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 server as oracle.
| No Format |
|---|
su - oracle |
2. The database orcl XE on both the source and target server should be started and available. To check if the database orcl XE 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 oraxe_pmon_orclXE oracle 2974 2933 0 13:35 pts/1 00:00:00 grep pmon |
If the oraxe_pmon_orcl XE process is running, that is a good indication that the Oracle database is running.
3. On the source server, check the TNS connection to the source database
