2.8 创建XML配置文件
需要提前创建安装时使用的配置文件,配置文件里有对应命名和目录结构参数配置。
omm@host-02[~]cat cluster_config.xml
2.9 节点配置互信
配置两个节点omm用户的互信。
2.10 安装前检查

预检查通过后,可以进行下一步安装动作。
2.11 执行安装
指定参数启动数据库,内存、进程和字符集等参数,主节点执行即可。
gs_install -X /home/omm/cluster_config.xml --gsinit-parameter="--encoding=UTF8" --dn-guc="max_process_memory=4GB" --dn-guc="shared_buffers=256MB" --dn-guc="bulk_write_ring_size=256MB" --dn-guc="cstore_buffers=16MB"

2.12 状态检查
安装完成后执行gs_om命令检查状态。

2.13 备库只读
设置备库只读。
1)如果主备机上的openGauss数据库实例正在运行,请先分别停止主备机上的数据库实例。
2)分别打开主机与备机的postgresql.conf配置文件,找到并将对应参数修改为:
wal_level=hot_standby hot_standby = on hot_standby_feedback = on
3)参数max_standby_streaming_delay、 max_prepared_transactions、 max_standby_archive_delay、 hot_standby_feedback可以参考《数据库参考》按需进行设置。
4)修改完成后,分别启动主备机即可。
2.14 取消public 权限
创建用户后,取消public权限,同时创建一个与用户名相同的schema,创建对象默认放到该schema下。
revoke all on schema public from public; create user user1 login identified by "passwd1"; grant all privileges on database db1 to user1;
2.15 高可用切换测试
进行主备切换测试,以及主备故障恢复测试。
## 切主操作。

-
DBI-1.643.tar.gz
-
DBD-Pg-3.18.0.tar.gz
#在安装前需要设置环境变量:

#分别解压后,执行:
perl Makefile.PL make && make install
# 安装JSON:
JSON-4.10.tar.gz perl Makefile.PL make && make install
## 源码安装:
perl Makefile.PL make && make install export PERL5LIB=/home/omm/software/ora2og/openGauss-tools-ora2og-master/ export PATH=$PATH:/usr/local/bin/ ora2pg --help
root@host-01[/home/omm/software]ora2pg -v Ora2Pg v21.1
3.2 软件环境检查
使用下面提供的脚本检查当前安装组件是否正确。
vi check.pl #!/usr/bin/perl use strict; use ExtUtils::Installed;
my $inst=ExtUtils::Installed->new(); my @modules=$inst->modules();
foreach(@modules) { my $ver = $inst->version($_)||"????"; printf("%-12s -- %s\n", $_, $ver); } exit;

3.3 项目初始化
Ora2pg可以针对每次迁移任务创建一个逻辑项目,项目下有对应目录存放迁移过程中的数据和文件。
root@host-01[/home/omm/ora2pg]ora2pg --init_project dir1
Creating project dir1. ./dir1/ schema/ dblinks/ directories/ functions/ grants/ mviews/ packages/ partitions/ procedures/ sequences/ synonyms/ tables/ tablespaces/ triggers/ types/ views/ sources/ functions/ mviews/ packages/ partitions/ procedures/ triggers/ types/ views/ data/ config/ reports/
Generating generic configuration file Creating script export_schema.sh to automate all exports. Creating script import_all.sh to automate all imports.
3.4 编辑配置文件
