[11:17:50 EST(-0500)] <gthompson> hi all
[11:17:52 EST(-0500)] <gthompson> in workin on a ticket for 3.2, i have run into issues getting uPortal to build
[11:17:52 EST(-0500)] <gthompson> started yesterday with an update of the trunk
[11:17:53 EST(-0500)] * EricDalquist (n=dalquist@bohemia.doit.wisc.edu) has joined ##uportal
[11:17:54 EST(-0500)] <gthompson> tried to build
[11:18:07 EST(-0500)] * mmealling (n=michael@singularity.ts.gatech.edu) has joined ##uportal
[11:18:07 EST(-0500)] <gthompson> got an error about my JDK version (1.5) not being in the range
[11:18:18 EST(-0500)] <gthompson> so after chatting with Jen
[11:18:32 EST(-0500)] <gthompson> i updated my SDK to 6 (1.6)
[11:19:05 EST(-0500)] <gthompson> i then ran an ant clean initdb
[11:19:30 EST(-0500)] <gthompson> btw: i am using the default hsql db
[11:19:44 EST(-0500)] <gthompson> the portal came up fine
[11:19:49 EST(-0500)] <gthompson> but when i tried to log in
[11:20:03 EST(-0500)] <gthompson> i got an 500 status error in the browser
[11:20:40 EST(-0500)] <gthompson> that indicated not being able find the db driver
[11:21:05 EST(-0500)] <gthompson> i chatted with Jen and tried a bunch of stuff yesterday and never could get past that error on login
[11:21:18 EST(-0500)] <athena> can you put the stack trace you got on the page in pastebin?
[11:21:19 EST(-0500)] <EricDalquist> have you run an 'ant initportal' or 'ant deploy-ear' since updating from subversion?
[11:21:28 EST(-0500)] <EricDalquist> initdb doesn't actually deploy anything to tomcat
[11:21:45 EST(-0500)] <gthompson> yes, i ran an ant deploy ear
[11:22:30 EST(-0500)] <gthompson> would the initportal be better?
[11:22:58 EST(-0500)] <athena> an "ant clean initportal" might be a good idea, just for good measure
[11:23:04 EST(-0500)] <EricDalquist> all initportal does is run deploy-ear then initdb
[11:23:05 EST(-0500)] <athena> and since you'll need the resource server updated anyway
[11:23:08 EST(-0500)] <EricDalquist> but it can't hurt
[11:23:23 EST(-0500)] <gthompson> i'll try that
[11:23:33 EST(-0500)] <gthompson> but in trying to isolate the problem
[11:23:47 EST(-0500)] <gthompson> i tried falling back to running the 3.1.1 code
[11:23:52 EST(-0500)] <gthompson> this morning
[11:24:13 EST(-0500)] <athena> i think it probably makes most sense to focus on getting 3.2 working, since you seem to be having separate problems in both instances
[11:25:52 EST(-0500)] <holdorph> i blame petro
[11:28:18 EST(-0500)] * colinclark_ (n=colin@74.198.28.32) has joined ##uportal
[11:32:34 EST(-0500)] <gthompson> sorry, had someone drop by my cube
[11:32:49 EST(-0500)] <gthompson> so just to finish the story
[11:33:10 EST(-0500)] <gthompson> i tired running a clean initdb on the 3.1.1
[11:33:13 EST(-0500)] <gthompson> and it failed
[11:33:19 EST(-0500)] <gthompson> trying to create the UP_CHANNEL
[11:33:20 EST(-0500)] <gthompson> table
[11:33:40 EST(-0500)] <gthompson> it looks like because maybe one was already in existence
[11:33:46 EST(-0500)] <EricDalquist> back in a little bit ... meeting
[11:33:49 EST(-0500)] <gthompson> i just offer that up as info
[11:33:58 EST(-0500)] <holdorph> initdb should drop all the tables as part of what it does
[11:34:08 EST(-0500)] <gthompson> so i'll try running the initportal...

[11:50:56 EST(-0500)] <gthompson> i ran ant clean initportal
[11:51:00 EST(-0500)] <gthompson> which was successful
[11:51:10 EST(-0500)] <gthompson> the portal came up
[11:51:22 EST(-0500)] <gthompson> tried to login
[11:51:29 EST(-0500)] <gthompson> and got the same error in the browser
[11:51:35 EST(-0500)] <gthompson> here's the stack trace:
[11:51:36 EST(-0500)] <gthompson> http://uportal.pastebin.com/md9ad360
[11:53:49 EST(-0500)] <athena> ok, is the error about hsql gone?
