Impact Assessment
Impact Description

This is a service release. It contains new features as well as fixes for client-reported and internally found defects.

Test Results

Definitions

Regression: An error in the Maintenance Delivery Vehicle (MDV) that produces incorrect or unexpected behavior causing a supported feature to stop functioning as designed.
This includes:

  • Coding errors that cause a regression
  • Documentation or packaging problems that cause a regression
  • Errors reported in a new function delivered in a MDV that cause a regression

Incomplete: An error in the MDV has not regressed, but does not work as designed.
This includes:

  • Fixed APARs which did not solve the original problem but did not break anything new
  • APARs reporting documentation errors, such as readme errors, that cause problems applying an MDV but do not lead to a regression


Notes:
  • Regression and incomplete APARs are considered fix-in-error or MDV-in-error
  • Definitions above apply only to valid APARs that result in product fixes (APARs returned as working-as-designed are not assessed for being fix-in-error)
  • Issues in major releases due to new functionality do not apply in this definition

There are no known regressions to report.

Known issues in this release include:

New to this release
TP-76496

When you restart the pods, the dataset service might fail to restart due to a lock on the dataset tables.

To work around this problem, you must run the following commands before you restart the Kubernetes cluster:

1. Run the following command to get the password for the dataset service:

kubectl get secret (my-rtas}-datasets -o yaml -n {namespace}

2. Run the following command to remove the lock from the dataset table:

kubectl exec (my-rtas}-postgresql-0 -n {namespace} -i – sh -c 'PGPASSWORD=<password> psql -U datasets -d datasets -c "DROP TABLE databasechangeloglock"'

3. Run the following command to restart the Kubernetes cluster:

sudo systemctl start k3s

Note: You must substitute the following variables with the actual value in the commands:

(my-rtas} with the release name of the server that you provided during the installation of the server software.

{namespace}with the name of the namespace that you created during the installation of the server software.

<password> with the value that you obtained from Step 1.

TP-76105
TLS1.1 and TLS1 are not supported on Rational Test Automation Server. When you try to run those test assets, the test run fails with an error message about an unsupported security algorithm.
Previous known issues that still apply
TP-73109 When you install Rational Test Automation Server on Lightweight Kubernetes (k3s) and warnings about Ingress deprecation are displayed, you can ignore these warnings.
TP-74534
Before you migrate user data from an earlier version to the latest version, you must publish any created datasets to the Git repository. After the migration, when you try to publish a created dataset it might fail. If it does fail, your only option is to recreate the dataset from scratch.
TP-71416 When you attempt to run an API Suite on Rational Test Automation Server that is installed on OpenShift, and when the API project contains a vast set of resources, you might see that the Execute button in the Execute test asset dialog box is enabled after a delay.
TP-67572 If a dataset is created on the server using a path within an integration tester project and the created CSV file is subsequently referenced in a file data source, then the server presents two datasets relating to the same CSV file.
TP-69141 When you install V10.1.2 of the product, you must decrypt and encrypt each dataset by using the CSV Editor to apply the strongest encryption on each dataset that you used in the earlier version of the product.
TP-71004 Stubs are a tech-preview feature, as such some functionality might not work in all environments.
TP-71956

When you have Rational Test Automation Server on Ubuntu and you run performance test assets such as VU schedule or Rate schedule on a static agent, then the test runs fail with an error message.

To work around this problem, you must add the following parameter to the helm install command during the installation of the server software:

--set networkPolicy.enabled=false

If you have already installed the server software, you can modify the helm parameter value by using the following commands:

helm upgrade {my-rtas} ./ ibm-rtas-prod -n test-system \

  --reuse-values --set networkPolicy.enabled=false

Where {my-rtas} is the name of the release that you provided during the installation of the server software.

TP-71030 After you install the product, if pods restart with the following log message:

ACCESS_REFUSED - Login was refused using the authentication mechanism PLAIN. For details see the broker logfile

You must uninstall the product, delete the pvc data-{my-rtas}-rabbitmq-0, and then install the product.
TP-71950
When the server is under high load, the results microservice might be restarted indefinitely. This happens when the server was killed while holding a database lock.

To work around the problem, perform the following steps:
 
Note: In the following commands, <myrtas> refers to the release name of your choice and <namespace> refers to the name of the namespace that you created during the server installation process.

1. Increase the value of failureThreshold in the following command to start the service:

kubectl patch sts -n <namespace> <myrtas>-results --patch '{"spec": {"template": {"spec": {"containers": {"name": "results","startupProbe":{"failureThreshold":120}}}}'}}

2. Get the database password by running the following command:

kubectl get secret -n <namespace> <myrtas>-results -o jsonpath="{.data.postgresql-password}" | base64 --decode

3. Delete the troublesome database lock by running the following commands:

kubectl exec -n <namespace> <myrtas>-results-postgresql-0 -i – sh -c 'PGPASSWORD=<PASSWORD> psql -U results -d results -c "DROP TABLE DATABASECHANGELOGLOCK"'
kubectl exec -n <namespace> <myrtas>-results-postgresql-0 -i – sh -c 'PGPASSWORD=<PASSWORD> psql -U results -d analytics -c "DROP TABLE DATABASECHANGELOGLOCK"'
kubectl exec -n <namespace> <myrtas>-results-postgresql-0 -i – sh -c 'PGPASSWORD=<PASSWORD> psql -U results -d upload -c "DROP TABLE DATABASECHANGELOGLOCK"'

4. Restart the pod by running the following command:

kubectl delete pod -n <namespace> <myrtas>-results-0
TP-72106 When you expand a dataset from the Datasets page, you cannot navigate to all the cells in the dataset by using the keyboard keys.
TP-69424

When you back up user data of V10.1.0 and restore it on V10.1.1 in the Ubuntu environment, one of the pods does not start. This problem occurs occasionally.

