开发提出须要从Greenplum同步到Oracle的解决方式，写了个脚本用于定时调度处理。

#!/bin/sh

#copy_gp_2_ora.sh

if [ $# -ne 1 ]; then

    echo "Usage: sh $0 tablename"

    exit 1

fi

TABLENAME=$1

 

psql -h <host> -U <user> <db><<EOF 

\timing off

set client_encoding='gb18030';

\copy $TABLENAME to '/home/oracle/$TABLENAME.txt' csv

\q

EOF

 

echo "load data

infile '$TABLENAME.txt' discardfile '$TABLENAME.dis'

append

into table $TABLENAME

fields terminated by ','

optionally enclosed by '\"'

(id)">"$TABLENAME.ctl"

 

sqlldr system/000000 control="$TABLENAME.ctl" log="$TABLENAME.log"

-EOF-
