| grantc | Hi Dejan, KermitTheFragger | 01:52 |
| KermitTheFragger | can anyone tell me what the state of XA is in the JDBC driver for ingres ? | 01:54 |
| KermitTheFragger | i've googled online a bit, but can't seem to find anything concrete | 01:54 |
| grantc | there is an XA class - let me find the doc page | 01:54 |
| grantc | com.ingres.jdbc.IngresXADataSource | 01:54 |
| grantc | http://docs.ingres.com/Ingres/9.3/Connectivity%20Guide/jdbcdriverinterface.htm | 01:54 |

| *** gerhard has joined #ingres | 01:55 | |
| KermitTheFragger | grantc: g' morning! | 01:55 |
| KermitTheFragger | grantc: yeah i know XA is there, but postgres also has 'XA' support | 01:56 |
| KermitTheFragger | and that XA support is so little, that its basically useless | 01:56 |
| KermitTheFragger | so i was wondering how much is implemented in Ingres | 01:56 |
| gerhard | Morning all, what does 'XA' stand for? | 01:57 |
| KermitTheFragger | for example you can't really use postgres with JOTM or Atomikos | 01:57 |
| KermitTheFragger | gerhard: morning! Its a standard for distributed transaction management | 01:58 |
| KermitTheFragger | basically a standard for a two phase commit | 01:58 |
| KermitTheFragger | (its a little more then that, but thats what it boils down to) | 01:58 |
| grantc | gerhard, DTP via JDBC | 01:58 |
| grantc | Think tuxedo | 01:58 |
| KermitTheFragger | XA isn't a Java specific standard, JTA is the Java specific XA implementation | 01:59 |
| KermitTheFragger | nice all those acronyms ;-) | 02:01 |
| grantc | KermitTheFragger, you might be better off asking in the community forums | 02:01 |
| grantc | http://community.ingres.com/forum | 02:01 |
| KermitTheFragger | makes me feel all important :-) | 02:02 |
| Dejan | and it even gets more complicated, as there are several JTA implementations | 02:02 |
| Dejan | :D | 02:02 |
| Dejan | JTA is more like JAVA-related specification | 02:02 |
| * grantc is glad he does not do much with java | 02:03 | |
| KermitTheFragger | yeah true, i put it all wrong there, JTA is indeed the Java interface for XA | 02:04 |
| KermitTheFragger | Atomikos, JOTM, etc are the implementations | 02:06 |
| KermitTheFragger | grantc: ok ill try that! | 02:06 |
| grantc | the people that work on JDBC are all US based so you might have to wait a bit to get an answer unless there is someone from one of the EU offices that knows the answer | 02:06 |
| KermitTheFragger | is XA really that uncommon ? I thought most Java people loved elaborate standards :-) | 02:06 |
| gerhard | Thanks for the information | 02:07 |
| Dejan | KermitTheFragger: i am not much of Java lover too, even though i do java more than anything else these days | 02:09 |
| Dejan | from what i see - java developers care more about what SUN says more than anything else | 02:09 |
| Dejan | so JTA is what they know about | 02:09 |
| Dejan | and what matters | 02:09 |
| KermitTheFragger | grantc: whats your poison then ? :) | 02:09 |
| Dejan | they do not care about XA that much | 02:09 |
| grantc | ruby and php | 02:09 |
| gerhard | Indeed, there are lots of abbreviations around (-: | 02:09 |
| Dejan | yeah | 02:09 |
| grantc | and a bit of python when needed | 02:09 |
| Dejan | and lots of hype | 02:09 |
| Dejan | an example is BLOG | 02:09 |
| Dejan | BLOG is a replacement term for something that existed for decades - JOURNAL | 02:10 |
| gerhard | my all time favorite.... | 02:10 |
| Dejan | or you can even call it a DIARY | 02:10 |
| gerhard | PCMCIA | 02:10 |
| Dejan | some smart ass just decided to call it BLOG | 02:10 |
| Dejan | and term-freaks adopted it | 02:10 |
| Dejan | :) | 02:10 |
| gerhard | = people can't memorize computer industry's acronyms (-: | 02:11 |
| Dejan | yeah, it gets crazier and crazier | 02:11 |
| Dejan | :D | 02:12 |

