OS/DB migration : Distribution Monitor nodes

[Former Member]

Hi All,

We are in the process of migrating our ECC 6.0 environmnet from Solaris + DB2 to AIX +DB2.

We are using Linix Application server as our Distribution Monitor nodes. In this run we did not get the result as per our expectation. Could please share your experinece or recomendation to use third OS (in our case Linux) for Distribution Monitor Node. Is there any recomendation or best practice for Distribution Monitor nodes -- whether we should use same OS as Source system or Traget OS or we can use any Application Server ( OS).

Regards,

Dipam Phukan

What were/are your expectations and what were the results?

It's very hard to guess what you have configured, how man nodes and processes you use, what parameters you used etc. Your question is too generic to give an advise.

Best Approach migrate your ecc 6.0 from solarisDB2 to AIXDB2

if you use migmon or Distubution method its take time . For DB2 migration we can go backup/restore method.

If you are system running on DB2 . you can move any unix to any unix with out using migtaion tools . you can use only backup restore mehtod.

You can use redirected restore to create a Heterogeneous system copy between 2 systems running on different platforms.

Compare to orace , DB2 lot of benefits . if same case required to move with oracle mean you need to migration but DB2 you can backup restore method.

Procedure:

1. use Redirect resore mehtod

2. source system preparation .

run redirect restoer script in source sytem

3. Target system preparation

install fresh system and resore the database from backup using redirect restore

Hello Dipam,

I recommend to use this tool if you have more than 5TB and you want to use all resource of you DB to export, in order to reduce export/import time. So, you can configure one or more servers to distribute process. In this case, I suggest use unix or linux server to share file systems.

If you have less than 5TB and your database server is good, I suggest to use Migration Monitor. You can export/import at least in 24hs.

Good luck!
