Oracle 10gR2/Solaris x64: Must Have Patches for E-Business Suite 11.5.10


If you have an Oracle E-Business Suite 11.5.10 database running on Oracle 10gR2 (10.2.0.2) / Solaris x86-64 platform, make sure you have the following two Oracle patches to avoid concurrency issues and intermittent Oracle shadow process crashes.

Oracle patches

1) 4770693 BUG: Intel Solaris: Unnecessary latch sleeps by default
2) 5666714 BUG: ORA-7445 ON DELETE

Symptoms

1) If the top 5 database timed events look something similar to the following in AWR, it is very likely that the database is running into the bug 4770693 Intel Solaris: Unnecessary latch sleeps by default.

Top 5 Timed Events

EventWaitsTime(s)Avg
Wait(ms)
% Total
Call Time
Wait Class
latch: cache buffers chains 94,301 169,403 1,796 86.1Concurrency

wait list latch free 247,466 4,756 19 2.4Other
buffer busy waits 14,928 1,382 93 .7Concurrency
db file sequential read 98,750 552 6 .3User I/O


Apply Oracle server patch 4770693 to get rid of the concurrency issue(s). Note that the fix will be part of 10.2.0.3.

2) If the application becomes unstable and if you notice core dumps in cdump directory, have a look at the corresponding stack traces generated in udump directory. If the call stack looks similar to the following stack, apply Oracle server patch 5666714 to overcome this problem.

Alert log will have the following errors:
