Different Environment Variable in OS and Solman

[former_member185274]

Hi dear experts,

I have a weird question here. I set the environment variable in the OS as blew:

smsp:smpadm 52> echo $PATH

/sybase/SMP/ASE-15_0/jobscheduler/bin:/sybase/SMP/ASE-15_0/bin:/sybase/SMP/ASE-15_0/install:/sybase/SMP/DBISQL/bin:/sybase/SMP/OCS-15_0/bin:/usr/sap/SMP/DVEBMGS00/exe/sapjvm_4/bin:/home/smpadm/bin:/usr/sap/SMP/hdbclient:/sapdb/programs/bin:/sapdb/clients/SMP/bin:/sapdb/clients/SMP/pgm:/sapdb/programs/pgm:/sapdb/programs:/sapdb/programs/lib:/root/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/games:/usr/lib/mit/bin:/usr/lib/mit/sbin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/usr/sap/SMP/SYS/exe/uc/linuxx86_64:/usr/sap/SMP/SYS/exe/run:/home/smpadm:.

But in solman, I run the same command in RSBDCOS0, get this：

echo $PATH

/usr/sap/SMP/DVEBMGS00/exe:/sybase/SMP/ASE-15_0/jobscheduler/bin:/sybase/SMP/ASE-15_0/bin:/sybase/SMP/ASE-15_0/install:/sybase/SMP/DBISQL/bin:/sybase/SMP/OCS-15_0/bin:/usr/sap/SMP/DVEBMGS00/exe/sapjvm_4/bin:/home/smpadm/bin:/usr/local/bin:/bin:/usr/bin:/u

It's same as what I found in program by debugging. And that's the reason why I failed to install MaxDB.

I have restarted solman, but the issue persisted. Can you give me any advices? Thank you.

Pany Pan

Hi Pany,

In addition to above kindly raise support ticket with OS support before performing any amendments in your system.

Hi Gaurav and Divyanshu,

The report RSADA_CHECK_SERVERS ran successfully just now. Some other guy suggest me to apply the note 823941, and it works. So it seems that the program sapstartsrv doesn't read the correct environment variable when starting solman.

@Divyanshu, We can change the work directory by clicking the above button "Change current directory" in RSBDCOS0, and the variable which stores the PATH is defined as 10000 characters long(I check it by debuging the program), so what we sow in RSBDCOS0 may be incorrect.

Thank you very much for your support!

Pany

Hi Pany,

Did you check the source code ?

Also, Did check by changing the PATH ?

Divyanshu

Hi Pany,

Thanks for sharing the solution.Kindly close the thread.

Hi Pany,

If possible kindly mention PATH variable value under .profile file and share the result of command echo $PATH .

Regards,

Gaurav

[former_member182657]

Hi Pany,

No need to change anything under it.Earlier you mentioned you performed or inserted some values under profile file.If possible try to share this file (.profile)

su - <sid>adm

ls -a .profile

For test append .profile file with PATH=$PATH:/usr/local/bin at the end of file.After that execute

export PATH

Hi Gaurav,

I maintain the environment variable in .cshrc, as below:

# @(#) $Id: //bas/720_REL/src/krn/tpls/ind/SAPSRC.CSH#1 $ SAP

# necessary to get hostname without domain (AIX, OS/390 and NOT sun)

switch (`uname`)

   case AIX*:

       alias hostname 'hostname -s'

   breaksw

   case OS/390*:

       setenv _BPXK_AUTOCVT ON

       setenv _TAG_REDIR_IN TXT

       set    _TAG_REDIR_IN=TXT

       setenv _TAG_REDIR_OUT TXT

       set    _TAG_REDIR_OUT=TXT

       setenv _TAG_REDIR_ERR TXT

       set    _TAG_REDIR_ERR=TXT

       alias hostname 'hostname -s'

   breaksw

endsw

# SAP environment

if ( -e $HOME/.sapenv_`hostname`.csh ) then

   source $HOME/.sapenv_`hostname`.csh

else if ( -e $HOME/.sapenv.csh ) then 

   source $HOME/.sapenv.csh

endif

   source $HOME/.apoenv_`hostname`.csh    

endif

if ( -e $HOME/.lcenv_`hostname`.csh ) then

   source $HOME/.lcenv_`hostname`.csh

else if ( -e $HOME/.lcenv.csh ) then 

   source $HOME/.lcenv.csh    

endif

# JAVA environment

   source $HOME/.j2eeenv_`hostname`.csh    

else if ( -e $HOME/.j2eeenv.csh ) then 

   source $HOME/.j2eeenv.csh    

endif                                     

# XI environment                         

if ( -e $HOME/.xienv_`hostname`.csh ) then

   source $HOME/.xienv_`hostname`.csh    

else if ( -e $HOME/.xienv.csh ) then 

   source $HOME/.xienv.csh    

endif                               

# RDBMS environment

   source $HOME/.dbenv_`hostname`.csh

else if ( -e $HOME/.dbenv.csh ) then 

   source $HOME/.dbenv.csh

endif

setenv TNS_ADMIN /usr/sap/SMP/SYS/profile/oracle

setenv NLS_LANG AMERICAN_AMERICA.UTF8

setenv PATH "/sapdb/programs/bin:/sapdb/clients/SMP/bin:/sapdb/clients/SMP/pgm:/sapdb/programs/pgm:/sapdb/programs:/sapdb/programs/lib:$PATH"

setenv LD_LIBRARY_PATH "/sapdb/clients/SMP/lib:/sapdb/programs/lib:$LD_LIBRARY_PATH"

And it works in OS side.

