【翻译自mos文章】使用dbua升级到70%左右时，os hang

来源于：Database Upgrade Crashes Server at around 70 Percent (文档 ID 551886.1)

适用于：
 Oracle Server - Enterprise Edition - Version: 10.2.0.2
Linux x86

症状：

-- Problem Statement:
1. Oracle 10.2. is installed on Red Hat Enterprise Linux
2. The Database Upgrade Assistant (DBUA) is used to upgrade a 10.1 database to 10.2.
3. The upgrade progresses to ~70% then the server hangs, requiring power-cycle to reboot.
4. The hang occurs in initimnc.sql ...
 ....
REM create reset procedure 
create or replace procedure java_reset(value IN NUMBER) 
2 as LANGUAGE JAVA 
3 name 'java.lang.System.exit(int)'; 
4 / 
...

原因：

Kernel version < 2.6.9-55.0.2.EL 

This can be caused by a Red Hat kernel bug that appears to have been corrected in:
kernel-2.6.9-55.0.2.EL 

Reference:
http://rhn.redhat.com/errata/RHSA-2006-0132.html 
Bugzilla 173981 - kernel bug at mm/prio_tree.c 

解决方案：

-- To implement the solution, please execute the following steps:

1. Obtain and install the RPM for kernel-2.6.9-55.0.2.EL (or newer). ---额外注意：kernel-2.6.9-55.0.2.EL是rhe4.5，也就是说小于4.5会有此bug

2. Re-attempt the failed upgrade process by using the DBUA or manual (CATUPGRD.SQL).
