Hi,

is there a plan to create a PL/SQL Developer 64 bit ?

I'am working on Windows 7 64 and Oracle 11i R2 64 bit.

Many thanks and regards
Friedhold

We are working on a 64 Bit version, but we do not yet have a date.

At the moment you will need to install a 32 Bit Oracle11g Client. PL/SQL Developer is a 32 Bit application, so it cannot interface with a 64 Bit Oracle Client.

The 32 Bit Oracle Client can communicate with a 64 Bit Server, even on the same machine if necessary. The 32 Bit client can coexist with a 64 Bit Oracle installation when installed in separate Oracle Home directories.

Hi Marco, any new status on PL/SQL Developer 64 bit?
I followed your instructions and attempted to install Oracle 11g Client 32 bit) on Win 2008-64 bit. The Oracle installation kept abort. Therefore, I could not get PL/SQL Developer to work on this system.
Much appreciate if we get PLS/SQL Developer (64 bit)!

We are working on a 10.0.x 64 Bit version now, bit do not yet have a date.

The easiest way to add a 32 Bit Oracle Client:

1. Download the Oracle 11g or 12c Instant Client.
2. Create an "InstantClient" subdirectory in the PL/SQL Developer installation directory.
3. Unzip the downloaded instant client into this directory.
4. Define a TNS_ADMIN environment variable and set it to the directory where the tnsnames.ora file of your 64 Bit Oracle Client is located (e.g. C:\Oracle\product\11.2.0\client_1\network\admin).
5. Define an NLS_LANG environment variable and set your language, territory and character set (e.g. AMERICAN_AMERICA.WE8MSWIN1252).

To set environment variables you can start the Windows Control Panel, click on "System", "Advanced system settings", "Environment Variables".

Marco:

Can you announce a release date yet for 10.0.x 64 Bit version?

Not yet.

Will a license purchased to the currently-available 32-bit apply to the 64-bit version, once released?

I don't understand why is it so important to have a 64bit PL/SQL Developer? 4Gigs of RAM isn't enough for your daily work, or something else? Because I do not see any reason for such a software (web browser, mail client, office, pl/sql developer, etc) to be a native 64bit application. Video editing, and some very special tasks, where a 4GB memory is a limit, and using 8-16Gb could be much faster, but otherwise, it is not important.
On the other hand, it is better, if the application is a 32bit app, and it means, that memory leaks, flash player, or javascript errors cannot kill the whole machine. I had such memory problems with some websites, and with many opened tabs, and Firefox startet to allocate 3Gigs of memory, it died later, but my PC with 8Gigs of RAM didn't noticed anything. If it were a 64bit app, it could use all the 8Gig memory, making the whole PC unusable. (As it was with Chrome, because chrome launches all browser tabs in a separate process, and this 4Gig limit applies by process).

Just for the usage of 64bit Oracle client.
ATM among all our tools only PLD needs 32bit client.
