# Final Release Note If the replication instance file pointed to by [$ydb_repl_instance](https://docs.yottadb.com/AdminOpsGuide/basicops.html#ydb-repl-instance) / $gtm_repl_instance does not exist, [MUPIP RUNDOWN](https://docs.yottadb.com/AdminOpsGuide/dbmgmt.html#rundown) nevertheless attempts to rundown database files. Previously, it would raise a [REPLINSTACC](https://docs.yottadb.com/MessageRecovery/errors.html#replinstacc) error, and not rundown the database files. [#1154] # Description ```sh $ source /usr/library/V989_R203/pro/ydb_env_set $ mupip rundown -r '*' %YDB-E-REPLINSTACC, Error accessing replication instance file /home/sam/.yottadb/r989_x86_64/g/yottadb.repl %SYSTEM-E-ENO2, No such file or directory ``` If you unset gtm_repl_instance and ydb_repl_instance, it works successfully. ```sh $ unset gtm_repl_instance $ unset ydb_repl_instance $ mupip rundown -r '*' %YDB-I-MUFILRNDWNSUC, File /home/sam/.yottadb/r989_x86_64/g/yottadb.dat successfully rundown %YDB-I-MUFILRNDWNSUC, File /home/sam/.yottadb/r989_x86_64/g/%ydbaim.dat successfully rundown %YDB-I-MUFILRNDWNSUC, File /home/sam/.yottadb/r989_x86_64/g/%ydbocto.dat successfully rundown %YDB-I-MUFILRNDWNSUC, File /home/sam/.yottadb/r989_x86_64/g/%ydbjnlf.dat successfully rundown ``` # Draft Release Note When $ydb_repl_instance points to a location without a file, a mupip rundown command will still try to apply to the global directory. Below is an example to illustrate this. In this example, $ydb_repl_instance=/home/username/.yottadb/r985_aarch64/g/yottadb.repl but no file exists at that location. SHELL\> $ydb_dist/mupip rundown -r '\*' %YDB-W-FILENOTFND, File /home/username/.yottadb/r985_aarch64/g/yottadb.repl not found %SYSTEM-E-ENO2, No such file or directory %YDB-I-MUFILRNDWNSUC, File /home/username/.yottadb/r985_aarch64/g/yottadb.dat successfully rundown %YDB-I-MUFILRNDWNSUC, File /home/username/.yottadb/r985_aarch64/g/%ydbaim.dat successfully rundown %YDB-I-MUFILRNDWNSUC, File /home/username/.yottadb/r985_aarch64/g/%ydbocto.dat successfully rundown Previously, if $ydb_repl_instance did not point to a real file, that would cause an error and not continue execution. The 3 files from the example would not have been rundown.  Note, if ydb/gtm_repl_instance do not point to a replication file and you do not plan to use them in the future, consider unsetting the environment variables.
