The default behavior is to display the needed commands for the admin to execute manually.

Issues: CT-1273

tpm diag now collects routing table information via route -n , and has two new command-line arguments: --include and --groups.

--include specifies a comma-separated list of subroutines to include. Any gather subroutine not listed will be skipped.

{
 "awsS3Path" : "s3://your-bucket-for-redshift/redshift-test",

prefer-ip-stack="6"

By default, IPv4 is enabled, which equates to the value of "4" in the above property.

Issues: CT-1537

Default systemd configuration files for Tungsten components no longer specifies the tungsten group to execute the command. This will prevent file access issues when tungsten user belongs to several groups.

Issues: CT-1550

When services are deployed with systemd and MySQL could not start due to an error, tpm would not be able to later start MySQL

Issues: CT-1734

Issuing dsctl set [--reset] against Aurora source and targets would fail with Access Denied errors. This is due to the inability to disable Binary Logging for specific transactions which dsctl issues. The errors did not prevent dsctl from working, however they were misleading.

Issues: CT-1040

In certain cases, tprovision would not be able to find the binary log position of the backup when taken from a primary. This has been fixed.

Issues: CT-1085

Issues: CT-1248

The tpm connector command now handles special characters in the password string.

Issues: CT-1258

The tpm update command will now exit with an error if any files not owned by the configured Tungsten OS user are found in the Tungsten installation directory.

For example, if the OS user is tungsten and the installation directory is /opt/continuent, containing the file /opt/continuent/thl/archived_thl.zip owned by root would cause something like the following error to be produced, and tpm update would exit:

Foreign-owned files found!

Located files in the Tungsten installed directory /opt/continuent
that are not owned by the Tungsten OS user (tungsten):

/opt/continuent/thl/archived_thl.zip

Please change the ownership of these files to OS user "tungsten"
using the chown command as root via sudo, then rerun the `tpm update` command.

For example:
shell> sudo chown -R tungsten:tungsten /opt/continuent

Issues: CT-1260

Fixes a monitoring bug with users using caching_sha2_password.

Issues: CT-1406

This fixes a bug that prevented tpm mysql from working on applier hosts running MySQL.

Issues: CT-1414

The tpm ask command no longer calls Data::Dumper when it is not available.

Issues: CT-1626

tpm now parses the MYSQL SSL related setting correctly.

Issues: CT-1662

Issues: CT-1664

When MySql services where badly installed, some distribution could show a “not-found” status within systemctl, confusing tpm

Issues: CT-1677

The tpm command now communicates properly when there is no INI configuration file or staging-method deploy.cfg configuration defined.

Issues: CT-1712

Issues: CT-1324

The replicator metadata cache will now correctly handle table names when lower_case_table_names=1 is set in the MySQL configuration.

Issues: CT-651

When using parallel apply, the replicator would error with a Foreign Key constraint error if statements were issued against two or more objects that shared the same name, but with different case sensitivity, for example:

mysql> create table testtable;
mysql> drop table testtable;
mysql> create table TestTable;

Issues: CT-1259

A change in the way MySQL logs CREATE TABLE AS SELECT in the Binary Logs from v8.0.20 onwards, meant these transactions would previously fail.

Issues: CT-1301

Fixes occurences of NullPointerException that would occur when bringing the replicator online before MySQL was started.

Issues: CT-1348

For row based events, SQL modes were not displayed in the THL output. This is now fixed.

Issues: CT-1440

When connecting to a THL server, a client will now connect to the next available host in its THL uri, if the first does not have the sequence number that the client requires. The client will then fail only if none of the hosts from the uri can provide the needed sequence number.

Issues: CT-1558

Fixed an issue when using Parallel apply that would show a NullPointerException in case an event could either not be found or be corrupted in THL. This will now display a correct message Missing or corrupted event from storage

Issues: CT-1350

The BidiRemoteSlaveFilter could fail to correctly flag fragmented events in unprivileged environments (Aurora, for example) In such an environment (multi-active, unprivileged database access), a new setting was introduced to force extraction process to read ahead to the last fragment to detect the service name (false by default). Enabled with repl_svc_extractor_multi_frag_service_detection=true

Issues: CT-1351
