Howard Rogers has done a post on his blog that is the site Dizwell worth it ? Do post your opinion. If he plans to close it down, we will miss a great resource for Oracle. Sidhu Comments Comment by Aman Sharma on 2007-10-23 09:20:00 +0530 Fingers crossed that he wont do that and thats the voice of all(almost) too!Hope he takes the right decision. Cheers, Aman….
Tom Kyte did a post on his blog about posting of reviews of questions on Asktom. In a nutshell the reviews not related to the original question will be ignored/deleted (not decided yet, as Tom said). As other people said in the comments, personally I too like this idea very much. Earlier, many times, there were questions which started with someone asking about appropriate SGA size, then there were some other twists and discussions and then the thread ended in discussion about good or bad authors or something similar light years away from the original topic. ...
Today I was checking Eddie Awad’s blog. From there I came to know that Oracle has started Official Oracle Wiki hosted by Wetpaint. Check out. I just made my login. Hoping to contribute whatever little I can Sidhu Comments Comment by Frank on 2007-11-09 03:10:00 +0530 Another GREAT wiki to contribute to is http://www.orafaq.com/wiki Comment by Sidhu on 2007-11-15 07:48:00 +0530 Yea Frank Indeed this website orafaq.com is a good one. Pretty good articles and content. ...
Today, I was following a thread on Oracle Forums. Someone asked a question about UNDO tablespace wrt to a scenario. The question was: There is a database and its hot backup is taken on Friday. Now for Saturday, Sunday and Monday there are archive logs but no backups. Suppose the machine crashes on Monday. After we restore the database to Friday (from backup), recovery will happen. As UNDO tablespace is of Friday so it has no information related to transactions that happened on Saturday, Sunday and Monday. So in the end of recovery process when we need to rollback some transactions from where that required information will come ? ...
Being a new kid on the block, I think, my post will not fire any serious and “scary” discussion as it has happened many times in the past. Just writing my experience. Whenever I search something related to Oracle in Google there are few sites that are bound to come up in the very first results ( No surety about the relevance and completeness of the content, though). Today I was searching about scheduling new jobs in oracle and I was, sort of, surprised to see the results [Though, I got from there, what I was looking for & I would like to say Thanks for that]. Many other times also, I have seen these websites pop up like anything. ...
I was searching for some good tutorials on awk. Found a very nice (brilliant indeed) article on Oracle website by Emmett Dulaney. A very good introduction for beginners. I searched for some other links as well. Have a read: 1. AWK: The Linux Administrators’ Wisdom Kit 2. A Guided Tour Of Awk 3. AWK Programming 4. UNIX Utilities - awk Happy awk’ing :) Sidhu
Today Stumble gave me a link to an article on a website. That article talks about a guy Virgil Griffith who wrote a piece of software to track IP addresses of the people, editing the Wikipedia content. Some really interesting things came up: Apple attacking Microsoft and then Microsoft taking revenge. Have a look at the full article. It makes an interesting read. Read more about this guy on Wikipedia here. Sidhu
Few days back, I had to give Oracle DBA training to a group of about 20-25 semi-technical people (Semi-technical, because most of them were not really DBA kinda folks doing all the techie stuff with Oracle, but in-fact having learned some bits & bytes of Oracle sometime back and these days looking into application functionality from technical perspective). I, having just about 10 months of experience with DBA profile, had to cover, everything about Oracle starting from creating database and up to performance tuning :) Its really an interesting job if the audience is good. But not an easy game. You have to know everything and have to be ready to answer people’s queries (some stupid & dumb questions also :) I had to cover a total of about 350 slides in a day or less. So at times, really went fast and skipping some of things. It was a nice experience as a whole :) ...
Many times, we are required to restore a database from an export dmp file. Its a simple task but sometimes there are some issues left like invalid objects or some objects missing, in the newly created database. Following steps, followed in order can help in creating an error free database: Create a blank database:The very first step is to create a blank database which is to be used as the target database. That can be done using Database Configuration Assistant. (In last step of the DBCA, change redo log file sizes to 500 MB each (or some appropriate values depdening upon the size of the databaes), as during import, lot of redo will be generated, so large redo size helps in that scenario) ...
The day when Oracle 11g was made available for download on OTN, there was sort of, flood of posts in the Oracle blogsphere. Here is a quick recap of few of the posts (Whatsoever I could find through OraNA and my Netvibes) Eddie Awad about 11g, I think he was the first one to post Then Doug Burns here Howard on installing 11g Another interesting article from Howard Tim Hall about 11g Tim Hall on installing 11g ...
