java - Optimizing data inserts for HibernateTemplate -


i have optimize database (especially insert) performance of legacy tool. tool has been written in java , data access layer spring + hibernatetemplate technology of choice.

the actual problem doing bulk inserts. have insert more 50k data calling hibernatetemplate.save() each. apparently inefficient way because of lack of time, cannot change implementation now.

what optimization patterns other changing implementation?

the things can think of, if want optimize code without modifying code :

if you're ready change code, follow the advices of documentation, , regularly flush , clear session while inserting data. or use stateless session.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
