HI
Thanks for the reply.
I have set the alert the way you asked me do.
However i am not getting an alert when the tablespace get full by 85%.
I am not getting alert to our mail.
Could you please let me know do we need to do anything else.
I tried using through user defined sql metrics.
The query which i am using is
DECLARE
Type v_filenames is table of dba_data_files.FILE_NAME%type
index by pls_integer;
filename v_filenames;
type v_currsize is table of dba_data_files.BYTES%type
index by pls_integer;
currsize v_currsize;
type v_maxsize is table of dba_data_files.MAXBYTES%type
index by pls_integer;
maxsize v_maxsize;
mark75 number;
mark500 number;
n_maxsize number;
i pls_integer default 1;
total_files sys.dba_data_files.BYTES%type;
SUM_BYTES sys.dba_data_files.BYTES%type;
SUM_MAXBYTES sys.dba_data_files.MAXBYTES%type;
BEGIN
SELECT SUM(BYTES)/(1024*1024),SUM(MAXBYTES)/(1024*1024) INTO sum_bytes,SUM_MAXBYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME='&&1';
select SUM(bytes*4/3-maxbytes)/(1024*1024),500-SUM(MAXBYTES)/(1024*1024) into mark75,mark500 FROM DBA_DATA_FILES WHERE TABLESPACE_NAME='&&1';
if mark75>=mark500 then
n_maxsize:=mark75;
else
n_maxsize:=mark500;
END IF;
will the above query will work.
I dont what condition to put in my case.
I want to put this condition
if mark75>=mark500 then
n_maxsize:=mark75;
however i am not using it in where clause.
Thanks.
