linux - 获取错误 : unrecognized configuration parameter "gp_strict_xml_parse" while restoring backup to 5. x Greenplum DB

Question

我目前使用的是 4.3.0 GreenPlum 版本，现在我想升级到最新的 5.8.0 GreenPlum 版本。因为，我的旧设置包含很多数据，我想备份和恢复数据。

为了备份，我在我的 4.3.0 Greenplum 机器上运行了以下命令:

gp_dump --gp-d <Backup Location> <DB_Name>

这条命令执行成功，我得到了命令中指定的数据库的备份。现在，当我运行命令时，即

gp_restore --gp-d <Backup Location> --gp-k <Timestmap Key generated while creating backup> -d <DB_Name>

要在我的 5.8.0 Greenplum 上恢复备份，我收到以下错误:

}

经过一番挖掘，我发现“gp_strict_xml_parse”变量在 GreenPlum 5.x 版本中不再使用。有什么方法可以解决这个问题，或者有什么方法可以在备份数据时不包含这个变量吗？

Answer 1

Greenplum 版本 5.x.x.x 没有 gp_strict_xml_parse 参数。

在😎

在 5.x 及更高版本中恢复时(从 4.3.x 及更高版本创建的备份)您可以在恢复时忽略此错误/警告。因为这些警告不会影响恢复过程。

(注:我试过了，PIVOTAL的文档中也有提到)