| *** pboro has joined #ingres | 02:13 | |
| KermitTheFragger | Dejan: well i dont listen much to sun :) | 02:13 |
| KermitTheFragger | I mostly use Spring and OSGi | 02:13 |
| KermitTheFragger | and JDO | 02:13 |
| KermitTheFragger | which is done by Apache | 02:13 |
| Dejan | I can bet my right hand that 50% of Java developers do not know what XA is | 02:13 |
| Dejan | more precisely X/Open XA | 02:13 |
| KermitTheFragger | thats probably more because there are not many people who need distributed transactions :) | 02:14 |
| Dejan | but ALL Java developers know what JTA is | 02:14 |
| Dejan | ok, not all, but most | 02:14 |
| KermitTheFragger | there is no alternative for XA in JTA | 02:14 |
| Dejan | JDO is not done by Apache, i think | 02:14 |
| Dejan | it has been donated to Apache ? | 02:14 |
| KermitTheFragger | but JTA are just the XA interfaces in Java | 02:14 |
| KermitTheFragger | definitly | 02:14 |
| KermitTheFragger | http://db.apache.org/jdo/ | 02:14 |
| Dejan | i always thought it was, like Derby, donated to the Apache foundation | 02:15 |
| KermitTheFragger | Sun donated it when they decided to go for JPA | 02:15 |
| Dejan | by IBM | 02:15 |
| Dejan | or SUN yeah | 02:15 |
| Dejan | did not know which one | 02:15 |
| Dejan | Derby was made by IBM i think | 02:16 |
| KermitTheFragger | yes derby was IBM | 02:16 |
| Dejan | used it only once though... | 02:16 |
| Dejan | because i had to | 02:16 |
| Dejan | :D | 02:16 |
| KermitTheFragger | :) | 02:16 |
| KermitTheFragger | well its nice for embedding | 02:17 |
| KermitTheFragger | i use it for an GUI application which needs to do online and offline stuff | 02:17 |
| Dejan | i would rather embed SQLite :D | 02:17 |
| KermitTheFragger | well there is a big difference between SQLite and derby, SQLite is, well errrr Lite ;-) | 02:18 |
| Dejan | yep | 02:18 |
| KermitTheFragger | were as derby supports full SQL, the works, even XA to some degree | 02:18 |
| KermitTheFragger | as with all, it depends on what you need :) | 02:19 |
| KermitTheFragger | but in all i think derby is nice | 02:19 |

| KermitTheFragger | with datanucleus (JDO), atomikos(JTA) and Ingres | 02:30 |
| grantc | if you want to look at the source for the XA code take a look at http://code.ingres.com/browse/wsvn/ingres/main/src/common/jdbc/java/jdbcx/ | 02:30 |
| grantc | to check out, with SVN, use the URL http://code.ingres.com/ingres/main/src/common/jdbc/java/jdbcx/ | 02:30 |
| KermitTheFragger | grantc: nice, thanks | 02:30 |
| grantc | no problem | 02:31 |
| KermitTheFragger | im going to need those since i see the standard jdbc driver is optimized, not giving line numbers at stacktraces | 02:31 |

