I have 5 oracle databases and they all are on different machines. i want to fetch data(tablespace data) from db to excel.
here is my macro code
Dim Conn As New ADODB.Connection
Dim RS As New ADODB.Recordset
Dim Cmd As New ADODB.Command
Dim sqlText As String
Dim Row As Long
Dim Findex As Long
Dim STD As Worksheet
Dim X As Long
Dim UID As String
Dim PWD As String
Dim Server As String
UID = "monitordb"
PWD = "monitor1"
Server = "STD"
Set STD = ActiveSheet
Cmd.ActiveConnection = Conn
Cmd.CommandType = adCmdText
sqlText = "select sum(a.tots/1048576) Tot_Size,sum(a.sumb/1048576) Tot_Free,round(sum(a.tots-a.sumb)*100/sum(a.tots),2) Pct_used,sum(a.largest/1024) Max_Free,sum(a.chunks) Chunks_Free from(select tablespace_name,0 tots,sum(bytes) sumb,max(bytes) largest,count(*) chunks from dba_free_space a group by tablespace_name union select tablespace_name,sum(bytes) tots,0,0,0 from dba_data_files group by tablespace_name) a group by a.tablespace_name order by a.tablespace_name"
Cmd.CommandText = sqlText
Set RS = Cmd.Execute
For X = 0 To 4 ' Number of columns returning minus 1
'Data.Cells(1, X + 1) = RS.Fields(X).Name
Do While Not RS.EOF
Row = Row + 1
For Findex = 0 To RS.Fields.Count - 1
STD.Cells(Row + 2, Findex + 67) = RS.Fields(Findex).Value
I am able to connect through sqlplus on all machines but when i run the above code it gives me TNS error..
ORA-12154- TNS could not resolve the connect identifier specified..
Each database use same port 1527 and only one of them is able to fetch the data. and if i remove that database from client then the other one starts connecting. I think problem is due to same port number.
Entries in the listener.ora file was made throough oracle client only 32bit.
and i have installed both 10g and 11g client on my local machine.
