What was causing this??

Is there any transactions happening in these DBs or not??

Any patching on server or DB that prevents the data transfer??

Why DP doesn't err anything??

No idea until we checked the seaudit log. The inet service was restarted from an local admin account, from then onwards the DP processes were lacking the root access rights which prevented from reading the data.

Solution:

Once again the inet daemon was restarted from root.

Commands to restart the DP inet service from Linux client:

#/etc/init.d/omni stop

#/etc/init.d/omni start
