UTILITIES

A utility is nothing but an application (or) a script (or) collection of statements As a block, it is a tool, which LOADS And UNLOADS The Data There many utilities available our of them the very important are:

BTEQ- Load/Unload

FAST LOAD-LOAD

MULTI LOAD-LOAD

TPUMP-LOAD

TPT[Tera data-parallel Transporter]- Load/Unload

TPT API- Load/unload

OLE LOAD- LOAD/UNLOAD

Etc.  

Utility Modes

Every Utility RUNS in 2ways

  • Interactive mode
  • Batch mode

a) Interactive mode

Here one by one statement executed after opening the utility window  

b) Batch mode

2Collection of statements as a script executed here

2live open an editor like a note pad, word pad, etc. and writes the collection of statement

2We can save this script any extension[Tat.ddt, out, etc]But tera data Recommending the below extension to differentiate one script from another script  

Utility Execution

There are 3 ways:

  1. Open the utility and run one by one statement
  2. Go to the corresponding utility and execute the utility script Run command Run File= <File name>;
  3. This is the standard way

IN WINDOWS

BTEQ Start  2 Run  2 cmdàBTEQ<[Script path]>[Log file path]

FLOAD -   Start  2 Run  2 cmd 2 FLOAD LOAD<[Script path]>[Log file path]

TPUMP -   Start  2 Run 2 cmd 2 TPUMP <[Script path]>[Log file path]

FEXP -   Start  2 Run  2 cmd  2FEXP <[Script path]>[Log file path]

Mload - Start  2 Run  2 cmd  2 Mload <[Script path]>[Log file path]  

IN UNIX

BTEQ -    $Sh> BTEQ<[ Script path]/TEE< LOGFILE PATH >(OR)

BTEQ -    $Sh> BTEQ<[ Script path >[LOG FILE PATH]

FLOAD -    Sh> FASTLOAD<[ Script path]/TEE< LOGFILE PATH >(OR)

FLOAD -    $Sh> FASTLOAD <[ Script path >[LOG FILE PATH]

MLOAD -    $Sh> Mload <[ Script path]/TEE< LOGFILE PATH >(OR)

MLOAD -    $Sh> Mload <[ Script path >[LOG FILE PATH]

TPUMP -   $Sh> TPUMP <[ Script path]/TEE< LOGFILE PATH >(OR)

TPUMP -    $Sh> TPUMP <[ Script path >[LOG FILE PATH]

FEXP -    $Sh> FEXP <[ Script path]/TEE< LOGFILE PATH >(OR)

FEXP -    $Sh> FEXP <[ Script path >[LOG FILE PATH]  

Note:

TEE Display the LOG Information on the console  as well as Re- Directs it to the specified file

0 2  Job complete normally

2 2  User alert to Log on to the Tera data DBS

4 2  Working

8 2  User error

12 2  Fatal error[Connection Related Issues possible here]
