Applications • Oracle Plugin failed on connect to socket by IP

Hi all!

rman target /



run {

ALLOCATE CHANNEL VeeamAgentChannel1 DEVICE TYPE SBT_TAPE

PARMS 'SBT_LIBRARY=/opt/veeam/VeeamPluginforOracleRMAN/libOracleRMANPlugin.so'

FORMAT 'c5754297-69aa-4f13-98d5-c8280d8022f0/RMAN_%I_%d_%T_%U.vab';

}
