Unlike UNIX oracle apps ,Windows bit different and tricky to clean the old instance .  If your a Windows R12 oracle apps customer this post will be very useful .  Please follow the note to delete the failed/old oracle instance .

How to Remove an Oracle E-Business Suite Release 12 Windows Environment (Metalink Note 567507.1)

Flashback query is not enabled by default and must be turned on in following sequence. We will set retention to 10 hours (600 minutes), set recovery size up to 2 GB in file “/recovery/flashback”:

shutdown immediate;
startup mount;
alter database archivelog;
alter system set DB_FLASHBACK_RETENTION_TARGET=600;
alter system set DB_RECOVERY_FILE_DEST_SIZE=2G;
alter system set DB_RECOVERY_FILE_DEST=’/recovery/flashback’;
alter database flashback on;
alter database open;

Use it at your own risk

print “Deleting Windows Services perl….\n”;
my $cmd =”sc query \”<SERVICE NAME>\” | grep RUNNING | cut -c33-”;
my $ret =`$cmd`;
chomp($ret);
$ret =~ s/^\s+//;
$ret =~ s/\s+$//;

if(“$ret” eq “RUNNING”){
my $cmd = “sc stop \”<SERVICE NAME>\”";
my $rt=system($cmd);
print “Stop service returned $rt…\n”;

while(true){
sleep(5);

my $rt  =  system($cmd);
print “Delete Service returned $rt…\n”;

In 11g database ,”alter system archive log start;” this statement is not working because from the alert logs archive log start is deprecated . So ALTER DATABASE ARCHIVELOG is enough to start archive process .

ARCHIVE LOG START has been deprecated – see ALTER DATABASE ARCHIVELOG

alter table table_name rename to new_table_name;

PL/SQL Native Compilation Without Needing a Third-Party C Compiler

The benefit of PL/SQL native compilation is automatically available with Oracle Database 11g. No third-party software (neither a C compiler nor a DLL loader) is needed.

Little crunch on plsql_native_library_dir parameter for HP-UX Itanium platform  pointing to some existing  directory , PL/SQL native compilation utilise the directory for
compilation .Note : It has point to existing directory otherwise you can see so many failure (HP-UX Itanium specific)

Insight

“6.1 Location of the Memory Mapped Files”
——————————————
When a PL/SQL unit is compiled using PLSQL_CODE_TYPE=NATIVE in Oracle
Database 11g, the resulting machine code is loaded into an operating system
shared memory object before it is copied to the database catalog.
Additionally, when the native code is fetched from the catalog for execution,
it is first loaded into a shared memory object. On HP, these shared memory
objects are memory mapped files, which are staged in a directory
automatically created by Oracle under the dbs subdirectory of the directory
specified by the environment variable ORACLE_HOME. If you need to change the
location of the staging directory, contact Oracle support.