For example, if the result pod does not start, to work around this problem, perform the following steps:

Note: In the following commands, <myrtas> refers to the release name of your choice and <namespace> refers to the name of the namespace that you created during the server installation process.

1. Increase the value of initialDelaySeconds in the following command to start the service:

kubectl patch sts -n <namespace> <myrtas>-results --patch '{"spec": {"template": {"spec": {"containers": [{"name": "results","readinessProbe":{"initialDelaySeconds":180}}]}}}}'

2. Get the database password by running the following command:

kubectl get secret -n <namespace> <myrtas>-results -o jsonpath="{.data.postgresql-password}" | base64 --decode

3. Delete the troublesome database lock by running the following command:

kubectl exec -n <namespace> <myrtas>-results-postgresql-0 -i -- sh -c 'PGPASSWORD=<password> psql -U results -d results -c "DROP TABLE DATABASECHANGELOGLOCK"'

4. Restart the pod by running the following command:

kubectl delete pod -n <namespace> <myrtas>-results-0

TP-66834 During the installation, when you migrate user data from the previous version to V10.1.0, the datasets database does not restore properly. As a result, Data classification information is disappeared from Rational Test Automation Server. 

You must classify the encrypted dataset again by creating a new classification.  
TP-69650 When you run the ubuntu-init.sh script to set up the Kubernetes environment and if the snap command is unavailable, then the command-line interface incorrectly displays the following error message for snapd: 

./ubuntu-init.sh: line 232: ehco: command not found 

The intended message is: 

Error: snapd is not installed 
Please ensure that snapd and snap are installed correctly, for example: 
sudo apt-get install snapd         
TP-59943 If you configure Keycloak to use an LDAP directory service, you should import and synchronize LDAP users to Keycloak. This is a known issue with Keycloak: https://issues.redhat.com/browse/KEYCLOAK-13822

To workaround the problem in Keycloak, on the Add user federation provider page make sure the following settings are set as shown:
Import Users = ON, Sync Registrations = ON, and Cache Policy = DEFAULT
TP-66941 You cannot run tests on the remote static agents connected to Rational Test Automation Server that is installed in an OpenShift environment.
TP-67215 When you configure Rational Test Automation Server test on the UCD server and you enter a value for any of the options available for Show Hidden Properties in the Edit Properties for Run Rational Test Automation Server test window, the values for the options do not work as designed during the test run.

To work around this problem, you must not set any values for any options for Show Hidden Properties.
TP-61446 When you unregister a remote docker agent, running and schedule tests are not canceled. 

To workaround this problem, stop any running tests and cancel any scheduled future executions for that agent before unregistering the remote docker agent.
TP-61311 When you archive a project that has a running test, that test is not stopped. The test completes execution even though it was suppose to stop.
TP-61494 If you unarchive a project that was archived while a test was running, the UI incorrectly shows that the test is still running after the unarchive.

To workaround this problem, make sure there are no tests running when you archive a project.
TP-61446 When you unregister a remote docker agent, running and schedule tests are not canceled.

To workaround this problem, stop any running tests and cancel any scheduled future executions for that agent before unregistering the remote docker agent.
TP-60059 When you schedule a test run and click the "Time" field a list of times displays. If you enter a value in the "Time" field, you cannot move the cursor by using the left or right (<- , -> ) keyboard keys. This is a known issue with the following date picker:

https://github.com/Hacker0x01/react-datepicker/issues/1834

To workaround this problem, use the cursor.
TP-58061 A server shutdown will not stop currently running executions. It is recommended to not shutdown the server if there are active executions running. If the server is shut down while assets are executing the reported status of those executions might be incorrect.
TP-58017 In case of a slow network, the cloning of a repository might fail with an error. In such a case, you can delete and add the repository again.
TP-57198

When working in multiple Rational Test Automation Server tabs concurrently, a message “You are already logged in” might sometimes be displayed. This message occurs when your session has expired and you have since logged in again, but then attempt a navigation action in a browser tab other than the one in which you logged in.

This is a known Keycloak issue. For more information, see https://issues.jboss.org/browse/KEYCLOAK-5179. To workaround this problem, close the tab and open a new one.

Rational Performance Tester Agent

With 10.0, you might expect a reduction in the number of Virtual Users (VUs) supported by IBM Rational Performance Tester Agent depending upon workload characteristics. This variation is the result of the product shipping with OpenJDK™ 8 with OpenJ9 instead of IBM JRE.

OpenJDK 8 with OpenJ9 JRE exhibits a higher utilization of CPU for the workload. Up to 30% or more decrease in the supported VUs capacity may be expected for CPU-bound workloads. However, for memory-bound workloads, a much smaller, if any reduction in VUs capacity may be expected.

If you need higher performance and have access to IBM JRE 8.0.5.35 or later that contains the latest security fixes, you can switch from OpenJDK 8 with OpenJ9 to IBM JRE. For more information, see http://www.ibm.com/support/docview.wss?uid=ibm10956413.
