Re: change schema based on environment
Keith, You can specify a default schema in a DB2 connection URL like this: jdbc:db2://mserver:50007/MYDB7T:currentSchema=MySchema; Can you use this syntax when creating the data source?

Re: Build Errors
Hi, Thanks a lot. I made the changes you suggested and successfully done with the build. Now started to look into the code and documentation.

Re: Build Errors
Hi! The problem is that our build opens lots of files: > (Too many open files) Usually your ulimits for open files are set to 1024 if you are on *nix Try opening /etc/security/limits.conf and add the following 2 lines: * hardnofile 4096 * softnofile 4096 Then apply those values with $> sysctl -p and open a new shell environment with $> su - [yourusername] Please check if the new limits got applied with $> ulimit -n LieGrue, strub --- On Sat, 1/8/11, Umashanthi Pavalanathan wrote: > From: Umashanthi Pavalanathan > Subject: Build Errors > To: dev@openjpa.apache.org > Date: Saturday, January 8, 2011, 3:04 AM > Hi devs, > > I checked out the OpenJPA source code from [1] and trying > to build it. > I'm getting build errors due to different class files, in > the OpenJPA > Persistence JDBC component, each time I build. > Following are some of the errors [2] [3] [4]. > > I would be glad if someone can guide me to solve these > build errors. > > > > [1] http://svn.apache.org/repos/asf/openjpa/trunk > [2] http://pastebin.com/SPhnRQyW > [3] http://pastebin.com/78zUeUzE > [4] http://pastebin.com/60gKwfRv > > Thanks, > ~Umashanthi >
