IBM SPSS (22), “Serialization scheme was not recognized”
June 6, 2014
I’m being called in as IT consultant by my wife, who uses SPSS.
Today, mysteriously, it started INTERMITTENTLY failing with messages
like “Serialization scheme was not recognized” and “Could not instantiate a required server object”.
My snap answer (knowing that it has Java in it, and knowing that “serialization” is a magic word) was to suspect some sort of a Java version mismatch — but I didn’t see any evidence of a recent update at all. I go looking online, and all the advice tends to revolve around Java, but none of it has been updated (I looked inside the application’s package contents, nothing looked new there, there was no other new Java on the box). One thing that looked a little peculiar was in
~/Library/Application Support/IBM/SPSS/Statistics/22/Eclipse/configuration/nl/en_US/ . There, org.eclipse.osgi and org.eclipse.update had both been touched TODAY, “right around when the problems started”.
So WTFF Eclipse doing in my wife’s SPSS “Application Support”? She does not use Eclipse.
So I shut down SPSS (took it minutes at 100% CPU, ???) moved the IBM folder over out of the way (made sibling directory “NOT”, moved IBM and the other sibling SPSS folder into NOT) and restarted. This appears to have made things better.
