X86 DBCA, NETCA GIVE JAVA HOTSPOT ERROR IF ON X86_64 HARDWARE

    在使用DBCA命令创建新的数据库时，DBCA命令无法启动。运行的环境是宿主机64bit+AMD cpu， 而客户机为Linux 32bit + Grid Infrastructure(32) + Oracle database software(32)的情形。原本想着32bit运行的会快一点，没想到Bug 8670579 在执行dbca时再一次被触发，根据Oracel描述，类似的NETCA也会触发这个Bug。 一、故障现象     [oracle@linux1 ~]$ dbca     #     # An unexpected error has been detected by HotSpot Virtual Machine:     #     #  SIGSEGV (0xb) at pc=0x9e0ea498, pid=4242, tid=3086584016     #     # Java VM: Java HotSpot(TM) Server VM (1.5.0_17-b02 mixed mode)     # Problematic frame:     # C  [libnnz11.so+0x3c498]     #     # An error report file with more information is saved as hs_err_pid4242.log     #     # If you would like to submit a bug report, please visit:     #   http://java.sun.com/webapps/bugreport/crash.jsp     #     Aborted     [oracle@linux1 ~]$

二、故障描述     #MeatLink [ID 942076.1]给出了关于这个问题的描述，那就是在客户机上安装了32bit的操作系统与Oracle，而宿主机硬件为64bit平台     #该现象为一个Oracle Bug，Bug号：8670579

    Applies to:     Oracle Server - Enterprise Edition - Version 11.2.0.0 and later     Linux x86

    Symptoms     After successfully installing 32-bit 11gR2 (11.2.0.1.0) software onto a 32-bit Linux OS (x86) system,  neither netca or dbca can be run:

    Dbca error is:     #     # An unexpected error has been detected by HotSpot Virtual Machine:     #     # SIGSEGV (0xb) at pc=0x9dc0c35e, pid=8292, tid=3086022864     #     # Java VM: Java HotSpot(TM) Server VM (1.5.0_17-b02 mixed mode)     # Problematic frame:     # C [libnnz11.so+0x3c35e]

    Netca error is:     # An unexpected error has been detected by HotSpot Virtual Machine:     #     # SIGSEGV (0xb) at pc=0xa2c2235e, pid=8272, tid=3086309584     #     # Java VM: Java HotSpot(TM) Server VM (1.5.0_17-b02 mixed mode)     # Problematic frame:     # C [libnnz11.so+0x3c35e]

    Other Problematic frame values have also been reported, and include:     [libnnz11.so+0x3c35e]     [ld-linux.so.2+0xc1fc]

    Changes     Although the Linux OS that has been installed is indeed a supported 32-bit Linux OS, the hardware that is being used is 64-bit x86_64 hardware.

    Cause     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

三、解决方案     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 need to download the 11.2.0.1.0 version of the patch     (p8670579_112010_LINUX.zip) and install it.

    #检查本机     [root@linux1 ~]# cat /proc/cpuinfo | grep model     model           : 4     model name      : AMD Phenom(tm) II X4 955 Processor     model           : 4     model name      : AMD Phenom(tm) II X4 955 Processor

    #下载8670579 patch，再使用opatch apply 即可。     #在安装Grid Infrastructure时执行root.sh时也会有出发该bug的情形，最主要的原因应该是对AMD cpu，32bit 平台支持不好。     #因此，宿主机安装在64bit硬件平台，客户机使用32位，需要将该patch应用到Grid Infrastructure，其次也要应用到Oracle database software。     #关于执行root.sh时，会收到Failed to create or upgrade OLR 错误。
