How to resolve error SQL30082N reason code 42 when Connect to a database through client

Receiving error SQL30082N reason code 42 when Connect to a database via client

Once I've received a complaint from our internal team, that they are unable to connect to the database from the DB2 Client terminal. 

Operating System: Windows

DB2 Client Version: V9.7 AESE

DB2 Server Version: V9.7 AESE

Error:

C:\Users\test>db2 connect to sampledb user test1 using test1

SQL30082N  Security processing failed with reason "42" ("ROOT CAPABILITY REQUIRED").  SQLSTATE=08001

Cause:

Any changes on DB2 files such as db2ckpwd that require root permissions can result in this error message.

Resolving the problem:

Often a simple update ran against the instance using the db2iupdt command will correct permissions on DB2 files.

As root run the command "db2iupdt <instance name>".

(OR)

1) cd to sqllib/security

2) run: ls -l 

3) Check the permission's on the db2chpw and db2ckpw they should be:

       -r-s--x--x 1 root inst1 51195 Dec 1 15:33 db2chpw 

       -r-s--x--x 1 root inst1 3534773 Dec 1 15:33 db2ckpw 

If you need to change the permission's of those files run the following commands (this needs to be done as root, since the files are owned by root): 

        chmod 4511 db2chpw 

        chmod 4511 db2ckpw 

Stop and restart the instance.
