gDBClone是一个脚本，用于为测试和开发环境提供一个简单高效的克隆数据库的方法。gDBClone利用Oracle Cloud File System (ACFS)快照功能来创建的数据库副本（能节省很多空间），并管理测试和开发数据库生命周期。这个关键的技术是在Oracle Database 12.1中引入的，受益于ACFS时间点快照功能，我们可以直接在ACFS文件系统上创建Oracle数据库(11.2.0.4以上)。主要提供下面的功能
Clone: Creates a clone database (as Primary or as Standby) from a production database copying the DB to the target test and dev clusterSnap: Creates sparse snapshots of the DB to be used for test and development
Convert: Converts a given database to RAC (Real Application Cluster) OneNode, RAC or from non-CDB (non-container database) to a PDB (pluggable database) of a given CDB
ListDBs: Lists the cloned databases and its snapshots
DelDB: Deletes cloned databases and/or its snapshots
ListHomes: Lists the available oracle home
SYSPwF: Creates an encrypted password file
