篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Oracle 21版Database In-Memory LivaLabs实验（上）相关的知识，希望对你有一定的参考价值。
概述
目前Oracle LiveLabs上关于Oracle Database In-Memory的内容已更新，主要变化为：
- 数据库使用21c
- 增加了对21c原生JSON的实验
- 增加了21c AIM HIGH级别的实验
这个实验的名称为Boost Analytics Performance with Oracle Database In-Memory。
实验帮助在这里。
实验环境描述
实验环境的生成需要约8分钟。这是一个2 OCPU（4 vCPU）, 32G内存的机器。如果自己搭建环境，只需要16GB的内存就够了。

尽管提供了图形化VNC远程连接的方式，但也可以用putty直接登录虚机，这样更方便。方法请参见“Lab 1: Environment Setup”，此不赘述。
数据库版本为21.7，数据库是PDB1，用到了SSB和AIM两个schema:
Connected to:
Oracle Database 21c Enterprise Edition Release 21.0.0.0.0 - Production
Version 21.7.0.0.0
SQL> show pdbs
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 PDB1 READ WRITE NO
SQL> select username from all_users where ORACLE_MAINTAINED != 'Y';
USERNAME
--------------------------------------------------------------------------------
PDBADMIN
AIM
SSB
SSB schema中的5张标准表均启用了压缩，以下命令只是说明，无需运行：
alter table lineorder move compress basic;
alter table part move compress basic;
alter table date_dim move compress basic;
alter table supplier move compress basic;
alter table customer move compress basic;
alter table storage(buffer_pool keep);
同时也都放在了指定的buffer pool中，以下命令只是说明，无需运行：
alter table lineorder storage(buffer_pool keep);
alter table part storage(buffer_pool keep);
alter table date_dim storage(buffer_pool keep);
alter table supplier storage(buffer_pool keep);
alter table customer storage(buffer_pool keep);
这5张表的数据生成可用以下命令：
./dbgen -s 10 -T c
./dbgen -s 10 -T s
./dbgen -s 10 -T p
./dbgen -s 10 -T l
./dbgen -s 1 -T d
然后导入数据后，将lineorder变为分区表，并删除2个分区：
alter table lineorder modify partition by range(lo_orderdate)
(
partition part_1992 values less than ('19930101'),
partition part_1993 values less than ('19940101'),
partition part_1994 values less than ('19950101'),
partition part_1995 values less than ('19960101'),
partition part_1996 values less than ('19970101'),
partition part_1997 values less than ('19980101'),
partition part_1998 values less than ('19990101')
);
alter table lineorder drop partition part_1992;
alter table lineorder drop partition part_1993;
实验2：初始化环境
任务 1：为内存中用例初始化数据库
首先，需要用oracle用户下载实验脚本：
clear
cd ~oracle/labs
rm -rf ~oracle/labs/*
wget -O novnc-inmemory-21c.zip https://objectstorage.us-ashburn-1.oraclecloud.com/p/7lzqJmKirEWwAc-e4XbZhV0A9ZYzqv7jU6HRhADWpR5zbhHb3x3rKjZV3m5ktDD0/n/c4u04/b/livelabsfiles/o/labfiles/novnc-inmemory-21c.zip
unzip -qo novnc-inmemory-21c.zip
rm -f novnc-inmemory-21c.zip
cd inmemory
ls -ltrh
由于此环境的模板有2个CDB，CDB1和CDB2。而我们只需要CDB1，因此需要停掉CDB2：
sudo systemctl stop oracle-database
sudo sed -i -e 's|CDB2.*$|CDB2:/opt/oracle/product/21c/dbhome_1:N|g' /etc/oratab
sudo systemctl start oracle-database
ps -ef|grep ora_|grep pmon|grep -v grep
而方法是在oratab中将CDB2的条目改为N：
$ cat /etc/oratab
CDB1:/opt/oracle/product/21c/dbhome_1:Y
CDB2:/opt/oracle/product/21c/dbhome_1:N
修改~/labs/inmemory目录下，以下两个文件中ssb和aim用户的口令：
$ ls *login.sql
aim_login.sql imlogin.sql
任务 2：启用In-Memory
运行以下脚本，初始化环境变量：
. ~/.set-env-db.sh CDB1
我们来研究下这个脚本，其中有很多值得学习之处，详见其中的中文注释：

