但是在目标库上无法生成pa文件                                     
[oracle@node1 dirdat]$ ls
aa000000  aa000001  aa000002  aa000003  aa000004

在网上查到的资料说可能是因为 目标库上的collector 进程将dirdat文件锁住导致无法生成pa文件，
从而导致资源库  pump进程挂起 。各位大神如果遇到过 这个    问题帮忙看看哦。       
测试
                                                                                                                                                                                                                                                   
拷贝文件到node1            
[oracle@node3 ~]$ scp aaaaaa node1:/home/oracle
oracle@node1's password: 
aaaaaa                             100%    0     0.0KB/s   00:00
但是node1上没有文件                        
[oracle@node1 ~]$ ls
ogg112101_fbo_ggs_Linux_x86_ora11g_32bit.zip       oradiag_oracle       veridata-cagent.zip
Oracle Goldengate 11g Install and Setup Guide.doc  V18156-01-linux.zip  veridata-server.zip
[oracle@node1 ~]$ ls

从新配置/etc/hosts 文件        
[root@node3 ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

192.168.10.11     node3
192.168.10.101    node1
拷贝正常，但是问题没有解决
