Hi,
I haven't used rmid myself, so I'm certainly no expert on what
might go wrong with it.
But looking at the tool docs, it appears a security policy file
might be required. See the page at
http://java.sun/com/j2se/1.3/docs/tooldocs/solaris/rmid.html
Although the doc refers to Solaris, we're using exactly the
same implementation of rmid for MPE/iX.
You might also turn on a debug switch that's in the code to see
if it gives any additional information about the failure:
rmid -J-Dsun.rmi.log.debug="true"
There should be a 'log' subdirectory created when you run
rmid, is it being created, and does it have any files in it?
The IOException may indicate inability to create a directory
or to create files in it.
If none of these help, send me any additional stack traces
that you get (if any are different than the one shown). A
'System call error' usually indicates a POSIX call within
the JVM failed, and it may be something that needs a fix
within the VM itself if the above suggestions don't get
around it.

: We are implementing a system using Java to communicate between our HP3000 969 and an NT server to send data back & forth. I downloaded the latest version of Java in December 2000, and it was running happily in testing (well, other than 1 show-stopper, but that's another story). We then put up a firewall and locked down the ports being used, with the result that the 2 Java agents on the 2 boxes could not talk to each other, which resulted in the software being rewritten.
: Now, I know virtually nothing about Java, so I'm no real help. The software now uses "rmid", an RMI daemon to register services being used (??). However, when I run rmid, it dies with the following:
: shell/iX : rmid
: Activation.main: an exception occurred: exception while taking snapshot; nested exception is:
: java.io.IOException: System call error
: sun.rmi.log.LogException: exception while taking snapshot; nested exception is:
: java.io.IOException: System call error
: at sun.rmi.log.ReliableLog.<init>(ReliableLog.java:116)
: at sun.rmi.log.ReliableLog.<init>(ReliableLog.java:135)
: at sun.rmi.server.Activation.main(Compiled Code)
: The developer knows Java but nothing of the HP3000, so he's of little use.
: I know nothing of Java, so I'm of no use.
: Can anyone out there please shed a little light on this? Things to check? Switches to push or pull???
: TIA,
: Greg.
