以下是一个交互式的 Bash 脚本示例，用于在 Linux 上修改 Oracle 数据库控制文件、日志文件和数据文件的目录。脚本会要求您输入要修改的路径，并根据输入的路径执行相应的修改操作。

#!/bin/bash# 修改以下变量以匹配您的 Oracle 数据库设置
ORACLE_SID="<YOUR_ORACLE_SID>"
ORACLE_HOME="/u01/app/oracle/product/12.2.0/dbhome_1"# 检查运行脚本的用户是否为 Oracle 软件所有者
if [ $(id -u) -ne $(id -u oracle) ]; thenecho "This script must be run as Oracle software owner"exit 1
fi# 函数：获取用户输入的路径
get_path() {read -p "Enter the new path for $1: " pathecho $path
}# 函数：执行 SQL 语句
execute_sql() {echo "Connecting to Oracle database ..."echo "$1" | sqlplus -s / as sysdba# 检查 SQLPLUS 命令是否执行成功if [ $? -ne 0 ]; thenecho "SQL execution failed. Please check the error message and try again."exit 1fi
}# 交互式获取用户输入的路径
new_ctl_path=$(get_path "control file")
new_log_path=$(get_path "log files")
new_data_path=$(get_path "data files")# 切换到 Oracle 软件所有者的家目录
cd $ORACLE_HOME# 使用 SQLPLUS 工具连接到数据库并执行修改 DIRECTORY 的 SQL 语句
execute_sql "alter system set control_files='$new_ctl_path' scope=spfile;"
execute_sql "shutdown immediate;"
execute_sql "startup;"
execute_sql "alter database rename file '$ORACLE_HOME/control01.ctl' to '$new_ctl_path/control01.ctl';"
execute_sql "alter database rename file '$ORACLE_HOME/redo01.log' to '$new_log_path/redo01.log';"
execute_sql "alter database rename file '$ORACLE_HOME/redo02.log' to '$new_log_path/redo02.log';"
execute_sql "alter database rename file '$ORACLE_HOME/redo03.log' to '$new_log_path/redo03.log';"
execute_sql "alter database rename file '$ORACLE_HOME/system01.dbf' to '$new_data_path/system01.dbf';"
execute_sql "alter database rename file '$ORACLE_HOME/sysaux01.dbf' to '$new_data_path/sysaux01.dbf';"
execute_sql "alter database rename file '$ORACLE_HOME/undotbs01.dbf' to '$new_data_path/undotbs01.dbf';"
execute_sql "alter database rename file '$ORACLE_HOME/users01.dbf' to '$new_data_path/users01.dbf';"echo "Oracle database directories have been updated successfully."
exit 0

您只需要运行脚本，然后按照提示输入希望修改的路径，脚本会自动根据您的输入执行相应的修改操作。请注意，在运行脚本之前，请务必备份您的数据库以避免数据丢失。
