I'm working and discovering the world of Zabbix. In particular I am trying to monitor an Oracle database with the Zabbix server through an external script. Given that other external scripts work, however, I created one with sqlplus, but on Zabbix I get "command not found". Can you tell me why?
The code is:
check.pl
#!/usr/bin/perl
use strict;
use warnings;
my $out=`echo "select * from v$version;" | sqlplus user/password#ip_database:port`;
print $out;
The code is very simple.
I created an item as always, passed as type "external check" and a key I entered my script. Can anyone solve my problem? Also if I was not clear, just ask for more information rather than "insult" on the forum: Thanks to everyone in advance
I RESOLVED IT WITH:
echo "/usr/lib/oracle/11.2/client64/lib" > /etc/ld.so.conf.d/oracle.conf
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/oracle/11.2/client64/lib" >> /etc/profile
THANKS TO ALL!!!!
Apparently, your zabbix server does not have the necessary environment to find sqlplus. You could simply use the full path to sqlplus in your script (but that alone might not be enough) or create a wrapper script that sets all the necessary environment variables for your script.
From TFM:
The command will be executed as the user Zabbix server runs as, so any
access permissions or environment variables should be handled in a
wrapper script, if necessary, and permissions on the command should
allow that user to execute it.
You also have to configure the sqlplus libraries required to run sqlplus. The script which you use to start the zabbix server you can configure below oracle things in the startup script so that zabbix can find all necessary libraries to run.
export ORACLE_HOME={path to Oracle Client}
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${ORACLE_HOME}/lib
If still there are issues related to .so files then there must be some issues in your SQL client installation.

I wish to use a sqlplus command with password hidden from view such that it doesn't show up on ps -ef command.
I know there are a lot of solutions provided all over internet blogs but most of them seem to require admin privileges and I have restricted access on this server. And rest of them just don't seem to work me.
The command that I am currently using is as below:
sqlplus -s SOME_USERNAME/SOME_PASSWORD#somedns.intra.com:1500/SOMESID #some.sql
Legend:
SOME_USERNAME: schema/user
SOME_PASSWORD: password
SOMESID: SID for this DB.
#some.sql: An sql file containing insert statements.
Any pointers are much appreciated.
Update: Forgot to mention that this sqlplus command will be used inside a shell script.
How do I input the password from within a shell script in this case?
You can use a heredoc:
sqlplus -s /nolog <<!EOF
connect SOME_USERNAME/SOME_PASSWORD#somedns.intra.com:1500/SOMESID
#some.sql
!EOF
The connect and #some.sql are treated as an input stream to SQL*Plus, as if you'd typed them in an interactive session, and are not part of the initial call to the executable - so the connection details don't appear in ps output.
You can also use variables if you want to, incidentally, as the variable expansion happens in the shell before it passes the stream to the executable - so even though SQL*Plus wouldn't understand say $PASSWD, referring to that in the heredoc works and the actual variable value is passed.
Use sqlplus -s SOME_USERNAME#\"somedns.intra.com:1500/SOMESID\" #some.sql and enter your password on the command line.
Or use external authentication and don't use a password at all
Finally, SOMESID is not a SID, it's a Service Name. The Easy Connect syntax you use only works with service names. SIDs are very very old-school.
I have a script lying into a Unix server which looks like this:
mainScript.sh
#some stuff here
emailScript.sh $PARAM_1 $PARAM_2
#some other stuff here
As you can see, mainScript.sh is calling another script called emailScript.sh.
The emailScript.sh is supposed to perform a query via sqlplus, then parse the results and return them via email if any.
The interesting part of the code in emailScript.sh is this:
DB_SERVER=$1
USERNAME=$2
PASSWORD=$3
EVENT_DATE=$4
LIST_AUTHORIZED_USERS=$5
ENVID=$6
INTERESTED_PARTY=$7
RAW_LIST=$(echo "select distinct M_OS_USER from MX_USER_CONNECTION_DBF where M_EVENT_DATE >= to_date('$EVENT_DATE','DD-MM-YYYY') and M_OS_USER is not null and M_OS_USER not in $LIST_AUTHORIZED_USERS;" | sqlplus -s $USERNAME/$PASSWORD#$DB_SERVER)
As you can see, all I do is just creating the variable RAW_LIST executing a query with sqlplus.
The problem is the following:
If I call the script mainScript.sh via command line (PuTTy / KiTTy), the sqlplus command works fine and returns something.
If I call the script mainScript.sh via an external job (a ssh connection opened on the server via a Jenkins job), the sqlplus returns nothing and takes 0 seconds, meaning it doesn't even try to execute itself.
In order to debug, I've printed all the variables, the query itself in order to check if something wasn't properly set: everything is correctly set.
It really seems that the command sqlplus is not recognized, or something like this.
Would you please have any idea on how I can debug this? Where should I look the issue?
You need to consider few things here. While you are running the script, from which directory location you are executing the script? And while you are executing the script from your external application from which directory location it is executing the script. Better use full path to the script like /path/to/the/script/script.sh or use cd /path/to/the/script/ command to go to the script directory first and execute the script. Also check execute permission for your application. You as an user might have permission to execute the script or sql command but your application does not have that permission. Check the user id for your application and add that into the proper group.
