Applies to:Oracle Exadata Storage Server Software - Version 184.108.40.206.0 to 220.127.116.11.0 [Release 11.2]
Information in this document applies to any platform.
Temporarily running mixed Exadata Storage Server Software versions (e.g. during rolling cell patching or rack expansion with new hardware) on the storage cells is a common practice. However, if some of the Storage Cells involved are running version 18.104.22.168.0, while the Compute Nodes are using Oracle Database software version 22.214.171.124 or 126.96.36.199 without patch 17854520 installed, the system is exposed to database hangs or crashes.
Database instances may crash with ORA-7445[OSSCAP_RECOMPUTE_MIN]
Some Exadata Storage Cells running version 188.8.131.52.0 were recently introduced into the Exadata 184.108.40.206 or 220.127.116.11 Cluster.
Examples of this situation include:
a.) you are performing rolling cell patching
b.) rack expansion with new Exadata hardware running version 18.104.22.168.0
