• Upgrade Workshop in Wellington - Recap

  - by Mike Dietrich

  Wow! Wellington is really a wonderful city - except for the weather situation But it was the first time that Roy and me did arrive to a workshop with a ferry boat. We flew in on Friday to Christchurch (btw, this was the longest customs and border control I've ever went through - and I traveled to Israel by Bus via Allenby Bridge from the West Bank some years ago - it took us two hours to go through immigration and customs in the night from Friday to Saturday) and drove up the Southern Island. Very nice Great landscapes, great wines and great people! I'f you'd like to download the slides please download them from the Slides Download section to your right.

• How to SET TIMING ON for parallel upgrades to 12c?

  - by Mike Dietrich

  Have you asked yourself how to get timings in an Oracle Database 12c upgrade for all statements? When you run the parallel upgrade via catctl.pl, the parallel upgrade Perl driving script in Oracle Database 12c, you may also want to get timings written in your logfile during execution. As catctl.pl does not offer an option yet the best way to achieve this is to edit the catupses.sql script in $ORACLE/rdbms/admin as this script will get called all time over and over again throughout all steps of theupgrade run. Just add these lines marked in RED to catupses.sql and start your upgrade: Rem =============================================Rem Call Common session settingsRem =============================================@@catpses.sql Rem =============================================Rem  Set Timing On during the UpgradeRem =============================================SET TIMING ON; Rem =============================================Rem Turn off PL/SQL event used by APPSRem =============================================ALTER SESSION SET EVENTS='10933 trace name context off'; -Mike PS: This may become the default in a future patch set

• Where did my hard drive go?

  - by Mike Carron

  I installed XBMCbuntu 11.0 to my Zotac Zbox AD03 with an OCZ Reflex 4 256gb SSK. The install worked fine and I was getting accustomed to the appearance and operation. When I attempted to boot from power-off the BIOS could no longer find the SSD. It refused to boot and when I checked in the BIOS, the SSD was missing from the boot list (it was there prior to the install). I rebooted from the install CD but when the system started it could not find the SSD. I replaced the SSD with a fresh one of the same type and reinstalled XBMCbuntu. This time I rebooted from the system several times successfully but when I shut it down and tried to cold boot, this drive was also gone. Does the installation do something strange to the boot record that could cause a BIOS to lose it? How do I fix this? mike

• Is it illegal to forward copyrighted content? [closed]

  - by Mike

  Ok, this may be a strange question, but let's start: If I illegally download a movie (for example...) from a HTTP Web Server, there are many routers between me and the Web Server which are forwarding the data to my PC. As I understand, the owners of the routers are not legally responsible for the data they forward (please correct if I'm wrong). What if I would install a client of a peer-to-peer network on my PC and this client (peer) would forward copyrighted content received from peers to other peers? Hope someone understand what I mean ;-) Any answer or comment would be highly appreciated. Mike Update 1: I'm asking this question because I want to develop a p2p-application and try to figure out how to prevent illegal content sharing/distribution (if forwarding content is really illegal...) Update 2: What if the data forwarded by my peer is encrypted, so I'm technically not able to read and check it?

