aix 5.3的服务器该淘汰了,如果要保持原有应用不变,请问有什么好的解决办法?

我们这里有2台p550 +aix5.3+oracle9i 组成的双机,随着时间的推移,这套生产系统也将走向末端。想继续使用aix 5.3+oracle9i,因为小机里有oracle 开发的程序,不想改变环境,否则太复杂。还有什么好办法搭建这样的环境?...显示全部

如果你的版本是最新的5300-12-09,应该还能在power8上使用,但是需要一个power8的兼容补丁,而且有挺多限制。。。
The PTF enables 5.3 TL12 support with the following limitations:

· The LPAR must be at AIX 5.3 TL12 SP9 (latest 5.3 release).

· The Power8 LPAR will run in Power6 compatibility mode and is limited to SMT2 mode, which is the natural operating mode for AIX 5.3. Power8 servers can support SMT4 and SMT8 modes as well that are available to more current AIX releases. IBM publishes SMT2 rPerf values that can be used to quantify Power8 SMT2 capacity

· 5.3 Power8 LPARs only support Virtual I/O configurations: vSCSI , NPIV, VLAN. AIX 5.3 does not support 4K sector size storage. Any storage virtualized to 5.3 LPARs must use 512 byte sectors.

· Power8 systems support a minimum entitlement of 0.05 physical processor units per VCPU (virtual processor). AIX 5.3 requires 0.1 physical processor units per virtual processor. If a 5.3 Power8 LPAR does not have sufficient entitlement, it will fail to start.

· 5.3 LPARs support a 64 VCPU maximum. Power8 systems allow LPARs with larger VCPU configurations. If more than 64 VCPUs are assigned to a 5.3 LPAR, it will fail to start.

Only 5.3 Power8 installation methods are supported:

· mksysb – First perform an in place update to a supported (P5/P6/P7) 5.3 TL12 SP9 LPAR with PTF U866665. Standard mksysb command can then be used to capture a P8-capable mksysb image. The mksysb image can then be used to install Power8 LPARs.

· NIM – A 5.3 TL12 SP9 NIM environment must be updated to support Power8. A 5.3 TL12 SP9 NIM lpp_source must be updated to include PTF U866665. A NIM SPOT must then be created or updated to utilize the updated lpp_source .

· LPM – First perform an in place update to a supported (P6/P7 ) 5.3 TL12 SP9 LPAR with PTF U866665. The update is not concurrent so an LPAR restart is required. Once the LPAR has been restarted, LPM can be used to migrate to a Power8 system. The P6/P7 LPM source must use VIOS 2.2.2.70/2.2.3.50/2.2.4.10 (or later) and any supported firmware level.

All Power8 systems are supported with the following restrictions:

· Power8 system must be at 840 firmware level

· Power8 LPAR must be served by a 2.2.4.10 or 2.2.3.60 VIOS

Other restrictions:

· Remote restart is not supported with Power8 5.3 LPARs

· Power8 5.3 LPARs are not supported with a VIOS using Shared Storage Pools.
