Tungsten Clustering 5.1.1 Includes the following changes made in Tungsten Replicator 5.1.1

Tungsten Replicator 5.1.1 is a minor bugfix release that addresses some bugs found in the previous 5.1.0 (in [Tungsten Replicator 5.1 Manual]) release. It is a recommended upgrade for all users.

Bug Fixes

  • Command-line Tools

    • The dsctl (in [Tungsten Replicator 5.1 Manual]) command has been updated:

      • The -ascmd (in [Tungsten Replicator 5.1 Manual]) option has been added to output the current position as a command that you can use verbatim to reset the status. For example:

        shell> dsctl get -ascmd
        dsctl set -seqno 17 -epoch 11 -event-id "mysql-bin.000082:0000000014031577;-1" -source-id "ubuntu"
      • The -reset (in [Tungsten Replicator 5.1 Manual]) option has been added so that the current position can be reset and then set using dsctl set -reset without having to run two separate commands.

      Issues: CT-24

    • The availability and default configuration of some filters has been changed so that certain filters are now available in all configurations. This does not effect existing filter deployments.

      Issues: CT-84

    • The tungsten_provision_slave (in [Tungsten Replicator 5.1 Manual]) command could fail to complete properly due to a problem with the threads created during the provision process.

      Issues: CT-202

  • Backup and Restore

    • The trepctl backup (in [Tungsten Replicator 5.1 Manual]) operation could fail if the system ran out of disk space, or the storage.index file could not be written or become corrrupted. The backup system will now recreate the file if the information could be read properly.

      Issues: CT-122

  • Heterogeneous Replication

    • When creating DDL from an Oracle source for Hadoop using ddlscan (in [Tungsten Replicator 5.1 Manual]), the template that is used to create the metadata file was missing.

      Issues: CT-206
