Scott, Is this job task analysis menat to be specific to what you do/ will do at your current site or to cover general activities thta a DBA may come across.
If it is the first option it appears that you are covering almost every Oracle feature available so you must be very busy. If it is the second option then I suspect very few DBAs could honestly say that they have worked and know well every task on the list and indeed would not get chance to use them all at any one site. However a key word in the list is *understand*. That means different things to different people. These could be grouped by 1) Deeply understand , have used extensively, raised bugs on the product etc 2) Have read up on and not all about in principle and would expect to implement with no great difficulty 3) Have heard of and not much else 4) Those who can talk bulls* and are at stage 3 but are at level 1 at the CV stage. Overall I think I am asking 'what is the purpose of this task list' John -----Original Message----- Sent: 01 April 2003 22:14 To: Multiple recipients of list ORACLE-L I am putting together a prelimanary job task analysis for Oracle DBA's and would like some input from you hardworking DBA's on this list.
