Re: the ora certified masters cert, yet again

I simply think that its main value (other than the totally artifical value of being a common checklist item for hiring authorities now) is to get people to study, learn, and try things out.

I kind of regret perpetuating this thread now. It should have died gracefully on Wednesday really. You seem to have a quiet year ahead of you Don. Plenty of time left for hoop-jumping =) Unfortunately it now seems to be an even heavier financial undertaking than it used to be. It brings it home to you when people are talking about blowing their 'boat budgets' and suchlike. Rather than imposing mandatory course attendance it may have been an idea for Oracle to actually make the exams harder to encourage people to attend courses voluntarily and to increase the number of failures/retakes. Also it would have helped the image of the OCP program. They've just strengthened the evidence (if that were needed) of OCP being simply a useful revenue stream.

RE: the ora certified masters cert, yet again
My favourite question - because you need pretty much only this one to occupy the entire interview: Over there on the far wall is a 6x6m white board. Assuming the space is an 'Oracle database', start filling the blanks in terms of memory, disks, files, caches, buffer etc with all the connecting lines. Start broadly and continue generating more and more levels of detail until you want to stop or we want you to stop. We want to know your favourite and least favourite bits At the end you have a remarkable insight into: - their knowledge on oracle database + instance - their ability to convey information. We had one guy who drew a great level of detail but literally spent 50 mins with his back to us drawing with not a single word, after which he sat back down. - their ability to do it in front of a small audience (which I think is critical for a DBA - we don't want sit-in-the-corner-saying-nothing-zombies) - their pet peeves, for example, they'll be describing temp tspace and might throw in a man, i hate it when smon takes forever to clear up space or something to that effect - their priorities (if they spend half an hour on the spin_count parameter then maybe their barking up the wrong tree) - their honesty (one key element I look for is some point where they say I *DONT KNOW* how this bit relates to this bit) It is also very controllable - you can gently nudge them from one section of oracle to another - they might be describing redo logs and you can throw in so how would they get from here to a standby? etc etc. It normally works very well - although on one occasion we asked this of a candidate and he burst into tears and ran from the room :-( I went home feeling guilty...which eventually transformed itself into a sadistic and maniacal grin :-) Cheers Connor --- Rachel Carmichael [EMAIL PROTECTED] wrote: you should come out of lurk mode more often -- those are GOOD questions and I'm going to add them to the standard list :) --- Grant Allen [EMAIL PROTECTED] wrote: Rachel Carmichael[SMTP:[EMAIL PROTECTED]] wrote: this goes back to a thread from maybe a year ago... what sort of questions do you ask on interviews.

Re: Re: Re:MTS performance is too bad.
FINALLY , Everything is good now. Thank you for your replies. Bunyamin - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Friday, June 28, 2002 12:33 AM I suspect that if you are getting 4030s with 50 concurrent users that you will get NO benefit from MTS, in fact it will likely cause just the problems you are seeing and you will start to get 4030s sooner than you would have before. MTS is not appropriate as a tool to address your 4030 errors if the sessions are not inactive for more than a few seconds. If the concurrent sessions are very active (check v$session's last_call_et field) and you are still running into 4030s than MTS will not help you, and can actually cause a performance hit (CPU) that is scary. The key thing to remember is that MTS provides SCALABILITY, performance is indirectly affected if at all. If you are running into 4030s there are a number of other approaches you can take as well. Application tuning is the best place to start, but more often then not, not possible. Then go to the obvious (that others have mentioned) like using statspack to get a look at the usage of your buffer cache. In your case you may have to reduce the size of your SGA to allow for more user space. Don't fall for the buffer cache hit ratio needs to be x%. If you are in an application env where most blocks are rarely seen in more than one query then you need a different approach to buffer cache tuning than hit %. This is a book in and of itself, but fairly intuitive. Given that you are stuck with your current application, the very first thing you also will want to look at is the Orastack utility to reduce the memory usage of each server process' stack. I have seen DBAs in your situation have their 4030s resolved with this alone. The other is upgrading your OS (or properly setting it) to NT EE or Win2k AS. This will allow you to use a 3gb process size. If you haven't done this it will surely fix your memory shortage (at least until you get another 50 users :)). You can also scale out by adding more nodes with OPS, although I'd strongly suggest that you move to 9i before doing this! Finally, you can use OPS/RAC on a single box, a bit of a fancy trick, but it allows you to have multiple instances if you have the system memory available. Ramble, ramble, ramble, for more info you can come to my presenation at OpenWorld (or just send more info/questions!)

What ever I did did not give the same performance as dedicated connections even not approached. Bunyamin - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thursday, June 27, 2002 4:53 PM You really don't need MTS with no more than 50 concurrent users unless you are running into ora-4030s or other memory problems. When you say performance is a problem, have you check OS swapping of memory to disk? Your SGA might be too big (with AS and the 3GB switch no bigger than 3GIG, without the 3GB switch only 2GB) and end up swapping out to disk. You also need to make sure that only OLTP users (users with short txns, NOT long running batch jobs, big updates, etc) are connecting via MTS. All batch/DSS type users should be connecting via dedicated server. You can have them specify this in their tnsnames.ora. That said, your MTS config is WAY out of whack given the number of concurrent users: You only need ONE dispatcher to start with. Change dispatchers to 1 unless you have multiple NICs you are working off of for a particular segmentation of users. (50 dispatchers would be appropriate for about 12,000 Concurrent users) If your total number of concurrent OLTP users is truly 50 set your min servers to 60. Max servers is fine. You should also set your large pool instead of a massive shared pool, all kinds of reason for doing this!! If you have a chance go to borders or barnes and noble, sit down and read chapter 7 (Oracle Connectivity) of my book Oracle9i for Windows 2000 Tips Techniques. It covers the setup, monitoring and basic tuning of MTS.

There r some waits happening on the undo blocks (non-system) but could not figure out whether this could possibly cause such a slowdown of the system. Also there were some indexes newly created on some of the tables which are causing problems. What's the best approch anyways to hunt down the problem in a situation like this ? - Chetan BigP<[EMAIL PROTECTED]>wrote: cheten ,find processid of the application , look into database waits , that will give u some hint .Also look into db buffers to find if there are full table scans flushing db buffer . btw Did u ran statistics ?-Bigp - Original Message - From: Chetan To: Multiple recipients of list ORACLE-L Sent: Wednesday, June 26, 2002 3:38 AM Subject: Oracle Performance Tuning steps Hi guys , Need some help. Actually we are looking here at a Oracle 8.1.7 db on HP-UNIX. The application was running fine uptil yesterday. Suddenly a part of the appln is running extremely slow. I can not figure what might be the problem. Wanted to track this down asap. Here is some information about the db. Database size - 20GB Optimizer - CHOOSE Disk Structure - RAID 1+0 No. of processors - 4 Block Size - 8K Archivelog mode : ARCHIVELOG Please tell me what should be the ideal way I should try to trace the problem. I thought of running UTLBSTAT/UTLESTAT or STATSPACK and asked the user to run that part of the appln. Has anybody worked with STATSPACK before ? Can anybody tell me what should accurate and fastest way to hunt down the problem ? I think its something to do with indexes or changes in the queries. Also can someone tell me the ideal backup strategy for this database considering the fact that it's a 24x7 system. Thanks in advance . Chetan Chindarkar Do You Yahoo!?
