Verification of upgrade bundle available on Data Collector server

SmartUpdaterThread validates both bundles in the following order.

  • Version comparison: Bundle's version is compared against the expected upgrade version received from IT Analytics Data Receiver.

  • Checksum verification: Checksum is retrieved from a Data Receiver, and compared against the one generated using the bundle available locally on the Data Collector server.

  • Signed Jar verification: Java utility jarsigner is used to verify whether the bundle is signed or not.

  • At any point, if the verification fails, the upgrade fails and bundles are deleted from the Data Collector server.

When to verify upgrade bundle?

When the IT Analytics Portal is upgraded successfully to a newer version, and subsequently, the Data Collector upgrade fails due to errors like:

  • Collector bundle download failed for 11.2.1.03 Premature EOF

  • Upgrade Manager upgrade failed. Exception is : Premature EOF

These errors indicate that the upgrade bundle could not be downloaded successfully on to the Data Collector server due to slow network/low bandwidth.

How to use the upgrade bundle?

Prerequisites:

  • These errors indicate that the upgrade bundle could not be downloaded successfully on to the Data Collector server due to slow network/low bandwidth.

  • Requires access permissions to copy files to/from Data Collector Server and Portal Server.

Notations:

  • <PORTAL_APTARE_HOME>  is where Portal is installed. Default value:

    Linux Portal: /opt/aptare

    Windows Portal: <drive>:\opt\aptare

  • <DC_APTARE_HOME> is where the Data Collector is installed. Default values:

    Data Collector on Linux: /user/openv/analyticscollector

    Data Collectors on Windows: C:\Program Files\Veritas\AnalyticsCollector

  • <OS> is the Operating System where Data Collector software is installed.
