libzdb : Missing 64-bit support Error
by Mahajan, Anand 31 Aug '15

31 Aug '15

Hi there, We are using Libzdb database library version 2.8.1 in our iOS application; now we are trying to upload the application using App Loader to iTunes store; we have got following error; 'Missing 64-bit support - Beginning on February 1, 2015 new iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK. Beginning June 1, 2015 app updates will also need to follow the same requirements. To enable 64-bit in your project, we recommend using the default Xcode build setting of "Standard architectures" to build a single binary with both 32-bit and 64-bit code' Following are our project settings; The error message suggested to add 'standard Architecture' to enable 64-bit support in application; upon setting 'arm64' value for 'valid architecture' in project setting; application is displaying following error Undefined symbols for architecture arm64: "_ResultSet_getDouble", referenced from: _getInvProductsFromDB in .o" ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) We are getting undefined symbol error for every API call of libzdb library; Could you please guide us to build the library for default Xcode setting of standard architecture(arm64, arm7,armv7s)? Appreciate your quick response; Thank you!

SQL query timeout for OracleConnection
by Pavlo Lavrenenko 31 Aug '15

31 Aug '15

Hello. I've noticed query timeout for Oracle connections is a stub, seems like OCI API does not provide a way to limit query execution out-of-box. Yet I am trying to workaround the blocked (server-side) connections issue with DBMail and setQueryTimeout() seems to be a good tool for that. So far I came up with a thread-based solution: 1. a dedicated thread is created for every db connection; 2. thread acts like a watchdog: for every started query it counts down from TIMEOUT value to zero; 3. if query execution is finished the counter is reset and thread idles; 4. if counter reaches 0 the thread calls OCIBreak(). I'd like to know your vision on the solution and reasons why query timeouts are not implemented for Oracle backend before I start the development and publish the patch. TIA. -- Best regards, Pavlo Lavrenenko, PortaOne, Inc., Software Developer Tel: +1-866-SIP VOIP (+1 866 747 8647) ext. 7624 PortaOne - VoIP Solutions Company Visit our Website: http://www.portaone.com
