未提交的上下文

当在系统中创建新的实体时，与新实体关联的上下文通常以未提交状态创建。例如，通过从 configuration alerts threshold 上下文中执行 create 命令来创建Chapter 9, 警报配置：

dory:> configuration alerts thresholds create 
dory:configuration alerts threshold (uncommitted)> 

提示符中的 (uncommitted) 表示这是一个未提交的上下文。未提交的实体通过 commit 命令提交；从未提交的上下文导航到其他位置的任何尝试都将提示进行确认：

dory:configuration alerts threshold (uncommitted)> cd /
Leaving will abort creation of "threshold". Are you sure? (Y/N) 

当提交未提交的实体时，将验证与新实体关联的属性，如果无法创建实体，则将生成错误。例如，创建新阈值警报需要指定统计信息名称；不设置该名称会导致错误的发生：

dory:configuration alerts threshold (uncommitted)> commit
error: missing value for property "statname"

要解决此问题，请修正错误，然后重新尝试提交：

dory:configuration alerts threshold (uncommitted)> set statname=cpu.utilization  
                     statname = cpu.utilization (uncommitted)
dory:configuration alerts threshold (uncommitted)> commit
error: missing value for property "limit"
dory:configuration alerts threshold (uncommitted)> set limit=90
                        limit = 90 (uncommitted)
dory:configuration alerts threshold (uncommitted)> commit
dory:configuration alerts thresholds> list
