| Deyan | hello guys | 01:30 |
| grantc | hi | 01:30 |
| Deyan | grantc: in which case ingres_close() will block forever? | 01:31 |
| Deyan | any ideas? | 01:31 |
| Deyan | i have a case where ingres_close() never returns... | 01:31 |
| grantc | it should never block | 01:31 |
| grantc | unless you have an ingres_query() statement hanging due to a locking problem | 01:31 |
| Deyan | khm... | 01:33 |
| Deyan | but in that case the script should not reach the line where i call ingres_close() right? | 01:34 |
| Deyan | it should still be there where i called ingres_query() ? | 01:35 |
| grantc | yup | 01:35 |
| grantc | i would assume so at least | 01:35 |
| Deyan | me too | 01:36 |
| grantc | is it something you can reproduce on demand? | 01:36 |
| Deyan | that is why i added a simple echo before ingres_close and after | 01:36 |
| Deyan | it prints the one before | 01:36 |
| Deyan | but not after | 01:36 |
| Deyan | so it seems to me that ingres_close() blocks | 01:36 |
| grantc | CPU usage? | 01:37 |
| Deyan | no, it is not something i can reproduce easily :( | 01:38 |
| grantc | the next time it happens check to see if you have any lock waits in the server | 01:39 |
| grantc | the only thing i can think of that it might be is the clean up code going into an infinite loop | 01:40 |
| grantc | but i would expect to see excessive CPU usage | 01:40 |
| Deyan | i think you are right | 01:40 |
| Deyan | so... if there are some locks, ingres_close() blocks | 01:40 |
| Deyan | i restarted server | 01:40 |
| Deyan | and ran script again | 01:41 |
| Deyan | and now everything works | 01:41 |
| grantc | the driver performs a rollback on closure | 01:41 |
| grantc | so no locks should stop it | 01:41 |
| grantc | before that takes place each statement is closed (under duress if needed) | 01:42 |
| grantc | however under ingres_close() the function free_ii_link_result_list() iterates over the open statements and it's possible that goes into the inifinte loop | 01:43 |
| grantc | _free_ii_link_result_list() not free_ii_link_result_list() | 01:43 |
| Deyan | hold on | 01:43 |
| Deyan | i will paste 3 lines | 01:43 |
| Deyan | echo "[DEBUG] before\n"; | 01:43 |
| Deyan | ingres_close($dbcTarget); | 01:43 |
| Deyan | echo "[DEBUG] after\n"; | 01:44 |
| Deyan | the first one executes | 01:44 |
| Deyan | but second echo does not | 01:44 |
| Deyan | so i am quite sure ingres_close() does not return | 01:44 |
| Deyan | for some reasons | 01:44 |
| grantc | i have an english question or rather how would you interpret the following statement: The number is between 0 and 10 | 03:04 |
| grantc | does between imply 0 and 10 are included or not? | 03:05 |
| Deyan | good question | 03:09 |
| dyki | 10 is included 0 is not | 03:09 |
| dyki | ? | 03:10 |
| Deyan | according to my colleagues it means that 0 and 10 are included in the range | 03:10 |
| pboro | grantc, you can't know without asking :D | 03:11 |
| grantc | hmm ... where's my copy of OED when i need it | 03:11 |
| grantc | £205+VAT per year for the OED :( | 03:13 |
| grantc | i guess between could be inclusive... since a bridge between two cliffs would include the cliffs... | 03:14 |
| grantc | but the space between two people would not include the people | 03:15 |
| grantc | pboro, sorry to cause any doubts :P | 03:16 |
| pboro | ahaha :) | 03:18 |

| Deyan | check the system date | 03:20 |
| Deyan | and ingres date | 03:20 |
| Deyan | why i have that difference?? | 03:21 |
| Deyan | any ideas? | 03:21 |
| grantc | Deyan, two things - can you post any output you have to http://ingres.pastebin.com and paste the link here... | 03:21 |
| grantc | second thing your II_TIMEZONE_NAME is not set or is set to NA-PACIFIC | 03:21 |
| Deyan | i suppose that makes sense for output bigger than few lines | 03:21 |
| Deyan | thanks for timezone | 03:22 |
| grantc | you can set it to UNITED-KINGDOM or EUROPE-WESTERN to get the value you want | 03:22 |
| grantc | i kind of wish we used the Olson timezone DB | 03:23 |
| grantc | Europe/London or Europe/Madrid is so much easier to decipher | 03:23 |
| pboro | indeed | 03:23 |
| Deyan | i kind of wish ingres uses system timezone | 03:24 |
| grantc | there may be reasons you don't want to do that | 03:24 |
| grantc | internally we use GMT | 03:24 |
| grantc | but we will adjust the value at the client app | 03:24 |
| Deyan | is there some document about all these variables so i do not bother you guys here? | 03:28 |
| Deyan | i have set II_TIMEZONE_NAME to UNITED-KINGDOM | 03:29 |
| Deyan | in .bashrc of ingres user | 03:29 |
| Deyan | still no changes | 03:29 |
| Deyan | (restarted server) | 03:29 |
| grantc | what does ingprenv II_TIMEZONE_NAME say? | 03:31 |
| Deyan | still NA-PACIFIC | 03:32 |
| grantc | that's the value ingres will use on startup | 03:32 |
| grantc | ingsetenv II_TIMEZONE_NAME UNITED-KINGDOM | 03:32 |
| grantc | then restart | 03:33 |
| Deyan | will that value be persistently stored? | 03:33 |
| Deyan | thanks grantc | 03:35 |
| Deyan | very much | 03:35 |
| grantc | yup ingsetenv is persistent | 03:35 |

