Oracle notes: dbca error C [libnnz11.so + 0x3c3a8]

After Oracle is installed, the installation is successful, but errors occur when dbca and netca are running.

This is obviously a problem caused by JVM.

View hs_err_pid2973.log
There is an error stack of JVM.

No clear information

Check the java path and version
[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)
Is correct, so it is not caused by the java path.

I found related information in otn and oracle forum. I had similar questions, but I didn't give a clear answer.
This is caused by a bug.

Search on metalink.

Find a similar problem and make sure it is a bug.

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: quactive-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
32-bit OS. If not, then Oracle recommends that you re-install a 64-bit OS and 64-bit Oracle
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
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

The customer is indeed a 64bit machine, but due to version restrictions and other restrictions, only 32-bit systems can be installed, resulting in this problem.

Apply patch p8670579.
