/arch/test 而不是/arch/test/如下测试验证log_archive_dest_1与log_archive_format对生成的归档文件名的影响。
1.log_archive_dest_1指定的目录后面还有字段
1.1. 字段对应的无同名目录,生成归档文件名=log_archive_dest_1+log_archive_format
1.2 字段对应的有同名目录,生成归档文件在同名目录下,文件名为log_archive_format
2.log_archive_dest_1指定的目录不存在--报错
1 log_archive_dest_1指定的目录后面还有字段
1.1. 字段对应的无同名目录,生成归档文件名=log_archive_dest_1+log_archive_format
