The schema is SYSPROC.

The SNAPSHOT_AGENT function returns information about agents from an application snapshot.

Table function parameters

dbname
An input argument of type VARCHAR(255) that specifies a valid database name in the same instance as the currently connected database when calling this function. Specify a database name that has a directory entry type of either "Indirect" or "Home", as returned by the LIST DATABASE DIRECTORY command. Specify the null value to take the snapshot from all databases under the database instance.
dbpartitionnum
An input argument of type INTEGER that specifies a valid database partition number. Specify -1 for the current database partition, or -2 for all active database partitions. An active database partition is a partition where the database is available for connection and use by applications.

If the null value is specified, -1 is set implicitly.

If both parameters are set to NULL, the snapshot will be taken only if a file has not previously been created by the SNAPSHOT_FILEW stored procedure for the corresponding snapshot API request type.
