Default php with oci8

Hi,
I am compiling php 5.2.5 with OCI8 on centOS 5. I have installed the
following from oracle

oracle-instantclient-basic-10.2.0.3-1
oracle-instantclient-sqlplus-10.2.0.3-1
oracle-instantclient-devel-10.2.0.3-1

These were the compile used while configure php

'./configure' '--prefix=/usr/local/php-5.2.5' '--cache-file=../config.cache'
'--with-libdir=lib' '--with-config-file-path=/usr/local/php-5.2.5/etc'

Compile and install was successful. Apache was not working and these are the
sealert messages, i am putting here only summary, raw audit message and
suggestions, which i followed in the same order below to make Apache work


1. Summary
SELinux is preventing /usr/local/php-5.2.5/bin/php from loading
/usr/lib/oracle/10.2.0.3/client/lib/libnnz10.so which requires text
relocation.

Raw Audit Messages

avc: denied { execmod } for comm="php" dev=dm-0 egid=0 euid=0
exe="/usr/local/php-5.2.5/bin/php" exit=-13 fsgid=0 fsuid=0 gid=0 items=0
path="/usr/lib/oracle/10.2.0.3/client/lib/libnnz10.so" pid=27356

tcontext=system_ubject_r:lib_t:s0 tty=pts1 uid=0

chcon -t textrel_shlib_t /usr/lib/oracle/10.2.0.3/client/lib/*.so


2. SELinux is preventing /usr/sbin/httpd (httpd_t) "execstack" access to
<Unknown> (httpd_t).
Raw Audit Messages

avc: denied { execstack } for comm="httpd" egid=0 euid=0
exe="/usr/sbin/httpd"
exit=-13 fsgid=0 fsuid=0 gid=0 items=0 pid=27907
scontext=root:system_r:httpd_t:s0 sgid=0 subj=root:system_r:httpd_t:s0
suid=0
tclass=process tcontext=root:system_r:httpd_t:s0 tty=(none) uid=0

setsebool -P httpd_disable_trans=1

3. Summary
SELinux is preventing /usr/sbin/httpd from changing the access
protection of
memory on the heap.
Raw Audit Messages

avc: denied { execheap } for comm="httpd" egid=0 euid=0
exe="/usr/sbin/httpd"
exit=0 fsgid=0 fsuid=0 gid=0 items=0 pid=3913
scontext=root:system_r:initrc_t:s0
sgid=0 subj=root:system_r:initrc_t:s0 suid=0 tclass=process
tcontext=root:system_r:initrc_t:s0 tty=(none) uid=0

setsebool -P allow_execheap=1



Has anybody compiled PHP 5 with Oracle client on Redhat or Centos 5 with out
any selinux issues? Is this the known issue or my procedures are wrong. I
have tried compiling couple of weeks back with Red Hat ent5 php source rpms
and got the same selinux errors. Any possible help to put back
allow_execheap=0 httpd_disable_trans=0.

Thanks.
