Logical replication using Dbvisit Replicate is configured using a setup wizard. The setup wizard does not make any database changes, instead it creates a set of configuration scripts that can be inspected before executing to give full visibility of database changes.
...
| Note |
|---|
Please ensure the following prePre-requisites checks have been tested. Otherwise the replication will not function. |
...
The following is a step-by-step guide of configuring a replication using the setup wizard. To accept the default answer for a question, just press the Return key.
1. Connect to On the source server server, as oracle.

2. In the home directory of oracle , in the $HOME directory, execute the dbvrep executable to start Dbvisit Replicate.

dbvrep> setup wizard
This wizard configures Dbvisit Replicate.
The setup wizard creates configuration scripts, which need to be run after the wizard ends. No changes to the databases are made before that.
The progress is saved every time a list of databases, replications, etc. is shown. It will be re-read if wizard is restarted and the same DDC name and script path is selected.
Run the wizard now? [yes] yes

Enter the location where Dbvisit Replicate will find the Oracle network configuration files.

Let's configure the database, describing it's type, connectivity, user names etc. What type of database is this? (Oracle/MySQL/SQL Server/Oracle AWS RDS/CSV/Hadoop): [Oracle] |
6. The TNS alias is sourcefor the source database is ttorcl_src
| No Format |
|---|
Please enter database TNS alias: [] sourcettorcl_src |
Enter the username and password of a user with SYSDBA. Accept the default of SYS and change_on_install.
...

Connecting to database sourcettorcl_src as SYSTEM to query list of tablespaces and to detect ASM (by looking whether any redo logs or archived logs are stored in ASM). Enter the Dbvisit Replicate owner (this user will be created by this script): [dbvrep] Please enter password for this user: [dbvpasswd] |
...

Following databases are now configured: 1: Oracle sourcettorcl_src, SYS/***, SYSTEM/***, dbvrep/***, USERS/TEMP, dbvrep/, ASM:NO, TZ: +00:00 |

Step 2 - Replication pairs ======================================== The second step is to set source and targets for each replication pair. Let's configure the replication pair, selecting source and target. Following databases are described: 1: sourcettorcl_src (Oracle) 2: targetttorcl_trg (Oracle) Select source database: [1] Select target database: [2] |
...
| No Format |
|---|
Step 3 - Replicated tables ======================================== The third step is to choose the schemas and tables to be replicated. If the databases are reachable, the tables are checked for existence, datatype support, etc., schemas are queried for tables. Note that all messages are merely hints/warnings and may be ignored if issues are rectified before the scripts are actually executed. Following tables are defined for replication pairs: 1: sourcettorcl_src (Oracle) ==> targetttorcl_trg (Oracle), DDL: yes, suffix: (no suffix), prepare: single-scn No tables defined. Enter number of replication pair to modify it, or "done": [1] |
18. Add Specify the REPOE schema is to be replicated.
| No Format |
|---|
Please enter list of all individual tables to be replicated. Enter schema name(s) only to replicate all tables in that schema. Use comma or space to delimit the entries. Enter the tables and schemas: [] repoe Selected schemas: REPOE |

Following tables are defined for replication pairs: 1: sourcettorcl_src (Oracle) ==> targetttorcl_trg (Oracle), DDL: yes, suffix: (no suffix), prepare: single-scn REPOE(tables) Enter number of replication pair to modify it, or "done": [done] |
...

|---|
Step 4 - Process configuration ======================================== The fourth step is to configure the replication processes for each replication. Following processes are defined: 1: MINE on sourcettorcl_src Not configured. 2: APPLY on targetttorcl_trg Not configured. Enter number of process to modify it, or "done": [1] |
...
| No Format |
|---|
Following processes are defined: 1: MINE on sourcettorlc_src Host: source, SMTP: no, SNMP: no 2: APPLY on targetttorcl_trg Not configured. Enter number of process to modify it, or "done": [2] |
...

Following processes are defined: 1: MINE on sourcettorcl_src Host: source, SMTP: no, SNMP: no 2: APPLY on targetttorcl_trg Host: target, SMTP: no, SNMP: no Enter number of process to modify it, or "done": [done] |
