ORA-07217: sltln: environment variable cannot be evaluated

I got ” ORA-07217: sltln: environment variable cannot be evaluated ” error in Oracle database during catalog files.

 

ORA-07217: sltln: environment variable cannot be evaluated

 

Details of error are as follows.

RMAN> catalog start with '/backup/datafiles';

searching for all files that match the pattern /backup/datafiles

ORA-07217: sltln: environment variable cannot be evaluated.

RMAN>


 

The ORA-07217  error is related with the one of the database files. Database File name with $ sign as part of the name.  ‘<PATH>/<XXX$_XXXXX.dbf’.

Remove the unrelated files under Catalog directory.

Oracle is trying to evaluate a part of the datafile name as an environment variable rather than as part of the filename.

To solve this error, Rename the database file without using OS environment variables in the file name.

 

If you got this error on DDBOOST, you should apply the following actions.

In the environment the ORACLE_HOME is not set and the channel allocation was to handle it. It was determined that
when the tape channel completed the backup and deallocated the $ORACLE_HOME env variable so it could no longer be translated to complete the disk backup.

This is a vendor issue DDBOOST development have been alerted to the issue
and are working on a solution at the time of writing this note.

Note:  If you feel you are facing this issue please contact EMC support for a solution.

 

Workaround:

1. Enable BACKUP_TAPE_IO_SLAVES=TRUE

or

Split the scripts so the tape backup runs to completion and then the disk backup script is called after.

Note: We will update this note with the EMC Doc ID once it becomes available.
