I am planning for building a new database server using AIX 6.1 and Oracle 11.2 using ASM.
As i have learned starting with Oracle 11.2 ASM can only be used in conjunction with Clusterware, which is Oracles HA-software. As is the companies policy we do intend to use PowerHA as HA-solution instead so that we will have these two HA-softwares running on the same system.
Searching the net i found indications that such a setup is possible*) and even certified*), but i nowhere found any information about how the interoperation of the two HA-software-packages is actually effected. Further I'd like to know if anybody has already done this and could share his/her experiences.
*) for instance: Oracle Database 11g Release 2 and Oracle RAC 11g Release 2 on IBM AIX - Tips and Considerations
or the Oracle MetaLink note 404474.1.