We are using CA Workload Control Center (Autosys) to run a windows batch file which calls another batch file which calls SQLPlus with the following:
sqlplus username/password %1 %2 %3
Since this is all being done remotely I cannot see what is actually happening on the server.
I am wondering if the sqlplus file exists but has invalid syntax (like referring to non-existent table) will the sqlplus prompt exit and return back to the batch file?
The reason I ask is because I am looking at the log file from Autosys and it shows that SQLPlus call was made, it prints out ERROR AT LINE 2: Invalid Table, but then it does not show any other activity with the batch script after that where there are multiple echoes and file copies etc. It seems as though it is not exiting SQLPlus perhaps?
Is there a parm I need to pass to SQLPlus to tell it to exit SQLPlus and return back to the calling script after running a SQL script if it fails?
Edit: We are using "WHENEVER SQL ERROR" inside of our SQL files as well and the log file does show this:
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,
Data Mining and Real Application Testing options
But I am still expecting that it should continue with the rest of the Batch script but its not, above is the last that Autosys shows in the log
See SQLPlus instruction WHENEVER SQLERROR, it describes in Oracle docs:
http://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12052.htm
Found the solution SO Post:
You can do sqlplus -l test/Test#mydatabase #script.sql; the -l flag means it will only try to connect once, and if it fails for any reason will exit instead of prompting. Look at the output of sqlplus -?, or see the documentation.
My host upgraded my version of FreeBSD and now one of my scripts is broken. The script simply uploads a data feed to google for their merchant service.
The script (that was working prior to the upgrade):
ftp ftp://myusername:mypassword#uploads.google.com/<<END_SCRIPT
ascii
put /usr/www/users/myname/feeds/mymerchantfile.txt mymerchantfile.txt
exit
END_SCRIPT
Now the script says "unknown host". The same script works on OSX.
I've tried removing the "ftp://". - No effect
I can log in from the command line if I enter the username and password manually.
I've search around for other solutions and have also tried the following:
HOST='uploads.google.com'
USER='myusername'
PASSWD='mypassword'
ftp -dni <<END_SCRIPT
open $HOST
quote USER $USER
quote PASS $PASS
ascii
put /usr/www/users/myname/feeds/mymerchantfile.txt mymerchantfile.txt
END_SCRIPT
And
HOST='uploads.google.com'
USER='myusername'
PASSWD='mypassword'
ftp -dni <<END_SCRIPT
open $HOST
user $USER $PASS
ascii
put /usr/www/users/myname/feeds/mymerchantfile.txt mymerchantfile.txt
END_SCRIPT
Nothing I can find online seems to be doing the trick. Does anyone have any other ideas? I don't want to use a .netrc file since it is executed by cron under a different user.
ftp(1) shows that there is a simple -u command line switch to upload a file; and since ascii is the default (shudder), maybe you can replace your whole script with one command line:
ftp -u ftp://username:password#uploads.google.com/mymerchantfile.txt\
/usr/www/users/myname/feeds/mymerchantfile.txt
(Long line wrapped with \\n, feel free to remove the backslash and place it all on one line.)
ftp $HOSTNAME <<EOFEOF
$USER
$PASS
ascii
put $LOCALFILE $REMOTETEMPFILE
rename $REMOTETEMPFILE $REMOTEFINALFILE
EOFEOF
Please note that the above code can be easily broken by, for example, using spaces in the variables in question. Also, this method gives you virtually no way to detect and handle failure reliably.
Look into the expect tool if you haven't already. You may find that it solves problems you didn't know you had.
Some ideas:
just a thought since this is executed in a subshell which should inherit correctly from parent, does an env show any difference when executed from within the script than from the shell?
Do you use a correct "shebang"?
Any proxy that requires authentication?
Can you ping the host?
In BSD, you can create a NETRC script that ftp can use for logging on. You can even specify the NETRC file in your ftp command too using the -N parameter. Otherwise, the default NETRC is used (which is $HOME/.netrc).
Can you check if there's a difference in the environment between your shell-login, and the cron-job? From your login, run env, and look out for ftp_proxy and http_proxy.
Next, include a line in the cron-job that will dump the environment, e.g. env >/tmp/your.env.
Maybe there's some difference...Also, did you double-check your correct usage of the -n switch?
Please tell me what is the use of TNS_ADMIN parameter in Oracle? I am working on Unix using oracle database.
Is this parameter is required to locate the sqlplus. I am executing a script in which a update query is executed on Oracle Database.
The script fails with 127 error code when executed with crontab.
The script contents I suspect (eval) failing are
----------
cmd='sqlplus ${ORALOGIN} < SQLS
----------
eval $cmd
TNS_ADMIN tells sqlplus where to find the tnsnames.ora file.
If you are running sqlplus from a crontab then the normal reason for having difficulty are:
Incorrect path
Not having the correctly set ORACLE_SID or other Oracle connection information
A startup/login script that is getting executed when you login to the system that is interfering with your cron execution
Some script that you run from the command line when you login that sets up your Oracle environment that is not getting executed in your crontab.
Check these things and other environment related items. It always takes me a number of passes to get crontab and Oracle to work happily together.
