How to run several dssh scripts in one batch

[hailun]

Hi,
I would like to realize one function retrieving the hash_num for one job using shellscript,the server is of AIX

What I do now in the script file is
'hellp' is project name and 'Test' is the job name

dssh<<eof
logto hellp
select JOBNO FROM DS_JOBS WHERE NAME ='Test'
quit
eof

But it will take long time to run and return no record,
BTW I type the command as following
dssh<<eof
>logto hellp
>SELECT JOBNO FROM DS_JOBS WHERE NAME = 'Test'
>QUIT
It is OK

Can any one of you post kindly advice here...

try

Code: Select all

dssh<<eof
pterm case noinvert
SELECT JOBNO FROM DS_JOBS WHERE NAME = 'Test';
QUIT;
eof

Note the switching off of case inversion and the semicolon on the SQL

... but lose the semi-colon after QUIT

dssh<<eof
pterm case noinvert
SELECT JOBNO FROM DS_JOBS WHERE NAME = 'Test';
QUIT
eof

Hi ArndW&ray,
Thank you for your kindly inputs,and the script as above works,I have another question here,is there any way so as I have transfer the output of the Select query to one Unix variable or plain file. I have tried adding redirection symbol '>'
following <<eof and eof and SELECT JOBNO FROM DS_JOBS WHERE NAME = 'Test'; but none of them works,,,

How about just using SH scripting
(from UNIX)
cd {project directory}
dssh "SELECT JOBNO FROM DS_JOBS WHERE NAME = 'Test';" > textfile.txt

Hi ArndW,
Thank you for input, the method mentioned does work,bu it is said it is not a good habit to run dssh/uvsh under other paths than $DSHOME,
And I have achieved this by function calling,detailed as following:
。。。。。。。。。。。。。。。。
run_dssh()
{ a=$1
b=$2
cd $a
dssh<<eof
LOGTO $2
SELECT * FROM DS_JOBS;
QUIT
eof
}

run_dssh $DSHOME $pro_name > ./filename
。。。。。。。。。。。。。。。。
Hence the record returned by the SELECT query will be returned to file filename under present path

However,I have another question now,is there any way to run "dssh SELECT * FROM RT_LOG$HASH_NUM" under path $DSHOME,however the RT_LOG$HASH_NUM" is under some project path

How about just using SH scripting
(from UNIX)
cd {project directory}
dssh "SELECT JOBNO FROM DS_JOBS WHERE NAME = 'Test';" > textfile.txt ...

I don't know why you think it is bad to call up dssh outside of the $DSHOME directory - I think it is better and safer, as the "UV" account, if inadvertantly modified, can affect all projects on the system.

The question regardnig accessing the RT_LOGnnn file(s) in a different project from within the UV project is answered with a definitive "NO", as you do not want to add remote file pointers to the main UV account.

Yeah,although I could not read the fulltext of comments posted by you,I can know you are supporting running dssh under project path other thant $DSHOME

And in fact,few persons I know care under which folder the dssh is executed.

I believe we can resolve my last question someday in future...

As you have support resolving two queries factly,I would like to mark this topic resolved here..

Thank you both....

dssh can be run satisfactorily in any project directory, as well as in $DSHOME - each project directory is an "account" for dssh. But it is vital that the dsenv script has been executed first - that's why (I believe) advice is usually given to execute in $DSHOME, the location of the dsenv script.
