DB2从10.5.0.8到10.5.0.10打补丁

1. 下载DB2

https://www-01.ibm.com/support/docview.wss?uid=swg27007053 

选择DB2 10.5  FixPack 10

2.备份当前的dbm cfg和db cfg，db2support, db2look，packages, db backup, 强烈建议。

(1). dbm cfg:   db2 get dbm cfg > db2inst1.dbm.cfg

(2). db cfg:  db2 get db cfg for sample > sample.db.cfg

(3). db2support : db2support . -d sample -c -s

(4). db2look:     db2look -d sample -a -l -e -x -o sample.ddl

(5). packages:  db2 list packages for all show detail > sample_packages.txt

(6). db2 backup db sample

(7).诊断日志截断/归档:  db2diag -A

 

3.停止实例，服务，应用。准备升级。

(1) su - db2inst1

(2). db2 force application all

(3). db2 terminate

(4). db2stop

(5). db2licd -end

 如果启用了DAS需要切换到das用户，然后关闭das管理服务器

(6). su - dasusr1

(7). db2admin stop
 

4. 将下载的补丁包(其实就是安装包)放到主机上并解包/解压, 然后进入到其server_t路径:

/db2_softs_v10.5.0.10/server_t

 

5. 安装补丁包:

./installFixPack -b  -f update -b /opt/ibm/db2/V10.5

具体执行如下:

[root@localhost server_t]# ./installFixPack  -f update -b /opt/ibm/db2/V10.5 
Requirement not matched for DB2 database "Server" . Version: "10.5.0.10". 

Summary of prerequisites that are not met on the current system: 

   DBT3514W  The db2prereqcheck utility failed to find the following 32-bit library file: "/lib/libpam.so*". 

DBT3514W  The db2prereqcheck utility failed to find the following 32-bit library file: "libstdc++.so.6". 

Do you want to choose a different installation directory for the fix pack? [yes/no] 

------------------------------------------------------------------------------------
yes

Enter the full path for the fix pack installation directory:

------------------------------------------------------------
/opt/ibm/db2/V10.5_FP10

DBI1017I  installFixPack is updating the DB2 product(s) installed in
      location /opt/ibm/db2/V10.5.

DB2 installation is being initialized.

Total estimated time for all tasks to be performed: 1732 second(s) 

Task #1 start
Description: Preparing the system 
Estimated time 120 second(s)

........

说明:

(1).  -b 后面的路径/opt/ibm/db2/V10.5是需要升级的原低版本DB2的安装路径，后面安装的时候会询问要不要改一个路径，填yes，输入一个高版本的新的安装路径/opt/ibm/db2/V10.5_FP10 。   

也可以不加-b  /opt/ibm/db2/V10.5选项，在后面交互模式输入。

(2).可以加上-f update选项， 如果不加这个选项，安装就会由于DBT3514W的报错中止，这个报错的意思是缺少32bit的库文件（DBT3514W），由于我安装的是64bit的DB2，如果没有32bit的应用可以忽略这个报错。 加上-f update选项之后虽然也会有警告，但是可以安装成功。

 

6. 安装之后，检查:

[root@localhost server_t]# db2ls

Install Path                       Level   Fix Pack   Special Install Number   Install Date                  Installer UID

[db2inst1@localhost V10.5_FP10]$ db2level
DB21085I  This instance or install (instance name, where applicable: 
"db2inst1") uses "64" bits and DB2 code release "SQL10058" with level 
identifier "0609010E".
Informational tokens are "DB2 v10.5.0.8", "s160901", "IP23993", and Fix Pack

Product is installed at "/opt/ibm/db2/V10.5".

因为只是安装了补丁安装包软件，而还没有升级实例，所以db2level显示还是老版本的安装路径。下面还需要升级实例:

 

7. 升级实例:

进入到新安装的高版本DB2安装路径下的instance下, 给定要升级的实例db2inst1为入参:

cd  /opt/ibm/db2/V10.5_FP10/instance
升级实例:       ./db2iupdt db2inst1

如下:

[root@localhost instance]# pwd
/opt/ibm/db2/V10.5_FP10/instance

[root@localhost instance]# ./db2iupdt db2inst1
DBI1446I  The db2iupdt command is running.

DB2 installation is being initialized.

 Total number of tasks to be performed: 4 
Total estimated time for all tasks to be performed: 309 second(s) 

Task #1 start
Description: Setting default global profile registry variables 
Estimated time 1 second(s) 
Task #1 end 

Task #2 start

Task #4 start

Task #4 end 

The execution completed successfully.

For more information see the DB2 installation log at "/tmp/db2iupdt.log.44087".
DBI1070I  Program db2iupdt completed successfully.

 

8. 启动实例，检查发现实例升级成功。

[db2inst1@localhost V10.5_FP10]$ db2start
01/16/2020 00:55:17     0   0   SQL1063N  DB2START processing was successful.

[db2inst1@localhost V10.5_FP10]$ db2 activate db sample
DB20000I  The ACTIVATE DATABASE command completed successfully.

[db2inst1@localhost V10.5_FP10]$ db2 connect to sample

   Database Connection Information

 Database server        = DB2/LINUXX8664 10.5.10
 SQL authorization ID   = DB2INST1
 Local database alias   = SAMPLE

 

需要注意的几个点:

1. 升级之前一定要停掉实例

2. 先安装补丁包./installFixPack ， 再升级实例./db2iupdt 

3. 安装补丁包./installFixPack的时候-b后面指定的路径为原先老版本数据库的路径(也可在后面的交互模式下指定)，然后再指定新版本路径。
