Issue with stopping ColdFusion after starting from Builder

With the release of ColdFusion Builder there is an option available that provides the ability to start and stop one or more ColdFusion servers from ColdFusion Builder. In fact, you can configure CF Builder to automatically start a CF server when Builder opens, and stop the CF server when Builder closes. The autostart/autostop is convenient for a Development box where you want to minimize resource usage on the system. You can read more about this feature here.

However, if you don't enable the automatic stop/start option, if you ever start ColdFusion server from Builder then close Builder without stopping ColdFusion there, then later you will not be able to stop the ColdFusion server using the standard ColdFusion stop script. I've encountered this on Mac OS X, but since its possible to configure CF Builder to start/stop remote CF servers, it's likely that the problem might occur when using ColdFusion server on Linux or Solaris as well, even though Builder doesn't run on those platforms.

Normally, to stop / start the ColdFusion server from the command line, you would the control script located (typically) at /opt/coldfusion9/bin/coldfusion, such as with ./coldfusion stop. That control script in turn invokes /opt/coldfusion9/runtime/bin/coldfusion9. When calling stop, the control script works by first grepping for any running ColdFusion processes with fgrep, like this: ps -axc | fgrep coldfusion9. If it finds a process listing that matches for the string "coldfusion9" then it stops that process.

Here's what you might see if you try to restart ColdFusion from the command line after it was started but not stopped from Builder:

1$ /opt/ColdFusion9/bin/coldfusion restart
2Restarting ColdFusion 9...
3ColdFusion 9 does not seem to be currently running
4Starting ColdFusion 9...
5The ColdFusion 9 server is starting up and will be available shortly.
6There has been an error starting ColdFusion 9, please check the logs.


The problem of not being able to use that control script to stop ColdFusion server after having started it from Builder arises because of how Builder starts the CF server. Rather than invoking /opt/coldfusion9/runtime/bin/coldfusion9, Builder instead invokes /opt/coldfusion9/runtime/bin/jrun. When the control script tries to grep for the process with a "coldfusion9" string, the control script doesn't find it because Builder invoked runtime/jrun instead of runtime/coldfusion9.

Why the need for runtime/jrun AND runtime/coldfusion9? I have no idea, especially since the files are identical and not symlinked.

view plain print about
1$ pwd
2/opt/ColdFusion9/runtime/bin
3$ diff jrun coldfusion9
4$




I logged ColdFusion server bug 82573 for this where I proposed a change to the bin/coldfusion control script. My suggested change was only shown for Mac OS X, but you can easily change it yourself for the Linux or Solaris blocks in a similar way.

If you want to use my suggested fix on your local Mac OS X dev box, then you can refer to the full example control script containing the fix here: http://pastebin.com/Y7r6sDGu.

For brevity, I won't show the whole script in this blog entry. Instead, here's the diff between the backed up original coldfusion control script which I renamed to 'orig.coldfusion' compared to the fixed version 'coldfusion'.

A ColdFusion Trick for Lost Datasource Password

Here's a quick trick if you don't have a datasource password when creating a new datasource but you do have another ColdFusion server with the same datasource.

Imagine you have two production servers running ColdFusion, each one with different datasources running different applications. What if you have a datasource on one server and you need to create that datasource on the second one but can't find (or don't have) the database password?

All recent ColdFusion versions use the same encryption algorithm for encrypting and decrypting passwords for datasources registered in the CF Administrator. This is why you can copy the ColdFusionX/lib/neo-datasources.xml from one ColdFusion 8 server to another ColdFuson 8 server, and the second server will have all the same datasources as the first. This is a quick way to mirror datasources across different ColdFusion servers.

But now, back to the problem where you have different datasources on each CF server, and you cannot copy over the whole datasource config file. If you don't have the database password, you can create a new datasource on the second server but without supplying a password. The datasource will then fail to verify. However, if you examine the datasource config file from the first server you can find the encrypted version of the password. A snippet from the ColdFusion8/lib/neo-datasource.xml file is shown below. Notice the encrypted version of the password in this xml sections:

view plain print about
1<var name="timeout">
2<number>1200.0</number>
3</var>
4<var name="password">
5<string>RgmrmRQhiQM=</string>
6</var>
7<var name="update">
8<boolean value="true"/>
9</var>
10<var name="drop">
11<boolean value="true"/>
12</var>
13<var name="pooling">
14<boolean value="true"/>
15</var>
16<var name="url">
17<string>
18jdbc:seefusion:{jdbc:mysql://localhost:3306/cfcontact?};driver=com.mysql.jdbc.Driver;dsn=cfcontact;
19</string>
20</var>




In this case the particular datasource has an encrypted version of the password shown as RgmrmRQhiQM=. You could find the datasource of interest in the config file, then find the encrypted version of the password, and copy it to the other neo-datasource.xml config file on the other server. Find the XML node for the failed datasource. It should have no value for the contents of the password field:

view plain print about
1<var name="password">
2<string></string>
3</var>




Then paste the encrypted version of the password in between:

view plain print about
1<var name="password">
2<string>RgmrmRQhiQM=</string>
3</var>




For this to work, the ColdFusion server for where you are pasting the password should be stopped to avoid having ColdFusion overwrite your changes with a copy it already has in memory. Then start ColdFusion after pasting and the datasource will verify.

