REP-3000: Internal error starting Oracle Toolkit.

Solution:

1. Unset the following environment variables which are required by Forms, but in some circumstances can cause problems for Reports. Reset the variables before either running the Forms builder or compiling forms manually:

unset EVENT_10932
unset DE_DISABLE_PLS_512

2. Open $ORACLE_HOME/bin/reports.sh in a text editor and comment out the following lines.

TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1; export NLS_LANG

This modification is needed because these variables were set when the Applications OracleAS 10.1.2 environment was sourced, so must not be overwritten by the script. This problem will be fixed in OracleAS 10.1.2.3, when the Reports script will be modified to set the variables only when not already defined in the calling environment (as done for the frmbld.sh script).

3. Launch the builder by running the following script.

rwbuilder.sh
