修改权限

[grid@cat1 ~]$ lsnrctl status | grep -i 5500
(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=cat1)(PORT=5500))(Security=(my_wallet_directory=/u01/app/oracle/product/19.3.0/db_1/admin/whs1/xdb_wallet))(Presentation=HTTP)(Session=RAW))
[root@cat1 ~]$ cd /u01/app/oracle/product/19.3.0/db_1/admin/whs1/xdb_wallet
[root@cat1 xdb_wallet]$ ls -l
total 8
-rw------- 1 oracle asmadmin 3880 Nov 24 2020 cwallet.sso
-rw------- 1 oracle asmadmin 3835 Nov 24 2020 ewallet.p12

如果不修改权限，控制台无法显示登录界面。在两个节点执行下面权限后，再刷新浏览器地址可正常显示：
[root@cat1 xdb_wallet]$ chmod 777 *
[root@cat1 xdb_wallet]$ ls -l
total 8
-rwxrwxrwx 1 oracle asmadmin 3880 Nov 24 2020 cwallet.sso