This can also work between ColdFusion versions. For example, ColdFusion MX 7 used neo-query.xml, and ColdFusion 8 restructured the file into neo-drivers.xml and neo-datasource.xml, but the encryption remained the same. You can copy the encrypted form of the password from a CF7 server and paste it into a CF8 or CF9 datasource config file.

This is a bit of a hack, but it does work.

Starting ColdFusion9 Solr: Using cfsolr in same directory

The cfsolr script for Mac, Linux, and Unix is written such that you must be in the ColdFusion9/solr/ directory when running the script. The script refers to the start.jar file without providing the full path.

The problem is that if you are not in the solr/ directory under the ColdFusion root directory, the cfsolr script echos that Solr has been started or stopped, even though it has not.

Since the standard error is redirected to the standard out with "2>&1" the problem is swallowed and the person performing the operation is led to believe that the operation has been carried out as expected.

Here's a snippet from the ColdFusion9/solr/cfsolr script showing that start.jar is referenced without a full path:

view plain print about
1SOLRSTART='nohup java $JVMARGS -jar start.jar > $SOLR/logs/start.log 2>&1 &'
2SOLRSTOP='nohup java $JVMARGS -jar start.jar --stop > $SOLR/logs/start.log 2>&1'




Looking at the logs, I see that the problem was quietly recorded in a solr log file:

view plain print about
1QAs-iMac:logs QA$ pwd
2/opt/ColdFusion901/solr/logs
3QAs-iMac:logs QA$ cat start.log
4Unable to access jarfile start.jar




The script already has a variable defining the Solr directory path:

view plain print about
1SOLR="/opt/ColdFusion9/solr"




To fix the bug, prefix the reference to start.jar with ${SOLR}/start.jar like this:

view plain print about
1SOLRSTART='nohup java $JVMARGS -jar ${SOLR}/start.jar > $SOLR/logs/start.log 2>&1 &'
2SOLRSTOP='nohup java $JVMARGS -jar ${SOLR}/start.jar --stop > $SOLR/logs/start.log 2>&1'




With that fix, the cfsolr script can be called from any directory outside the solr directory.

Here is an examle of how the script falsely echos that the solr server has stopped or started when it has not (determined by grepping for the process):

view plain print about
1QAs-iMac:opt QA$ pwd
2/opt
3QAs-iMac:opt QA$ ./ColdFusion9/bin/coldfusion stop
4Stopping ColdFusion 9, please wait
5Stopping coldfusion server.stopped
6ColdFusion 9 has been stopped
7QAs-iMac:opt QA$ ps -ef | grep solr

Adobe LiveCycle DataServices for ColdFusion at CFObjective

Allaire's CEO, David OrfaoAfter a decade of working intensely with the ColdFusion server, I'm finally getting the courage to start presenting about it on the conference circuit. As a blogger, tweeter, and contributor to mailing lists I'm very confident helping others solve ColdFusion related problems because I can do that from the quiet comfort of my own desk. However, one of my greatest fears has always been public speaking. I'm the kind of person that feels like I need to know the subject matter cold, so that I can speak from the hip without relying on looking at the slides.




Blackstone Test CDsOver the years, I had some opportunities to present to small groups, and I recall each time feeling the adrenalin surge and my heart pounding. That started with presenting ColdFusion for Unix and Linux as an internal training class at Macromedia. Later, while taking classes at the Harvard Extension School, I was honored to be asked to present to CSCI-253 Developing Web-Based Database Applications. Even more so, I presented twice there in one year. The first time on Building ColdFusion Web Applications with CFEclipse and Dreamweaver, and later on ColdFusion Server Administration




MAX in ActionI've been attending ColdFusion conferences since the days of Allaire DevCon, but had never presented at any of them including MAX. My long time friend in the local ColdFusion Community, Brian Rinaldi, continued to encourage me to present at the local Boston CFUG as a starting point, as well as the new conference that he was organizing, RIA Unleashed, held in Bentley College this past November. The members of the CFUG were kind enough to let me present a draft of a presentation that I was to later give at RIA Unleashed. My presentation topic was Adobe LiveCycle DataServices Data Management for Mere Mortals


