[hobbit] dbcheck for RAC connections refused

31 Jul 2009

      This is really strange.
Regarding the RAC test it cannot be done without the tnsnames.ora configuration.
What's the problem regarding the tnsnames.ora? does it exists?
The timeout problem seems also strange because it's like your client could not reach the database.
You should try to connect to the oracle client (sqlplus).
You can also try with this perl script
#/usr/bin/perl
use DBI;
$ENV{'ORACLE_HOME'}="/usr/local/oracle/10.2.0/client/";
$dbhost="hostname";
$port=1521;
$sid="SID";
$user="user";
$pw="password";
$data_source="DBI:Oracle:host=$dbhost;port=$port;sid=$sid";
$dbh = DBI->connect($data_source,$user,$pw ,{ RaiseError => 1, PrintError =>1});
$dbh->disconnect;
exit 0;
Let me know if there's any problem...

In tnsnames.ora (under ORACLE_HOME/network/admin) I've those configuration:
This is a good point, i can't use the tnsnames.ora, because my
oracle-software is placed in the global filesystem AFS ...
So, could this be a problem, if i have to got all informations only from dbcheck.ini ?

You can also try to connect with a telnet to the hostname and listener port
Yep, telnet to port 1521 is working .. to  lcg3d-a-v-1/4

In tnsnames.ora (under ORACLE_HOME/network/admin) I've those configuration:
CL10G =
(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = ITROMDB22)(PORT = 1521))
(LOAD_BALANCE = no)

(SERVICE_NAME = cl10g)

(CONNECT_DATA =

(INSTANCE_NAME = cl10g1)
)
)
With this setting I normally use the tnsnames.ora configuration for RAC (I was able to check RAC database only using tnsnames.ora not directly.
You  can try to remove the hostname and port from the db configuration for the RAC.
If the SID is equal to the name of the DB to check (the one in []) you can also remove the sid line from the configuration.
You can also try to connect with a telnet to the hostname and listener port to see if it answer (or better you can configure on the client the tnsnames.ora and do a tnsping to see if the instances are answering).
As you can see I don't do some checks on the RAC itselft or on the single instances... For example I don't test memreq and hitcache on the RAC and I don't check TblSpace, Extent, Rollback, locks, invalid objects on the single instances.
Please check also on the configuration file and remove all ending space after host or port or sid. I don't know if it can create problems (I'll check this also and remove those from the configuration option for the next version).
Let me know if this work for you or you have other problems.

Hi,
dbcheck.pl (and the other scripts in the package) use the CONFIG::IniFiles to read configuration data. CONFIG::Inifiles allow comment line starting with "#" and ";" but I think it will not recognize the "#" comment at the middle of a line so if you need comments you should put them alone on the line before or next to the line to comment on.
On some of the sample config file I've put some comment next to parameters and this could probably generate confusion. I'll change the sample config file and put this behavious also in the documentation I'm writing for the next version (the actual documentation is not really well written and organized).

Hi !
I want to use dbcheck.pl from
http://sourceforge.net/projects/hobbit-perl-cl/
.. but unfortunatley something is going wrong, i get only
"Connection Refused" Messages and no data  .. :-(
My config is below:
[SNIP]
...
dbcheck.ini:
oraclehome              = /opt/products/oracle-client/10.2g/
username                = XXXX
password                = XXXXXXXXXXXXXXXXXXXXXXX
[atlas_tag_db]
dbtype                  = Oracle
oraclerac               = yes
hostname                = lcg3d-a-v-4   # hostname of the rac instance n.2
sid                     = atlas_tag_db  # sid of the rac instance n.2
port                    = 1521          # port of listener on rac instance
I don't use this code, but your error output suggests that it's trying to
use your hostname, sid, and port from dbcheck.ini exactly as written,
comments and all.  I don't see anything in the sample dbcheck.ini file
that suggests that you can use trailing comments in the way that you are
doing, so perhaps you should try without those.