• Separating physics and game logic from UI code

  - by futlib

  I'm working on a simple block-based puzzle game. The game play consists pretty much of moving blocks around in the game area, so it's a trivial physics simulation. My implementation, however, is in my opinion far from ideal and I'm wondering if you can give me any pointers on how to do it better. I've split the code up into two areas: Game logic and UI, as I did with a lot of puzzle games: The game logic is responsible for the general rules of the game (e.g. the formal rule system in chess) The UI displays the game area and pieces (e.g. chess board and pieces) and is responsible for animations (e.g. animated movement of chess pieces) The game logic represents the game state as a logical grid, where each unit is one cell's width/height on the grid. So for a grid of width 6, you can move a block of width 2 four times until it collides with the boundary. The UI takes this grid, and draws it by converting logical sizes into pixel sizes (that is, multiplies it by a constant). However, since the game has hardly any game logic, my game logic layer [1] doesn't have much to do except collision detection. Here's how it works: Player starts to drag a piece UI asks game logic for the legal movement area of that piece and lets the player drag it within that area Player lets go of a piece UI snaps the piece to the grid (so that it is at a valid logical position) UI tells game logic the new logical position (via mutator methods, which I'd rather avoid) I'm not quite happy with that: I'm writing unit tests for my game logic layer, but not the UI, and it turned out all the tricky code is in the UI: Stopping the piece from colliding with others or the boundary and snapping it to the grid. I don't like the fact that the UI tells the game logic about the new state, I would rather have it call a movePieceLeft() method or something like that, as in my other games, but I didn't get far with that approach, because the game logic knows nothing about the dragging and snapping that's possible in the UI. I think the best thing to do would be to get rid of my game logic layer and implement a physics layer instead. I've got a few questions regarding that: Is such a physics layer common, or is it more typical to have the game logic layer do this? Would the snapping to grid and piece dragging code belong to the UI or the physics layer? Would such a physics layer typically work with pixel sizes or with some kind of logical unit, like my game logic layer? I've seen event-based collision detection in a game's code base once, that is, the player would just drag the piece, the UI would render that obediently and notify the physics system, and the physics system would call a onCollision() method on the piece once a collision is detected. What is more common? This approach or asking for the legal movement area first? [1] layer is probably not the right word for what I mean, but subsystem sounds overblown and class is misguiding, because each layer can consist of several classes.

• Easiest turn-base games you can think of?

  - by Edgar Miranda

  I'm planning to get into the process of programming multiplayer turn-base games. I would like to start off by making some of the simplest (yet fun) multiplayer turn-base games out there. What are some that you can provide? For example... Tic-Tac-Toe Rock-Paper-Scissors Checkers Some not so easy games... 4 in a row chess poker In terms of "ease" of implementation I'm mainly looking at logic. For example, Rock-Paper-Scissors has very simple logic, while chess has logic that is more complicated. So far I have the following: Hexagon Heroes of Might and Magic Nine Men's Morris Connect 4 21 (card game) Pen the Pig (The Dot game) Memory Match

• How important is a single-player mode in a 2-player game?

  - by Davy8

  So say you have a 2 player game, taking Chess as an example (except it's an original game with no ready-to-go AI available). Let's say there's also a social-aspect to the meta-game, so let's say it's a Chess game on Facebook where you can challenge your friends. How important is it to have a single-player mode, knowing that an AI will need to be created (I've done minimax AI for tic tac toe, but nothing too sophisticated)? Is it important enough that it should be in the initial launch of the game? Can it wait for a future iteration (knowing that being hosted on the web means the game can be updated at any time)?

• Terms and conditions for a simple website

  - by lonekingc4

  I finished building a website for an online chess club which I am a member of. This is my first website. The site has blogging feature so the members can log in and write blog posts and comment on other posts. The membership is limited to users of an online chess site (freechess.org) and any member of that site can join this site as well. I was wondering, is it needed to put up a terms and conditions for my new website? If so, can I have a model of that? I searched and found some models but they are all for big sites that have e-commerce etc.

• Upgrade to 11.2.0.3 - OCM: ORA-12012 and ORA-29280

  - by Mike Dietrich

  OCM is the Oracle Configuration Manager, a tool to proactively monitor your Oracle environment to provide this information to Oracle Software Support. As OCM is installed by default in many databases but is some sort of independent from the database's version you won't expect any issues during or after a database upgrade But after the upgrade from Oracle 11.1.0.7 to Oracle 11.2.0.3 on Exadata X2-2 one of my customers found the following error in the alert.log every 24 hours: Errors in file /opt/oracle/diag/rdbms/db/trace/db_j001_26027.trc: ORA-12012: error on auto execute of job "ORACLE_OCM"."MGMT_CONFIG_JOB_2_1" ORA-29280: invalid directory path ORA-06512: at "ORACLE_OCM.MGMT_DB_LL_METRICS", line 2436 ORA-06512: at line 1 Why is that happening and how to solve that issue now? OCM is trying to write to a local directory which does not exist. Besides that the OCM version delivered with Oracle Database Patch Set 11.2.0.3 is older than the newest available OCM Collector 10.3.7 - the one which has that issue fixed. So you'll either drop OCM completely if you won't use it: SQL> drop user ORACLE_OCM cascade; or you'll disable the collector jobs: SQL> exec dbms_scheduler.disable('ORACLE_OCM.MGMT_CONFIG_JOB');SQL> exec dbms_scheduler.disable('ORACLE_OCM.MGMT_STATS_CONFIG_JOB'); or you'll have to reconfigure OCM - and please see MOS Note:1453959.1 for a detailed description how to do that - it's basically executing the script ORACLE_HOME/ccr/admin/scripts/installCCRSQL - but there maybe other things to consider especially in a RAC environment. - Mike

• Elastic versus Distributed in caching.

