netca 啟動時報錯（Segmentation fault(coredump)）

系統為AIX6.1  oracle 10g ,開啟netca 時出現如下問題：

$ netca

Oracle Net Services Configuration:
JVMDG217: Dump Handler is Processing Signal 11 - Please Wait.
JVMDG303: JVM Requesting Java core file
JVMDG304: Java core file written to /usr/app/oracle/product/10.2.0/network/tools/javacore2359476.1341391537.txt
JVMDG215: Dump Handler has Processed Exception Signal 11.
/usr/app/oracle/product/10.2.0/bin/netca[190]: 2359476 Segmentation fault(coredump)
$ id

uid=400(oracle) gid=206(oinstall) groups=0(system),400(dba)

檢查發現/etc/host裡面沒有配置主機名；

配置主機名和hostname 一致後，重新開啟netca 正常，問題解決。
