RE: POLL: Database to DBA ratio
Title: RE: POLL: Database to DBA ratio In our environment, each DBA supports a certain number of databasesthat are his/her 'primary' databases (all the way from Test/Dev/Accept/Production). The same person is 'secondary' or 'tertiary' for others.We follow a standardizedsetup (somewhat modified OFA) for *all* of these databases, with standardized, but different, passwords for sys/system/production schema accounts that can be easily 'figured out' by DBA team members.Those arechanged routinely!All DBAs are on call all of the time. Every 2 hours the automated pagingmechanism/Operations is made 'aware' of who's available via our own DBA Web App, that keeps track of who's in and who's out as well as the 'primary','secondary','tertiary' matrix by databasenames.

RE: POLL: Database to DBA ratio
Depends on what you consider to be 'real' production issues. We get pages for production and development, for things that really should be planned change control, for idiot user stuff, as well as the regular db/listener down, ora-0600 and the other standard stuff. With most of the applications being developed in-house by folks that don't really know anything about how Oracle really works, probably 60% is fire-fighting. It's a lot better than it used to be however... We had a reorg three years ago that split the then-DBA group into two sides - Plan/Build, and Run. The Run folks were solely responsible for the pager. Consequently, all of the Run folks quit right after I came on staff. So, for 6 months or so it was me and two Sybase guys who were hired shortly after me and did the crash-course route into Oracle. That was brutal.

RE: POLL: Database to DBA ratio
I'd twelfth (or whatever number we are upto by now) the comments so far on how it isn't a fair measure. For what its worth we now have 19 Oracle instances and 7 sql server databases, probably 50+ schemas. You can take your pick as to what you mean by database. We have 3 dbas. One thing that does complicate this is that most of the databases get there own server because of the slightly mad project driven way budgets work (like there is no budget for database servers but each team will have a budget for software and hardware). Sometimes it seems really quiet and stereotypically govt overmanned, othertimes I don't see my daughter awake for a week at a time.

RE: POLL: Database to DBA ratio
FWIW... There is no fair measure in my opinion. It depends on how well a model environment was set up in the first place for each database instance. A first class model environment needs less maintenance in general than a hack environment. You spend much less time in break/fix mode as a result and more time in optimizing/tuning for zero administration (shameless plug - Live 2003 - White Paper Presentation - Where there's smoke there's fire... Firefighter or Arsonist) Many times we are our own worst enemies and unintentionally trap ourselves into break/fix mode 7X24. On the other hand, sometimes you inherit these environments and there is no alternative but break/fix because there is no time. All of that having been said, here's some thoughts... 1. Use any off the shelf software to help you build a model environment which includes lights out proactive monitoring that you are comfortable with. 2. Ditto for backup software 3. Where you can't use off the shelf software, use the minimum number of scripts possible to help you manage your database and provide critical email alerts daily for non-critical maintenance and only send pages for critical failures about to happen. 4. Keep a detailed workbook of every utility script. If you wrote it once, you will probably need it again so why not save it and document it for later use. 5. Make EVERY database environment as close to identical in OFA layout as possible. I've run teams where the ratio is over 100:1 and they run like a swiss clock because of excellent planning and execution. I've also been in shops where 4:1 was nearly impossible because the initial setup and on going configuration of every database is completely different and no consistent implementation of installation, configuration, monitoring and maintenance is in place. In the 4:1 shops... my primary goal was to get the shop to a consistent configuration in a minimalist mode at first and then evolve the more sophisticated monitoring and tuning aspects of the environment. Don't know if this helps. If not, find me at Live 2003 and let's talk.

One thing that does complicate this is that most of the databases get there own server because of the slightly mad project driven way budgets work (like there is no budget for database servers but each team will have a budget for software and hardware).

In my
shops we use a similar matrix to this for management and assignment. In
short, on-call rotates weekly and the "on-call" responsibility covers non
business hours (eg: 7pm - 8am). The remainder of the time the environment
DB owner has responsibility. The (A) indicates an automated process, each
DBA has designated databases for all management during normal business
hours. The on-call DBA handles off-hours work. The matrix is as wide
as you have database instances. Here's an example from an environment I
worked on. The script name column is the exact path/name for the script
supporting automated functions, or, the name of the script to manually check

33 DBA's to one database? That's pretty danged good! :) Seriously, this is a question that comes up every so often within Oracle as well, as clients ask Oracle employees what should be expected. There's no simple answer to it. As you might expect, the answer is it depends. :) Depends on (a non-exhaustive list): 1. Requirement for 24x7 DBA coverage 2. Complexity of database 3. Type of applications using the database 4. Database type (OLTP, DW etc.) 5. Number of tiers (two tier, three tier etc.) 6. Amount of input required into development of apps (tuning support and so on) And lots more as well. Pete Controlling developers is like herding cats. Kevin Loney, Oracle DBA Handbook Oh no, it's not.

