Today I get the next error when I was importing an offline repository to the OMS (Version 12c);
Error: The command name "import_update_catalog" is not a recognized command. Run the "help" command for a list of recognized commands. You may also need to run the "sync" command to synchronize with the current OMS.
The command was;
./emcli import_update_catalog -file=/oracle/anr_donwloads/p9348486_112000_Generic.zip -omslocal
Like the error message show us, you need to execute a synchronize, but you need first log, as show below;
oms> ./emcli login -username='SYSMAN' Enter password : Login successful oms> ./emcli sync Synchronized successfully ### Reexecute the import command
