after update to AliEn version v2.3 all tests above succeed.

can we get jobs ?

AliEn Job agents arrive, but do not startup
- Jobs are sent to queue "alice".
- via xlsmon check status of batch farm machines
- via xlsbatch check what hosts belong to alice queue. These are HOSTS: lxb006 lxb007 lxb008 lxb009

ergo lsrun -m lxb007 ls /tmp/u/aliprod/logs

PS:

Read file <cp.err> for stderr output of this job.

remark: copy via rcp demands lots of requirements:
- rlogind has to run on remote machine
- /etc/hosts.equiv has to contain line "+ username"
- on the target machine in $HOME(user) .rhosts has to exist containing "source username"
- then you are supposed to be able to copy via:

    rcp filename targetpc:/some/directory (put file)
    rcp remotepc:/some/path/filename /local/path (get file)

redirect logfile

for easier debugging central logfile is moved to a position which is accessible from both CE and WNs. Therefore Change in Central LDAP: aliendb5.cern.ch, port 8389

entry: dn:ou=GSI,ou=Sites,o=alice,dc=cern,dc=ch
value: logdir: /tmp/u/aliprod/logs
       to      /d/alice01/aliprod/logs

and restart services

alien Stop/Start Monitor
alien Stop/Start CE
alien Stop/Start SE (kill xrootd manually)
alien Stop/Start MonaLisa
alien Stop/Start PackMan

update to AliEn 2.4

after update to AliEn version v2.4 all tests above succeed.

problem with double domain still there.

Next fix:

cd
cvs -d :pserver:anonymous@jra1mw.cvs.cern.ch:/cvs/jra1mw 
co  -r glite-alien-common_branch_2_0_0 org.glite.alien.common
cd org.glite.alien.common/src
autoconf

result:

Use of uninitialized value in concatenation (.) or string at /u/aliprod/alien2/share/autoconf/Autom4te/XFile.pm line 229.

now do:

cd /tmp
wget http://pcalildap.cern.ch:8888/i686-pc-linux-gnu/HEAD/
download/alien-common-2.2.5_i686-pc-linux-gnu.tar.bz2
cd $HOME/alien2
tar jxvf /tmp/alien-common-2.2.5_i686-pc-linux-gnu.tar.bz2

ok, double domain is gone

new problem: AliEn does not understand the correct amount of job slots at GSI. Result: uncountable job agents are being submitted until the queue is blocked.

solution:

comment the lines 104 and 106 of
/u/aliprod/alien2/lib/perl5/site_perl/5.8.7/AliEn/LQ.pm

#    if ($_ =~ /(alien)|(agent.startup)/i) {
      push @queueids,$1;
#    }

then try again:

alien login --exec status

problem

3 AliRoot jobs per WN too much.

solution

Try to reduce to 2 jobs per WN

update to AliEn 2.5

same procedure as above with

Default workspace location = /u/aliprod/.alien/cache
Installation location = /u/aliprod/alien2

to be installed is

client, gshell, root, site, lcg, monitor

after successful installation the installer asks:

terminal time=xterm ???(unknown terminal type)

but this can also be cancelled. AliEn2 works nevertheless.

update to AliEn 2.6

see above, but when starting

./alien-installer

not the installer-GUI pops up, but instead:
