Sas Teradata Fastload

Hi, Majestic software dash 8 q400 free download.

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. Target table should not have secondary index, join index and foreign key reference. How FastLoad Works. FastLoad is executed in. Teradata MultiLoad Reference 3 Preface Purpose This book provides information about Teradata MultiLoad, which is a Teradata® Tools and Utilities product. Teradata Tools and Utilities is a group of products designed to work with Teradata Database. Teradata MultiLoad provides an efficient way to deal with batch maintenance of large databases.

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.

• Fastload, the name itself telling that loads data in a fast way.That means it loads huge amount of data from flat file into EMPTY tables. Manily FastLoad was developed to load millions of rows into empty Teradata tables so it is fast.

• Table 20: FastLoad Entering Commands Command. Directs Teradata FastLoad to log on to the Teradata Database for up to four sessions. Directs Teradata FastLoad to begin reading data at record 100 in the input data source and stop reading records at record 100,000.

However, we have recently begun getting this error message from SAS:

ERROR: Fastload could not allocate data sessions: Associated LSN was not found.

Sample Reference Manual

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
