Target Database: Tibero
In all replications, source must be an Oracle database. Thus, two-way replication with Tibero is not supported.
For datatype mapping between Oracle and Tibero, please see Supported Datatypes.
For supported operating systems between Oracle and Tibero, please see Supported Platforms.
A Tibero client installation is required for the server that runs the setup wizard.
Server that runs MINE, APPLY and Replicate command console uses ODBC connection.
Operating System Setup
ODBC driver used on Linux platforms is unixODBC.

Oracle to Tibero Replcation Setup Example
Install Dbvisit Replicate software as root user
Login to server as tibero user
Run dbvrep command and start setup wizard
tibero@dbvlinuxbox[/home/tibero/TIBERO]: dbvrep Initializing......done Dbvisit Replicate version 2.9 Copyright (C) Dbvisit Software Limited. All rights reserved. No DDC file loaded. Run "setup wizard" to start the configuration wizard or try "help" to see all commands available. 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] Accept end-user license agreement? (View/Yes/No) [View] Yes Before starting the actual configuration, some basic information is needed. The DDC name and script path determines where all files created by the wizard go (and where to reread them if wizard is rerun) and the license key determines which options are available for this configuration. (DDC_NAME) - Please enter a name for this replication: [] TIB1 (LICENSE_KEY) - Please enter your license key: [(trial)] Which Replicate edition do you want to trial (LTD/XTD/MAX): [MAX] (SETUP_SCRIPT_PATH) - Please enter a directory for location of configuration scripts on this machine: [/home/tibero/TIB1] Network configuration files were detected on this system in these locations: /u01/app/oracle/product/12.1.0/db_1/network/admin (TNS_ADMIN) - Please enter TNS configuration directory for this machine: [/u01/app/oracle/product/12.1.0/db_1/network/admin] Step 1 - Describe databases ======================================== The first step is to describe databases used in the replication. There are usually two of them (source and target). Store SYSDBA and DBA passwords? Passwords only required during setup and initialization? (Yes/No) [Yes] Let's configure the database, describing its type, connectivity, user names etc. What type of database is this? (Oracle/MySQL/Google Cloud SQL/SQL Server/Tibero/Oracle AWS RDS/CSV/Hadoop): [Oracle] Please enter database TNS alias: [] SRCDB Please enter SYSDBA user name: [SYS] Please enter password for this user: [change_on_install] ******* Please enter user with DBA role: [SYSTEM] Please enter password for this user: [manager] Connecting to database SRCDB 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] dbvrep Please enter password for this user: [dbvpasswd] Permanent tablespaces detected in database: EXAMPLE, SOE, STREAMS_TBS, USERS. Please enter default permanent tablespace for this user: [EXAMPLE] USERS Temporary tablespaces detected in database: TEMP. Please enter default temporary tablespace for this user: [TEMP] Following databases are now configured: 1: Oracle SRCDB, SYS/***, SYSTEM/***, dbvrep/***, USERS/TEMP, dbvrep/, ASM:No, TZ: +00:00 Enter the number of the database to modify it, or "add", or "done": [add] Let's configure the database, describing its type, connectivity, user names etc. What type of database is this? (Oracle/MySQL/Google Cloud SQL/SQL Server/Tibero/Oracle AWS RDS/CSV/Hadoop): [Oracle] Tibero Please enter server name (as specified in tibero6/client/config/tbdsn.tbr: [localhost] dbvlin217.dbvisit.co.nz Please enter database ODBC DSN: [] tibero Please enter user name of an administrator: [SYS] Please enter password for this user: [password] ****** Enter the user to log into apply database: [DBVREP] Please enter password for this user: [password] Connecting to database tibero as SYS to query list of tablespaces. Permanent tablespaces detected in database: USR. Please enter default permanent tablespace for this user: [USR] Temporary tablespaces detected in database: TMP. Please enter default temporary tablespace for this user: [TMP] Following databases are now configured: 1: Oracle SRCDB, SYS/***, SYSTEM/***, dbvrep/***, USERS/TEMP, dbvrep/, ASM:No, TZ: +00:00 2: Tibero tibero, SYS/***, SYS/***, DBVREP/***, USR/TMP, /, ASM:n/a, TZ: Enter the number of the database to modify it, or "add", or "done": [done] 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: SRCDB (Oracle) 2: tibero (Tibero) (cannot be source, is not Oracle) Select source database: [1] Select target database: [2] Will limited DDL replication be enabled? (Yes/No) [Yes] Use fetcher to offload the mining to a different server? (Yes/No) [No] Should where clauses (and Event Streaming) include all columns, not just changed and PK? (Yes/No) [No] Would you like to encrypt the data across the network? (Yes/No) [No] Would you like to compress the data across the network? (Yes/No) [No] How long do you want to set the network timeouts. Recommended range between 60-300 seconds [60] Lock and copy the data initially one-by-one or at a single SCN? one-by-one : Lock tables one by one and capture SCN single-scn : One SCN for all tables ddl-only : Only DDL script for target objects resetlogs : Use SCN from last resetlogs operation (standby activation, rman incomplete recovery) no-lock : Do not lock tables. Captures previous SCN of oldest active transaction. Requires pre-requisite running of pre-all.sh script (one-by-one/single-scn/ddl-only/resetlogs/no-lock) [single-scn] What data instantiation script to create? ddl_file : DDL file created (APPLY.sql) ddl_run : DDL is automatically executed on target load : All replicated data is created and loaded automatically none (ddl_file/ddl_run/load/none) [ddl_file] load Do you want to (re-)create the tables on target or keep them (they are already created)? (create/keep) [keep] create Following replication pairs are now configured: 1: SRCDB (Oracle) ==> tibero (Tibero), DDL: Yes, fetcher: No, process suffix: (no suffix), compression: No, encryption: No, network timeout: 60, prepare type: single-scn, data load: load_create Enter number of replication pair to modify it, or "add", or "done": [done] 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: SRCDB (Oracle) ==> tibero (Tibero), DDL: Yes, suffix: (no suffix), prepare: single-scn No tables defined. Enter number of replication pair to modify it, or "done": [1] 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: [] SCOTT.EMP Selected tables: SCOTT.EMP Add more tables or schemas? (Yes/No) [No] You can also specify some advanced options: 1. Exclude some tables from schema-level replication 2. Rename schemas or tables. 3. Specify filtering conditions. 4. (Tables only) Configure Event Streaming; this does not maintain a copy of the source table, but logs all operations as separate entries. This is useful for ETL or as an audit trail. This usually requires adding of new columns (timestamps, old/new values etc.) to the target table. Specify rename name, filter condition or audit for any of the specified tables? (Yes/No) [No] Following tables are defined for replication pairs: 1: SRCDB (Oracle) ==> tibero (Tibero), DDL: Yes, suffix: (no suffix), prepare: single-scn SCOTT.EMP 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 SRCDB Not configured. 2: APPLY on tibero Not configured. Enter number of process to modify it, or "done": [1] Fully qualified name of the server for the process (usually co-located with the database, unless mine is offloaded using fetcher): [dbvlin217.dbvisit.co.nz] Server type (Windows/Linux/Unix): [Linux] Enable email notifications about problems? (Yes/No) [No] Enable SNMP traps/notifications about problems? (Yes/No) [No] Directory with DDC file and default where to create log files etc. (recommended: same as global setting, if possible)?

Before data replication can start, the target database must have a copy of the database objects that are going to be replicated. It is also highly desirable that the data in the objects to be replicated are also completely in sync. If the data is not in sync before replication starts, there is a strong possibility that data conflicts can occur. For instance if a record is updated or deleted on the source database that does not exist on the target database.
It is important that the replication starts at the same point as when the source and target data are in sync so that no changes are lost when replication starts. This is done through capturing the Oracle SCN (System Change Number) at the point the table is "prepared" in Dbvisit Replicate.
Only when the target database is Oracle, Dbvisit Replicate assists in creating and setting the starting point without any outage on the source database. But when the target database is not Oracle, then this will have to be done manually causing outage on the source database. Please note that when replication start, source and target objects must be in sync leaving no scope for conflicts in replication due to data divergence. Therefore in production environment, configuration of Dbvisit Replicate should be done when source database is idle. Therefore is desired to instantiate (ie. run the -all,sh) during a maintenance window when no one is accessing source application (schemas/tables) that are desired to be replicated to Tibero.
In addition to our LOAD function that is available for creating a starting point there are various tools available to load data from Oracle to Tibero like TBMigrator (see https://www.youtube.com/watch?v=12d4ciL3To4)
