Hello I'm Bob Aiello, author of Configuration Management Best Practices and member of the
GoMidjets family
GoMidjets is an expert Rational ClearCase administration
providing award-winning plugins and add-ons
I'd like to discuss the touchy issue of potential failures and Rational
ClearCase
and their implications for your organization
After i tell you the bad news
also just the way to avoid such problems
and keep ClearCase alive and kicking so don't get scared
and wait until the end
As human beings we're all optimise
weekend underestimate risk
but as managers we must take into account in consideration the bad things
can happen
researched by security and risk management experts at symantec
showed that organizations on average
tend to underestimate the risk of down time
by fifty percent or more
this means that the technical experts who should know better
underestimated the actual downtime by af
take this into account when you ask me respect your organization
the pot of money institute
estimate the cost of incidents to be over
five thousand dollars per minute
that's a lot of cash
it organizations
that depend upon rational clearcase per source code management
as many as one out of the four downtime incidents
may be due to repository corruption
cited in the symantec report
this is a critical problems
and splashing clearcase
is a repository of choice for storing source code
configuration files and other artifacts essential for running your business
information stored in the clerk is database
represents a lot of hard work
and investment
naturally it should be protected
there are many reasons why systems failed
clearcase is robust and complex system
that has many environmental dependencies
for example
an electrical outage could result in the loss of data affecting a specific
version open element
while not immediately apparent
while corruption can grow over time
until one day
clearcase just stops working
based gold midgets experience in fixing clearcase failures
it takes at least today
and sometimes more to get the system
fully functioning again
he can take
just powers
isolate the cause of the failure
and identify the clear case is the root of the problem
then the clearcase repository needs to be fixed
or else you sort from a back up
if the clearcase repositories corrupted
it can take hours or even days to repair
this means that developers may lose access to the source code repository
causing development schedules to also be delayed
which obviously keep impact the deadline
developers need reliable and uninterrupted access to the source code
will posits worry
across the preventing repository corruption is very low
fixing a problem immediately after the kurds is also a relatively inexpensive
having your entire team lose access to the source code repository
can be very expensive in many different ways
certainly
you'll need to be concerned about the health of the clearcase repository
but as promised well also present a solution to ensure
that you can proactively monitor the integrity
appearance higher clearcase imparted
i_b_m_ recommends that produce administrators
perform preventive maintenance which simply needs
checking your system regularly
that helps prevent many serious problems
since almost all block repository problems
or by the you issue corrupted files
you can prevent major problems by taking care of the small ones as they happen
i_b_m_ recommends that organizations checked their plea occasion barman
frequently
to ensure database integrity
if you check clearcase everyday then you can ensure you have a healthy system
that keeps on working
it's easy for i_b_m_ to recommend that you run checks every day
but the tool provided for doing this or not always that easy to use
there are many checks to run
and each has its own nuances intricacies
even for expert clearcase administrators this effort can take one or more hours
to complete
that they have sound like a month much but
multiply that by www every single working day you get a lot of time
devoted to make its
what usually happens is that now you will checks
are rarely performed
many organizations develop scripts have performed at least some of the checks
automatically
this is a excellent approach but often not enough
the reason is that there are many different things that can go along with
clearcase
writing a robust utility
requires considerable experience
even if you're a clear case expert maintaining the scripts can be a
time-consuming and expensive endeavor
echo midgets
we create solutions that the dress all of these problems
for example clear check isn't diagnostic tool that supports rational clearcase
clerkship provides a comprehensive report
which summarizes the state of the system
and gives administrators full details
on any existing or potential problems
at the heart of clear checked
here's an extensive database that collects information
on what can go along with clear case and what you can do about it
the knowledge base
includes the clearcase administration best practices
and kill automatically check for problems so that we have seen occur from
time to time
obviously these are all best practices that are recommended but not him
except our menu driven interbase reduces complexity
and saves you a lot of time
another important feature of the databases that we also collects
proactive solutions
as you will see him we delve into the reports
we provide advice on how to handle
every issue that clear check finds
this advice helps administrators quickly resolved
and remedy clearcase issues
without spending a lot of hartman african research and solutions
we update the knowledge base on an ongoing basis
to make sure that all our customers enjoy
the most up to date features and protection
let's take a closer look at the critter check with port
the first item
is a summary
so the radar can see in a glance how healthy or not the clearcase repository
is
then it was all the checks that were warm with results
the green check mark
indicates that this specific check
returned a valid results
yellow caution mark indicates that there's an issue with the check
it's not necessarily problem now but it may grow into one
and should be taken care of
finally
the red stop sign says
here's trouble
this is a major problem and report not only finds the problems but are also
suggest solutions
with a link to related
i_b_m_ documentation
echo midgets we believe that solutions must be use evening news that they are
to be useful at all
sore approach in developing clear check
west created as a clear case plugin
that is usually added onto the existing system
clear check is installed very quickly
using in is you don't understand
next next
finish scream
clear check automatically identifies that different databases
so configuration is easy
once installed
they can generate a report
every day and send it in several formats

problem solutions

of our products
including i'd keep its practices in interpreting reject
with the existing systems
to get just one example
we provide chill options for integrating checks daily backups
based on two backup methods
that are considered industry standards
another important thing we did when we just started out
was to get our software tested by i_b_m_
and approved for rational
this means that i can confirm secretary will work
with any clearcase installation without a hitch
we are continuing to work with i_b_m_ to word from their experience
and prove our product you ensure clear check users get the best possible
service
you can think of clear check isn't anti-virus service that constantly
monitors the system
analysts the administrator kit any sign of something about will
this was the preventive maintenance approach
based on the fact that he's era cheaper effects more problems
