Objective Recently do projects need to import a batch of 3000多万条 POI data to Oracle database, simple insert import speed is too slow, use SQLLDR batch import 3000多万条 data spent 20 minutes, speed can also, now share to everyone, the specific methods are as follows: 1. New import Control file Input.ctl, file contents as follows: Load data Characterset UTF8 Infile ' H:\POI\baidu.txt ' Append into tab

old data, insert new,truncate----> Clear table First, then insert. General error: For example: column not found before logical record ends (using TRAILING nullcols) Indicates the number of columns in your control file that do not match the number of columns in the data file , and has not specified trailing nullcols parameter, which prevents some columns from being inserted, first check the control file and data file, and then consider whether you need to add Parameters.

Sqlldr is a recommended method for processing large data volumes. It has many performance switches to minimize redo and undo generation, control Data Processing Methods (insert, append, replace, truncate) Because the project needs to compare the performance of datapump, it is still not ideal, so we still want to use sqlldr. I did a simple test. According to thomas kyte, the fastest way to load parallel exec
