There are three packages that the user can install:
Easy Install:
Installs all files.
Custom Install:
* Oracle 2.1 - installs all files (does the same thing as Easy Install package, but if you add any files, you'll have to add them to each package individually).
* tnsnames - backs up the current tnsnames.ora file, and downloads a new one. This is also done in the other packages, but this single file will need to be updated in the future, so we're providing a way to get a new copy of just it without reinstalling everything.
No files have any settings for "Before install" or "Gestalts".

(1) The first thing the installer does is look for a folder named "Oracle 1.5" on the disk the user has chosen to install to (with a Find action item). If it finds one, it displays a message (with a Message action item) asking the user if they want to delete the older version; the default answer is "No". If the user answers "OK", VISE moves the Oracle 1.5 folder to the Trash (it doesn't actually delete the files right then and there).
There is no real conflict between 1.5 and 2.1, and some applications/databases still require 1.5, which is why we offer a chance to remove the older version, but don't force it on the user. Our detection method will fail if the user has renamed the 1.5 version's folder from its default name, but there's not a lot else we can do.
(2) The installer will place a folder called "Oracle Folder" into the Preferences folder, and inside that put an "Oracle Preferences" file.
(3) Then the main Oracle folder and files are installed. Special actions are performed for several files:
config.ora -
The installer checks for an existing "config.ora" file on the users's drive and will rename it to "config.ora.bak" (with a Rename action item). This is because this file is marked to Always Install, so we want to backup the user's current file just in case they made modifications to it (unlikely).
The config.ora file is set to Always Install because this is the only way to guarantee that the SetHome21 code resource, which the installer is told to run after installing "config.ora", will always be run. The SetHome21 code resource puts the path to this file into the "Oracle Preferences" file installed earlier.
sqlnet.ora -
Like "config.ora", this file is backed up (to "config.ora.bak") because it's marked to Always Install.
The sqlnet.ora file is set to Always Install because this is the only way to guarantee that the SqlnetEncryptionSeed code resource, which the installer is told to run after installing "sqlnet.ora", will always be run. The SqlnetEncryptionSeed code resource replaces the encryption seed line in the installed sqlnet.ora file with a new, randomly-generated one.
tnsnames.ora -
Like "config.ora" and "sqlnet.ora", this file is backed up (to "tnsnames.ora.bak") because it's marked to Always Install. However, this time this is because we expect users may reinstall this file from time-to-time as updated versions of it are released.
All other files in the installer are marked to run the FTP code resource after installation to fetch the real files.
(4) Finally, the installer creates an alias to the installed "Libraries" folder and places it in the user's Extensions folder with the name "Oracle Libraries" (with an Alias action item). This is necessary so that Oracle can find the shared libraries it uses. (First a Delete action item is run to get rid of any existing alias because the Alias action item won't create a new one if one already exists.)
The SIZE resource of the installer is set to 1200K, since in testing we discovered that the default allocation of 640K wasn't enough on some machines.
