Systems Used Linux RedHat 6.2 + db2 6.1
Systems Used Linux RedHat 7.1 + db2 7.2
I'm using php with ibm-db2 and I'm experiencing a large amount of memory used by
apache. Up to 20-30 MB !!!
If I stress the system with simple or complex SQL queries the used memory amount
grows.
an hack that I've tried is to impose a memory limit patch to php, but I've obtained no
positive results.
The module is compiled as shared.
there is another problem with libpthread.so that i have to preload with
LD_PRELOAD=path_to lipthread.so.*
this is my configure line
'./configure' '--disable-debug' \
'--disable-pear' \
'--disable-static' \
'--enable-pic' \
'--enable-inline-optimization' \
'--enable-track-vars' '--with-apxs' \
'--with-xml' \
'--with-ftp'\
'--with-gd' \
'--with-ttf' \
'--enable-freetype-4bit-antialias-hack' '--enable-sysvsem'
'--enable-sysvshm' \
'--enable-calendar' \
'--without-mysql' \
'--enable-safe-mode' \
'--with-system-regex' \
'--with-prefix=/usr' \
'--with-config-file-path=/etc/httpd/' \
'--with-versioning' \
'--with-gettext=/bin/gettex' \
'--with-ibm-db2=shared' \
'--with-ldap=shared' \
'--enable-memory-limit'
this is ldd of libphp.so
libpam.so.0 => /lib/libpam.so.0 (0x40129000)
libdl.so.2 => /lib/libdl.so.2 (0x40131000)

/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
and this is ldd of odbc.so
libdb2.so.1 => /usr/IBMdb2/V7.1/lib/libdb2.so.1 (0x4002c000)
libc.so.6 => /lib/i686/libc.so.6 (0x4088c000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x409bc000)
libdl.so.2 => /lib/libdl.so.2 (0x409ea000)
libpthread.so.0 => /lib/i686/libpthread.so.0 (0x409ee000)
libstdc++-libc6.1-1.so.2 => /usr/lib/libstdc++-libc6.1-1.so.2 (0x40a03000)
libm.so.6 => /lib/i686/libm.so.6 (0x40a46000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
the module odbc.so must be loaded with dl('odbc.so') each time from the script, if i
include this is php.ini the httpd give me a segmentation fault (problem to resolve
libpthread???)
