客户装好了Oracle，安装成功了，但是运行dbca和netca都出现错误。 [oracle@db1 ~]$ netca
Oracle Net Services Configuration: # # An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0xa44b13a8, pid=2973, tid=3086891216 # # Java VM: Java HotSpot(TM) Client VM (1.5.0_17-b02 mixed mode) # Problematic frame: # C [libnnz11.so+0x3c3a8] # # An error report file with more information is saved as hs_err_pid2973.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # /u01/app/oracle/product/11.2.0/dbhome_1/bin/netca: line 178: 2973 Aborted $JRE $JRE_OPTIONS -classpath $CLASSPATH oracle.net.ca.NetCA $*
客户机环境 OS: RHEL AS 4 (32bit) Oracle: Oracle 11g release 2(11.2.0.1)
很明显是JVM导致的问题。
查看hs_err_pid2973.log 里面是JVM的error stack

没有明确的信息
检查java的路径和版本 [oracle@db1 download]$ java -version java version “1.5.0_17″ Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_17-b02) Java HotSpot(TM) Client VM (build 1.5.0_17-b02, mixed mode) 是正确的，所以并不是java的路径导致的。
在otn和oracle forum里找了一下相关信息，有类似的问题，但是都没有明确的答复 猜测是bug导致的。
在metalink上搜索了一下。
找到类似的问题，确定是bug
[ID 942076.1] X86 DBCA, NETCA GIVE JAVA HOTSPOT ERROR IF ON X86_64 HARDWARE [ID 942076.1] You are encountering published Bug 8930861, “X86 DBCA, NETCA GIVE JAVA HOTSPOT ERROR IF ON X86_64 HARDWARE”
You have Oracle’s 32-bit 11.2.0.1.0 RDBMS software, a supported 32-bit Linux OS, but you are on 64-bit x86_64 hardware.
the command “cat /proc/cpuinfo” shows: model name : Quad-Core AMD Opteron(tm) Processor 2356
Solution 1. Please find out if there is any business reason that the 64-bit hardware is only running a 32-bit OS. If not, then Oracle recommends that you re-install a 64-bit OS and 64-bit Oracle to avoid published Bug 8930861, “X86 DBCA, NETCA GIVE JAVA HOTSPOT ERROR IF ON X86_64 HARDWARE”
2. If there is some business reason that you must use 64-bit hardware running a 32-bit Linux OS, then before you can use the 11gR2 DBCA or NETCA tools, you will need to apply patch 8670579 , “NETCA/DBCA FAILED WITH HOTSPOT VIRTUAL MACHINE”. You will be downloading and using file p8670579_112010_LINUX.zip
客户确实是64bit的机器，但是由于版本限制和其他的一些限制，只能装了32位的系统，从而导致这个问题。
cd到目录8670579，执行命令：
8670579]$ /oracle/app/ora11g2/product/11.2.0/dbhome_1/OPatch/opatch apply
Apply patch p8670579搞定。
