Recently at a customer, I faced a new issue I didn’t see before on the xPlore Dsearch component. Basically, the processes appeared to be starting and the “dsearchadmin.war” was deployed properly but it always failed for the “dsearch.war” upon startup of WildFly. However, it was possible to “deploy” it once WildFly was running… This issue wasn’t too complex to debug because some interesting hints were displayed on the logs but it’s an interesting behavior because you could think that everything is running while it’s not. The initial issue was the following one:

[xplore@ds-0 ~]$ cd $JBOSS_HOME/server

[xplore@ds-0 server]$ $STARTSTOP start
  **
  **  The PrimaryDsearch is shutdown

As you can see above, there are no cps_daemon child processes for the PrimaryDsearch, which is a good indication that even if the WildFly process is running, the xPlore PrimaryDsearch isn’t fully up&running and that something went wrong. On the logs, and especially on the stack trace above, the issue appears to be on the initialization/startup of the PrimaryDsearch and more specifically around its included CPS. Looking at the URL obviously fails since the application has been switched to failed state so the first thing I tried was simply to test a redeploy of the application. The custom script $STARTSTOP we are using (c.f. above) already take care to force a redeployment, in case one of the Applications is in “undeployed” or “failed” state before WildFly starts, but I still tried to do it manually during runtime, to see if it would work:

Somehow, it looked like WildFly was able to deploy the dsearch.war application this time… So, all happy, I looked at the server.log again to confirm that:

[xplore@ds-0 deployments]$

As you can see above, the initial deployment failed (12:06:40) but then, by manually asking for a redeployment (12:08:51), it looks like WildFly was able to successfully deploy it, no? Let’s look at the URL:

[xplore@ds-0 deployments]$ curl -kI http://`hostname -f`:9300/dsearch
HTTP/1.1 302 Found
Connection: keep-alive
Server: FT1
Location: http://ds-0.domain.com:9300/dsearch/
Content-Length: 0
Date: Wed, 13 Jul 2022 12:10:01 GMT

[xplore@ds-0 deployments]$

The URL is now responding with a correct “302 Found” which means that it looks good, right? To cross-check, I just added the “/” at the end to use the real redirected location:

[xplore@ds-0 deployments]$ curl -kI http://`hostname -f`:9300/dsearch/
HTTP/1.1 404 Not Found
Connection: keep-alive
Server: FT1
Content-Length: 0
Date: Wed, 13 Jul 2022 12:10:05 GMT

[xplore@ds-0 deployments]$

That’s very peculiar, the deployment appears to be successful, and the first URL appears to work as well but if you really look behind the first link, it’s not working. Of course, the cps_daemon child processes of the PrimaryDsearch are also not present. Therefore, you might think that it started but it didn’t. As mentioned previously, the stack trace appeared to be linked to CPS initialization. Therefore, I looked at the CPS configuration file which is, by default, $XPLORE_HOME/dsearch/cps/cps_daemon/###DS_NAME###_local_configuration.xml for a Dsearch or $XPLORE_HOME/dsearch/cps/cps_daemon/###CPS_NAME###_configuration.xml for a CPS Only. In any cases, you can find the correct name/path of this file in the “cps.properties” file (for a CPS Only, it’s inside the cps.war, not inside the dsearch.war):

[xplore@ds-0 deployments]$ cps_conf_file=$(grep cps.configuration.file dsearch.war/WEB-INF/classes/cps.properties | awk -F= '{print $2}')
[xplore@ds-0 deployments]$
[xplore@ds-0 deployments]$ echo ${cps_conf_file}
$XPLORE_HOME/dsearch/cps/cps_daemon/PrimaryDsearch_local_configuration.xml
[xplore@ds-0 deployments]$
[xplore@ds-0 deployments]$ ls -l ${cps_conf_file}
ls: cannot access $XPLORE_HOME/dsearch/cps/cps_daemon/PrimaryDsearch_local_configuration.xml: No such file or directory
[xplore@ds-0 deployments]$

It appears that the CPS configuration file is gone and that is what is causing this issue, since these processes cannot be initialized. This file was unfortunately removed by mistake a few hours earlier and because of that, the xPlore processes couldn’t start anymore. Restoring the file (from the closest backup) and then restarting xPlore processes was sufficient to have the services back online (since the “/dsearch” isn’t really reachable, there are obviously errors during the shutdown):

[xplore@ds-0 deployments]$ $STARTSTOP stop
  **
  **  The PrimaryDsearch is running with PID: 9178
  **

}

[xplore@ds-0 deployments]$

And cross-checking with the logs and URLs, it started properly:

The HTTP response code of 259 is normal for the dsearch URL so it shows that it works properly now. All cps_daemon child processes are also present and there are no issues on any logs. So just to conclude on this blog, it’s not because it appears that WildFly properly deployed the xPlore applications that they are really working! Make sure to always check the URLs and processes, that’s always a better indication. The best is of course to test xPlore end-to-end from Repository Searches & Indexing but that can take some time if it’s not automated/scripted.
