See perl database access and my answer Re: perl database access. It would help us to help you better if you tried to state more of the problem instead of trying to feed it piece by piece. It will also help us to provide you with more answers geared towards reaching your goal if you actually read our answers and provide the information needed and do the work that needs to be done.

my actual pb is i need a expert advice in selecting the option whether go ahead with hash from a file or hash from database. Increasing the hardware or rearranging the index can be done to get a faster serach pattern. I have to do the lookup in database only , but i thought accessing databse for such inflow of records will impact performance.SO i though of option of hash from file/database. i my case 2600*100 records/min needs to be lookup and table will have 100k records i am very bad in network area.

Like I said. Don't populate the hash. Use a database. -- See the Copyright notice on my home node. Perl training courses	[reply]

u meant access the database for every lookup that will be more efficient? I am expecting an inflow of data like this 100 file/min 2600 records in each file and this perl script has to execute in every 10-15 mins i have a memory of 64gb.	[reply]
