How to assign a Port Number to an instance in DB2

-
1. Add an entry to the TCP/IP Services file:


db2_c_<inst_name> 50000/tcp # DB2 Instance connection port for instance DB2C1

The service name db2_c_<inst_name> can be any name you choose, but must be unique in the Services file

and must match the value you specify for the SVCENAME parameter in the DBM CFG file.

The port number you specify should be an integer greater than 1024.

The port numbers must be unique within the Services file.


2. On a Linux or UNIX system, the services file is located in the directory path of /etc/services. You must be update it. 

 

 On a Windows system, the Services file is located in the directory path of \windows\system32\drivers\etc\services.

 

3.On an AIX system, synchronize the /etc/services file and the inetd daemon by

executing the following commands:

# inetimp

# refresh -s inetd

 

$ db2 update dbm cfg using  SVCENAME 50000

 

 After the database manager is stopped and started again, view the database manager configuration file to ensure that these changes have taken effect.

How to fix DB2 Tablespace OFFLINE state issue?

Sometimes we face an error where one (or more) of our db2 tablespaces goes offline caused by loads, DB crashes, abnormal db2 services/or server shutdown, etc. So in this blogpost let us see how can we check which tablespace is in OFFLINE state and bring back tablespace’s state to ONLINE.   Finding TableSpace State To check which tablespace is OFFLINE, execute the below command: SYNTAX: db2 connect to <database_name> db2 list tablespaces |egrep -i "ID|Name|State" db2 list tablespaces show detail   If u see Tablespace state with 0x4000, then that tablespace is in Offline state There are 2 methods to resolve the tablespace from offline to online as below. Method1: We can execute below DB2 commands to take off tablespace's OFFLINE state.   db2 terminate db2 force application all db2 connect to <database_name>   Method 2:  Perform ALTER Tablespace command to bring the tablespace up while the rest of the database is still up...

How to determine fenced User-ID of a DB2 instance

-
When you create a DB2 instance in Unix, you have the option of specifying a fenced user-id different than instance owner. The purpose of fenced user id is to protect DB2 from untested or malicious code from the external stored procedures, user defined functions etc. When you try to run these external procedures, they run in a separate address space owned by the fenced user id.   You know about the fenced user id if you created a DB2 instance yourself on your Unix platform. But suppose, you are looking at a DB2 instance created by someone and you are wondering as which is the fenced user id, you can look at the user and group id of the file .fenced in ~/sqllib/ctrl directory and this will tell you as which is the fenced user id. For Eg:/home/db2inst1/sqllib/ctrl/.fencedID It will display the fenced user id for the instance db2inst1   Another method to find the fenced user id is   db2pd -fmp
