Installing Forms – File not found $ORACLE_HOME/lib/libvsn12_ee.a.dbl using GUI

After installing Weblogic and Fusion Middleware (FMW), I came across the following error when I tried to install Forms with OUI GUI. Here’s how I fixed it.



The problem


Here’s what using the proper WLS RHEL 8.3 binaries FMW (which is certified) looks like:

[oracle@formslab]$ ./fmw_12.

event :[] on
event.getData() :[] on
exp : oracle.sysman.nextgen.NextGenInstallerException: java.lang.Exception: oracle.sysman.oii.oiif.oiifb.OiifbEndIterateException: oracle.sysman.oii.oiif.oiifb.OiifbCancelException: File not found /oracle/middleware/lib/libvsn12_ee.a.dbl
msg : java.lang.Exception: oracle.sysman.oii.oiif.oiifb.OiifbEndIterateException: oracle.sysman.oii.oiif.oiifb.OiifbCancelException: File not found /oracle/middleware/lib/libvsn12_ee.a.dbl

All attempts resulted in the same error using GUI, even with matching platform and requirements:

To workaround the GUI error, you can create the ~/weblogic_forms_silent.rsp file and add the following with proper definition for your environment:

Response File Version=

#Set this to true if you wish to skip software updates

#My Oracle Support User Name

#My Oracle Support Password

#If the Software updates are already downloaded and available on your local system, then specify the path to the directory where these patches are available and set SPECIFY_DOWNLOAD_LOCATION to true

#Proxy Server Name to connect to My Oracle Support

#Proxy Server Port

#Proxy Server Username

#Proxy Server Password

#The oracle home location. This can be an existing Oracle Home or a new Oracle Home

#The federated oracle home locations. This should be an existing Oracle Home. Multiple values can be provided as comma seperated values

#Set this variable value to the Installation Type selected as either Standalone Forms Builder OR Forms and Reports Deployment
INSTALL_TYPE=Forms and Reports Deployment

#The jdk home location.

Ensure you have installed all prerequisites:

  • Weblogic – fmw_12.
  • FMW Infrastructure – fmw_12.

Now, if you try to install Oracle Forms (fmw_12. installer using the response file ~/weblogic_forms_silent.rsp:

[oracle@formslab]$ ./fmw_12. -silent -response ~/weblogic_forms_silent.rsp -invPtrLoc /oracle/middleware/oraInst.loc


The installation completes like a charm.
