GP installer fails to launch, Java throws exception:

Launching installer...

An internal LaunchAnywhere application error has occured and this application cannot proceed. (LAX)

After some googling around, I discovered that Launch Anywhere often screws around with PS1, so changing this for the current shell resolves the issue:

$ export PS1=">"

Some basic ways to access GP's HSQLDB:

You must have RC configuration file(s) in the home directory either sqltool.rc or dbmanager.rc:

# This is for a hsqldb Server running with default settings on your local
# computer (and for which you have not changed the password for "SA").
urlid gp
url jdbc:hsqldb:hsql://127.0.0.1:9001/xdb
username sa
password

Then sqltool (commandline) or DatabaseManager (GUI) can be called:

java -cp hsqldb.jar org.hsqldb.util.DatabaseManager --urlid gp

If GP is installed on NFS share, it fails to start due to the HSQLDB failure.

This is NOT GP's issue. It's a HSQLDB issue. The workaround is disble HSQLDB file locking by presenting these in DB's properties file:

pwbcad@ubuntu:data$ cat db0.properties
hsqldb.nio_data_file=false
hsqldb.lock_file=false
...

UPDATE: the above method is for version between 1.7.2. and 1.8.0. Couldn't find out which version the GP uses. But tried replace the hsqldb.jar with the 1.8.10 version, now GP can start successfully.

When running "qstat-f" on exec host, it complains:

error: commlib error: got select error (No route to host)
error: unable to contact qmaster using port 6444 on host "pwbclinuxlab.garvan.unsw.edu.au"

pwbclinuxlab.garvan.unsw.edu.au is the ex-qmaster which has been removed. Even in the new qmaster, add the exec host again, the exec host still remember the old one. Because it's the string hardcoded in:

/var/lib/gridengine/default/common/act_qmaster

When running "qstat-f" on exec host, it has another complain...

error: commlib error: access denied (client IP resolved to host name "". This is not identical to clients host name "")
error: unable to contact qmaster using port 6444 on host "sgeqmast01.garvan.unsw.edu.au"

Read Things to think about before installing Grid Engine.

This is very likely related to DNS. SGE requires both forward and reverse DNS queries. So make sure DNS server has been setup properly. In case of DNS server setup is too difficult, adding proper entries to /etc/hosts will fix the issue.

Remember: qmaster's hosts file must contain all SGE hosts' (qsub host, qexec host etc) record. Any other SGE host must contain qmaster's record.

127.0.0.1       localhost
129.94.136.232  sgeqexec01.garvan.unsw.edu.au   sgeqexec01
129.94.136.230  sgeqmast01.garvan.unsw.edu.au   sgeqmast01

Ubuntu 10.10 Base Image Installation Note

On the new VMware platform, I need to create a Ubuntu base image, which will be used as a deployment template for other groups. The base image has to be basic, flexible and secure.

Partioning the virtual hard disk, 36GB, LVM is used.

I create a volume group called VG01 on the 36GB HDD. From there I use the follow partion schema. There is no dedicated partition for /home because the users store the data to NFS space.

• 210MB /boot ext3
• 15.1GB / ext4
• rest swap

Partitioning Strategies

Enable OpenSSH

Just remember to select it during the installation.

Build up the min security FIRST

First modify the entries in the following files:

root@pwbclinuxlab:~# cat /etc/hosts.allow
# /etc/hosts.allow: list of hosts that are allowed to access the system.
#                   See the manual pages hosts_access(5) and hosts_options(5).
#
# Example:    ALL: LOCAL @some_netgroup
#             ALL: .foobar.edu EXCEPT terminalserver.foobar.edu
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.
#

#Allow servers & admin
...
root@pwbclinuxlab:~# cat /etc/hosts.deny
# /etc/hosts.deny: list of hosts that are _not_ allowed to access the system.
#                  See the manual pages hosts_access(5) and hosts_options(5).
#
# Example:    ALL: some.host.name, .some.domain
#             ALL EXCEPT in.fingerd: other.host.name, .other.domain
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.
#
# The PARANOID wildcard matches any host whose name does not match its
# address.
#
# You may wish to enable this to ensure any programs that don't
# validate looked up hostnames still leave understandable logs. In past
# versions of Debian this has been the default.
# ALL: PARANOID
ALL: ALL

Optional: change root password

sudo passwd

Optional: enable RSA SSH login

X11, Xming Confusion: Which X Server is Serving You?!

When I tried to start qmon, a X11 application from SGE, it gave my errors:

Warning: Cannot convert string "-adobe-helvetica-medium-r-*--14-*-*-*-p-*-*-*" to type FontStruct

X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  45 (X_OpenFont)
  Serial number of failed request:  343
  Current serial number in output stream:  354

According to many posts like this one, suggest to add required fonts from the repository then add to X11 path. Makes perfect sense. But I stuck in the step that adding fonts to X11 path by using xset fp+:

unused@pwbclinuxlab:~$ xset fp+ /usr/share/fonts/X11/100dpi
xset:  bad font path element (#90), possible causes are:
    Directory does not exist or has wrong permissions
    Directory missing fonts.dir
    Incorrect font server address or syntax

I tried many ways to fix it, like permissions, created fonts.dir by using mkfontdir (See here). Nothing helps. I had to try to find X11's conf file to see if anything there, but I couldn't find any!!! I checked X11 directories under /etc, /usr all empty or no binary there!! Now I realized that there is no X11 server running.

I almost forgot, I use PuTTY in a Windows platform, with Xming running, and now I am almost sure, Xming is the X server I need to modify, not the one on the server!! I found the font support installation from sourceforge called Xming-fonts-7-5-0-25-setup.exe, installed it, everything is fine!!

Password-less SSH via PuTTY

I need to connect to a Ubuntu 10.10 server via PuTTY, password-lessly.

You can generate the key pair from two places:

• On the Unbuntu server by using ssh-keygen. Detail
• On the local machine, using a utility called PuTTYgen

But using either way alone won't work because:

1. PuTTY only understands the private key file generated by PuTTYgen. PuTTY complains if I select a private key generated by ssh-keygen (on the server).
2. Ubuntu OpenSSH doesn't understand the public key generated by PuTTYgen. The server will give you Server refused our key if I copy the public key generated by PuTTYgen.

The solution is tricky but simple: all I need to do is, generate the key pair on the server by using ssh-keygen. Copy the generated private key to local machine, and load it to PuTTYgen, then convert it into PuTTY format. That's all!
