R3 library usage

[Former Member]

We have installed a high availability solution and I am in the process of trying to determine all the libraries and IFS objects I should be replicating. There are a couple of libraries on the system which I am not sure how they are really used or if they are just some leftovers from some maintenance or upgrade process in the past. Examples, R3QTEMP and GEN46DEOPT. I know different iseries customers are using various HA solutions but I would be interested if anyone could state what specific libraries and IFS links they are replicating for HA purposes.

Hi Russ,

R3QTEMP should be deleted and should never appear again as it was replaced by PCHsid a few years ago ...

I assume, you are using a 4.6D system ...

Then I would use the following:

- r3siddata

- r3sidjrn

- kernel lib

- r3sid400

- r3400

- r3sys

- r3wrk00

- /usr/sap/sid/sys/profile

(i would exclude the rest as it only creates problems with locking situations and batch jobs - at least you should exclude the batch job directories)

If you need more detailed descriptions, please let me know.
