------------------------------------
Summary: Use JMX mode to reindex on SegmentNodeStore without
requiring manual steps
Key: OAK-7116
URL: https://issues.apache.org/jira/browse/OAK-7116
Project: Jackrabbit Oak
Issue Type: Improvement
Components: run
Reporter: Chetan Mehrotra
Assignee: Chetan Mehrotra
Fix For: 1.10
oak-run indexing for SegmentNodeStore currently require following steps while
performing indexing against a repository which is in use [1]
# Create checkpoint via MBean and pass it as part of cli args
# Perform actual indexing with read only access to repo
# Import the index via MBean operation
As per current documented steps #1 and #3 are manual. This can potentially be
simplified by directly using JMX operation from within oak-run as currently for
accessing SegmentNodeStore oak-run needs to run on same host as actual
application
*JMX Access*
JMX access can be done via following ways
# Application using Oak has JMX remote
## Enabled and same info provided as cli args
## Not enabled - In such a case we can rely on
### pid and [local
connection|https://stackoverflow.com/questions/13252914/how-to-connect-to-a-local-jmx-server-by-knowing-the-process-id]
### Or query all running java prcess jmx and check if SegmentNodeStore repo
path is same as one provided in cli
# Application using OAk
*Proposed Approach*
# Establish the JMX connection
# Create checkpoint using the JMX connection programatically
# Perform indexing with read only access
# Import the index via JMX access
With this indexing support for SegmentNodeStore would be at par with
DocumentNodeStore in terms of ease of use