[11:53:50 EST(-0500)] <gthompson> here's the error in the browser:
[11:53:50 EST(-0500)] <gthompson> http://uportal.pastebin.com/m38544e91
[11:53:50 EST(-0500)] <athena> (sorry, eric and i are in the coop dev session)
[11:53:54 EST(-0500)] <EricDalquist> are there any errors higher up in the log?
[11:54:21 EST(-0500)] <EricDalquist> hrm
[11:54:30 EST(-0500)] <gthompson> no
[11:54:37 EST(-0500)] <EricDalquist> so cas can't find the hsqldb driver
[11:54:46 EST(-0500)] <EricDalquist> as a work around right now
[11:54:48 EST(-0500)] <EricDalquist> try: http://localhost:8080/uPortal/Login?userName=admin&amp;password=admin
[11:54:53 EST(-0500)] <EricDalquist> that bypasses cas
[11:55:07 EST(-0500)] <athena> is the hsql jar in webapps/cas/WEB-INF/lib?
[11:55:22 EST(-0500)] <athena> yeah i probably haven't actually logged in through cas in a while
[11:56:31 EST(-0500)] <gthompson> no Jen
[11:56:40 EST(-0500)] <athena> ok
[11:56:45 EST(-0500)] <athena> well at least we found the error?
[11:56:46 EST(-0500)] <gthompson> no hsql jar in cas webapp
[11:57:32 EST(-0500)] <gthompson> can i copy the one from the uportal webapp?
[11:57:48 EST(-0500)] <EricDalquist> yes
[11:58:22 EST(-0500)] <EricDalquist> sounds like a bug in trunk but just moving that jar should work
[11:58:36 EST(-0500)] <EricDalquist> re-running deploy-ear or initportal would result in you needing to do that again
[11:58:41 EST(-0500)] <EricDalquist> we'll see if we can get that fixed today
[12:03:32 EST(-0500)] <athena> thanks for the catch gthompson
[12:04:01 EST(-0500)] <athena> i usually just use the link that eric provided
[12:04:02 EST(-0500)] <athena> too lazy to click through
[12:07:09 EST(-0500)] <gthompson> hmm
[12:07:15 EST(-0500)] <gthompson> copying the hsql jar to cas
[12:07:23 EST(-0500)] <gthompson> got me past the previous error
[12:07:45 EST(-0500)] <gthompson> but the logged in view never returned
[12:08:45 EST(-0500)] <gthompson> tomcat is showing an out of memory erro
[12:08:52 EST(-0500)] <gthompson> PermGen space?
[12:12:25 EST(-0500)] <EricDalquist> ah
[12:12:27 EST(-0500)] <holdorph> have you set the permgen?
[12:12:28 EST(-0500)] <EricDalquist> yeah
[12:12:39 EST(-0500)] <gthompson> no
[12:12:45 EST(-0500)] <holdorph> http://www.unicon.net/node/1215
[12:12:59 EST(-0500)] <holdorph> search for "PermGen" on that page
[12:13:42 EST(-0500)] <holdorph> 128m is the absolute minimum for a vanilla uportal 3.1. for 3.2 trunk, it might need to be higher. not sure, haven't tried it.

[12:36:40 EST(-0500)] <athena> gthompson: is your uportal instance alive now?
[12:37:00 EST(-0500)] <gthompson> haven't gotten past the PermGen issue
[12:38:20 EST(-0500)] <athena> ok, basically you need to set an environment variable
[12:38:30 EST(-0500)] <athena> you can do that at the system level, or just for that tomcat instance
[12:38:55 EST(-0500)] <gthompson> yeah, i set it at the system level
[12:38:59 EST(-0500)] <gthompson> but still got the same error
[12:39:05 EST(-0500)] <gthompson> not sure if the change took effect
[12:39:13 EST(-0500)] <athena> probably not, then
[12:39:25 EST(-0500)] <athena> hm, trying to remember what i have my uportal permgen set to
[12:39:33 EST(-0500)] <gthompson> when it reported the error, it wouldn't properly shutdown tomcat
[12:39:45 EST(-0500)] <athena> yeah
[12:39:50 EST(-0500)] <gthompson> said i might have to forcibly shutdown the VM
[12:39:57 EST(-0500)] <athena> sometimes the shutdown scripts don't work right if it runs outof memory
[12:40:05 EST(-0500)] <athena> so you will need to kill it, then restart
[12:40:46 EST(-0500)] <gthompson> what is the proper means for killing it?
