ERROR at line 1: 
ORA-01722: invalid number

Cause

Instance has not started with UPGRADE ( MIGRATE for 9.2) mode , which caused catupgrd.sql failed execute.

There can be multiple cause for the ORA-01722 error. Following are few listed

1. Database not started as UPGRADE or MIGRATE Mode.
2. SQL*PLUS session user running this script is not SYS.
3. Database server version is not correct for this script.
4. If the SYSAUX tablespace does not exist or is not ONLINE for READ WRITE, PERMANENT, EXTENT MANAGEMENT LOCAL, andSEGMENT SPACE MANAGEMENT AUTO.[Applicable Only For 10G]

Solution

1. Ensure you have followed the following criteria

Database as UPGRADE or MIGRATE Mode.
Logged on as SYS user when running this script.
Database server version matches for this script i.e catupgrd.sql for 10.2 need to be executed for 10.2 database
If the SYSAUX tablespace exist and is ONLINE for READ WRITE, PERMANENT, EXTENT MANAGEMENT LOCAL and SEGMENT SPACE MANAGEMENT AUTO.[Applicable Only For 10G]

2. If you are meeting above criteria , then open the script from appropriate location %ORACLE_HOME%/rdbms/admin

3. Goto the SQL command which fails with error i.e in this case
SELECT TO_NUMBER('MUST_BE_OPEN_UPGRADE') FROM v$instance
and check you have performed the criteria mentioned above SQL command

While running the catbkout .sqlor catupgr.sql , you will also see the following appear on console . These are comments before SQL , which are for information purpose.
