Tivoli Directory integrator installed with no execute permissions

I've just finished installing TDI as root.  When I try to apply the FP6 update, I see the following:

server1:/opt/IBM/TDI/V7.1/bin # ./applyUpdates.sh -update /opt/software/TDI/FP6/7.1.0-TIV-TDI-FP0006/TDI-7.1-FP0006.zip
Cannot run /opt/IBM/TDI/V7.1/jvm/jre/bin/jre/bin/java

 I checked permissions for /opt/IBM/TDI/V7.1/jvm/jre/bin/java and it does not have execute permissions:

server1:/opt/IBM/TDI/V7.1/bin # ll /opt/IBM/TDI/V7.1/jvm/jre/bin/java
-rw-r--r-- 1 root root 58848 Dec 15  2009 /opt/IBM/TDI/V7.1/jvm/jre/bin/java

So I made the file executable:

server1:/opt/IBM/TDI/V7.1/bin # chmod +x /opt/IBM/TDI/V7.1/jvm/jre/bin/java
server1:/opt/IBM/TDI/V7.1/bin # ll /opt/IBM/TDI/V7.1/jvm/jre/bin/java
-rwxr-xr-x 1 root root 58848 Dec 15  2009 /opt/IBM/TDI/V7.1/jvm/jre/bin/java

 Then I checked permissions in /opt/IBM/TDI/V7.1/bin and it also did not have executable permission on the files there:

server1:/opt/IBM/TDI/V7.1/bin # ll
total 92

 So I had to change everyone to +x:

 I extracted both CZ9MNML.tar as root, and ftp'd 7.1.0-TIV-TDI-FP0006.zip also as root:

server1:/opt/software/TDI/FP6 # ll
total 39888
-rw-r--r-- 1 root root 40794346 Jul 11 20:24 7.1.0-TIV-TDI-FP0006.zip
However, apparently the install succeeded:

Resolution

The filesystem /tmp, where the installer extracts the installer, had NOEXEC set in /etc/fstab.  This would breat the execute permissions required:

server1:/opt/IBM/WebSphere/AppServer/bin # cat /etc/fstab
/dev/vg_root/lv_tmp  /tmp                 ext3       acl,user_xattr,noexec,nodev        1 2

To fix this, there are two options:

1. Edit /etc/fstab and remove noexec.   Then, execute mount -o remount /tmp; or

2. Set the IATEMPDIR variable to a directory where root has execute permission: export IATEMPDIR=/root/tmp/

I used option 2, and it resolved the issue.
