System not start after shutdown past EHP7

[Former Member]

Hello Gurus,

we had successful EHP7 installed in our DEV system.

After that we need to change some parameter for roll area and restart the system.

But it do not start and we can't find any log with information.

We have roll back the changes in the profile, but no change.

Has someone a suggestion?

Hi,

we found another profile parameter file in backup.

After compare with the actual we could see, that the other are merged with start profile parameter file from SUM.

With this one, the system is starting.

Thanks.

We'll search for more information about kernel and profile changes with 7.4 and check our profiles.

[EDIT] It seems that RZ10 do cut off the start parameter of parameter file?!

First check the trace files in the /usr/sap/E11/SCS<NN>/work directory.

Try restarting the instance after removing the stream files in the /tmp

If the system fails to start then check the trace files in the work directory of the SCS instance.

Hi,

we have no SCS.

This is a old installation.

What I meant is ASCS. I am very sure if you upgrade an old system to EHP7, after the upgrade you will have ASCS.

[Former Member]

nope. There is no ASCS after update.

Do we have roll area in 7.4X ?

2085980 - New features in memory management as of Kernel Release 7.40

What is that parameter that you have changed ?

Can you share the logs from work directory, please ?

Hi,

we removed parameters

em/global_area_MB = 256

em/initial_size_MB = 2000

em/max_size_MB = 2000

but if we changed back, it also do not start.

The picture shows all written logs. Only 7.

Three are attached at last post. Here are all.

Hi Christian,

Thanks for the reply.

Can you alos check and give us the logs from ASCS work directory ?

Also, have you un-mounted /proc on a file system in AIX ?

If all is fine above, then please cross check "E11_DVEBMGS00_sape11" profile.
