Important Notice: Changes were introduced in 7.1.0-TIV-NCI-FP0036 which may affect existing product functionality. Please review these Known Issues for a detailed description and recommended corrective actions. The following password related issues are not included in the refresh of Fix Pack 7.1.0.36: DT436172: datasource exception after applying FP36 JZ002: Password property '' too long. Maximum length is 30 For more details including a workaround, refer to https://www.ibm.com/support/pages/node/7231622. DT439964: NOI 1.6.14 Netcool/Impact FP7.1.0.36 problem with migration of restful DSA's encrypted password. DT442736: Following an upgrade to FP36 a correction to the encrypt password is needed in the $IMPACT_HOME/etc/jrexecserver.props file DT442870: Oracle DSA password needs to be re-saved after FP36 update See https://www.ibm.com/support/pages/node/7237238 for more details on these three Known Issues, including the approved workarounds. In addition, the following high priority issues were identified following the publication of Fix Pack 7.1.0.36: DT431998: Customizations to Probable Cause values are overwritten on upgrade to 7.1.0-TIV-NCI-FP0036 DT436954: test_wslistener.sh fails with an exception: java.lang.NoClassDefFoundError: javax.xml.ws.Service DT438930: Java heap memory leak may occur with 7.1.0-TIV-NCI-FP0036 DT440732: FP36 upgrade fails if the nameserver.props contains commented out password value DT455374: Fix Pack upgrade takes excessive time due to slow password migration We strongly recommend evaluating these Known Issues to assess potential impact on your environment. If you require fixes for any of these issues, we recommend upgrading to 7.1.0.37 or later instead. Password Migration During the upgrade process for fix pack 7.1.0.36, the installer will migrate and re-encrypt passwords for the application's configuration and data source files. This migration can be time-consuming and may increase the overall upgrade duration. Plan for additional downtime to accommodate this migration step.

Prerequisites

This fix pack includes all maintenance since the GA of Impact V7.1.0.

This Fix Pack upgrades the bundled version of Java to Java 17.

This fix pack can be applied directly to the base V7.1.0.4 product release or any fix pack or interim fix after this release.

* Attention TBSM Users

For TBSM installations only, upgrading to IBM Tivoli Netcool/Impact 7.1.0.36, or higher, is not supported. Fix Pack 36 for IBM Tivoli Netcool/Impact upgrades its embedded Java JRE to version 17. However, TBSM components rely on Java version 8, and will no longer function, if the embedded Java JRE is upgraded to version 17. For more information:
https://www.ibm.com/support/pages/node/7180959

Known Side Effects

Note that Impact has migrated from using Java 8.0 to using the IBM Semeru Runtime Certified Edition 17.

Some notable differences between the two releases are:
- The directory structure of Java 17 is slightly different from that of Java 8 (for example, there is no longer a jre directory).
- Tools such as ikeyman and ikeycmd are no longer available, and keytool should be used instead.

The Impact documentation, which referred to the old Java 8 structure and command tools, has been updated. For associated topics, refer to the following page:

https://www.ibm.com/support/pages/ibm-tivoli-netcoolimpact-bundles-java-17-part-710-tiv-nci-fp0036

IBM Netcool/Impact V7.1.0 - Replace the GMT timezones to Europe/London for Impact FP35

DT383368: Change timezone for GMT to distinguish from Europe/London

Upgrading to Impact FP35 may offset the time zones in MWM
For more information, visit https://www.ibm.com/support/pages/node/7171978.

The newly added View Links may fail to load properly, specifically when there are special characters in the key value

Resolution
Remove/replace the special characters

Impact Health Checker SSL Certificate check possible failure
Symptom:
Starting with Impact 7.1.0.32, the Health Checker is now performing a check of the SSL certificates to determine whether the certificates are expired.
The Health Checker logic is automatically executed when the Impact fix pack upgrade scripts update_*.bat|sh are used.
If the Health Checker fails due to the SSL Certificate checks, there could be a need to bypass the SSL certificate check.

Resolution:
Before the fix pack upgrade scripts update_*.bat|sh are run/re-run, set the following system environment variable:
impactbypasscertcheck=true

NOTE:
On Windows environments, make sure that after setting the environment variable, a new command window is open and confirming the "echo %impactbypasscertcheck%" command returns the value "true" before re-attempting to re-run the upgrade from that command window. On Unix environments, issue the following command, to confirm the property is set: echo $impactbypasscertcheck

Remove the environment variable "impactbypasscertcheck" after the upgrade has been completed!
NOI Inference Service can exceed its memory limit resulting in a pod restart
Symptom
When running under a heavy event load the Inference Service can exceed its memory limit resulting in a pod restart

Resolution
Scale the Inference Service to include 3 or more replicas. This will ensure that service is not impacted while one pod restarts
Unable to run Event Analytics (EA) config
Symptom
Event Analytics displays a "PKIX path building failed" exception error when opening the on-prem Event Analytics Configuration page, indicating a valid
certification path to the requested target could not be found.

"PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target."

Resolution
Export the Impact UI Certificates and import it into the back-end Impact server's trust store.
For more information:
https://www.ibm.com/docs/en/tivoli-netcoolimpact/7.1?topic=manually-exchanging-certificates-between-impact-servers
WebSphere Liberty 24.0.0.6 and interim fix PH58796
Symptom
If applying WLP interim fix PH58796, SSL connections between the Impact UI and the Impact server backend may fail if the Subject Alternative Name (SAN) entries are not properly defined in the SSL certificates.

Resolution
The WLP interim fix now enforces Host name verification on the SSL certs. The certificates for the front-end and back-end need to be re-issued and need to include the appropriate Subject Alternative Name (SAN) and exchanged between servers.
