scsi_id returns nothing on OEL6 running on VMware

Today while I was trying to setup UDEV for an Oracle 12cR1 RAC environment, I found scsi_id returns nothing. After googling around, the solution is as below:

1. shutdown the VM
2. right click the VM, then left click 'Edit Settings'
3. click 'Options' tab
4. click on 'General', then 'Configuration Parameters'
5. click 'Add Row'
6. add a parameter 'disk.EnableUUID' and set it to 'True', click 'OK'

boot up the server and now scsi_id -gud /dev/sdx returns values.

Virus Scan of Documents Uploaded to PeopleSoft

Lately I was assigned a task to configure PeopleSoft Web Server with McAfee VirusScan Enterprise for Linux (which we already owned). It turned out that McAfee VSEL doesn't support ICAP, therefore it won't work with PeopleSoft. Then I was able to download a "Symantec Protection Engine for Cloud Services" trial version and get it to work with weblogic web server. The sample VirusScan.xml file that PeopleSoft provided with PIA installation worked like a charm in a tools 8.52 environment.

PeopleTools 8.52 and libpsio_dir.so

I recently upgraded our SA and HRMS's PeopleTools from 8.50.20 to 8.52.10, the upgrade itself was pretty straight forward and went smoothly. However, it broke the LDAP authentication. When you go to "PeopleTools -> Security -> Directory -> Configure Directory", click the "search" button, click the Directory ID, then click the "Test Connectivity" tab, it just hangs there. Under the "Directory Setup" tab, all settings were confirmed correct. After some research, it turns out the problem was PS_HOME/bin/libpsio_dir.so. It appears PeopleTools 8.52 now delivers libpsio_dir.so under PS_HOME/bin/interfacedrivers, if the old  8.50.20 PS_HOME/bin/ libpsio_dir.so still exists, it will get called instead of the new 8.52.10 PS_HOME/bin/interfacedrivers/libpsio_dir.so, thus causing the "hang" issue. So remember to remove the old libpsio_dir.so after the upgrade is done.
