Hi, I know their are various tools that can take LLVM IR Bitcode and JIT it and execute it. Is there anything that can do the equivalent but at the LL\VM IR Bitcode level? So, that for example, I could set some initial conditions, and then single step through the IR Bitcode function, and pause it and print out any of the SSA values that I wish? Kind Regards James

Is it possible to have a file copied from the fileserver but only when it doesn''t exist? I want to prevent changes on the client from being wiped out if it is different. We have a couple of config files that the DBAs are resistant to managing through puppet. They currently manually deploy changes and I don''t want those changes wiped out if the server isn''t updated. I want the files to be copied initially so the machine is setup even if it has a old version. - Ian

Hi, I need to get the environment variable ORACLE_SID from the OS. I know this can be done with the following: $blah = env("PATH") However, the ORACLE_SID variable is only set under the oracle user account. So I would need a way to login as the oracle account first to retrieve the ORACLE_SID variable. Is there anyway to get the environment variable from a user''s account

Hi All, I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see the same LUNs as serverA? Or does it have to have preexisting, empty LUNs to import the clones? Please...

Hello ! Can you please share your experiences with ZFS deployment for Oracle databases for production usage ? Why did you choose to deploy the database on ZFS ? What features of ZFS are you using ? What tuning was done during ZFS setup ? How big are the databases ? Thank you, Jay

...Database graphic designer that works perfect with Mysql standard tables and the id standard is different from the ID standar name used by Rails. Does not support standard table design, for example the tables shouldn''t have plural names. It''s a long discussion between OO purist and DBAs. Also I found many samples of the developer that showed not Normalized Tables (duplicated fields) in order to make it work quicker I bet. 2. It feels heavy, not so quick. I think is because it adds lots of layers in order to make transparent the database use and some other stuff. 3.It is not easy t...

Hi all, I just watched the rail video: http://www.rubyonrails.org/media/video/rails_take2_with_sound.mov I am just curious. I can tell that the video was done on a Mac, but I cannot tell which applications were used for editing the code, and for interfacing with MySQL database. As far as editing source code, I normally use BBEdit (I''ve used it since 1994), but the editor used in

I''m coming from an Oracle and SQL Server background. I''d like to use OpenSource for my next RoR project. MySQL5.x and Postgres8.1 seem to be the most popular. I''d like some comments on which would be the better choice for a production environment and why. Here are my initial concerns in order of priority: 1. Works well with RoR. ( migrations, etc) 2. Stable enough

I can''t decide where store images for my Rails application. -- Posted via http://www.ruby-forum.com/.

I am starting a large project and still selecting what framework to use. Rather than ask brand x what is wrong with brand y, I am more interested in self confession. Why would I *not* want to use Rails (compared to Iowa and Nitro). I posted a synopsis of the project to ruby-talk but will repost it here if anyone wants it. xev

I have been a user of OCFS2 for quite some time now (2 years or so) and a user of Oracle RAC for several years as well. My usage of these two is completely independent though, the cluster filesystem is for application level usage (web servers, etc.) only because RAC can manage its own shared storage directly. And that brings me to my observation/question... I keep seeing a lot of messages

This is pretty ugly. I''m using puppet to install Oracle, ie an exec{} wrapped around: /u01/oracle_extract/linux.x64_11gR2_database/database/runInstaller -silent -responseFile /etc/oracle_response.rsp The problem is that the damn installer backgrounds itself and returns control to the shell. I tried putting the above command in a script, followed by a wait command, but that

Hi I am looking at open projects that LLVM want to implement and it seems to be a suggestion to write an LLVM IR level debugger. Is there any existing LLVM projects out there that already does such a thing? If not, I would like to try implementing one myself. By debugger, I think it means something like gdb, where you can insert breakpoints, run code and observe layout of registers and memory at

How can I tell if this is normal behaviour? Oracle imports are horribly slow, an order of magnitude slower than on the same hardware with a slower disk array and Solaris 9. What I can look for to see where the problem lies? The server is 99% idle right now, with one database running. Each sample is about 5 seconds. I''ve tried setting kernel parameters despite the docs saying that

...Referential integrity is but one specific case of a whole set of database level integrity constraints (including primary keys, uniqueness constraints, etc.). Few databases support SQL 92 assertions (see http://stackoverflow.com/questions/6368349/why-dont-dbmss-support-assertion), so most developers/DBAs that want more complicated database level integrity constraints implement them via triggers. In addition, triggers can also be used to implement automatic caching of computer or derived data within the database (for instance, updating a table that keeps track of all direct and indirect reporting pa...

Hi all, I want to use puppet to distribute keys to multiple users. I wanted to do something like we have already: - define a key per real person - define groups containing several keys, people can be in multiple groups - deploy these groups of keys to specific users however it looks like the ssh_authorized_key resource ties a key and a user together so it looks like I fall at the first

Hi, when I define a db column to be non-nullable or of length 20 or as numeric, I would expect rails to validate that, but that doesn''t seem to be the case. Any idea why that is? The metadata is accessible, at least in the mysql case. I am using rails 1.0 with mysql 5. Cheers, Mariano
