In the zope application that I am working on, there are nearly 40 ZEO clients. Restarting 40 ZEO clients is a time consuming process which takes hours - especially the creation of .zec files in each of the ZEO clients takes a lot of time.

Those files are on-disk caches of object state recently loaded from the ZEO server. What takes the time isn't *creating* those files (they are created empty if they don't already existt), but rather verifying the contents of the existing ones. Remove them will speed the restart process enormously: they will then be repopulated as each client fetches data from the storage. Turning off the 'client' option in the '<zeoclient>' section of your zope.conf disables the "persistent" cache, which means that each appserver creates the cache as a (hidden) tempfile, removed automatically at shutdown.

My doubt is whether it is possible to use one .zec file shared among all the ZEO clients?

No, that is not possible.
