By default, FastLoad errors are logged in Teradata tables named SASFASTLOADERRS1randnum and SASFASTLOADERRS2randnum, where randnum is a randomly generated number. For example, if you specify BLLOG=myloaderrors, errors are logged in tables myloaderrors1 and myloaderrors2.

| Subj: | LSN error using FASTLOAD |
| From: | Duell, Bob |
Hi,
I hope someone can help with a mysterious problem. We use SAS software to interact with Teradata. One feature enables SAS to invoke Teradata's FASTLOAD utility using a native SAS data source to provide rows to be inserted into a table. This has always worked well.
However, we have recently begun getting this error message from SAS:
ERROR: Fastload could not allocate data sessions: Associated LSN was not found.
The closest thing I can find in the Teradata Messages manual is this (from page 6-60):
*3029 Associated LSN was not found.*
*Explanation: *An LSN associate connect request has been received for a host/LSN which cannot be found in the system.
*Generated By: *Session Control.
*For Whom: *Support Representative.
*Notes: *This error is returned by an internal consistency check. This error causes an error message to be returned to the host.
*Remedy: *Check the LSN sent to the DBC to see that it already exists.
The problem cannot be reproduced; running the job a second time loads the table just fine so I assume it has something to do with system congestion or maybe a timing problem.
Can someone please help me diagnose this problem? If I can get a clear explanation on what this error means I may be able to get additional assistance from SAS.
Note: We upgraded the Teradata Utilities on our UNIX server in September, just prior to a system upgrade from V2R5. Our current release is V2R.06.01.01.74. The FASTLOAD version is 07.08.00.05. I don't remember ever seeing this message before upgrading.
Thanks very much,
Bob

FastLoad utility is used to load data into empty tables. Since it does not use transient journals, data can be loaded quickly. It doesn't load duplicate rows even if the target table is a MULTISET table.
Limitation
Target table should not have secondary index, join index and foreign key reference.

How FastLoad Works
FastLoad is executed in two phases.
Phase 1
The Parsing engines read the records from the input file and sends a block to each AMP.
Each AMP stores the blocks of records.
Then AMPs hash each record and redistribute them to the correct AMP.

Phase 2
Phase 2 starts when FastLoad receives the END LOADING statement.
Each AMP sorts the records on row hash and writes them to the disk.
Locks on the target table is released and the error tables are dropped.
Example
Create a text file with the following records and name the file as employee.txt.
Following is a sample FastLoad script to load the above file into Employee_Stg table.

Executing a FastLoad Script
Reference Manual Definition
Once the input file employee.txt is created and the FastLoad script is named as EmployeeLoad.fl, you can run the FastLoad script using the following command in UNIX and Windows.
Once the above command is executed, the FastLoad script will run and produce the log. In the log, you can see the number of records processed by FastLoad and status code.
FastLoad Terms
Following is the list of common terms used in FastLoad script.
LOGON − Logs into Teradata and initiates one or more sessions.
DATABASE − Sets the default database.
BEGIN LOADING − Identifies the table to be loaded.
ERRORFILES − Identifies the 2 error tables that needs to be created/updated.
CHECKPOINT − Defines when to take checkpoint.
SET RECORD − Specifies if the input file format is formatted, binary, text or unformatted.
DEFINE − Defines the input file layout.
FILE − Specifies the input file name and path.
INSERT − Inserts the records from the input file into the target table.
END LOADING − Initiates phase 2 of the FastLoad. Distributes the records into the target table.
LOGOFF − Ends all sessions and terminates FastLoad.
