The init scripts cfmx7search or coldfusionmx7 hang the system when booting linux

Hans Omli recently presented the following problem to me:

I've run into an issue installing ColdFusion MX 7 on Red Hat Enterprise Linux 4 Update 2 or Update 3. The same issue doesn't occur on the original release of RHEL 4 or Update 1. The issue is that after restarting, linux pauses at 'Starting coldfusionmx7: ' until you press Enter, after which the boot process continues. Haven't been able to track down a workaround yet...

To be complete, the issue also appears on the original release and Update 1 of RHEL 4 after running up2date to apply available security updates. I think I've narrowed the issue down to the selinux-policy-targeted package. When I get a chance, I plan to diff selinux-policy-targeted-1.17.30-2.88 (RHEL4-U1) and selinux-policy-targeted-1.17.30-2.110 (RHEL4-U2) to figure out what change(s) may be causing the issue.


This was the fourth report I've heard of this problem, and until today I've never been able to reproduce it when using the original RHEL4 release. Hans provided the clue that it only occurred in recent updates to RHEL (or CentOS), so I downloaded CentOS 4.3 which has the updated SELINUX policy, and then installed ColdFusion 7.01 to let the fun begin.

The short answer and solution ...

Workaround for several known issues regarding Sandbox Security and ColdFusion MX

I've recently encountered a variety of reports on the topic of ColdFusion MX 7.x Sandbox Security (SBS). Here I summarize and explain how to resolve each one:

  1. Datasource names are case sensitive in SBS
  2. File Uploads require SBS permission on a temp directory
  3. CFDOCUMENT requires SBS permission to System Fonts
  4. Multiserver Configuration requires manual edit to jvm.config

Migrating applications across a six year gap in ColdFusion server implementation

Mike Munhall of Ceridian Recruiting posts his experience with migrating from ColdFusion 4.5. to CFMX 7.01, a jump of 3 major versions but more like 4 since CFMX 6.1 was significantly different from 6.0 in many ways.

The ColdFusion MX 6.0 Migration Guide is a chapter of documentation intended to help cross the bridge from the C++ based server CF 5 to the Java and J2EE based CFMX 6.0. Changes in how the ColdFusion server was implemented required a migration guide and release notes to make the transisition smoother. Mike explains some unexpected problems that arose when faced with the challenge of a six year difference in ColdFusion server versions.

Concord's Second Most Celebrated Holiday

The town of Concord, Massachusetts was settled about 140 years before the founding of the United States. The citizens take great pride in the town's role towards this country's independence, and the annual Patriot's Day holiday is without question the most celebrated event in the area, comemorating the Battle of Lexington and Concord on April 19, 1775, or as Emerson put it, The Shot Heard Round The World.

Yet Concord does make a very good turn out for Independence Day, the national holiday on July 4th. The town shines while stars and stripes abound on door stops, mail boxes, and flag poles.

Share my photo gallery of scenes through out Concord, MA taken during early morning before the town folks turned out.
