The purpose of this upgrade, is to take advantage of BI export library 2.0 which is provided particularly in Netweaver 7.01 release for BEx broadcaster printing since ADS is not supported on AS/400.

Source system SPs and kernel patch

Source system database is 100GB, locates in a LPAR which has 0.8 physical CPU allocated. The entire upgrade process took about 8 hours, detailed phases below:

Preliminary tasks (load new kernel, prepare upgrade directory): 1hour;

Preprocessing: 5hours, in this case it might have some lock wait situation and

performance conflict with backup process;

Downtime upgrade: 1.5hours

Post processing: 20mins, not include another 2-4hours system compiling.

Afterwards, data growth is less than 5GB.

 

Upgrade steps:

1.    Turn off MIMIX IFS replication, clear library MIMIX_A (if applicable)

2.    Download EHPi from SWDC: Support Packages and Patches - Entry by Application

Note: version 17 requires TP version 372.04.81 or higher, make sure you have it ready before preprocessing. Additionally, 701 kernel is compatible for 700 instances but for upgrade process only (refer to note 1284805), so it's safe and convenient to <br />apply latest 701 kernel library before starting the actual upgrade.)

18.  Preprocessing finished, now has reached downtime  phase, backup all journal

receivers and delete them

19.  In phase postprocessing, it reminds you to re-enable scheduled batch jobs which

are suspended by upgrade process by report  BTCTRNS2.
