Before Installing the Service Pack

If you are installing DDE 9.1 SP 1 on the same system that a patched version of Oracle 10g runs, please read this section. A bug has been identified when installing DDE 9.1 sp 1 in this configuration. The bug is:

CQ00276994: DDE 9.1 service pack 1 will not work when Oracle 10g / ora10g is loaded on the same machine. Conflict with variable perl5lib.

The bug surfaces only when DDE 9.1 service pack 1 and Oracle 9 Release 2 and above are installed on the same machine and when Oracle 9 release 2 and above has had an interim patch applied.

Problem Description

The patching interface for Oracle 9i Release 2 and all later versions installs an application named Opatch. Opatch is the patch engine used by Oracle for installing interim patches. Opatch is implemented as a set of PERL (5.6) scripts which use the Java API and requires a PERL interpreter on the target system. Opatch accesses PERL through an environment variable named PERL5LIB. If DDE and Opatch are installed on the same PC the version of PERL installed by Opatch will conflict with the version of PERL used by DDE. The conflict prevents DDE from translating data.

Symptom

If Opatch has been installed a DDE user will see an HTTP 404 error message when a translation is attempted.

Determining the Cause

To determine that the problem is due to a PERL conflict you can ask your Oracle Database Administrator if Opatch has been installed or use the command line to test the DDE translation script. You can execute the following from the command prompt to determine if there is a PERL conflict:

1. Create a command window
2. Type the path to the PERL library installed by DDE
   
   

   <DDE Install Directory>\Perl\bin\perl5.8.4.exe <Webserver scripts directory>spatialDirect.pl

   If the result is as follows, the PERL conflict is the cause.

   Perl lib version (v5.6.1) doesn't match executable version (v5.8.4) at C:\oracle\product\10.1.0\db_1\perl\5.6.1\lib\MSWin32-x86/Config.pm line 21.
   Compilation failed in require at C:/Program Files/DDE/Perl/lib/Time/Local.pm line 5.

Resolution

The problem can be resolved through a workaround. The workaround is accomplished by changing the name of or removing the PERL5LIB variable, or by changing an Opatch script named Opatch.bat. PERL5LIB could be changed to zzPERL5LIB while DDE is being used. When Oracle needs to be patched DDE could be shutdown and zzPERL5LIB reset to PERL5LIB. Or, PERL5LIB variable could be removed until a patch needs to be applied. If you change the PERL5LIB variable you should reboot. When a patch needs to be applied PERL5LIB could be created. The Opatch.bat script includes instructions for setting the path to the PERL compiler.

Post 9.1 releases of DDE will not use CGI and PERL will not be installed thus eliminating the conflict.
