When running a project for upgrading forms in PITSS.CON such as the project to replace the text_io function with webutil.client_text_io, if you happen to encounter the following error:

Search&Replace Error : ORA-06550: line 1, column 7:

PLS-00306: wrong number or types of arguments in call to ‘SYNCRN’

ORA-06550: line 1, column 7:

PL/SQL: Statement ignored.


There is a possibility that you might have encountered a bug with the Oracle Database especially if the database version is It has also been noted that this error also happens when you attempt to delete a form from Module Handling. There are two solutions which can be done to fix the problem:

1. Apply Oracle Patch 17501296 to the Oracle Database (version only). More information is provided in Oracle Support note 1586704.1.

2. Re-create the CTXSYS.SYNCRN procedure. The full SQL commands can be found in Oracle Support note 1586704.1.

After applying either one of the two solutions, the problem should no longer occur.
