OGG: OGG-00446 Oracle GoldenGate Capture for Oracle, extdata.prm: No valid log files for current redo

如题所示的错误，发生在为Oracle RAC配置OGG的时候，启动源端（RAC）的抽取进程。
该错误的详细反馈如下：

造成该错误的原因是因为RAC的共享存储采用了ASM（自动存储管理），而OGG的抽取进程无法连接到ASM，[……]

OGG:ERROR: Could not delete DB checkpoint for REPLICAT REPL

在OGG的配置过程中，可能你会遇到如题的错误。
它的具体场景是，你的OGG中有一个REPLICAT复制进程，但是你希望删掉重新配置：

GGSCI (ogg3) 17> delete replicat REPL  
ERROR: Could not delete DB checkpoint for REPLICAT REPL (Database login required to delete database checkpoint)

GGSCI (ogg3) 17> delete replicat REPL

ERROR: Could not delete DB checkpoint for REPLICAT REPL (Database login required to delete database checkpoint)

解法：
其实，对于REPLICAT这样的进程要执行删除，你需要先“dblogin”才可[……]
