两节点的DMDSC下，
1、dmarch.ini中本地归档路径和远程归档路径是交叉配置

2、dmarch.ini常见配置
节点0

ARCH_WAIT_APPLY = 0
ARCH_LOCAL_SHARE = 1
ARCH_LOCAL_SHARE_CHECK=0
[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL
ARCH_DEST = +DMARCH/ARCH/DSC0/arch

3、ARCH_LOCAL_SHARE_CHECK，可选值0或者1
专业解释：当需要将归档放在 ASM 中且需要生成多份 local 归档时，需要将该参数设置为 0，否则启动时会校验归档路径不在 asm 中会导致对端节点无法访问到 remote 归档而启动失败。
简单理解：设置为1会检查本地归档与远程归档是否交叉设置。当然，最新版本测试过已不受这个参数设置影响，数据库启动都会执行交叉检查。
