今天安装了db2，忙了好一阵子，上网找资料等，终于装好了，下面就把我的步骤跟大家分享一下。
第一步:检查程序包及其版本
compat-libstdc -7.3-2.96.118.i386.rpm
在linux的安装盘上,找到后使用rpm -icompat-libstdc -7.3-2.96.118.i386.rpm安装即可
第二步:配置 Linux 内核参数
/etc/sysctl.conf文件，，添加内核参数
kernel.msgmni =1024
kernel.sem = 250 256000 32 1024
使更改激活：sysctl –p
第三步:安装
sh db2_install
按照提示做
第四步：创建用户
/usr/sbin/groupadd db2iadm1
/usr/sbin/groupadd db2fadm1
/usr/sbin/useradd –m -g db2iadm1 –d /home/db2inst1 db2inst1
/usr/sbin/useradd –m -g db2fadm1 –d /home/db2fenc1 db2fenc1
第五步：创建实例
/opt/IBM/db2/V8.1/instance/db2icrt –a server –udb2fenc1db2inst1
第六步：产品许可证
/opt/IBM/db2/V8.1/adm/db2licm-a/mnt/cdrom/db2/license/db2pe.lic
第七步：允许SMS的多页分配
/opt/IBM/db2/V8.1/cfg/db2ln
第八步：添加DB2端口
SU - root
vi /etc/services 加入下面一行
db2inst1 50000/tcp
第九步：DB2 配置
su – db2inst1
db2set DB2_EXTENDED_OPTIMIZATION=ON
db2set DB2_DISABLE_FLUSH_LOG=ON
db2set AUTOSTART=YES
db2set DB2_STRIPED_CONTAINERS=ON
db2set DB2_HASH_JOIN=Y
db2set DB2COMM=tcpip
db2set DB2_PARALLEL_IO=*
db2set DB2CODEPAGE=819
#Update dbm cfg
db2 update dbm cfg using SVCENAME db2inst1
db2 update dbm cfg using INDEXREC ACCESS
第十步：运行DB2
db2start
第十一步：创建库
db2 CREATE DATABASE test1 ALIAS test1 USING CODESETISO8859-1TERRITORY CN
以后就可以创建表和对表操作了，如 db2 select * from tbl

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps
