Affected Products and Versions
| Affected Product(s) | Version(s) |
| IBM Operations Analytics Predictive Insights | 1.3.6 |
Remediation/Fixes
For RHEL 7 / CentOS 7 servers that host the Cassandra database, it is enough to ensure that the glibc, glibc-common and glibc-devel packages are at least up to version 2.17-292
The command here will check those versions:
yum list installed | grep glibc
For RHEL 6 / CentOS 6 servers that host the Cassandra database, it is advised to remove the Python 2.7 installation.
This will disable the use of the cqlsh command.
This command is not critical to the use of the Predictive Insights REST Mediation service so Predictive Insights will not be affected.
Note also that it is strongly advised that any RHEL 6 / CentOS 6 servers should be upgraded or replaced with RHEL 7 / CentOS 7 servers.
