Check the following pre-requisites before starting Dbvisit Replicate. If these are not correct, then the replication will NOT function.
1. Connect to the source (dbv01) server as oracle.
| No Format |
|---|
su - oracle |
2. The database orcl on both the source and target server should be started and available. To check if database orcl is running, check the pmon process (on both source and target)
| No Format |
|---|
$ ps -ef | grep pmon
oracle 2467 1 0 13:31 ? 00:00:00 ora_pmon_orcl
oracle 2974 2933 0 13:35 pts/1 00:00:00 grep pmon |
If the ora_pmon_orcl process is running, that is a good indication that the Oracle database is running.
23. On the source server, check the TNS connection to the source database
