win平台登录sqlplus报ora-01031错误解决

发表于 2011 年 11 月 6 日 由 惜分飞

今天一朋友告诉我，他的win平台的oracle不能在本地使用sqlplus / as sysdba登录数据库，提示ora-01031的错误，他说是administrator用户，应该不会出现权限不足的情况。我的登录上去一看，果真是这样的情况：

01031, 00000, "insufficient privileges"
// *Cause: An attempt was made to change the current username or password
//         without the appropriate privilege. This error also occurs if
//         attempting to install a database without the necessary operating
//         system privileges.
//         When Trusted Oracle is configure in DBMS MAC, this error may occur
//         if the user was granted the necessary privilege at a higher label
//         than the current login.
// *Action: Ask the database administrator to perform the operation or grant
//          the required privileges.
//          For Trusted Oracle users getting this error although granted the
//          the appropriate privilege at a higher label, ask the database
//          administrator to regrant the privilege at the appropriate label.
根据这个错误提示，我的第一反应就是当前的用户不属于ora_dba用户组，通过计算机管理–>本地用户和组–>administrator用户属性–>隶属于中只有一个administrators，果然没有ora_dba组

接下来的事情，就是添加ora_dba组到administrator用户中
点击刚刚隶属于下面的添加–>高级–>立即查找–选择ora_dba–点击确定–>再点击选择组中的确定–>点击用户属性的确定


添加把ora_dba添加到administrator用户所属组中，再尝试登录

ok，登录成功了，看来在win系统中，要想使用sqlplus / as sysdba 登录数据库，必须要隶属于ora_dba组，就算administrators组也不能越俎代庖。

ORA-00845: MEMORY_TARGET not supported on this system

发表于 2011 年 11 月 5 日 由 惜分飞

在Oracle 11g中如果采用AMM内存管理，那么当MEMORY_TARGET的值大于/dev/shm的时候，就会报ORA-00845: MEMORY_TARGET not supported on this system错误，解决办法增加/dev/shm大小，在redhat系列系统中，/dev/shm的默认值是系统总内存的一半

1、错误重现

2、修改/dev/shm大小

[root@xifenfei ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_xifenfei-lv_root
                       17G   13G  3.9G  77% /

3、启动数据库验证

[oracle@xifenfei admin]$ sqlplus / as sysdba

sys@XFF>show parameter memory;
 
NAME                                 TYPE        VALUE
———————————— ———– ——————————
hi_shared_memory_address             integer     0
memory_max_target                    big integer 800M
memory_target                        big integer 800M
shared_memory_address                integer     0

4、官方解释
Starting with Oracle Database 11g, the Automatic Memory Management feature requires more shared memory (/dev/shm)and file descriptors. The size of the shared memory should be at least the greater of MEMORY_MAX_TARGET and MEMORY_TARGET for each Oracle instance on the computer. If MEMORY_MAX_TARGET or MEMORY_TARGET is set to a non zero value, and an incorrect size is assigned to the shared memory, it will result in an ORA-00845 error at startup.

5、解决问题建议
5.1. If you are installing Oracle 11g on a Linux system, note that Memory Size (SGA and PGA), which sets the initialization parameter MEMORY_TARGET or MEMORY_MAX_TARGET, cannot be greater than the shared memory filesystem (/dev/shm) on your operating system. To resolve the current error, increase the /dev/shm file size.

5.2. If configuring AMM is not possible due to lack of space on /dev/shm mount point, you can configure ASMM instead of AMM, i.e. set SGA_TARGET, SGA_MAX_SIZE and PGA_AGGREGATE_TARGET instead of MEMORY_TARGET.

RedHat 6.1安装Oracle 11.2.0.3

发表于 2011 年 11 月 4 日 由 惜分飞

一、操作系统版本
[root@xifenfei stage]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.1 (Santiago)
[root@xifenfei stage]# uname -a
Linux xifenfei 2.6.32-131.0.15.el6.i686 #1 SMP Tue May 10 15:42:28 EDT 2011 i686 i686 i386 GNU/Linux

二、安装数据库版本（安装后之后贴出来的）
[oracle@xifenfei database]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Sat Nov 5 05:50:34 2011

三、系统配置
1、检查相应的rpm包的情况(等于或者高于下面版本）
rpm –qa | grep pagename(grep是搜索)
binutils-2.17.50.0.6
compat-libstdc++-33-3.2.3
compat-libstdc++-33-3.2.3 (32 bit)
elfutils-libelf-0.125

glibc-2.5-24
glibc-2.5-24 (32 bit)
glibc-common-2.5
glibc-devel-2.5
glibc-devel-2.5 (32 bit)
glibc-headers-2.5
ksh-20060214
libaio-0.3.106
libaio-0.3.106 (32 bit)
libaio-devel-0.3.106
libaio-devel-0.3.106 (32 bit)
libgcc-4.1.2
libgcc-4.1.2 (32 bit)
libstdc++-4.1.2
libstdc++-4.1.2 (32 bit)
libstdc++-devel 4.1.2
make-3.81
numactl-devel-0.9.8.x86_64
sysstat-7.0.2
unixODBC-2.2.11
unixODBC-2.2.11 (32 bit)
unixODBC-devel-2.2.11
unixODBC-devel-2.2.11 (32 bit)
pdksh-5.2.14-1 –这个包需要下载，安装前需要卸载掉ksh-20100621-6.el6包
rpm –e rpm -e ksh-20100621-6.el6

安装缺少的rpm包
rpm –ivh pagename(根据提示，如果缺少依赖包，也需要加上去)

2、添加组和用户
/usr/sbin/groupadd oinstall（添加oinstall组）
/usr/sbin/groupadd -g 502 dba（添加dba组）
/usr/sbin/useradd -u 502 -g oinstall -G dba oracle（添加用户oracle，主组oinstall，辅助组dba）
passwd oracle（修改oracle用户密码）

3、创建文件夹并修改组和用户所属关系和相关权限
mkdir -p /opt/oracle(创建文件u01/oracle)
chown -R oracle:oinstall /opt/oracle(使得/opt/oracle文件夹输入oracle用户和oinstall组)
chmod -R 775 /opt/oracle(修改u01文件夹访问权限)—可选（最好执行下）

4、添加/etc/hosts中dns解析信息
192.168.1.60                xifenfei

5、在/etc/security/limits.conf中添加用户限制信息
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle hard stack 10240

6、修改或者添加/etc/sysctl.conf中信息
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 1048576
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
net.ipv4.tcp_wmem = 262144 262144 262144
net.ipv4.tcp_rmem = 4194304 4194304 4194304

注意注释掉
# Disable netfilter on bridges.
#net.bridge.bridge-nf-call-ip6tables = 0
#net.bridge.bridge-nf-call-iptables = 0
#net.bridge.bridge-nf-call-arptables = 0
—/sbin/sysctl –p（重新加载这些参数，不用重启系统）

7、编辑vi /etc/profile
if [ $USER = "oracle" ]; then
   if [ $SHELL = "/bin/ksh" ];    then
     ulimit -p 16384
     ulimit -n 65536
   else
     ulimit -u 16384 -n 65536
   fi
fi
–注意空格，在用户切换时使用su – username，这样才会加载后面的环境变量的配置信息（不要使用su username切换）

8、配置环境变量
在oracle用户下的.bash_profile文件中添加下面信息
ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/oracle
ORACLE_SID=xff
PATH=$ORACLE_HOME/bin:$PATH
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH NLS_LANG

四、安装过程
1、执行 runInstaller –注意路径，选择只安装数据库软件
2、执行 netca 创建监听
3、执行 dbca 创建数据库
