SAP Instance Timing out.

[former_member624966]

Dear Expert,

I installed SAP Instance DEV on Azure cloud environment and below is the method of the installation.

It was a migration of on promise system land scape to Azure cloud Environment, I took the backup on-premise to the cloud, and restore Back database to the MSSQL 2008 R2 on the cloud after which i lunch the SWPM and i did a system copy and after that i perform all the necessary post installation activity, i created all the functional consultant on the system but after sometime, they started complaining that the system is timing out. which i confirm that is true. and i have tune the system, increase the buffer size and all other necessary thing that i thought could course system time out, but the issue still persist.

The system is running on OS Window server 2012 R2, database MSSQL 2008 R2.. i will glad if anyone have a solution for this issue.

Hi Ezeh,

1. How your functional consultants connecting to the cloud dev system?

2. Since it is on cloud the bandwidth between on promise to cloud (Internet connection) is this bottle nick?

Hi Ezeh,

Try to ping the remote SAP hosts check the network latency or if possible check the NIPing tool

Hi kannydan,

Do you have some peak time when this sort of issues happen, How many concurrent users do you have at the peak hours. Could you check if you have already some jobs capturing the memory

You can check via task manager CPU processes & utilization.

What T-shirt sizing did you take for your system, would like to know about the Processor specially that you took. Microsoft Azure provides some standard T-shirt sizes as per your resource & source system. Were you able to get a free sizing report from Microsoft before the migration to Azure, what does that sizing report say

How much is your target system RAM/CPU-cores & DB-size

What is the available swap memory & free memory in peak time

Were you able to check the details in SM21 logs or ST03N. If you have logon groups, you might want to reassign those logon groups

About you Azure resource utilization, that can also be checked in graphical view in your Microsoft-Azure dashboard.

You might want to check by changing your backup schedules, had a previous experience myself where we had all Dev/QA backups on Azure trigerred at the same time

Please check the top utilizing CPU processes & maybe you can also check via My Computer -->right click --> Manage --> Event viewer & Application logs

Please do let us know the details in case you still face issue

Thanks,

Kaushik

Increasing the buffer size is not going to help you with time out issues. Are there any TIME_OUT dumps appearing in the system? Check Tx ST22 and also look into the system logs (Tx SM21) when the time out appears. If the users connections are getting terminated while users are working then I suspect a network issue.

Hello Reagan,

Yes you are correct the issue have been narrow down to be network issue. The network team are already working to find a permanent solution to the issue. Thanks Everyone for your contribution.
