RE: Oracle Job Task Analysis
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.

RE: Oracle Job Task Analysis
John, That is a good question. What is the purpose of this task Analysis? I am trying to see what most DBA's perceive as what is the most important things to learn so you can manage an Oracle Database. An example would be Learning Oracle Architecture. If you are a small, medium or large company, Architecture is probably the most important. Within the Oracle Architecture what is the most important for me to learn to job. Learning the SGA structures and how to size them. Learning the physical structures of the database and how to manage them. So if you wanted to be a DBA with Oracle what major Oracle components do think you need know to accomplish that job and what sub-components are important? If I was a DBA in a company that does a lot of interne t activity what do I need to know? If I run a 7X24 shop what do I need to know and so on. Small, medium and Large companies will require a base knowledge and as you get more niche you will need to understand other components of Oracle. We also need to look at what is niche. RAC is niche but becoming more mainstream. What do I need to know to run a HA shop, however Context, XML and Spatial are in the database, while these are niche they are as common as RAC. So what I am looking for is what people perceive to be the most common components needed to do their Job. Another interesting question is do I need to learn how to create the database and other database objects using manual methods or do I use DBCA and EM to do my job. Is knowing the GUI sufficient for me to be a DBA? These are why I am asking these questions. I really want to know what you really need to know right down to you only need to know it if you implement the option. Does this help?

Re: Oracle Job Task Analysis
Scott, This is quite a list you have compiled. I wouldn't subtract anything. The only thing I could think of to add was in the Scalability section. This section seems to concentrate on using Oracle technologies to enhance scalability, but there is another level that I think needs to be considered as well. The ability to scale ( or not ) is built into an application. An app that calls 'select something from dual' in every transaction is going to have problems. So will apps where the developers insist on trying to do everything in code rather than relying on the database. A DBA should be able to recognize when this is happening. The best course is to have an adivisory position in this regard when an app is being developed. Doesn't often happen this way though. A DBA should be able to demonstrate common developer habits that inhibit scalability, and how to recode these so that they are more scalable. Being able to do so in PL/SQL is sufficient, and in fact preferable. Any chance of us seeing the completed analysis?
