geode: "create region" is not available. Reason: Requires connection

Question

I've followed the instructions on https://cwiki.apache.org/confluence/display/GEODE/Index#Index-Geodein5minutes an started a locator and a server. When I try to create a region, I get an error message: ""create region" is not available. Reason: Requires connection.".

Could you please help me with a solution ?

I'm running my locator, my server and the region in 3 separate windows.

OS: Windows7-64bit
Java: build 1.8.0_25-b18

Last entry in locator.log: [info 2015/09/30 17:16:51.703 CEST locator tid=0x51] Cluster configuration service start up completed successfully and is now running ....

The reason you're not seeing the same results as described in Geodein5minutes is that you're using three separate windows. Geodein5minutes describes using one single window.

Below shows going through Geodein5minutes with a couple extra commands such as "list members" and "list region" to illustrate.

After I started the locator, I typed "list members" which shows that GFSH autoconnected to the locator I just started. In the same GFSH window, I then proceed to start the server.

If you want to use separate GFSH windows you can, but you'll need to use the connect command in the other windows.

I need to use separate windows, because after "start locator --name=locator" I do not get my prompt back. All I see is "Starting a GemFire Locator in ........................................." — Stefan Lecho, Oct 02 '15 at 06:09
That was a bug that was fixed in GemFire 8.2 and Apache Geode. GFSH consumes the stdout/stderr of the launched process, but calls to BufferedReader.readLine() will block on Windows until the process departs. We changed it to be non-blocking. Try it in GemFire 8.2 or with Geode and you'll see it correctly return to the prompt. — Kirk Lund, Oct 02 '15 at 16:01
Was this fixed recently, because I did a git clone of https://github.com/apache/incubator-geode/ last Wednesday ? — Stefan Lecho, Oct 05 '15 at 07:16
I am using `gfsh>start locator --name=locator1`.. the prompt doesn't come back... I don't see any further movement in the log file either. — Divs, Jul 05 '17 at 11:56

When gfsh starts, you have to point it to a running locator using the connect command, so that you can create regions etc. The following is an example:

gfsh>connect --locator=localhost[10334]

This helps, but now I'm having another issue when creating a region: "No caching members found". BTW: it might be interesting to add this required step on https://cwiki.apache.org/confluence/display/GEODE/Index#Index-Geodein5minutes – Stefan Lecho Oct 01 '15 at 06:20

What is the output when you do "list members" in gfsh. gfsh>connect --locator=localhost[10334] list members

are the locator and server are in same host?

"list members": I only see the locator. locator and server are indeed running on the same host – Stefan Lecho Oct 01 '15 at 14:09
