Monitoring Oracle Dataguard Status

Received a tip from the gurus:
v$dataguard_stats - various stats, including apply lag.
v$dataguard_status - status messages related to dataguard.
v$managed_standby - info on the standby 

v$archive_gap - shows the # of archived redo logs the standby is
behind.  Since we're shipping in real-time, this should nearly always be 0.

Setting a Sphinx theme

To set a theme in Sphinx:

  • find a theme you want to copy.  It will generally be a directory full of files.
  • copy the directory under your project's _templates directory.
  • set the html_theme in conf.py
  • some docs mention setting html_theme_path as well, but it doesn't seem necessary if it's under _templates.
  • There's some nice themes at https://readthedocs.org

$ ls _templates/

$ diff conf.py-orig conf.py
< html_theme = 'alabaster'
> html_theme = "sphinx_rtd_theme"
> html_theme_path = ["_themes", ]    ### probably not necessary

"git push" to Github wants me to log in!

If git prompts you for a username when you push:

$ git push


Check your remote settings.

$ git remote -v
origin https://github.com/YOURNAME/notebook.git (fetch)
origin https://github.com/YOURNAME/notebook.git (push)

If it's an https reference, you can change it to an ssh reference as follows. 

$ git remote set-url origin git@github.com:YOURNAME/notebook.git

And everything is great!

$ git push
Everything up-to-date
