First thing we need to check where the data files are being stored to do this all you need to do is log in as sysdba and then run ‘select * from dba_data_files;’ e.g. SQL> connect / as sysdba Connected. SQL> select * from dba_data_files; Once you have the location the syntax for adding the file is SQL> connect / as sysdba Connected. SQL> alter tablespace data_large add datafile '/lh0-mmm-sync/oracle/oradata/data0/data_large02.dbf' size 1g; Note: Oracle will create the data file for you, you don’t need to make the file though the OS or anything.

Found out the hard way on this that yes you can install snmpd on the xen domu machines but, you have a very limited amount of snmp mibs to play with, things you can not do unless you create your own snmp mib file.

We called it the Rubber Duck method of debugging. It goes like this: 1) Beg, borrow, steal, buy, fabricate or otherwise obtain a rubber duck (bathtub variety) 2) Place rubber duck on desk and inform it you are just going to go over some code with it, if that's all right. 3) Explain to the duck what you code is supposed to do, and then go into detail and explain things line by line 4) At some point you will tell the duck what you are doing next and then realise that that is not in fact what you are actually doing.
