【ORACLE21C】Oracle21c产品目录的变化

作者：互联网

在Oracle21c之后，一些目录发生了变化，如监听配置文件、dbs目录。 示例如下：

Oracle21c安装之后，目录如下

  1. #$ORACLE_BASE目录下
  2. admin audit cfgtoollogs dbs diag homes oradata product
  3. [oracle@oracle21 oracle]$ pwd
  4. /u01/app/oracle
  5. # 19c $ORACLE_BASE目录下。ASM
  6. [oracle@rac19c oracle]$ ls
  7. admin audit cfgtoollogs checkpoints diag product
  9. #检查Oracle21c目录
  10. [oracle@oracle21 oracle]$ orabasehome
  11. /u01/app/oracle/homes/OraDB21Home1
  12. [oracle@oracle21 oracle]$ orabaseconfig
  13. /u01/app/oracle
  14. [oracle@oracle21 oracle]$
  15. #检查19c目录
  16. [oracle@rac19c ~]$ orabasehome
  17. /u02/app/oracle/product/19.0.0/db_1
  18. [oracle@rac19c ~]$ orabaseconfig
  19. /u02/app/oracle/product/19.0.0/db_1
  20. [oracle@rac19c ~]$ orabase
  21. /u02/app/oracle
  22. [oracle@rac19c ~]$
  24. #检查21c监听状态及文件位置,如下所示，已经在/homes/OraDB21Home1/network/admin/listener.ora目录下，配置tnsnames也需要在该目录下
  25. [oracle@oracle21 oracle]$ lsnrctl stat

检查数据库中一些信息

  1. --检查spfile文件,已不在原来的ORACLE_HOME目录下
  2. SQL> show parameter spfile
  4. NAME TYPE VALUE
  5. ------------------------------------ ----------- ------------------------------
  6. spfile string /u01/app/oracle/dbs/spfilemydb21.ora
  7. SQL>

虽然Oracle21c中想变化为只读目录，但目前查看目录权限，仍然可写。 权限如下：

  1. SQL> Disconnected from Oracle Database 21c Enterprise Edition Release 21.0.0.0.0 - Production
  2. Version 21.3.0.0.0
  3. [oracle@oracle21 oracle]$ pwd
  4. /u01/app/oracle
  5. [oracle@oracle21 oracle]$ ls -lrt
  6. total 32
  7. drwxr-xr-x. 3 oracle oinstall 4096 Aug 19 16:18 product
  8. drwxrwxr-x. 23 oracle oinstall 4096 Aug 19 16:35 diag
  9. drwxr-x---. 3 oracle oinstall 4096 Aug 19 16:35 homes
  10. drwxr-x---. 5 oracle oinstall 4096 Aug 19 16:42 cfgtoollogs
  11. drwxr-x---. 3 oracle oinstall 4096 Aug 19 16:53 admin
  12. drwxr-x---. 3 oracle oinstall 4096 Aug 19 16:53 oradata
  13. drwxr-x---. 3 oracle oinstall 4096 Aug 19 16:55 audit
  14. drwxr-x---. 2 oracle oinstall 4096 Aug 20 13:53 dbs
  15. [oracle@oracle21 oracle]$

目前Oracle21c已经将一些目录分离出来，权限管理可以越来越细化，更好保障数据库的安全，后续继续测试。
