTITIONNUM
---------- -------------------- ------------------------ --------------
         7                   10                        5              0
