SAS Cache locator service is not starting

[sandeep_reddy]

Hi There,

I am not able to start the cache locator service. While checking the gemfire command.log file i have seen as below

[info 2017/08/31 11:52:12.271 AEST <main> tid=0x1] Locator stopped

[severe 2017/08/31 11:52:12.271 AEST <main> tid=0x1] Could not bind locator to null[41,415]

In all the configuration files i have checked for DNS names,every thing looks fine. 

Can someone please help me in starting this service.

Thanks & Regards,

Sandeep

I know little about gemfire, so just some things I've picked up over time....

1.) After you've stopped it using the sas.servers script

- Check that no gemfire processes are running (ps -ef | grep gemfire | grep -v grep) for UNIX. Kill if there are.

- Delete the gemfire state file

What do mean exactly by: Delete the gemfire state file

Is it a rename of all files under .../Web/gemfire/instances/ins_41415/ will be Ok ?

You would not want to rename all the files there. There is a file called "locator41415state.dat" which I suspect is the state file being referenced here.

Hi,

looks like there is a process already running on 41415, meaning, the port is already used.

Can you check this?

Thanks

Hi All,
I don't know what went wrong. I have found .locator file as hidden file , I have deleted this file and restarted the sevices . Now Cache locator service came up.

Hi @sandeep_reddy,

I have the same situation, could you please advice me where the hidden file is located?

A quick

find /sasconf -name .locator

found me

/sasconf/Lev1/Web/gemfire/instances/ins_41415/.locator

[MariaD]

Thanks! So, after I deleted this file, I can start the cache service locator without any problem, right?

Try it.

I can't tell you more, as I have never experienced tese problems, and if it didn't start until now, what bad can happen?

Thanks. I had this issue after doing a system image restore in WinSvr2012r2.

@sandeep_reddy - Much appreciated. I had exactly the same problem and your solution fixed it.

Hello eb,

Even though solution work, problem repeats itself. So if specified files are deleted then it starts again. But real issue is how to prevent these problem iterating.  So any idea or real solution.

Hi,

I have the same issue, but there is no .locator file on my server. I have checked if it might be hidden but found out that it does not exist. Is there anyone have a suggestion for what should I do to fix this error and then be able to start SAS cache locator service?

[gwootton]

did you confirm no other process was listening on the gemfire port (41415)?
