物理dg环境中关于归档的删除疑问
os:Enterprise Linux Enterprise Linux Server release 5.5db:Release 11.2.0.3.0 Production
a为主库,b为物理备库 保护模式:MAXIMUM AVAILABILITY
刚在a上执行rman备份脚本(0级), --------脚本在最后
我想问下,
1.我在a上执行备份后,把归档删除,如果有归档还没在备库上应用,那是不是一起删除了?
2.在10g中与在11g中关于dg环境下归档删除设置是否有区别?
3.在 RMAN backups in Max Performance/Max Availability Data Guard Environment(文档 ID 331924.1)中对闪回内的有设置,那不在闪回区中的归档应该如何配置呢?在联机文档中是否有相关?如有能否指出所在位置?多谢!
rman脚本如下:
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
crosscheck archivelog all;
sql 'alter system archive log current';
backup incremental level 0 database format '/rman/%T_%d_%s_%p_dbf.bak' filesperset = 2;
backup archivelog all delete input format '/rman/%T_%d_%s_%p_arch.bak' filesperset = 40;
backup format '/rman/%T_%d_%s_%p_ctl.bak' current controlfile;
delete noprompt obsolete;
}