[12:41:09 EST(-0500)] <athena> holdorph or EricDalquist - do you guys have some words of wisdom on killing processes and setting tomcat JAVA_OPTS on windows?
[12:41:16 EST(-0500)] <athena> task list thingy? i'm not sure
[12:41:23 EST(-0500)] <EricDalquist> restart the command prompt after changing any setting
[12:41:25 EST(-0500)] <athena> i've forgotten how to use windows
[12:41:53 EST(-0500)] <athena> is 128 enough for permgen in trunk?
[12:42:03 EST(-0500)] <EricDalquist> I have it set to 256
[12:42:09 EST(-0500)] <EricDalquist> but I don't know what the base requirement is
[12:42:19 EST(-0500)] <athena> i think i do too
[12:42:42 EST(-0500)] <athena> let me pull up my config
[12:43:29 EST(-0500)] <athena> ok, i've current got:
[12:44:01 EST(-0500)] <holdorph> 196 would probably work for most installs
[12:44:04 EST(-0500)] <athena> -Xms=512m -Xmx768m -XX:MaxPermSize=216m
[12:44:06 EST(-0500)] <athena> yeah, probably
[12:44:11 EST(-0500)] <athena> maybe try something like
[12:44:16 EST(-0500)] <holdorph> i'm sure you could go less, but you'd want to test/tweak/test/tweak/test to find out
[12:44:23 EST(-0500)] <holdorph> for the specific environment
[12:45:25 EST(-0500)] <athena> yeah
[12:45:35 EST(-0500)] <athena> maybe something like
[12:45:50 EST(-0500)] <athena> -Xmx512m -XX:MaxPermSize=192m
[12:45:54 EST(-0500)] <athena> sound reasonable?
[12:46:10 EST(-0500)] <athena> gthompson: is this helping at all?
[12:46:56 EST(-0500)] <holdorph> i see gthompson away from his desk
[12:48:23 EST(-0500)] <athena> oh
[12:48:25 EST(-0500)] <athena> he escaped!
[12:48:38 EST(-0500)] <holdorph> i blame petro
[12:48:47 EST(-0500)] <holdorph> this time for real, he's at petro's desk.
[12:48:50 EST(-0500)] <athena> UE expert on the loose!
[12:48:52 EST(-0500)] <athena> lol
[12:49:13 EST(-0500)] <athena> tell petro to stop distracting the only person who's likely to actually fix the uportal skin (tongue)
[12:56:43 EST(-0500)] <gthompson> yeah, went for more coffee
[12:56:48 EST(-0500)] <gthompson> got waylaid by petro
[12:56:51 EST(-0500)] <gthompson> (smile)
[13:00:21 EST(-0500)] <gthompson> so i should use this:
[13:00:28 EST(-0500)] <gthompson> -Xmx512m -XX:MaxPermSize=192m
[13:00:31 EST(-0500)] <gthompson> ?
[13:01:03 EST(-0500)] <holdorph> you definitely need the permsize one. if you're cramped for memory you could try lower numbers first. but those are more reasonable if you can afford them
[13:03:16 EST(-0500)] <gthompson> bingo!
[13:03:18 EST(-0500)] <gthompson> that did it
[13:03:33 EST(-0500)] <gthompson> thanks all for the help
[13:04:01 EST(-0500)] <gthompson> now on to overhauling the ivy skin...
[13:04:53 EST(-0500)] <holdorph> and someone talk to petro about all the permgen he's using. geesh.
[13:28:58 EST(-0500)] <athena> gthompson: glad that helped (smile)
[13:29:07 EST(-0500)] <athena> so you'll probably want to comment out the page caching filter in web.xml
[13:29:20 EST(-0500)] <athena> and then once uportal is running, find the aggregation portlet and turn off aggregation
[13:30:18 EST(-0500)] <athena> we still need to find a way to turn the page caching filter off for non-aggregated resources
