Experiences with Vista and Oracle software (2)

A few months ago I wrote this blog about installing (Oracle) software on my new Vista laptop. I already installed these components several times on Windows XP, so I thought it would be a walk in the park. In the end, it took me a couple of days instead of hours … :-(
There are lots of threads on the OTN forums -like this one- dealing with Vista. It turned out I wasn’t the only one struggling with it.

This blog is about installing Oracle SOA Suite and patch on Vista. Common errors thrown at me -some gave me nightmares :-) - were:

  • OWSM configuration assitant fails.
  • Error: Missing ormi[s]://host:port.
  • This OC4J is configured to make JMX connections via RMIS and fall back to RMI if the RMIS port is not configured. The RMIS connection on the OC4J instance null on Application Server null is configured but a connection could not be established. The JMX protocol is specified by the oracle.oc4j.jmx.internal.connection.protocol property in opmn.xml.

I did three “batches” of steps to get it running:

  • Perform the pre-installation steps as documented in the Oracle SOA Suite and installation guides. These contain the usual steps like configuring a loopback adapter, not using whitespace characters in directory names, having the right JDK, etc. These guides are bundled with the SOA Suite installation files when downloaded from OTN. Performing these steps is “business as usual”. However, these steps alone didn’t work.
  • Perform some steps as documented in Metalink note 444112.1.
  • Browse through the OTN forums for the remaining errors and stacktraces.

These last two “batches” consist of the following additional actions:

  • Do not use underscores in your computer name. I had an underscore in it -love them since you can’t safely use whitespaces :-) - and I couldn’t run SOA Suite. See this forum post.
  • IPV6 is not supported with Vista. There are some compatibility issues between Sun’s JDK and the new IPv6 protocol. I explicitly disabled IPv6 by removing “::1 localhost” from my hosts file, disabling Internet Protocol version 6 (TCP/IPv6) for all my network adapters in the Windows network configuration, and added the following registry value (DWORD type) set to 0xFF:
    HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Services, Tcpip6, Parameters, DisabledComponents. This is documented in the Metalink note. You can also add the Java option “” to use IPv4 instead of IPv6.
  • Install, start, and stop Oracle SOA Suite as administrator (e.g. right-click and choose “Run as administrator”). Somehow this causes the relative paths in the Start Menu shortcuts to not resolve to the correct locations anymore. I changed these locations to absolute file paths. To do this, edit the [SOA Suite home]/bin/runstartupconsole.bat file and change the line containing “set ORACLE_HOME”.
  • Firewalls and virus scanners are great when they are not hogging your system and/or block wanted messages. The latter happened on my laptop. I disabled the pre-installed security software since it blocked certain requests and replies from and to my local Oracle SOA Suite.
  • I did an advanced install and used Oracle 10g XE as dehydration store since the pre-installed Oracle Lite database (Oracle SOA Suite basic install) crashed every now and then.

These errors can be really frustrating. Especially when you successfully install the exact same software on another OS within the hour and all your “Linux” and “XP” colleagues have Hello World running on Oracle SOA Suite :-) Hope this helps.

Vote for sessions at Oracle OpenWorld 2008 (2)

Lonneke Dikmans already blogged about the possibility to submit and nominate sessions for Oracle OpenWorld 2008. This is one of the ways to get involved in the Oracle community through Oracle Mix.

I submitted an idea called "Putting SOA to Use". This session is based on experiences from a customer-case in which a Service-Oriented Architecture is implemented using Oracle technology such as BPEL, ESB and WebCenter. Read it and if you think it’s interesting vote for it!
