Multiple SAP systems on a Single LPAR

Hi Gurus,
We are planning to install ECC, BW, SRM, PI, EP, SolMan, NWDI on one LPAR on IBM i6.1 OS. I came to know that this is the common practice of installing SAP on IBM iseries.
Do I need to review for any dependencies or the technical limitations?
Obviously, the DB2 instance will be the same for all these systems and will be a MCOD solution.
If you have done any recent installations on IBM iseries, please let me know the lessons learned.
Thanks
Kalyan

Hi my friend
No problem to have multiple instances installed in one LPAR, like you said it's the common way to place your non-prod environment. Just make sure that OS level parameters of AS/400 are well tuned for this many instances running together from performance perspective, use IT4J JVM for AS Java instead of classic JVM. Here's some FYI:
Note 484548 - iSeries: 3 tier system installation
Note 192658 - Setting parameters for BW systems
Note 541508 - iSeries: Checking the system parameters for BW
Note 307077 - iSeries: Performance optimization for BW systems
Note: installing multiple instances in one LPAR doesn't mean it's a MCOD installation. They still have their own DB library, known as database on other platforms. In the case of MCOD, all instances will use the same DB library as database instance.
Regards,
Effan
