EHP4 INstallation on ECC 6.0 EHP4 Ready - ABAP Only

Former Member

Dear Experts,

We are planning to install EHP4. I have some queries regarding the EHP4 installation.

Our Environment:

ECC Version: ECC 6.0 EHP4 Ready - ABAP Stack Only

Operating Sys: AIX 6

Database: Oracle 10.2.0.4

My Queries are:

1. What does the ECC 6.0 - EHP4 ready means & why we cannot use it without installing EHP4 on it?

2. Since at the time of ECC installation, we have selected only Web AS - ABAP, so is the NW-EHP1 installed on our system?

3. We have 3 DVDs of EHP4 & downloaded EHPinst via service market place download centre, so can I directly install EHP4 using the EHPinst & the 3 DVDs without downloading the SP Stack via MOpz (since our ECC is EHP4 ready, so it must be having latest Support Packs - my guess)?

4. In SolMan - SMSY , the relevant components selected against our ECC is only ECC server, due to which I am only able to select very few Technical Usage types in Solman - MOpz. Since, our ECC is only ABAP stack, so is it possible that in SolMan - SMSY, I select more relevant components against our ECC like - NW - Portal, NW - BI to be able to select the usage types of Portal Content & BI Content in SolMan - MOpz?

5. The installation guide says that aprox 100 GB free space is required for shadow system. My doubt is where is this 100 GB free space required? Do I need to create a new mount point of 100 GB OR do I need to add 100 GB space to sapdata1 - sapdata4 OR do I need 100 GB free space in my database tablespace?

6. Our /usr/sap/<SID> directory total size is 10 GB out of which 9 GB is free. Is this sufficient?

7. Our /usr/sap/trans directory total size is 20 GB out of which 17 GB is free. Is this sufficient?

8. Can I use a directory other than /usr/sap/<SID> as the EHPI installation directory, as I have an unsed mount point of 30 GB?

9. Are there any parameter changes required in SAP & Oracle before starting EHP4 installation?

10. Do we need to suspend background jobs before starting EHP4 installation?

11. Can I switch DB to noarchivelog mode before starting EHP4 installation?

12. Is there any post installtion steps to be performed after EHP4 installation or we can directly release the system to users?

Any other information/experiences you would like to share are most welcome.

Regards,

Ashish Khanduri

Hi,

It means that all basic netweaver components are on 701 release and all ERP components will be on 600 release. So, from here you can upgrade to ERP EHP4 components.

> 2. Since at the time of ECC installation, we have selected only Web AS - ABAP, so is the NW-EHP1 installed on our system?

Yes, you can check status of your netweaver components like SAP_Basis, SAP_ABA etc. and all will be on 701 release.

You should calculate your stack with MOPZ only. Because you also need stack xml file for upgrade which you will get from MOPZ only.

Since your system is based upon ABAP only so you cannot select any usage type in which Java is there like Portal etc.

And you should select only usage type that you will be using in your ERP system. If you will select a number of usage type then it will make any sense as upgrade will take a lot of time to upgrade.

You need this 100 GB of temporary space in existing sapdata's mount point only.

Yes.

> 7. Our /usr/sap/trans directory total size is 20 GB out of which 17 GB is free. Is this sufficient?

You need to check where you will make the upgrade directory and download directory and accordingly you need more space.

> 8. Can I use a directory other than /usr/sap/<SID> as the EHPI installation directory, as I have an unsed mount point of 30 >GB?

Yes, you can use it.

> 9. Are there any parameter changes required in SAP & Oracle before starting EHP4 installation?

>

You should adjust your oracle database parameters as per SAP note 830576 to optimize the upgrade. Also during upgrade choose sufficient number of R3trans and background processes so that upgrade will not take long runtime.

> 10. Do we need to suspend background jobs before starting EHP4 installation?

>

You need not to do anything

> 11. Can I switch DB to noarchivelog mode before starting EHP4 installation?

Its depends upon resources in your system. Also, if your system is productive then archive should be on till downtime phase. But as I can understand that you are doing fresh installation then you can switch off the archiving to get better performance

.

>

Yes you need to perform few post-installation steps that is mentioned in the upgrade guide.

>

All important things are mentioned in the upgrade guide. Please read upgrade guide.
