shellscript to read data from txt file and import to oracle db
Hi all,
Help needed urgently.
I am currently writing a shellscript to read data/record from a flat file (.txt) file, and import/upload the data to oracle database. The script is working fine, but it takes too long time (for 18000 records, it takes around 90 mins).
I guess it takes so long time to insert to db is because the login to db each time after reading one line of record from txt file (sqlplus -s username/password <<EOF)
login to db each time before insert statement because i want switch the environment to oracle db, after insert, i will exit, so that it will point me back to the backend server to get the dir.txt file.
Is this the correct way?
Is there any way/command to use so that no need to switch between environment? or meaning to say, no need to login to db each time when i want to insert a row of data.
Hope somebody can help as i am newbie to shellscript. thx a lot in advance!!!