RE: POLL: Database to DBA ratio
Chuck I think this is a slippery argument. It may appeal to managers but can lead to bad decisions long-term. Does anyone remember years ago when managers would measure COBOL programmers LOC (lines of code)? Just measure how many lines of code each programmer writes each day and vola! you know which are your best programmers -- right? But I would match 5 production instances against a single test instance with a group of cranky developers who are normalization bigots. I maintain about 15 instances by myself, so by your standards I'm a real slacker. I've tried to group applications into common instances, for ease of maintenance and better use of system memory. Maybe I should change that policy so I can boost my numbers ;-) Dennis Williams DBA, 40%OCP, 100% DBA Lifetouch, Inc.

Now we have mega-sensitive instances.. needing Now we have 3:1 Many of them have 3-way upgrades each year and we only have 8 months to do it in.. Saying all that is to say...its not apples to apples.. What we do- is, we map all the ongoing projects and resource out the dba's and when new projects come...we have a tool to communicate the resource requirements to management... something they understand when you say You want that project.. we need more resources... or what other project do you want to cancel.

RE: POLL: Database to DBA ratio
We currently have twenty-one databases, thirteen production and eight which are either test or development. Of the thirteen production databases five need to be up on a 24 X 7 basis; physics experiments and or accelerator monitoring depend on them. Nine of the production databases are Oracle back ends for third-party products including Peoplesoft and Remedy. All the above databases all administered by one DBA. We do have Peoplesoft Administrators, Remedy Administrators, System Administrators to take some of the load off, but I am responsible for the installation, upgrade, maintenance, tuning, and backup of all databases and Oracle software. This includes Internet Developer Suite and Internet Application Server, although as to the latter, I'm in the process of unloading it. This all works quite well most of the time. A problem can arise when I must devote my attention to fixing a pressing problem. In which case the reading of some reports on the non-24x7 databases may be postponed and the database then pages me about trouble which I could of fixed proactively had I read the reports. Larry E. talks of having a single database with third party certifications to consider and with multiple applications requiring 24 X 7 service this is impossible. We do of course have to negotiate down times for even the 24 X 7 applications, but their operational schedules make it impossible to have them all down at once. I do get vacations. A cell phone and a wide-area pager is a necessity, and I don't necessarily have to be at work from eight to five.

RE: POLL: Database to DBA ratio
A simple num of databases to DBA ratio is quite meaningless. You need to take into consideration of at least the following: o Size of the database, transaction volume. What kind of up time your database needs to provide. o Complexity of the database and application which run on top of it. Number of objects, tables, stored procedures. Is there replication, partitioning, object types, RAC/OPS, etc involved? o Does the DBA also do some SA work, or development work or design etc. o How frequent is your development cycle. I am sure others will have lots of things to attribute. But you can't just say I have NNN number of databases and therefore need NN number of DBAs.

Re: POLL: Database to DBA ratio
Chuck, I support 17 development, 2 production oracle databases, 3 DB2/MVS databases and 1 SQL Server. A coworker supports only 1 application and that is in UAT/Dev environment but it is a highly active application in the multi-Terabyte range (UDB). We have external prod. support for some of our apps (IBM). I think how many a DBA can support will depend upon a number of things such as (by no means a complete list): - Production Support and/or App. Dev support - Frequency of change to an application. Some stay in a constant state of change. - Complexity of system (ERP, n-tier, custom, vendor) - Procedures/processes/technology to allow easier support of multiple systems.

Re: POLL: Database to DBA ratio
Chuck, That's not really a good measure. It really depends on a number of things. * number of users * number of apps * size of db's * quality of apps ( some require more work than others ) * amount of new development * lots more I can't think of at the moment... Best thing to do is document the advantages of additional staff. If it can save the company $$, they will go for it. The savings will come in from less downtime, apps get put in production sooner, ...

RE: POLL: Database to DBA ratio
We're 5 DBA including the team leader. We have 130 Oracle DB + 40 Sql Server 2000 + 6 DB2 mainframe. And we're doing development (data modeling ) and supposed to be involved in architecture now. Also, you should take in account if it's production or development work. Are you involved in data modeling ? on the unix side ? ... I hope you send all answers in a nice excel spreadsheet !

Re: POLL: Database to DBA ratio
You are the first reply out of at least 20 (public and private) who has a larger ratio than we do. The average seems to be somewhere around 20 so far. As many have pointed out, there are other factors to be considered if you're trying to measure the DBA's workload. I'm not trying to be that precise though. The DB to DBA ratio is close enough for me. BTW in case anyone is interested we have 2 DBAs managing 66 databases. 25 are dev/test. 41 are production. Of the 41, 39 are 24x7, 6 are over 100g, one is over 1000g. These #'s are more accurate that what I reported off the top of my head to a few in private. - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Tuesday, March 11, 2003 1:31 PM Consider yourself lucky.
