Elements of the Enterprise CC Environment

• Parallel Development

• Multiple supported releases and features

• Rapidly changing development strategies

• Support concerns can limit software tool options

• Source control tools cannot impede development

Some Ideas on Best Practices

• Repeatability, both from a procedural and organizational standpoint

• “No such thing as a silver bullet.”

• Automation should center on– Simplifying developer’s jobs without

sacrificing administrative control & flexibility– Making software development more visible– Reducing admin time spent on common tasks

Simplifying User Administration

• A config spec generator can replace some features of UCM– Keeps config spec in a group-readable, admin-writable

directory

– Automatically creates development branches in the VOBs

– Automatically creates config spec based on branching scheme

Simplifying User Administration

• A wrapper for mkview– NIS host map entries for vws_<username>,

pointing to view server (either central server or user’s workstation)

– mkview script creates view in a view_storage directory on vws_<username>.

– Easy to modify view server parameters (location, cache, etc.)

Watching MultiSite

• Script monitors the size of the incoming and outgoing shipping directories.

• Notified daily if there are failed packet deliveries

Homebrew Product Integration• ClearQuest 2001 / ClearCase 4.1 integration is

nice, but slow• To avoid overhead due to authentication, Rational

developers decided to hold client license for 90 minutes. No way to change timeout period.

• “The gods are just, and of our pleasant vicesMake instruments to plague us.” -- King Lear, V. iii

• Rational’s suggestion: buy as many CQ licenses as CC licenses.

Upside / Downside

• Faster connection for checkins and checkouts• No license usage• No ClearQuest DB storage yet (working on

database structures)• Need to use cqperl (Perl 5.6) to use

Win32::ODBC library

A final tip

• When moving a VOB from Windows NT to Windows 2000--

• fix_prot (it’s in the CCHOME/etc/utils directory) the VOBs and views

• fix_prot -r -root -chown <owner> -chgrp <group> <storage directory>

• cleartool protectvob the VOBs• Reboot clients and server to restart MVFS

(because it’s a Windows driver)
