Teradata Parallel Data Pump

Chapter 2: Using Teradata TPump
Estimating Space Requirements
S = Each SQL statement issued through the support environment
L = Each BEGIN/END LOAD command pair
D = Each DML statement
C = Estimated number of checkpoints
P = Packfactor
N = Number of partial checkpoints
Space Calculation Example
The following example of how Teradata TPump log table space is derived takes a simple load
that consists of the following script:
LOGTABLE CME.TLddNT14H;
.LOGON OPNACC1/CME,CME;
DROP TABLE TBL14TA;
DROP TABLE TBL14TB;
DROP TABLE tlnt14err;
CREATE TABLE TBL14TA,FALLBACK
(ABYTEINT BYTEINT,
ASMALLINT SMALLINT,
AINTEGER INTEGER,
ADECIMAL DECIMAL (5,2),
ACHAR CHAR (5),
ABYTE BYTE(1),
AFLOAT FLOAT,
ADATE DATE)
UNIQUE PRIMARY INDEX (ASMALLINT);
CREATE TABLE TBL14TB,FALLBACK
(ABYTEINT BYTEINT,
ASMALLINT SMALLINT,
AINTEGER INTEGER,
ADECIMAL DECIMAL (5,2),
CHAR CHAR (5),
ABYTE BYTE(1),
AFLOAT FLOAT,
ADATE DATE)
UNIQUE PRIMARY INDEX (ASMALLINT);
