Last updated on FEBRUARY 27, 2019
Applies to:
Oracle Net Services - Version 10.1.0.3.0 to 10.2.0.1.0 [Release 10.1 to 10.2]HP-UX Itanium
Symptoms
Oracle 10g clients using LDAP resolution is taking a significant amount of time (> 60 seconds) to connect.
Oracle Net client trace shows most of the time is spent in following calls:
[27-JUN-2007 23:22:14:406] nzumalloc: entry
[27-JUN-2007 23:22:14:406] nzumalloc: entry
..
<< Repeats 500+ times >>
..
[27-JUN-2007 23:24:09:530] nzumalloc: entry
[27-JUN-2007 23:24:09:530] nzumalloc: entry
[27-JUN-2007 23:22:14:406] nzumalloc: entry
..
<< Repeats 500+ times >>
..
[27-JUN-2007 23:24:09:530] nzumalloc: entry
[27-JUN-2007 23:24:09:530] nzumalloc: entry
In above example of Oracle Net trace, these calls are taking almost 2 minutes during the LDAP resolution.Under normal conditions, these calls should take a few seconds to complete.
