Migrate profiles for the proxy server

 

Procedure

To migrate from a V6.0.2 profile with the proxy server feature to a V7.0 profile.

1. Make a copy of all the required V6.0.2 files...

   cd install_root/bin
   ./WASPreUpgrade.sh

   Point it to the V6.0.2 release.

   We can delete these V6.0.2 files, but this action is not recommended.

2. Create corresponding profiles in V7.0.

3. Run WASPostUpgrade...

   cd install_root/bin
   ./WASPostUpgrade.sh

   Point the commands to the WASPreUpgrade backup directory created in step one.

 

HP-UX Gotcha

Note that if we run the WASPreUpgrade.sh command from an IBM WAS V7.0 CD-ROM on the HP-UX operating system, the command might fail unpredictably and hang indefinitely.

The ncdnode setting for the operating system, which specifies the maximum number of CD-ROM file-system nodes that can be in memory at any given time, has a default value of 150. This value might not be large enough to run the WASPreUpgrade.sh command if other files are open on the CD-ROM.

If the WASPreUpgrade.sh command fails and hangs, running the ls -l command in the directory that contains the Java binary on the CD-ROM might fail with an error similar to...

/cdrom_ee/hpux_parisc_suppl2/JDK/jre.pak/repository/package.java.jre/java/jre/bin/PA_RISC2.0/: File table overflow

To resolve the problem, before you run the WASPreUpgrade.sh command, increase the number of nodes that can be allocated from a CD-ROM to 1000:

kctune ncdnode=1000
