Method Detail

trySTF
```
public static void trySTF(AltibaseFailoverContext aContext,
                          java.sql.SQLException aException)
                   throws java.sql.SQLException
```
STF를 시도하고, 결과에 따라 예외를 던진다. 성공했을때도 예외를 던져 STF 성공을 알린다.
만약 failover context가 초기화되지 않았다면 원래 났던 예외를 던지거나 사용자가 넘긴 경고 객체를 그대로 반환한다.

Parameters:

aContext - Failover context

aException - 원래 났던 예외

Throws:

java.sql.SQLException - STF에 실패했다면 원래 났던 예외, 아니면 STF 성공을 알리는 예외

doCTF

public static boolean doCTF(AltibaseFailoverContext aContext,
                            AltibaseFailover.FailoverType aFailoverType,
                            AltibaseFailoverServerInfo aNewServerInfo)

shard failover align을 할때 수행되며 특정 서버로 CTF를 시도한다.

Parameters:: aContext - Failover context 객체; aFailoverType - Failover 타입; aNewServerInfo - 접속할 서버
Returns:: aNewServerInfo 서버로의 CTF 성공여부

connectToAlternateServer

public static boolean connectToAlternateServer(AltibaseFailoverContext aContext,
                                               AltibaseFailover.FailoverType aFailoverType,
                                               AltibaseProperties aProp,
                                               AltibaseFailoverServerInfo aNewServerInfo)

isNeedToFailover
```
public static boolean isNeedToFailover(java.sql.SQLException aException)
```
Failover가 필요한 예외인지 확인한다.

Parameters:

aException - Failover가 필요한지 볼 예외

Returns:

Failover가 필요하면 true, 아니면 false
