Write the Oracle set-oriented driver according to UDBC convention. Then, write a Glorp ORM driver based on it. The Pharo version of Glorp already has OraclePlatform, which comes from the VW upstream and presumably works, so it can be used as a reference. There's also Garage which also suppors Glorp. All are available in the Catalogue Browser. STH search shows a project named Garage-Oracle by CraigAllen but 'the page does not exist, sadly.' Pierce

It also depends on how you made the certificate. Note that not all browsers like self-signed certificates. It should work on Linux.

I get an "SSL Exception: accept failed [code:-5]" error. Is it because I have a self-signed cert? Apparently, it's failing on: result := self sslSession accept: in from: 1 to: count into: out.

(ZnSecureServer on: 1443) certificate: '/home/sven/ssl/key-cert.pem'; logToTranscript; start; yourself. I don't know how Teapot is implemented, but it uses Zinc, so somehow it will work. You should figure where/how it creates/starts its ZnServer. Note that this might not run on every platform (it depends on the SSL plugin, I know Linux used to work).

How to use HTTPS (SSL) with Zinc

by horrido

Okay, so I have my nice little Teapot app, but I'd like to run it as HTTPS. As far as I can understand, to do this I must go through Zinc. However, the docs on the web seem rather out of date. For example, I do not have ZnZincServerAdapter (in Pharo 5.0). In the simplest terms, how do I support HTTPS? (I've created my self-signed cert.)

Re: [Pharo-users] [ANN] success story: surgery appointments digitalised

by Ben Coman

Pharo doesn't support C++ directly because of issues with name mangling. For C++ you need something like SWIG. See Ronie's insightful comments here... http://forum.world.st/SWIG-for-Native-Boost-FFI-td4738511.html However OCILIB describes itself as "written in pure ISO C99 code" which is much better for us. A demonstrated working connection would be great. @anyone, If Andrew can get a proof of concept working, what are the best frameworks for it to work with? cheers -ben On Sat, Jun 24, 2017 at 12:25 AM, andrew glynn <aglynn42(a)outlook.com> wrote: > It occurred to me that with the C++ support in Pharo 6 it might be > relatively easy to use this driver https://github.com/vrogier/ocilib to > connect to Oracle.

It occurred to me that with the C++ support in Pharo 6 it might be relatively easy to use this driver https://github.com/vrogier/ocilib to connect to Oracle. I will look into it over the weekend.

If you have question don't hesitate to ask. Implanting more pharo everywhere :) Great to hear of your success here. There must be a massive market like this... "Unfortunately XXX didn't offer a proper interface, so we had to dive into the depths of their data base for reverse engineering, to be able to reconstruct functionalities" and if Pharo's liveness helped in this reverse engineering, that would make a great marketing blog post fro you and Pharo... "How a niche language gives us the superpowers to do what others can't." hehe... Indeed the market is huge. Pharo was of help here but would have been a huge help if an oracle driver would have been existed. The biggest problem so far is that it seems they managed to get mixed character encoding in their database. That is close to impossible to solve. Norbert
