SQLPLUS connection to database hangs when Vintela software is installed (Doc ID 419285.1)

Last updated on JULY 15, 2007

Applies to:

Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 10.2.0.3
Linux x86
Quest Vintela Authentication Services (VAS)
Quest Vintela Group Policy (VGP)

Symptoms

Attempts to connect locally to the database using SQLPLUS hang. SQLPLUS launches successfully (i.e. sqlplus /nolog), however attempting to connect to the database from within SQLPLUS hangs.

A system call trace of the SQLPLUS client process (e.g. using strace, truss) denotes the following output:
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x41695000
read(10, "#\n# hosts This file desc"..., 4096) = 756
read(10, "", 4096) = 0
close(10) = 0
munmap(0x41695000, 4096) = 0
getuid32() = 214
futex(0x41221138, FUTEX_WAIT, 2, NULL <unfinished ...> 

Changes

Quest Vintela Authentication Services (VAS) and Vintela Group Policy (VGP) were recently implemented within the environment. VAS/VGP are third-party authentication software, a description of which is available from http://www.vintela.com.
