The replication on both servers has now been started and the data will be kept in sync.
Data divergence
Currently Dbvisit Replicate does not offer a tool to monitor or detect data divergence or to bring the data back in sync should data divergence occur.
However Dbvisit Replicate offers very robust and complete notification. This can be configured according to specific thresholds to ensure the replication does not fall behind too far where the data divergence becomes unmanageable.
In future Dbvisit Replicate may include a tool to detect and manage data divergence.
House keeping
Dbvisit Replicate offers automatic house keeping on the following files:
• Dbvisit Replicate plog files. These will get removed on source and target systems once they are no longer needed.
• Dbvisit Replicate log files. These are set managed to keep one backup file and a size limit of 100MB.
This is configurable through the parameters:
◦ LOG_FILE_SIZE
◦ LOG_FILE_COUNT
◦ LOG_FILE_DATE_ROTATE
Manual house keeping is required on the following files:
• Dbvisit Replicate trace files
• Dbvisit Replicate Cache files (see below)
Dbvisit Replicate Cache files
The Dbvisit Replicate executable (dbvrep) is a self contained executable and contains all the necessary required libraries for it to function. These libraries are extracted out of the executable and into the default temporary directory of the system at startup of dbvrep. Dbvisit Replicate will reuse these cache files the next time that it is started. This maybe noticeable in the startup time of dbvrep. If the cache already exists, the startup time is faster.
It maybe possible that there are several cache directories. This can happen if a new version of Dbvisit
Replicate is installed. The old cache directories can be removed, however when dbvrep is running, it is difficult to determine which is the current cache and which is the old cache. If the cache needs to be removed, then is preferable to shutdown dbvrep and then remove all cache files and then to restart dbvrep.
The cache files are in the OS default temp directory under a directory called par-username.
