文档课题：备库归档日志文件的删除测试——第二篇：valid_for参数为ONLINE_LOGFILES与STANDBY_LOGFILES.
数据库：oracle 11.2.0.4
架构：rac(2节点)+dg(orcldg与sh_orcl)
场景描述：在该架构中，orcldg备库作为sh_orcl备库归档日志文件的来源，现测试以下两点：
a、归档日志文件从orcldg备库传输到sh_orcl备库后先不应用，此时orcldg端是否能删除未应用的归档日志？
b、sh_orcl无法接收orcldg端的归档日志，此时在orcldg备库端是否能删除未传输的归档日志？
1、valid_for为ONLINE_LOGFILES,ALL_ROLES
说明：现测试orcldg库valid_for为online_logfiles,all_roles的场景.
1.1、环境准备
--当前orcldg备库log_archive_dest_4配置
SYS@orcldg> show parameter log_archive_dest_4
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_4 string SERVICE=sh_orcl COMPRESSION=EN
ABLE LGWR ASYNC VALID_FOR=(ALL
_LOGFILES,ALL_ROLES) DB_UNIQUE
_NAME=sh_orcl
--修改log_archive_dest_4配置参数，将valid_for修改为ONLINE_LOGFILES,ALL_ROLES
SYS@orcldg> alter system set log_archive_dest_4='SERVICE=sh_orcl COMPRESSION=ENABLE LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=sh_orcl';
System altered.
SYS@orcldg> show parameter log_archive_dest_4
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_4 string SERVICE=sh_orcl COMPRESSION=EN
ABLE LGWR ASYNC VALID_FOR=(ONL
INE_LOGFILES,ALL_ROLES) DB_UNI
QUE_NAME=sh_orcl
SYS@orcldg> alter system set log_archive_dest_state_4=enable;
System altered.
--将主库端log_archive_dest_3置空.
SYS@orcl1> alter system set log_archive_dest_3='' sid='*';
System altered.
说明：以上配置在于主库停止传输归档日志文件到sh_orcl备库，转为由备库orcldg传输归档日志文件到sh_orcl备库.

说明：节点1序列号为354、355、356、357、358，节点2序列号为189、190的归档日志文件为新增，其并未传输到sh_orcl备库.
2.3.2.3、删除测试
--备库orcldg端进行删除测试.

说明：如上所示，orcldg备库端无法删除sh_orcl备库未接收的归档日志文件.
总结：
a、当orcldg备库的valid_for修改为ONLINE_LOGFILES,ALL_ROLES后，新增归档日志文件并不会通过orcldg备库传输到sh_orcl备库.
b、当orcldg备库的valid_for修改为STANDBY_LOGFILES,ALL_ROLES后,orcldg备库端无法删除sh_orcl备库未接收的归档日志文件. 0
