SNAPDETAILLOG administrative view and SNAP_GET_DETAILLOG table function - Retrieve snapshot information from the detail_log logical data group

The SNAPDETAILLOG administrative view and the SNAP_GET_DETAILLOG table function return snapshot information from the detail_log logical data group.

Important: The SNAPDETAILLOG administrative view and the SNAP_GET_DETAILLOG table function are deprecated and have been replaced by the MON_GET_TRANSACTION_LOG table function - Get log information.
Depending on if you are using the administrative view or the table function, refer to one of the following sections:

SNAPDETAILLOG administrative view

This administrative view allows you to retrieve snapshot information from the detail_log logical data group for the currently connected database.

Used in conjunction with ADMIN_GET_STORAGE_PATHS, MON_GET_DATABASE, MON_GET_HADR, MON_GET_MEMORY_POOL, and MON_GET_MEMORY_SET table functions, the SNAPDETAILLOG administrative view provides information equivalent to the GET SNAPSHOT FOR DATABASE on database-alias CLP command.

The schema is SYSIBMADM.

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

Authorization

One of the following authorizations is required to use the view:
  • SELECT privilege on the SNAPDETAILLOG administrative view
  • CONTROL privilege on the SNAPDETAILLOG administrative view
  • DATAACCESS authority
  • DBADM authority
  • SQLADM authority
  • ACCESSCTRL authority
  • SECADM authority
One of the following is required to use the table function:
  • EXECUTE privilege on the SNAP_GET_DETAILLOG 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 log information for all database members for the currently connected database. 
SELECT SUBSTR(DB_NAME, 1, 8) AS DB_NAME, FIRST_ACTIVE_LOG, 
   LAST_ACTIVE_LOG, CURRENT_ACTIVE_LOG, CURRENT_ARCHIVE_LOG, 
   DBPARTITIONNUM 
   FROM SYSIBMADM.SNAPDETAILLOG ORDER BY DBPARTITIONNUM
The following is an example of output from this query. 
DB_NAME  FIRST_ACTIVE_LOG     LAST_ACTIVE_LOG      ...

SNAP_GET_DETAILLOG table function

The SNAP_GET_DETAILLOG table function returns the same information as the SNAPDETAILLOG administrative view.

Used in conjunction with ADMIN_GET_STORAGE_PATHS, MON_GET_HADR, MON_GET_MEMORY_POOL, and SNAP_GET_DB, the SNAPDETAILLOG administrative view provides information equivalent to the GET SNAPSHOT FOR ALL DATABASES CLP command.

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

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 an empty string to take the snapshot from the currently connected database. Specify a NULL value to take the snapshot from all databases within the same instance as the currently connected database.
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 dbname is not set to NULL and member is set to NULL, -1 is set implicitly for member. If this input option is not used, that is, only dbname is provided, data is 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 both dbname and member 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_DETAILLOG 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_DETAILLOG 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 log information for database member 1 for the currently connected database. 
SELECT SUBSTR(DB_NAME, 1, 8) AS DB_NAME, FIRST_ACTIVE_LOG, 
   LAST_ACTIVE_LOG, CURRENT_ACTIVE_LOG, CURRENT_ARCHIVE_LOG 
   FROM TABLE(SNAP_GET_DETAILLOG('', 1)) AS T
The following is an example of output from this query. 
DB_NAME  FIRST_ACTIVE_LOG     LAST_ACTIVE_LOG      ...
