Workaround or Resolution

For all but Linux, apply one of the operating system patches listed in the Patch section below.
For Linux, following the workaround below first described in Bug:4959183 "ORA-1019 Starting RQ on AIX or HP in Oracle 10g":
1. Copy the NLS files from an Oracle 9i instance into a directory on the Oracle 10g instance
The Oracle 9i NLS files are located in the following directory:
/<ORACLE 9i HOME>/ocommon/nls/admin/data
Important: Do not replace / overwrite the 10g NLS files.  Simply add the 9i files to a separate directory.
2. Edit the ORA_NLS33 entry in the "rq" or "mrq" script to point to the 9i NLS files
The rq and mrq scripts are located in: $OFSA_HOME/bin
Edit the following section to point to the 9i NLS files:
if [ -f /<OFSA Home>/ocommon/nls/admin/data/lx00001.nlb ]; then
      #  on some platforms NLS files not included yet 11/14/00
     ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data; export ORA_NLS33
fi
(where $ORACLE_HOME is the Oracle 10g home directory that contains the Oracle 9i library files )

Note:  If the error continues to occur after making the change listed above, remove the "if/then" statement and use a direct assignment of the ORA_NLS33 environment variable. For example:

Replace this:

if [ -f /<OFSA Home>/ocommon/nls/admin/data/lx00001.nlb ]; then
     # on some platforms NLS files not included yet 11/14/00
     ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data; export ORA_NLS33
fi

With this:

ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data; export ORA_NLS33