Hi Divyanshu/Pany,

I'm not satisfied with the above,as same i tested at my end and i got exact values for variable PATH at OS level with the mentioned report by Pany.

@Pany  kindly share files .bashrc  and bashrc (from /etc  directory)

Regards,

Gaurav

[divyanshu_srivastava3]

Hi Gaurav,

I have tested this on almost 7 different system and results were same.

Fixed characters in a line and rest truncated. Try to count the characters. I just cross checked.

Hi Pany,

I have found the reason.

Every line is limited to around 250 characters in RSBDCOS0 console.

When you execute PATH command, it tries to fill the current line but gets trunctaed after nearly 250 characters.

That is the reason you are getting that difference.

Regards,

Divyanshu

[divyanshu_srivastava3]

It's 255, just check by counting.

Regards,

Divyanshu

[former_member185274]

Hi Divyanshu,

I still think that the PATH environment variable is different in OS and sap system.

1. You can see, that the sequence of the result of "echo $PATH" in RSBDCOS0 is not accordance with what we can see in OS side.(/usr/sap/SMP/DVEBMGS00/exe:/sybase/SMP/ASE-15_0/jobscheduler/bin:/sybase/SMP/ASE-15_0/bin:/sybase/SMP/ASE-15_0/install:/sybase/SMP/DBISQL/bin:/sybase/SMP/OCS-15_0/bin:/usr/sap/SMP/DVEBMGS00/exe/sapjvm_4/bin:/home/smpadm/bin:/usr/local/bin:/bin:/usr/bin:/u

and  /sybase/SMP/ASE-15_0/jobscheduler/bin:/sybase/SMP/ASE-15_0/bin:/sybase/SMP/ASE-15_0/install:/sybase/SMP/DBISQL/bin:/sybase/SMP/OCS-15_0/bin:/usr/sap/SMP/DVEBMGS00/exe/sapjvm_4/bin:/home/smpadm/bin:/root/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/games:/usr/lib/mit/bin:/usr/lib/mit/sbin:/usr/lib/mit/bin:/usr/lib/mit/sbin:/usr/sap/SMP/SYS/exe/uc/linuxx86_64:/usr/sap/SMP/SYS/exe/run:/home/smpadm:.)

2. I debug the program RSADA_CHECK_SERVERS to check the root cause and find the environment variable PATH in table t_env is the same with the result in RSBDCOS0.

Please suggest, thank you,

Regards,

Pany

[divyanshu_srivastava3]

Hi Pany,

Thanks for this.

I was looking this from one view only, that was number of characters.

Let me check this again.

Divyanshu

[divyanshu_srivastava3]

Hi Pany,

One more thing that I found with the env of this report. By default, the current PATH(which you can see using PWD command) is /usr/sap/SMP/DVEBMGS00/exe. Even, If you will change the PATH (using cd command) it will remain same. So, here the current PATH is prefixed with the OS path for SIDADM.

Regards,

Divyanshu

[divyanshu_srivastava3]

Also, you will look at the source code, you will find both the reasons that I stated.

1. 255 characters is line length

2. PATH will remain the work directory even if you  try change it, because the code changes it to default, that is your work directory, which is your current PATH, hence prefixed in OS PATH.

Regards,

Divyanshu

[former_member182657]

Hi Pany,

What about the value under .sapenv_hostname.csh . If possible try to share the file.In addition kindly check SCN link

Regards,

Gaurav

[former_member182657]

Hi Pany,

Could you please share values under .bash_profile file (<sid>adm).

It should be like as PATH = $PATH:$HOME/bin

Regards,

Gaurav

[former_member185274]

Hi Gaurav,

There isn't a file named .bash_profile in home directory, but file .bashrc and .cshrc exist.

I maintained the environment variable in .cshrc and it worked at OS side, but in sap system it has no change(I have restarted the sap system.).

Regards,

Pany

[divyanshu_srivastava3]

Hi Pan,

What is your OS ?

Divyanshu

[divyanshu_srivastava3]

Did you match the contents with the (dot) .profile ?

[former_member185274]

Hi Divyanshu,

Thank you for your reply, my OS is SUSE 11, sap system is solman 7.1 SP11, but what do you mean match the contents with the .profile?

Regards,

Pany Pan

[divyanshu_srivastava3]

By referring dot(.), I meant hidden env profiles for sidadm and other users.

Which should be in their home directory respectively.

Regards,

Divyanshu

[former_member185274]

Yeah, I maintained the environment variable in .cshrc, .sapenv.csh in their home directory and in /etc/profile, but all failed.

Regards,

Pany
