System is not getting up after parameter changes

[Former Member]

Hi,

I had recently change some memory parameter in one of the test system. I increase the memory according to the requirement . Before extand heap memory I check ST02 buffer memory requirement and the recommendation but after the changes I found dispatcher not bringing up properly. still system is down.

On the fly I had revert back the changes as before, now system is up and running fine

but my concern is what should I do if this kind of issues are facing . this is not the solution to revert back the changes . how could I found the rout cause of this issue. and fix it.

we have enough memory and all are standard recommendation then why the system is not getting up

I check start and stop logs under the work directory and check div* logs but no any relevant information found.

Thanks

Sandeep

- copy and paste the error in dev_disp

- let us know what memory parameters and value that you changes to and revert back to

- list down all the current parameters from ST02 -> Current parameters

- your system SP level, Kernel version and patch level.

- your system landscape

- sappfpar check pf=< your instance profile>

Hello,

You can use the program sappfpar to checlk youe new profile.

You do your changes and activate the profile.

Then you do :

sappfpar -f check pf=full_path_to_your_instance_profile

You may have some warnings but if errors are shown you are sure that your instance will not start up.

BR,

Steve.
