Hi

I'm trying to use debug option in toad 9.7 but it shows this message "UNABLE TO FIND RAC CONNECTION INFORMATION FOR RAC (INST_ID=1)"

I found some information and it says that Oracle doesn't support debugging accros RAC instances. We have a RAC instances and It was working fine until now but all of a sudden i faced the error message today.

Even I followed some instructions to create additional entries in tnsname.ora for each RAC nodes without load balancing parameter but it fails and faced the same error message.

Following is the tns entries.

Actual Entry

RAC =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = mcmsdb)(PORT = 1521))
   (FAILOVER=on)
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = mcmsdrac)
     (FAILOVER_MODE = (TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))
   )
 )

Instance 1

RAC1 =
 (DESCRIPTION =
   (ADDRESS =
     (PROTOCOL = TCP)
     (HOST = xx.xx.xxx.xx)
     (PORT = 1521)
   )
   (CONNECT_DATA =
     (SERVICE_NAME = mcmsdrac)
     (instance_name = mcmsdrac1)
   )
 )

Instance 2

RAC2 =
 (DESCRIPTION =
   (ADDRESS =
     (PROTOCOL = TCP)
     (HOST = xx.xx.xxx.xx)
     (PORT = 1521)
   )
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = mcmsdrac)
     (instance_name = mcmsdrac2)
   )
 )

Please help me to get rid out of this issue.

Can you give it a try by making slight change in your tnsnames.ora file ? Just add the couple of lines (marked bold) in RAC entry.

RAC =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = mcmsdb)(PORT = 1521))
  (ADDRESS = (PROTOCOL = TCP)(HOST = <HOST FROM RAC1>)(PORT = 1521))
   (ADDRESS = (PROTOCOL = TCP)(HOST = <HOST FROM RAC2>)(PORT = 1521))
  (FAILOVER=on)
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = mcmsdrac)
     (FAILOVER_MODE = (TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))
   )
 )

RAC1 =
 (DESCRIPTION =
   (ADDRESS =
     (PROTOCOL = TCP)
     (HOST = xx.xx.xxx.xx)
     (PORT = 1521)
   )
   (CONNECT_DATA =
     (SERVICE_NAME = mcmsdrac)
     (instance_name = mcmsdrac1)
   )
 )

RAC2 =
 (DESCRIPTION =
   (ADDRESS =
     (PROTOCOL = TCP)
     (HOST = xx.xx.xxx.xx)
     (PORT = 1521)
   )
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = mcmsdrac)
     (instance_name = mcmsdrac2)
   )
 )