| grantc | perhaps we need to look at uprading subversion? | 04:00 |
| grantc | also the server is restarted 2 times a day as it is with the problems we had with trac... | 04:01 |

| *** clovisw has joined #ingres | 04:20 | |
| clovisw | hi, i'm a user of SapDB now its know as MaxDB, now its time to migrate or know another database, and i'm with a doubt, learn Postgres or Ingres? anyone can explain what Ingres is better than Postgres? | 04:22 |
| Deyan | clovisw: no idea, i am just a beginer myself | 04:28 |
| Deyan | i never liked PostgreSQL ... | 04:28 |
| Deyan | for some reasons | 04:28 |
| clovisw | you can explain that reasons? | 04:29 |
| Deyan | no idea, just a feeling | 04:29 |
| Deyan | :) | 04:29 |
| clovisw | and how about your use and learning curve of Ingres? | 04:29 |
| Deyan | however, Ingres offers some features (enterprise) that Postgres does not | 04:29 |
| Deyan | features like: OpenRoad | 04:29 |
| Deyan | ABF | 04:29 |
| Deyan | excellent VDBA (i wish i have it on Linux) | 04:30 |
| AdrianHu | The learning curve of Ingres is much lower than DB2 :D. DB2 confused the heck out of me, so I uninstalled it fairly soon after. | 04:32 |
| AdrianHu | Yeah, the terminal monitor isn't that great on Linux, but it's adequate for my role in developing bits of the backend DBMS for my PhD. | 04:36 |
| clovisw | AdrianHu, and what is your impression between Postgres x Ingres? | 04:37 |
| Deyan | grantc: ingres examples on wiki do not use ingres_commit() function | 04:40 |
| Deyan | is that a mistake, or ingres_commit() is not really necessary? | 04:40 |
| grantc | Deyan, they are based on the tests for the PHP driver which in turn don't commit as they need to be repeatable | 04:41 |
| Deyan | i am still trying to find out why ingres_close() blocks... | 04:41 |
| Deyan | it 100% blocks for some reason | 04:41 |
| grantc | 100% meaning CPU? | 04:41 |
| Deyan | nope | 04:43 |
| Deyan | cpu is fine | 04:43 |
| Deyan | load is okay | 04:43 |
| Deyan | i will paste the code... | 04:43 |
| grantc | if you want the data to persist at the end of the page you will either need to issue an ingres_commit() or enble autocommit | 04:43 |
| AdrianHu | I've used both, but neither in a real operational scenario. For me, the first things that spring to mind are that Ingres is particularly strong for distributed DBMS, replication, that sort of thing. PostgreSQL has support for user-defined data types without hacking a bunch of C code. PostgreSQL is really easy to get started with. I like the GUI. Ingres probably is too if you use it on Windows, but I have have to use Linux, though it's | 04:44 |
| AdrianHu | still not too bad. Otherwise both are capable DBMSs, good SQL Standard support (unlike MySQL!), strong support for useful things like constraints and triggers, good optimizers. | 04:44 |
| Deyan | http://ingres.pastebin.com/d5764767d | 04:45 |
| Deyan | grantc: it stops at line 63 | 04:45 |
| Deyan | when we call ingres_close() | 04:45 |
| grantc | what happens when you comment out lines 32-35= | 04:46 |
| grantc | ? | 04:46 |
| Deyan | ok, i will check that | 04:47 |
| Deyan | it will take few minutes... | 04:48 |

| grantc | Deyan, no problem, i am going to go in search of lunch | 04:50 |
| Deyan | i am using that script for migration to our new server | 04:50 |
| Deyan | originally we thought 9.4 is bugged | 04:50 |
| Deyan | grantc: yep, still the same | 04:52 |
| grantc | which version of the PHP driver are you using? | 04:52 |
| Deyan | latest one | 04:53 |
| grantc | 2.2.1? | 04:53 |
| Deyan | yes | 04:53 |
| grantc | i wonder if there is a problem with dual connections... there should not be but you never know... | 04:55 |
| grantc | i'll take a shufty after lunch | 04:55 |
| Deyan | in fact i will need 3 connections in paralllel | 04:59 |
| Deyan | 1) to the "sys" database, 2) to the project database(s) 3) to the target database | 04:59 |
| Deyan | because i want to merge all project databases into one, single database | 04:59 |
| Deyan | for legacy reasons they have been kept separate | 04:59 |
| Deyan | (old VMS ...) | 04:59 |
| Deyan | we'll talk after lunch | 05:00 |

| clovisw | ingres supports materialized views? | 05:26 |
| *** MagnusG| has joined #ingres | 05:26 | |
| pboro | clovisw, afaik no | 05:28 |
| clovisw | then to simulate that i must use triggers right? | 05:29 |
| pboro | Hmm I'm not sure if it's possible to use triggers to simulate that :/ I don't have much experience with materialized views | 05:30 |
| AdrianHu | No. Ingres does not support materialized views. There are no plans from Ingres themselves to add them any time soon. However, my research work does involve materialized views. If it goes well then there maybe a prototype in about a year's time. "Simulating" them with triggers is possible. One paper even stated that some DBMS implement them internally that way. | 05:31 |
| pboro | Here's stephenb's answer to materialized views: "Ingres does not support materialized views. This is on the to-do list but as yet has no specific release or date attached to it." | 05:32 |
| AdrianHu | You might try http://www.pgcon.org/2008/schedule/events/69.en.html It's written for PostgreSQL but should work in Ingres too. | 05:36 |
