Start Schema Benchmark （SSB）数据生成及脚本

SSB 类似于TPC-H，非常适合测试分析型查询，也非常适合体现Oracle Database In-Memory的优势。

生成示例数据：

git clone https://github.com/electrum/ssb-dbgen.git
cd ssb-dbgen
sed -i 's/^MACHINE.*=.*/MACHINE=LINUX/' makefile		# 将平台改为LINUX
make													# 生成可执行程序dbgen

# 利用dbgen生成示例数据，-T指定表，-s指定数据放大系数
./dbgen -s 8 -T c									# CUSTOMER表
./dbgen -s 24 -T p									# PART表
./dbgen -s 8 -T s									# SUPPLIER表
./dbgen -s 1 -T d									# DATE_DIM表
./dbgen -s 2 -T l									# LINEORDER表

生成表结构：

$ cat create_ssb_schema.sh
#!/bin/bash
# this script will create user SSB and 5 SSB schema tables under it
# you should input password for new created SSB user

read -sp "Please input password for user SSB you will create:" SSBPassword

echo

sqlplus / as sysdba <<-EOF

ALTER SESSION SET CONTAINER = orclpdb1;

DROP USER ssb CASCADE;

CREATE USER ssb IDENTIFIED BY "$SSBPassword";

GRANT dba, unlimited tablespace TO ssb;

ALTER SESSION SET CURRENT_SCHEMA = ssb;

使用SQL Loader 导入Oracle数据库，以下为Control File：

$ cat customer.ctl
options (direct=true)
load data
infile 'customer.tbl'
badfile 'customer.bad'
discardfile 'customer.disc'
append
into table  ssb.customer fields terminated by '|'
nullif = blanks
(
C_CUSTKEY ,
C_NAME ,
C_ADDRESS ,
C_CITY ,
C_NATION ,
C_REGION ,
C_PHONE ,
C_MKTSEGMENT
)

$ cat date.ctl
options (direct=true)
load data
infile 'date.tbl'
badfile 'date_dim.bad'
discardfile 'date_dim.disc'
append
into table  ssb.date_dim fields terminated by '|'
nullif = blanks
(
D_DATEKEY ,
D_DATE ,
