使用DBUA从9i到10G升级数据库.doc

使用DBUA从9i到10G升级数据库OS: HP-UX 11.23 # uname -aHP-UX RX3600-3 B.11.23 U ia64 1955595348 unlimited-user license ORACLE 9.2.0.6 ORACLE 10.2.0.1 注: 不会在这里贴图, 所以把图全删了, 改用文字描述. 1.使用和9i相同的用户来安装Oracle10G，安装时选择不同的ORACLE_HOME目录，并且取消建库选择项。 在安装Oracle10G的时，安装程序检查出HP-UX有不符合的条件： Checking for PHSS_33278; found Not found.Failed Checking for PHSS_33279; found Not found.Failed Checking for PHSS_33277; found Not found.Failed Checking for PHSS_33279; found Not found.Failed Checking for maxssiz_64bit=1073741824; found maxssiz_64bit=268435456.Failed Checking for maxswapchunks=16384; found no entry.Failed Checking for maxuprc=3687; found maxuprc=256.Failed Checking for msgmap=4098; found msgmap=514.Failed Checking for msgmni=4096; found msgmni=512.Failed Checking for msgseg=32767; found msgseg=8192.Failed Checking for msgtql=4096; found msgtql=1024.Failed Checking for semmap=4098; found no entry.Failed Checking for shmmni=512; found shmmni=400.Failed Checking for vps_ceiling=64; found vps_ceiling=16.Failed Check complete. The overall result of this check is: Failed Problem: The kernel parameters do not meet the minimum requirements (see above). Recommendation: Perform. operating system specific instructions to update the kernel parameters. 上面提示的补丁没理，只修改了要求的系统参数(不加参数则表示参数立刻生效)： kctune -h maxssiz_64bit=1073741824 kctune -h maxswapchunks=16384 kctune -h maxuprc=3687 kctune -h msgmap=4098 kctune -h msgmni=4096 kctune -h msgseg=32767 kctune -h msgtql=4096 kctune -h semmap=4098 kctune -h shmmni=512 kctune -h vps_ceiling=64 2.确认/etc/oratab文件里含有要升级的数据库的条目，在此文件的配置里，要使用9i的环境变量，dbua会自动更新该文件，如下： *:/oracle/oracle/product/9.2.0:N gxsi:/oracle/oracle/product/9.2.0:N dbua程序执行过程中即更新该文件： *:/oracle/oracle/product/9.2.0:N gxsi:/oracle/oracle/product/10.2.0:N 3.设置环境变量以准备执行dbua： #su – oracle 因为要使用10G的DBUA，所以要使ORACLE_HOME变量的为10G的目录： export ORACLE_BASE=/oracle/oracle export ORACLE_HOME=/oracle/oracle/product/10.2.0/ export PATH=$ORACLE_HOME/bin:$PATH export DISPLAY=10.154.249.5:1.0 可以使用xclock来测试。 4.执
