Hi,
Also, try this cool glogin script from Chris Foot to show the instance name in your SQL*Plus promt:
COLUMN file_name FORMAT a44
COLUMN tablespace_name FORMAT a20
COLUMN owner FORMAT a15
COLUMN segment_name FORMAT a20
set lines 132
set pages 100
set termout off
col dbname new_value prompt_dbname
select instance_name dbname from v$instance;
set sqlprompt "&&prompt_dbname> "
set termout on
set time on
Here are the set options:
APPI[NFO]ON
Application info for performance monitor (see DBMS_APPLICATION_INFO)
ARRAY[SIZE] {15|n}
Fetch size (1 to 5000) the number of rows that will be retrieved in one go.
AUTO[COMMIT] OFF|n}
Autocommit commits after each SQL command or PL/SQL block
AUTOP[RINT] OFF
Automatic PRINTing of bind variables.(see PRINT)
AUTORECOVERY ON
Configure the RECOVER command to automatically apply
archived redo log files during recovery - without any user confirmation.
AUTOT[RACE] OFF} [EXP[LAIN]] [STAT[ISTICS]]
Display a trace report for SELECT, INSERT, UPDATE or DELETE statements
EXPLAIN shows the query execution path by performing an EXPLAIN PLAN.
STATISTICS displays SQL statement statistics.
Using ON or TRACEONLY with no explicit options defaults to EXPLAIN STATISTICS
BLO[CKTERMINATOR] {.|c|OFF|ON}
Set the non-alphanumeric character used to end PL/SQL blocks to c
CMDS[EP] {;|c|OFF|ON}
Change or enable command separator - default is a semicolon (;)
COLSEP { |text}
The text to be printed between SELECTed columns normally a space.
COM[PATIBILITY] {V5|V6|V7|V8|NATIVE}
Version of oracle - see also init.ora COMPATIBILITY=
You can set this back by up to 2 major versions e.g. Ora 9 supports 8 and 7
CON[CAT] {.|c|OFF|ON}
termination character for substitution variable reference
default is a period.
COPYC[OMMIT] {0|n}
The COPY command will fetch n batches of data between commits.
(n= 0 to 5000) the size of each fetch=ARRAYSIZE.
If COPYCOMMIT = 0, COPY will commit just once - at the end.
COPYTYPECHECK OFF
Suppres the comparison of datatypes while inserting or appending to DB2
DEF[INE] {&|c|OFF|ON}
c = the char used to prefix substitution variables.
ON or OFF controls whether to replace substitution variables with their values.
(this overrides SET SCAN)
DESCRIBE [DEPTH {1|n|ALL}][LINENUM {ON|OFF}][INDENT {ON|OFF}]
Sets the depth of the level to which you can recursively describe an object
(1 to 50) see the DESCRIBE command
ECHO OFF

EMB[EDDED] OFF
OFF = report printing will start at the top of a new page.
ON = report printing may begin anywhere on a page.
ESC[APE] {\|c|OFF|ON}

FEED[BACK] {6|n|OFF|ON}
Display the number of records returned (when rows > n )
OFF (or n=0) turns the display off
ON sets n=1
FLAGGER OFF|FULL}
Checks to make sure that SQL statements conform to the ANSI/ISO SQL92 standard.
non-standard constructs are flagged as errors and displayed
See also ALTER SESSION SET FLAGGER.

HEADS[EP] {||c|OFF|ON}
Define the heading separator character (used to divide a column heading onto > one line.)
OFF will actually print the heading separator char
see also: COLUMN command
INSTANCE [instance_path|LOCAL]
Change the default instance for your session, this command may only be issued when

Earlier versions default to 80, Oracle 9 is 150
LOBOF[FSET] n
Starting position from which CLOB and NCLOB data is retrieved and displayed
LOGSOURCE [pathname]
Change the location from which archive logs are retrieved during recovery

OFF = disable substitution variables and parameters
SERVEROUT[PUT] OFF [SIZE n] [FOR[MAT] {WRA[PPED]|WOR[D_WRAPPED]|TRU[NCATED]}]
