[CQ/AEM] SegmentNotFoundException

Issue:
When we see the error "org.apache.jackrabbit.oak.plugins.segment.SegmentNotFoundException: Segment 6e0a804f-0d75-48a8-a579-ebf34e58e763 not found" one day, and you can not open any pages, or can access neither crx nor console.

Solution:
We can use oak runnable to check and restore the last good revision into Oak's working directory.

Tool: Oak-run Tool (http://mvnrepository.com/artifact/org.apache.jackrabbit/oak-run)

Check more from http://cqhints.blogspot.com/2015/07/cq6-system-maintaining-repository.html

Step to restore Oak's working directory:
1. Backup all files in ./crx-quickstart/repository/segmentstore/.

2. Run the consistency check
java -jar oak-run-*.jar check -d1 --bin=-1 -p crx-quickstart/repository/segmentstore/

It will search backwards through the revisions until it finds a consistent one:
18:01:51.336 [main] INFO o.a.j.o.p.s.f.t.ConsistencyChecker - Found latest good revision ca9c71ae-1941-4a2d-aaed-c444db7a4c6d:260120

3. Revert the repository to this revision by editing ./crx-quickstart/repository/segmentstore/journal.log and deleting all lines after the line containing the latest good revision.

4. Remove all ./crx-quickstart/repository/segmentstore/*.bak files.

5. Run checkpoint clean-up to remove orphaned checkpoints:
java -jar oak-run-*.jar checkpoints ./crx-quickstart/repository/segmentstore rm-unreferenced

6. Finally compact the repository:
java -jar oak-run-*.jar compact ./crx-quickstart/repository/segmentstore/

If you are using AEM6.0, please do below steps before starting cleanup

Step 1: Download the service pack from Adobe package share (https://www.adobeaemcloud.com/content/marketplace/marketplaceProxy.html?packagePath=/content/companies/public/adobe/packages/aem600/servicepack/AEM-6.0-Service-Pack). Log on to this link, go to “ASSETS” tab and click on “Download to disk: AEM 6.0 Service Pack 1-1.0” link. This should download the service pack to your local system.
Step 2: Restart the AEM server.
Step 3: Once the AEM server is up, go to package manager using “http:<hostname>:<portname>/crx/packmgr” and upload the “AEM 6.0 Service Pack 1-1.0.zip” file downloaded from the package share and click on install.
Step 4: Wait until the full package is installed.
Step 5: Run a check on the instance if everything is working as expected.

[PERFORMANCE] Adobe WEM/CQ performance tuning

Adobe WEM/CQ performance tuning Contents Caching-related configurations CRX Bundle cache CRX Search index handler (Lucene) cache Tar PM index cache Scalability Maintenance Optimizing Tar Files (for Tar Persistence Manager) Data Store Garbage Collection Main documentation you should consult first: http://dev.day.com/docs/en/cq/current/deploying/performance.html http://dev.day.com/content/kb/home/cq5/CQ5Troubleshooting/performancetuningtips.html Caching-related configurations CRX Bundle cache CRX caches bundles, consisting of a node with all its properties. This is used by all bundle-based Persistence Managers. The default size of BundleCache is 8 MB. If this is too small it can cause an excessive number of read-accesses to the underlying persistence layer. Set the bundleCacheSize to something larger than the default.

[Query Builder] Advanced Search

Using the Advanced Search When using a list, select from the 'Build list using' options 'Advanced Search.' This will open a new tab in the list window with one text box labeled: 'Querybuilder Predicate Notation.' This is asking for a few lines of code to define search parameters. Example Code - With Explanations of Results Searching for Pages type=cq:Page property=jcr:content/jcr:title property.value=Places 'type' defines what sort of object you'll be searching for (it's usually a page). 'property' defines what property of the object you'll be filtering by; in this case, its by the title. 'property.value' defines your search term. So this search would be searching all PAGES with the TITLE of PLACES. So it would find every page titled Places. *IMPORTANT* Searches by title ARE case-sensitive, so 'Places' is not the same as 'places'. type=cq:Page path=/cq/sandbox property=jcr:cont...

[MOBILE] Integrating PhoneGap (Apache Cordova) into Your Mobile Applications

Integrating PhoneGap (Apache Cordova) into Your Mobile Applications Leverage PhoneGap (Cordova) JavaScript libraries to integrate device features into your CQ5 applications for mobile devices. For example, the Camera component provides controls that interact with the device camera. Users can operate the web page controls to take photographs and upload them. The PhoneGap Build service compiles web applications consisting of HTML, CSS, and JavaScript as native mobile applications. Native applications can either contain copies of the web content, or download content from the web server. Using the application as a wrapper for live web pages, you can update content without updating the application. Also, users are not bothered with application updates. The PhoneGap Integration package provides a native iOS application that acts as a wrapper for web sites. Users can install the application to access web site content, including PhoneGap-driven device components. The application is pr...