ColdFusion 1.5 on Floppy DisksFortunately at RIA Unleashed I was among the very first sessions after the keynote, so there was no time to build up butterflies that morning. If beforehand you would have told me that among the audience front row would be Ben Nadel, Simon Free, and Ray Camden with Tom Jordahl tucked way in the back then I surely would have freaked out. But they were both kind enough to chat with me before hand and even lend some technical assistance getting setup with the A/V, so that really put me at ease. With a firm limit of 50 minutes, I pushed all the way through what should have been a 90 minute talk, all the while trying to remember to speak clearly and loudly. The talk went off pretty much without a hitch as I found myself completely focused on the technical content and not at all worrying about the large room filled with people in front of me. I was delighted at the end when Tom complemented me on talk, which to me was the ultimate satisfaction.




First Unix machine to run ColdFusionI chose LCDS for ColdFusion as a topic because while I was a QA Engineer on the ColdFusion team at Adobe, I was paired with Tom, a Computer Scientist at Adobe who architected the integration between the products. Heck, Tom architected much of ColdFusion itself, and was in fact the original engineer to have ported ColdFusion to run on Unix and Linux back in the day. Tom is a font of information, and I cut my teeth on the feature under his guidance, which was then known as Flex Data Services and later renamed under the LiveCycle brand. I spent many days last summer and fall revisiting all the LCDS documentation again to ensure the quality of my presentation and to mentally prepare me for the upcoming conference.




ColdFusion Team, BangaloreWIth my first conference under my belt, I decided to throw my hat into the ring for the ultimate ColdFusion experience, CFObjective, which is promoted as The Only Enterprise ColdFusion Conference. I'm excited to announce that I have been selected to be a speaker at the conference, which runs from April 22-24th in Minneapolis, Minnesota. The conference is divided into three tracks for technologies related to ColdFusion. I'll be speaking the last day in the Flex track, once again on the topic of LiveCycle DataServices for ColdFusion Developers. Specifically I'll be talking about the prime feature of LCDS, the Data Management capabilities. With any luck I'll be updating my presentation to consider the benefits of working with the latest versions of Adobe software. Here's the brief description and the PDF:




Discussions of Adobe's LiveCycle Data Services are often entered with the same trepidation as those of Organic Chemistry or Quantum Mechanics, but with ColdFusion, building Web applications that manage complex data sets doesn't have to be that scary. Data Management is a pillar of LCDS that offers scalable, real-time data synchronization across very large numbers of connected clients with the benefits of conflict resolution and data pagination.† Come learn how to quickly get up to speed with Data Management by letting ColdFusion do the hard work for you.


If you're seriously interested in ColdFusion, then CFObjective is the conference for you. I hope to see you there.

100th ColdFusion Meetup Today - SeeFusion Giveaway, Too

Today is the 100th episode of the Online ColdFusion Meetup Group, a.k.a. CFMeetup, with Adobe speaker Josh Adams on the topic of ColdFusion as the ideal server-side data provider for iPhone applications. The meeting starts online at 12p ET; find out more here.

This special anniversary of the CFMeetup is made possible by Charlie Arehart, a tireless champion of the ColdFusion Community, who has worked very hard for several years now to improve the organization and execution of meetings and has strived to provide a consistent speaker lineup that give contemporary, meaningful presentations on ColdFusion related topics.

As the founder of ColdFusion Meetup, I'm honored to attend today's anniversary event. In 2004, Macromedia provided employees with unlimited Breeze Meeting accounts (now Adobe Connect) after it acquired Presidia, the original makers of the Flash based meeting software. As Breeze became widely used in Macromedia for internal company meetings, it occurred to me that I could make good use of my unlimited account by starting an online presentation series for the ColdFusion community of developers, and so I formed the Online ColdFusion Meetup Group. The first meeting was February 2005 where I convinced several members of the ColdFusion engineering team to take questions about the release of ColdFusion MX 7 from online guests. Participation grew as I attracted speakers on a monthly basis, and it became a consistent series that ran throughout the year. Later, as I moved from ColdFusion Support to the ColdFusion Engineering team working on Scorpio (CF8), Charlie happily took over the reigns to keep the momentum going... and how has he!

Prizes
Now that I'm a software engineer at Webapper Services providing enterprise level ColdFusion consulting, among the special prize giveaways at today's CFMeetup, Webapper will be giving away a 2-server Enterprise license for SeeFusion - retail value of $600!

SeeFusion is a utility for monitoring and troubleshooting ColdFusion application servers. SeeFusion gives you the ability to "see" how your ColdFusion servers are processing requests in real time.


See you today at CFMeetup!