| pboro | any java + ingres users around with 9.2? i need someone to verify that my test case reproduces :) | 05:03 |
| KermitTheFragger | pboro: im a java + ingres user, but im using 9.3 | 05:05 |
| KermitTheFragger | and im a ingres noob :) | 05:06 |
| KermitTheFragger | i only started using it yesterday :) | 05:06 |
| pboro | hmm 9.3 might have to bug too | 05:07 |
| KermitTheFragger | what bug ? | 05:07 |
| pboro | I have a dump of a small table and a small java program, which during execution, throws an exception because of an error in the dbms | 05:07 |
| pboro | it's a concurrency bug in querying long varchars simultaneously | 05:07 |
| pboro | (my java program spawns two threads and runs the one and same query in both, resulting in error in ingres for at least me) | 05:08 |
| KermitTheFragger | concurrency bugs are often hard to reproduce | 05:08 |
| KermitTheFragger | on different systems | 05:08 |
| pboro | I have been able to reproduce this on both Linux and Solaris | 05:08 |
| pboro | Haven't tried Windows yet, tho' :) | 05:09 |
| KermitTheFragger | what kind of error does ingres throw | 05:09 |
| pboro | lemme post it in pastebin | 05:09 |
| pboro | http://pastebin.com/m3aa9660c | 05:09 |
| KermitTheFragger | pboro: weird, and running the queries serialized does not produce the problem ? | 05:15 |
| pboro | yup, or if I replace the LONG VARCHAR column with VARCHAR | 05:16 |
| KermitTheFragger | well i guess you can then just file a bug report | 05:17 |
| pboro | I did :) but they could not reproduce it (at least not yet), so I started to suspect myself :D | 05:17 |

| PaulM05 | IIRC someone on the forums was trying to compile with 3.0 and hit problems. 2.x and you can usually make it work, it's just fiddling with build config to get it to see the right libraries | 07:22 |

| George | Hi when I build the Ingres on my Ubuntu, I have /src/cl/clf/handy_unix_win/cldio.c:1685:26: error: linux/falloc.h: No such file or directory | 07:42 |
| George | anyone has idea why this happened? | 07:43 |
| DarylM | Not sure. My Linux system has a /usr/include/linux/falloc.h | 07:43 |
| grantc | i've not built ingres on ubuntu (9.10) in the last month or so but it did build | 07:44 |
| DarylM | George: Do you have an falloc.h in /usr/include ? | 07:44 |
| grantc | not that it helps... i'll update my build area | 07:44 |
| George | checking... | 07:45 |
| atrofast | Yeah Ingres does not build against Xerces 3.0, I tried that | 07:45 |
| atrofast | It does work fine against 2.8 though | 07:45 |
| George | odd, i don't have that header in my /user/include | 07:46 |
| George | /usr/include | 07:46 |
| DarylM | Ingres does build against X 3.0 | 07:46 |
| DarylM | You just need our changes for it :-) | 07:46 |
| George | ok | 07:46 |
| DarylM | I am pretty sure the latest SVN repository files support Xerc3.0 | 07:47 |
| atrofast | Oh okay, I tried it a week and a half ago and it didn't work but if it's been fixed, that would be great | 07:49 |
| DarylM | You will see code supporting Xerces 3.0 like this: | 07:50 |
| DarylM | front/misc/impxml/SAXImportHandlers.hpp:# if XERCES_VERSION_MAJOR > 2 | 07:50 |
| DarylM | There are some fixes to Jam build information also | 07:50 |
| DarylM | because the Xerces folks made a gratuitous change to the library file name | 07:50 |
| DarylM | (sigh) | 07:50 |
| PaulM05 | looks like falloc.h is in linux-libc-dev | 07:51 |
| atrofast | Okay yeah If I grep SVN head it has a few lines wit hthat in them | 07:52 |
| atrofast | Why doesn't Ingres figure out your version properly though? I have 2.8 installed but it always tries to look for 2.7 | 07:53 |
| atrofast | Is there any fix for that in main yet? | 07:53 |
| atrofast | Also even if I set XERCVERS BEFORe I source bldenv, bldenv clobbers it and I have to set it after | 07:54 |
| grantc | atrofast - running set_env.sh then setting XERCVERS works fine | 07:55 |
| atrofast | Doesn't help if you use runbuild.sh though | 07:56 |
| George | maybe I did something wrong in my installation, ereq.h, erfe.h are missing too | 08:00 |
