AEM 63 - This and That

FIND_BINARY_LOCATION_ON_FILE_SYSTEM

With AEM 63, the default store for binaries is File Data Store - FDS; to find the location of binary on file system

     1) Get the jcr:content/metadata/dam:sha1 of binary from CRXDE eg. 4608b968ad44797313ee7d6710be9c3dfba1e937

     2) Search for the file with name as dam:shal value in <path_to_aem_author_install>/author/crx-quickstart/repository

     3) To be sure, just add the extension of binary eg. 4608b968ad44797313ee7d6710be9c3dfba1e937.jpg, dont forget to change it back to no extension

REPORT_PATHS_HTTP_STATUS_ERROR_CODE

Scan access.log files and report page paths generating errors sorted by most frequent to least frequent (thank you Himanshu Pathak for the tip, more details here)

awk '{if($9!=200 && $9!=304 && $9!=302) { print $7 "\t" $9}}' access.log*  | sort | uniq -c | sort -nr

DELETE_NODE_USING_OAK-RUN

If the sling repository is not starting, you receive errors like Exception in a SlingRepositoryInitializer, 503 AuthenticationSupport service missing in error logs and offline/cmdline access to repo is required to add/delete nodes, oak-run jar console mode might help...

             1) Download latest oak-run jar https://repo1.maven.org/maven2/org/apache/jackrabbit/oak-run/

             2) Access the repo using command : > java -jar oak-run-1.9.9.jar console crx-quickstart/repository/segmentstore --read-write 

             3) Load the script to delete nodes eg. > :load https://gist.githubusercontent.com/stillalex/43c49af065e3dd1fd5bf/raw/9e726a59f75b46e7b474f7ac763b0888d5a3f0c3/rmNode.groovy

             4) Delete node eg. > rmNode(session, "/apps/delete-me-using-oak-run.txt")

The delete groovy script in https://gist.githubusercontent.com/stillalex/43c49af065e3dd1fd5bf/raw/9e726a59f75b46e7b474f7ac763b0888d5a3f0c3/rmNode.groovy

import org.apache.jackrabbit.oak.spi.commit.CommitInfo
import org.apache.jackrabbit.oak.spi.commit.EmptyHook
import org.apache.jackrabbit.oak.spi.state.NodeStore
import org.apache.jackrabbit.oak.commons.PathUtils

def rmNode(def session, String path) {
    println "Removing node ${path}"

    NodeStore ns = session.store
    def nb = ns.root.builder()

    def aBuilder = nb
    for(p in PathUtils.elements(path)) {  aBuilder = aBuilder.getChildNode(p) }

    if(aBuilder.exists()) {
        rm = aBuilder.remove()
        ns.merge(nb, EmptyHook.INSTANCE, CommitInfo.EMPTY)
        return rm
    } else {
        println "Node ${path} doesn't exist"
        return false
    }
}