接下来设置数据库参数：
connect / as sysdba
alter system set heat_map=ON scope=spfile;
alter system set sga_max_size=8G scope=spfile;
alter system set sga_target=8G scope=spfile;
alter system set db_keep_cache_size=3000M scope=spfile;
alter system set pga_aggregate_target=2500M scope=spfile;
alter system set inmemory_size=3300M scope=spfile;
alter system set inmemory_max_populate_servers=4 scope=spfile;
alter system set inmemory_virtual_columns=enable scope=spfile;
alter system set "_inmemory_64k_percent"=5 scope=spfile;
alter system set "_inmemory_small_segment_threshold"=0 scope=spfile;
alter system set "_optimizer_use_feedback"=FALSE scope=spfile;
alter system set "_imado_enable_coloptim"=FALSE scope=spfile;
查看隐含参数的脚本如下，详见MOS How To Query And Change The Oracle Hidden Parameters In Oracle 10g and Later (文档 ID 315631.1)：
set lines 150
col parameter for a40
col "Session Value" for a20
col "Instance Value" for a20
SELECT a.ksppinm "Parameter", b.KSPPSTDF "Default Value",
b.ksppstvl "Session Value",
c.ksppstvl "Instance Value",
decode(bitand(a.ksppiflg/256,1),1,'TRUE','FALSE') IS_SESSION_MODIFIABLE,
decode(bitand(a.ksppiflg/65536,3),1,'IMMEDIATE',2,'DEFERRED',3,'IMMEDIATE','FALSE') IS_SYSTEM_MODIFIABLE
FROM x$ksppi a,
x$ksppcv b,
x$ksppsv c
WHERE a.indx = b.indx
AND a.indx = c.indx
AND a.ksppinm LIKE '/&1' escape '/'
/
以下是一些关键隐含参数的默认值和说明：
-- _inmemory_small_segment_threshold默认值为64K，表示小于此值的segment不会考虑发布到IMCS
-- _inmemory_64k_percent表示 in-memory area中元数据和数据的分配比例，默认为3比7
-- _imado_enable_coloptim没找到说明，
Parameter Default V Session Value Instance Value IS_SE IS_SYSTEM
---------------------------------------- --------- -------------------- -------------------- ----- ---------
_inmemory_small_segment_threshold FALSE 65536 65536 FALSE IMMEDIATE
_inmemory_64k_percent FALSE 30 30 FALSE FALSE
_optimizer_use_feedback FALSE TRUE TRUE TRUE IMMEDIATE
_imado_enable_coloptim FALSE TRUE TRUE TRUE IMMEDIATE
_optimizer_use_feedback是11g引入的特性，详见以下文章：
- Trivial Research on the Cardinality Feedback on 11gR2
- Adaptive Optimisation ?
- Hidden and Undocumented “Cardinality Feedback”
重启使其生效：
shutdown immediate
startup
exit
实验 3：设置 In-Memory Column Store
此实验的主要脚本执行序列如下，后面会详述：
@01_show_parms.sql
@02_show_sga.sql
@03_im_usage.sql
@04_im_alter_table.sql
@05_im_attributes.sql
每次实验前，都需要执行以下：
. ~/.set-env-db.sh CDB1
进入setup目录，登录数据库：
cd /home/oracle/labs/inmemory/setup
sqlplus ssb/Ora_DB4U@localhost:1521/pdb1
先去除inmemory属性，原文中少了SUPPLIER表：
alter table SSB.DATE_DIM no inmemory;
alter table SSB.PART no inmemory;
alter table SSB.CUSTOMER no inmemory;
alter table SSB.SUPPLIER no inmemory;
alter table SSB.LINEORDER modify partition PART_1996 no inmemory;
alter table SSB.LINEORDER modify partition PART_1998 no inmemory;
alter table SSB.LINEORDER modify partition PART_1995 no inmemory;
alter table SSB.LINEORDER modify partition PART_1997 no inmemory;
alter table SSB.LINEORDER modify partition PART_1994 no inmemory;
查看内存设置：
SQL> @01_show_parms.sql
Connected.
SQL>

SQL>

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
allow_group_access_to_sga boolean FALSE

sga_max_size big integer 8G
sga_min_size big integer 0
sga_target big integer 0
SQL>
SQL> show parameter db_keep_cache_size

heat_map string ON
SQL>
SQL> show parameter inmemory_size
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
inmemory_size big integer 3312M
SQL>
SQL> set echo off
可以看到我们修改了以下的默认参数：
- INMEMORY_SIZE由0改为3300M
- HEAT_MAP由OFF改为ON
- DB_KEEP_CACHE_SIZE由0改为3000M，以便行式内存和列式内存的性能差异。
查看SGA设置，SGA设置为8G，输出显示In-Memory Area已配置：
SQL> @02_show_sga.sql
Connected.
SQL> set numwidth 20
SQL>
SQL> -- Show SGA memory allocation
SQL>
SQL> show sga

Database Buffers 4613734400 bytes
Redo Buffers 7069696 bytes
In-Memory Area 3472883712 bytes
SQL>
SQL> set echo off
SGA 由固定大小、可变大小、数据库缓冲区和重做缓冲区组成。 由于我们设置了 INEMMORY_SIZE 参数，我们还可以看到在 SGA 中分配的 In-Memory Area。
In-Memory 区域被细分为两个池：一个 1MB 的池用于存储填充在 IM 列存储中的实际列格式数据，一个 64KB 的池用于存储有关填充在 IM 列存储中的对象的元数据。 V$INMEMORY_AREA 视图显示了在 IM 列存储中分配和使用的总内存。
SQL> @03_im_usage.sql

1MB POOL 3,252,682,752 0 DONE 3
64KB POOL 201,326,592 0 DONE 3
SQL>
SQL> set echo off
可以看到这两个池的比例为95比5：
SQL> select 3252682752/(3252682752+201326592) from dual;
3252682752/(3252682752+201326592)

通过全表扫描发布到IMCS：

注意 FULL 和 NOPARALLEL 提示。 他们可确保表数据也被读入定义的 KEEP 池。 这仅针对本实验进行，以便我们可以向您展示基于内存的数据库内存列格式与传统行格式的性能比较。 这不是启动 Database In-Memory 填充所必需的。
populate_wait是同步发布的PL/SQL过程，但此处也可以用于查询发布状态：
SQL> @07_populate_wait.sql

SQL> select dbms_inmemory_admin.populate_wait(priority=>'NONE',percentage=>100,timeout=>60) pop_status from dual;
