The following describes new functions added to Tibero 6 FixSet03.
The following functions have been added.
TAC
Message communication can be made between TBCM and MTHR via the watchdog channel.
Added the V$INTERCONNECTION view that shows INC information about connections between TAC clusters.
Added the CR Request Async Service (CRAS) and Buffer Request Async Service (BRAS) threads.
| Thread | Description |
|---|---|
| CRAS | When another node in TAC requests building CR blocks, the building can fail. In this case, the CRAS thread is used to wait until the building is possible and to reattempt the building. |
| BRAS | If a block header (bh) was insufficient in TAC when caching blocks received along with messages from another node, CMPT (RCVR) continuously tried to allocate bh with blocking. Now the BRAS thread is used to allocate bh. If the allocation is successful, the bh is included in a message and CMPT can operate again. |
