Service bulletin 213: Performance degradation can occur with APAR PJ47096 applied

Preventive Service Planning


Abstract

With APAR PJ47096 applied, increased utilization and degraded system performance can occur when shared SSL support is used. Apply APAR PJ48046 to resolve this issue.

Content

When the SSL_read and SSL_write APIs are issued, system processing within the shared SSL daemon issues a tpf_eheap_locate API and performs a serial search for ECB heap storage. This processing can lead to a significant increase in CPU utilization and overall performance degradation, which might introduce system stability and throughput issues. Apply APAR PJ48046 to resolve this issue.

For more information, see the PJ48046 APEDIT.
