Error 

dasm: asm/opazcns0.asm line 147:DASM144E Begin-to-continue columns not blank

dasm: asm/opazcns0.asm line 147:DASM063E No ending apostrophe

dasm: asm/opazcns0.asm line 147:DASM435I Record 147 in asm/opbzcns0.asm

Solution -

This is applicable for assembler code and Aix platforms ( I tried in ZOS(OS390) and Aix platforms)

File named asm/opazcns0.asm  is having characters of more than 71 in a single line which is not allowed. 

In other words there cannot be a character in column 72 for line number 147

7acf13c1390e451f721b3ae6779e8fca8f737b12

it will list the latest common commit between both the branches. i.e after this particular commit branch bug-1234 is branched out

Not able to login Jenkins ? Locked yourself by messing security ? How to disable security in Jenkins

Rarely we end up locking ourself in jenkins so that we couln't login Jenkins.


For example -

If you enable security before creating an account, you end up being access denied with out any login account in hand.
























Jenkins throws error like

javax.servlet.ServletException: hudson.security.AccessDeniedException2: anonymous is missing the Overall/Administer permission

This can be solved by editing the config.xml  and disabling the security by changing

<useSecurity>true</useSecurity>

into 

<useSecurity>false</useSecurity>

You can refer this url from Jenkins - https://wiki.jenkins-ci.org/display/JENKINS/Disable+security

How to overwrite symbolic links in unix

You can overwrite symbolic links by using -f to the default command

Example
mohan@mysys /cygdrive/c/
$ ln -s /tmp/test.sh tumba
mohan@mysys /cygdrive/c/
$ ls -l
total 80
lrwxrwxrwx  1 mohan        Domain Users    5 Oct  9 14:59 tumba -> /tmp/test.sh
mohan@mysys /cygdrive/c/
$ ln -s /tmp/build_env.log  tumba
ln: failed to create symbolic link `tumba': File exists
mohan@mysys /cygdrive/c/

 Now we can overwrite the existing symbolic link by using -f







$ ln -s -f /tmp/build_env.log  tumba
mohan@mysys /cygdrive/c/
$ ls -l
total 80
lrwxrwxrwx  1 mohan        Domain Users    5 Oct  9 14:59 tumba -> /tmp/build_env.log
