Support for SQL Anywhere 11.0 mirroring (IM) – PB Docs 2022

PowerBuilder 11.5.1 allows you to take advantage of SQL Anywhere
11.0 database mirroring. Database mirroring is a configuration of either
two or three database servers that cooperate to maintain copies of
database and transaction log files. If the primary server becomes
unavailable because of hardware or software failure, the mirror server
negotiates with the SQL Anywhere arbiter server to take ownership of the
database and assume the role of primary server.
