WebSphere eXtreme Scale 7.1.1
WebSphere eXtreme Scale 8.5
WebSphere eXtreme Scale 8.6
Remediation/Fixes
Since MD5 signatures are no longer compatible with Java, installing this interim fix will make it incompatible with any WebSphere eXtreme Scale clients and servers that are running with an MD5 certificate. If any WebSphere eXtreme Scale clients or servers are configured with a certificate with an MD5 signature, they must be replaced prior to starting after upgrading to this interim fix. Failing to do so will result in the clients and servers failing to connect to each other. Note that client truststores must be configured to trust the new certificate.
| <Product | VRMF | APAR | Remediation/First Fix |
| WebSphere eXtreme Scale | 7.1 | PI62225 | Refer to the Version 7.1 table in the Recommended Fixes page for WebSphere eXtreme Scale. |
| WebSphere eXtreme Scale | 7.1.1
8.5 8.6 | PI62255 | Refer to the Version 7.1.1, 8.5, or 8.6 table in the Recommended Fixes page for WebSphere eXtreme Scale. |
Workarounds and Mitigations
