Use environment variables
Attention: Misuse of certain environment variables can cause irreparable damage to the RPM database.You must have the following environment variables set when you attempt to uninstall WebSphere MQ V5.3 for Linux for Intel:
- export LD_ASSUME_KERNEL=2.4.19
- export RPM_FORCE_NPTL=1
If these variables are not set to the specified values when you attempt to uninstall WebSphere MQ V 5.3, it can cause unrecoverable damage to the RPM database. This is due to a known Linux issue, see https://rhn.redhat.com/errata/RHEA-2004-010.html for more information.
WebSphere MQ for Linux (x86 platform), V6.0 is not affected by this issue. When you have completed your migration to WebSphere MQ V6.0, unset these variables to take advantage of the performance benefits of the Native Linux Posix Thread Library (NPTL).
