根据Catupgrd.sql Fails with ORA-3113/ORA-7445 During Grant Select On ALL_JOBS to Public with Grant Option (Doc ID 419309.1)文档,处理建议

1. Make sure LD_LIBRARY_PATH or LIBPATH is set correctly:
  AIX
  ====
  export LIBPATH=$ORACLE_HOME/lib:$LIBPATH
  HP-UX
  =====
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib
  export SHLIB_PATH=$ORACLE_HOME/lib32
  HP Tru-64
  ========
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib
  SUN Sparc Solaris-64Bit
  ==================
  export LD_LIBRARY_PATH_64=$ORACLE_HOME/lib
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib32
  SUN Sparc Solaris-32Bit
  ==================
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib
  Linux
  =====
  export LD_LIBRARY_PATH=$ORACLE_HOME/lib
2. Make sure ORA_NLS parameter  is set correctly. See the following notes for assistance:
Note 77442.1  (ORA_NLS32, ORA_NLS33, ORA_NLS10) Environment Variables explained.
3. Make sure Listener is also started with the correct environment variables if you were doing
  remote connection from client through sqlnet rather than local connection to database.
4. Shutdown the database and rerun the upgrade:
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP UPGRADE
SQL> SPOOL patch.log
SQL> @?/rdbms/admin/catupgrd.sql
5.  If the above failed then it might be due to the libjox *.a file is not replaced during upgrade or install.

检查该环境发现libjox动态库丢失

由于软件升级不正常,导致数据库升级出现该问题,在升级软件过程中,一定检查升级软件和升级结果

PostgreSQL备份工具pg_rman安装

学习oracle的同学都清楚,oracle的rman是最好的备份工具(一般第三方备份软件也基本上是通过调用rman的备份接口实现的)
pg_rman下载地址https://github.com/ossc-db/pg_rman/releases,下载和当前pg版本/操作系统版本对应的pg_rman包

PostgreSQL模式理解

在PostgreSQL中schema和oracle中不一样,在oracle中schema基本上可以理解为user,但是在PostgreSQL中user和schema没有严格意义上的对应关系.
创建模式
这里可以看到使用u_xifenfei创建的schema就是属于该用户,默认的public schema属于postgres用户.

db_xifenfei=# \c
您现在已经连接到数据库 "db_xifenfei",用户 "u_xifenfei".
db_xifenfei=# create schema u_xifenfei;
CREATE SCHEMA
db_xifenfei=# \dn
      架构模式列表
    名称    |   拥有者
------------+------------
 public     | postgres
 u_xifenfei | u_xifenfei
(2 行记录)

数据库检索schema的顺序
默认情况下优先检索和用户名一致的schema,然后是public schema

db_xifenfei=# show search_path;
   search_path
-----------------
 "$user", public
(1 行记录)

测试schema的检索顺序
这里比较明显优先使用/找到的是u_xifenfei schema(和用户名匹配的schema),然后再是默认的public schema

db_xifenfei=# create table t_xifenfei as select * from pg_database;
SELECT 4
db_xifenfei=# select pg_relation_filepath('t_xifenfei');
            pg_relation_filepath
---------------------------------------------

PostgreSQL的表空间、数据库、用户之间的关系

玩多了Oracle,习惯了使用Oracle的体系架构去对比别的数据库,今天看PostgreSQL发现两者明显不一样:
1. 在数据库/表空间/schema三者关系上的区别
20180803011116


表空间是物理结构,同一表空间下可以有多个数据库
数据库是逻辑结构,是表/索引/视图/存储过程的集合,一个数据库下可以有多个schema
模式是逻辑结构,是对数据库的逻辑划分
2. 在oracle中用户和schema基本上可以画上等同关系,但是pg中两者没有这样严格的对应关系

相关测试实验
创建用户
在pg中role比user少login,其他基本上相同(也就是说如果给role授权login,等同user)

postgres=# CREATE USER u_xifenfei WITH
postgres-# LOGIN
postgres-# SUPERUSER
postgres-# CREATEDB
postgres-# CREATEROLE
postgres-# INHERIT
postgres-# REPLICATION
postgres-# CONNECTION LIMIT -1
postgres-# PASSWORD 'xifenfei';
CREATE ROLE

创建表空间

postgres=# CREATE TABLESPACE tbs_xifenfei
postgres-#   OWNER u_xifenfei
postgres-#   LOCATION 'D:\Program Files\PostgreSQL\tbs_xifenfei';
CREATE TABLESPACE

创建数据库

postgres=# CREATE DATABASE db_xifenfei
postgres-#     WITH
postgres-#     OWNER = u_xifenfei
postgres-#     ENCODING = 'UTF8'
postgres-#     TABLESPACE = tbs_xifenfei
postgres-#     CONNECTION LIMIT = -1;
CREATE DATABASE

查询数据库和表空间信息

postgres=# select oid, datname, datlastsysoid, dattablespace
postgres-#  from pg_catalog.pg_database order by 1,2;
  oid  |   datname   | datlastsysoid | dattablespace
-------+-------------+---------------+---------------
     1 | template1   |         12937 |          1663
 12937 | template0   |         12937 |          1663
 12938 | postgres    |         12937 |          1663
 16407 | db_xifenfei |         12937 |         16406
(4 行记录)
postgres=# select oid,* from pg_catalog.pg_tablespace;
  oid  |   spcname    | spcowner | spcacl | spcoptions
-------+--------------+----------+--------+------------
  1663 | pg_default   |       10 |        |
  1664 | pg_global    |       10 |        |
 16406 | tbs_xifenfei |    16405 |        |
(3 行记录)

使用u_xifenfei用户登录

C:\Users\Administrator>psql -U u_xifenfei -d db_xifenfei
用户 u_xifenfei 的口令:
psql (10.4)
输入 "help" 来获取帮助信息.
db_xifenfei=# \c
您现在已经连接到数据库 "db_xifenfei",用户 "u_xifenfei".

创建测试表

db_xifenfei=# create table t_xifenfei as select * from pg_database;
SELECT 5
db_xifenfei=# select pg_relation_filepath('t_xifenfei');
            pg_relation_filepath
---------------------------------------------
 pg_tblspc/16406/PG_10_201707211/16407/16408
(1 行记录)
db_xifenfei=# insert into t_xifenfei select * from t_xifenfei;
INSERT 0 5
…………
db_xifenfei=# insert into t_xifenfei select * from t_xifenfei;
INSERT 0 327680
db_xifenfei=# select count(*) from t_xifenfei;
  count
---------
 1310720
(1 行记录)

这里可以发现,创建表空间其实对应的是一个文件夹路径,创建数据库是在对应的表空间中创建相关目录和文件,创建表是对应的相关文件.

这是一个不常见的错误,没有使用隐含参数强制拉库,数据库正常open成功,但是由于system坏块,导致数据库启动之后报ORA-600 2662错误(再次证明2662不一定只有强制拉库发生,正常open的库也有可能,主要取决block scn和datafile scn,如果不是open过程必须要访问的block,那可能在open之后由于访问需要再报出来该错误).这个问题比较简单,因为open成功之后再crash,而且该坏块引起smon报错但是并没有ora-600 4xxx相关错误,因此根据经验,直接在数据库open之后,处理掉system异常报错对象和坏块对象即可.另外block 2 比较特殊,需要对其上面的对象进行处理
