Syncsort Process - SEM Wait State
A Warehouse system, running for many years started encountering delays in large sorts. On one Sort of a 10GB file with 18 million lines - it used to take only less than 1 hour to perform. But in the last few, it's been taking 4+ hours.
Observation in glance shows the Syncsort process is waitig on SEM.
Any clues as to what can be done to recifty this issues? Server has been static with patches, configuration for many years now and we've no I/O issues at all.
Also, the end process of the job which does a "wc -l" takes much longer to perform with CACHE waits.
TIA!

Hi Alzhy:
This would appear to be a continuation of your earlier thread:
http://h30499.www3.hp.com/t5/System-Administration/HP-UX-11-11-wc-l-on-a-BIG-ASCII-File-is-slow-and-is-in-quot/m-p/4753730#M388452
...which should bear mention.
Regards!

HP insists a "Change" happened and I am still trying to find out.

Re: Syncsort Process - SEM Wait State
Have you considered the possibility that the input data have experienced a slight change of content (language or character type, field definition, length, etc)?
