rman target=sysop/password@targetdb catalog=rman/password@catdb log=rman.log append @rman.txtThe reason was that network was down and there was no connection to catdb. It leaded to error and RMAN did not start at all. So I’ve changed my command line to:
rman target=sysop/password@targetdb log=rman.log append @rman.txtAnd added a line in rman.txt
connect catalog rman/password@catdb;Next time there will be no connection to catdb backup will be done anyway. It will be not registered in catalog only. Catalog will be synchronized on next backup procedure or next time you connect to target and catalog an issue any command that operate on catalog.