  - by Mike Reys

  Until now, I hadn't heard about Elastic Caching yet. Today I read Mike Gualtieri's Blog entry. I immediately thought about Oracle Coherence and got a little scare throughout the reading. Elastic Caching is the next step after Distributed Caching. As we've always positioned Coherence as a Distributed Cache, I thought for a brief instance that Oracle had missed a new trend/technology. But then I started reading the characteristics of an Elastic Cache. Forrester definition: Software infrastructure that provides application developers with data caching services that are distributed across two or more server nodes that consistently perform as volumes grow can be scaled without downtime provide a range of fault-tolerance levels Hey wait a minute, doesn't Coherence fullfill all these requirements? Oh yes, I think it does! The next defintion in the article is about Elastic Application Platforms. This is mainly more of the same with the addition of code execution. Now there is analytics functionality in Oracle Coherence. The analytics capability provides data-centric functions like distributed aggregation, searching and sorting. Coherence also provides continuous querying and event-handling. I think that when it comes to providing an Elastic Application Platform (as in the Forrester definition), Oracle is close, nearly there. And what's more, as Elastic Platform is the next big thing towards the big C word, Oracle Coherence makes you cloud-ready ;-) There you go! Find more info on Oracle Coherence here.

• Grid Infrastructure Management Repository (GIMR) database now mandatory in Oracle GI 12.1.0.2

  - by Mike Dietrich

  During the installation of Oracle Grid Infrastructure 12.1.0.1 you've had the following option to choose YES/NO to install the Grid Infrastructure Management Repository (GIMR) database MGMTDB: With Oracle Grid Infrastructure 12.1.0.2 this choice has become obsolete and the above screen does not appear anymore. The GIMR database has become mandatory.  What gets stored in the GIMR? See the documentation here See the changes in Oracle Clusterware 12.1.0.2 here: Automatic Installation of Grid Infrastructure Management Repository The Grid Infrastructure Management Repository is automatically installed with Oracle Grid Infrastructure 12c release 1 (12.1.0.2). The Grid Infrastructure Management Repository enables such features as Cluster Health Monitor, Oracle Database QoS Management, and Rapid Home Provisioning, and provides a historical metric repository that simplifies viewing of past performance and diagnosis of issues. This capability is fully integrated into Oracle Enterprise Manager Cloud Control for seamless management. Furthermore what the doc doesn't say explicitly: The -MGMTDB has now become a single-tenant deployment having a CDB with one PDB This will allow the use of a Utility Cluster that can hold the CDB for a collection of GIMR PDBs When you've had already an Oracle 12.1.0.1 GIMR this database will be destroyed and recreated Preserving the CHM/OS data can be acchieved with OCULMON to dump it out into node view The data files associated with it will be created within the same disk group as OCR and VOTING  In a future release there may be an option offered to put in into a separate disk group Some important MOS Notes: MOS Note 1568402.1FAQ: 12c Grid Infrastructure Management Repository, states there's no supported procedure to enable Management Database once the GI stack is configured MOS Note 1589394.1How to Move GI Management Repository to Different Shared Storage(shows how to delete and recreate the MGMTDB) MOS Note 1631336.1Cannot delete Management Database (MGMTDB) in 12.1 -Mike

• Save Upgrade downtime: Upgrade APEX upfront

  - by Mike Dietrich

  With almost every patch or release upgrade of the Oracle Database a new version of Oracle Application Express (APEX) will be installed. And as APEX is part of the database installation it will be upgraded as part of the component upgrades after the ORACLE SERVER component has been successfully upgraded to the new releases. But the APEX upgrade can take a bit (several minutes or even more in some cases). Therefore it is a common advice to upgrade APEX upfront before upgrading the database as this can be done online while the database is in production (unless your databases serves just as an APEX application backend - in this case upgrading APEX upfront won't save you anything). To upgrade Oracle APEX upfront you'll have to followMOS Note:1088970.1.
