[hobbit] dbcheck for RAC connections refused

This is what i normally do to check a RAC DB + single RAC instance in the configuration:

oraclehome              = /usr/local/oracle/10.2.0/client/
bbdisplay               = localhost
bbconncolumn            = ChkConn::fast
bbauditcolumn           = Audit::fast
bbtablespacecolumn      = TblSpace::fast
bbextentcolumn          = Extent::slow
bbhitcachecolumn        = HitCache::fast
bbmemreqcolumn          = MemReq::fast
bbrollbackcolumn        = RollBack::slow
bbinvobjcolumn          = InvObj::fast
bblockscolumn           = Locks::fast
bbsessioncolumn         = Session::fast
bbsessionuserlist       = yes
username                = userxxx
password                = pwxxxxx

[CL10G]
oraclerac               = yes
bbhitcachecolumn        = HitCache:notest
bbmemreqcolumn          = MemReq:notest

[CL10G1]
hostname                = itromdb21
bbauditcolumn           = Audit:notest
bbtablespacecolumn      = TblSpace:notest
bbextentcolumn          = Extent:notest
bbrollbackcolumn        = RollBack:notest
bblockscolumn           = Locks:notest
bbinvobjcolumn          = InvObj:notest

[CL10G2]
hostname                = itromdb22
bbauditcolumn           = Audit:notest
bbtablespacecolumn      = TblSpace:notest
bbextentcolumn          = Extent:notest
bbrollbackcolumn        = RollBack:notest
bblockscolumn           = Locks:notest
bbinvobjcolumn          = InvObj:notest


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

CL10G =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ITROMDB21)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = ITROMDB22)(PORT = 1521))
    (LOAD_BALANCE = no)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cl10g)
    )
  )

CL10G2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ITROMDB22)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cl10g)
      (INSTANCE_NAME = cl10g2)
    )
  )

CL10G1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ITROMDB21)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cl10g)
      (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.

Francesco

Hi, Franceso !

Thanks for the hint, it looks better/cleaner now, but the error is still exist ...

Any suggestions for further debugging ?

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.

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).
