I issue the nova manage db sync command and when i issue I'm facing the problem,
TRACE nova File "/usr/lib/python2.7/dist-packages/sqlalchemy/engine/url.py", line 56, in __init__
2015-01-11 00:31:29 TRACE nova self.port = int(port)
2015-01-11 00:31:29 TRACE nova ValueError: invalid literal for int() with base 10: ''
Can you suggest the solutions.
