Bill Burcham created GEODE-9681:
-----------------------------------

             Summary: Explain "view persistence" (.dat) files
                 Key: GEODE-9681
                 URL: https://issues.apache.org/jira/browse/GEODE-9681
             Project: Geode
          Issue Type: Improvement
          Components: docs, membership
    Affects Versions: 1.15.0
            Reporter: Bill Burcham


The [javadoc describes|https://geode.apache.org/releases/latest/javadoc/org/apache/geode/distributed/Locator.html] the view persistence ({{.dat}}) file:

{noformat}
Locators persist membership information in a locatorXXXview.dat file. This file is used to recover information about the cluster when a locator starts if there are no other currently running locators. It allows the restarted locator to rejoin the cluster.
{noformat}

When this ticket is complete, the [Running Geode Locator Processes|https://geode.apache.org/docs/guide/114/configuring/running/running_the_locator.html] page will mention the view persistence {{.dat}} file and explain its purpose. Also, the page will highlight the split-brain vulnerabilities (see #GEODE-9680) associated with missing or stale {{.dat}} files.
