3. Known Issues
Support for Oracle SE2HA (Standard Edition2 High Availability) will be available only from the next release.
Graceful Switchover with SQL Server InMemory tables is not supported.
Multiple standby databases for SQL Server are not supported in the current release.
Dbvisit Standby currently only supports ipv4, not ipv6.
Dbvisit Standby includes Oracle 12.2 Instant Client libraries by default. If your system has a different version of Oracle installed, it is possible under some rare circumstances for a library version conflict to occur. If you experience any errors similar to "PRKN-1008: Unable to load the shared library orasrvmhas12.dll", you can usually resolve them easily by renaming this library in the dbvisit/standby folder to "orasrvmhas12.dll.12.2" or by using replacing the Instant Client libraries in $DBVISIT_BASE/standbymp/oracle or $DBVISIT_BASEdbvisit/standbymp/oracle/lib (depending on your operating system).
