SQL*DBA Compatibility


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


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.log 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>

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.
