File system /usr/sap/hostctrl/work getting full rapidly

[Former Member]

Dears,

Recently We have installed PI 7.1 on AIX 6.1 and database is Oracle 10g.

Everything is working fine but we are facing one strange issue with it.

Our file system /usr/sap/hostctrl/work is getting full again and again,I checked that there is a file dev_saphostexec that is taking maximum space,At present its of 15 GB.

So please suggest how to solve this problem.

Hi

Upgrading your host agent to the latest version available on the SMP under the following location should fix that issue:

The patch is available from:

service.sap.com/swdc -> Download -> Support Packages and Patches ->

Entry by Application Group -> Additional Components -> SAP Kernel -> SAP

KERNEL 64-BIT/32BIT -> SAP KERNEL 7.10 -> <Platform> -> #Database

independent -> SAPHOSTAGENT<Patch Level>.SAR.

To perform the upgrade proceed as follows:

- Ensure that all hostagent processes (saphostexec, sapstartsrv, saposcol) are terminated

- Extract the archive into a temporary directory

- Change to that directory and execute:

./saphostexec -upgrade

- This ugrades and restarts the host agent

Dear Mark,

I have read OSS Note SAP Note 1031096 - Installing Package SAPHOSTAGENT.

We are starting this week installing "Diagnostics Agent 711" on all SAP Netweaver 7.00 mananged system.

I have read the "Diagnostics Agent 7.11- Setup Guide".

In the "Installation Process", there is a step concerning the "Install the SAP Host Agent - Page 9".

I have read the "Installation_SAPHOSTAGENT.pdf" guide.

In the first page of this guide, it is written :

"You only need to download and install the host agent in the following cases :

- You want to centrally monitor a host that does not have an SAP component"

- You want to perform an upgrade to the SAP NetWeaver 7.1 for an SAP NetWeaver component".

In our productive envronment, we do have 2 clusters :

Cluster 01 is composed of 2 nodes.

Only "Databases" and "Central Services" of 5 SAP Systems are running.

There is no CI or SA

Cluster 02 is composed of 6 nodes.

Only CI and AS of 5 productive systems are running on theses 6 nodes.

My question :

Do we have to install a SAP HOST AGENT in nodes of cluster 01 ?

As written in "Downloading and Installating Package SAPHOSTAGENT" guide,

SAP HOST AGENT only need to be install on "host that does not have an SAP component".

Can we consider that "database" and "Central Service" are SAP Component or not ?

Thanks in advance for your feedback

Best regards

P. Cuennet
