mono linux blob performance issue
Re: mono linux blob performance issue
I'm experiencing a similar problem with slow performance on mono/linux, but normal on windows. Was this issue address outside of the forum? Did the program ever get sent to the individual above?
Re: mono linux blob performance issue
We are working on the test program at the moment.

Excellent, thank you.

Please give us the following information:
1) do you run the code on the same workstation where Oracle server resides?
2) the name and version of your Linux distributive where you run the code
3) the version of Mono installed
4) the versions of your dotConnect for Oracle (x.xx.xxx) and Oracle server (x.xx)

Re: mono linux blob performance issue
1) No, the code runs on a linux virtual machine, the Oracle database I'm connecting to is on a different server, however they are on the same LAN network, so speeds should be intra-network LAN speeds.
2) Ubuntu Server 12.10 (GNU/Linux 3.5.0-17-generic x86_64)
3) Mono JIT compiler version 2.10.8.1 (Debian 2.10.8.1-5ubuntu1)
4)
-Devart.Data.dll (5.0.792.0)
-Devart.Data.Oracle.dll (7.9.333.0)
-Oracle: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
Mind you, the subject says "blob" performance. However this extends to all over-the-wire data. I can have a simple DataReader be exponentially slower on the aforementioned configuration than on Windows.
Oh and, using the oracle client System.Data.OracleConnection (not Devart) on the exact same box (it is installed), is just as fast as windows. So it's specifically the devart assembly that has the performance issue.
Thanks guys!

Got it, will run and report back the first chance I getShalex wrote:Just sent to the alternative e-mail.
Re: mono linux blob performance issue
I'm still waiting on 'approval' to get a test user setup in our dev oracle environment... Ya know how it is I'm on vacation after today until Monday. I'll check back then.cray wrote:Got it, will run and report back the first chance I get

The output of the mono app was:

I feel like an idiot though, I cannot figure out how to run the delphi program.

Re: mono linux blob performance issue
Please make sure that the project1 file exists in the current directory when you are executing "./project1" (without quotes).
Re: mono linux blob performance issue
It does. See output of ls and my subsequent attempt to run the program below. Do I need something special installed to execute delphi programs?

You're probably trying to run a 32-bit binary on a 64-bit system that doesn't have 32-bit support installed: http://stackoverflow.com/questions/2716 ... g-a-binary. Please install 32-bit support and try again.
