SNAP_GET_CONTAINER_V91 table function - Retrieve tablespace_container logical data group snapshot information

SNAP_GET_CONTAINER_V91 returns table space snapshot information from the tablespace_container logical data group.

Note: This table function has been deprecated and replaced by the SNAPCONTAINER administrative view and SNAP_GET_CONTAINER table function

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

Syntax

The schema is SYSPROC.

Table function parameters

dbname

An input argument of type VARCHAR(128) that specifies a valid database name in the same instance as the currently connected database. Specify a database name that has a directory entry type of either "Indirect" or "Home", as returned by the LIST DATABASE DIRECTORY command. Specify NULL or empty string to take the snapshot from the currently connected database.

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 dbname is not set to NULL and dbpartitionnum is set to NULL, -1 is set implicitly for dbpartitionnum. If this input option is not used, that is, only dbname is provided, data is 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 both dbname and dbpartitionnum are 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_CONTAINER_V91 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_CONTAINER_V91 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.

Example

Retrieve details for the table space containers on the currently connected database on the currently connected database partition.

SELECT SNAPSHOT_TIMESTAMP, TBSP_NAME, TBSP_ID, CONTAINER_NAME, 
   CONTAINER_ID, CONTAINER_TYPE, ACCESSIBLE 
   FROM TABLE(SNAP_GET_CONTAINER_V91('',-1)) AS T
