DBI1131E The user ID ERROR: is invalid.
作者：互联网
今天在生产机上做fixpack的升级。
一开始觉得问题应该不大，当然备份也已经做了，没曾想./installFixPack 命令发出后，漫长等待了执行到step 50，卡了很久（我这是DB2 V11.1)，
然后窗口超时。。。。退出了。
无奈重新进入，想着刚才的./installFixPack也没执行完，就再执行一次，可这报错就来了！
root:/db2data/universal # ./installFixPack -b /opt/ibm/db2/V11.1
DBI1131E The user ID ERROR: is invalid.
Explanation:
An attempt to access the given user ID failed. One of the following
situations has occurred:
* This user ID does not exist on the system.
* The home directory of this user does not exist or is not set up
properly.
* One of the user attributes needed by the database manager is unset.
* The UID of this user is 0
User response:
Make sure a valid user ID with valid home directory, shell, primary
group and secondary group has been used. Create a new user if necessary.

The user ID ERROR: is invalid. 这是什么鬼！这究竟啥意思。。。
然后就各种检查，差点就打算要重新卸载DB2再安装了，反正有备份，俺们不怕！
突然在检查的过程中，输了db2ilist，一堆乱七八糟的东西就出来了
db2inst1@myserver:~> db2ilist

Contact IBM Support if the problem persists.
各位请注意这句话，我一开始开到一堆东西晕得，差点漏掉，导致我在尝试做db2idrop也是报错，回头来仔细看才发现有这么一句话！ 划重点。
然后就照着执行了！
root:/opt/ibm/db2/V11.1/instance # /opt/ibm/db2/V11.1/install/db2chgpath
The output will be saved in /db2data/tmp/db2chgpath.log.18982
Starting the update of runtime path ...

Changing the embedded runtime path for DB2 deliverables installed
under /opt/ibm/db2/V11.1 from /opt/ibm/db2/V11.1/ to /opt/ibm/db2/V11.1/
---> Please wait
这一步等了大概有20分钟。。。。
Output was saved in the log file /db2data/tmp/db2chgpath.log.18982
Sat Oct 26 23:10:23 AEDT 2019
Program db2chgpath completed successfully.
貌似有什么成功了？
回过头进入实例，执行db2ilist， 哎！ 这次那对乱七八糟的东西不见了。
root:/opt/ibm/db2/V11.1/instance # su - db2inst1
db2inst1@myserver:~> db2ilist
db2inst1
db2inst1@myserver:~> logout
那我们再执行一次安装。鉴于前面安装了一半，这里需要加上-f level强制其在同版本中覆盖安装。
(这里有个要注意的地方，如果你没有export tmp的路径，可能你当前的tmp目录会有权限不够的情况，建议先提前创建一个tmp，并export到指定的临时目录）
myserver:/opt/ibm/db2/V11.1/instance # cd /db2data/universal/
myserver:/db2data/universal # export DB2TMPDIR=/db2data/tmp
myserver:/db2data/universal # ./installFixPack -f level -b /opt/ibm/db2/V11.1
Do you want to choose a different installation directory for the fix pack? [yes/no]
------------------------------------------------------------------------------------
no
DBI1017I installFixPack is updating the database products installed in
location /opt/ibm/db2/V11.1.
DB2 installation is being initialized.
然后然后然后就成功了！！！
