Compatibility with SQL*DBA

This appendix lists the differences between Oracle7 SQL*DBA and Server Manager DBA commands.

Figure C-1 Functional Differences

Feature	SQL*DBA	Server Manager
DESCRIBE for PL/SQL	Lists information about the procedure argument in a tabular form	Lists the definition of the procedure argument
PRINT <no args>	Does nothing	Prints all defined variables
PRINT (before connect)	SQLDBA> print a DBA-00302: not connected to a database	SVRMGR> print a A ---------- 10
SET CHARWIDTH	Displays a character string equivalent to the number of bytes required. For example, if CHARWIDTH is set to 14 and a two-byte character set is used, seven characters are displayed.	Displays the number of characters specified by CHARWIDTH regardless of the number of bytes used by the character string. For example, if CHARWIDTH is set to 14, 14 characters are displayed.
SET COMPATIBILITY NATIVE	Unsupported	Server Manager uses the native SQL of the database to which you are connected
SHOW <no args>	SQLDBA> show show * DBA-00115: unexpected end of command	Prints current Server Manager settings
SPOOL <no args>	SQLDBA> spool File sqldba.l og opened... No prompt	SVRMGR> spool Name for the spool file: (svrmgr.log) Prompts for a filename. The default is SVRMGR.LOG.
STARTUP	If any step of STARTUP fails, SQL*DBA backs out and leaves the database in a shutdown state.	If any step of STARTUP fails, Server Manager leaves the database in its current state. For example, if an error is encountered after the mount stage, Server Manager leaves the database mounted.
VARIABLE a CHAR	Default size is 1	Default size is CHARWIDTH
@<no args>	SQLDBA> @ ORA-07225: ... Prints an error	SVRMGR> @ Name of script file: Prompts for the name of the file
Empty line	SQLDBA> garbage 2> SQLDBA>; SQLDBA>	SVRMGR> garbage 2> 3>; garbage * ORA-00900: invalid SQL statement SVRMGR>

Figure C-2 Cosmetic Differences

Feature	SQL*DBA	Server Manager
Prompt	SQLDBA>	SVRMGR>
Product Banner	SQL*DBA	Server Manager
Connect to idle instance	SQLDBA> connect internal connected.	SVRMGR> connect internal connected to an idle instance.
PRINT a	A ---------- 10 1 row selected. The variable name is space padded: "A ".	A ---------- 10 The variable name is not space padded: "A" Also, no feedback is listed.
SET	SQLDBA> set echo on SQLDBA>	SVRMGR> set echo on Echo ON SVRMGR> Server Manager echoes the new value
Error Message Prefix	DBA-xxxxx: ...	MGR-xxxxx: ...
Wrapping text	Writes 80 characters and then wraps	Writes the entire width and relies on the display device to deal with wrapping. This is better for wide terminals.
