Visual Admin - JCo RFC failure

[Former Member]

Hi,

We are getting below error when using Visual administrator -> cluster> server0> services-> Destination

RFC destination created causing error when save & test.We are trying to use load balancing using message server, within company network.

We have one CI and 2 app servers.

Interestingly, this error happens only in CI. other 2 app servers are passing test in "Destination" services and also working when called in "JCo RFC Provider"

Looks it is failing at sap gateway., however, not many users are logged on now.

When pining gateway host, it says alive..

also, SMGW does not show 100 connections.

Thanks,

Hi,

Increase parameter CPIC_MAX_CONV to 500 in your environment variable file.

Also check below links:

Hi,

Please check if ports are open and if you are using the right gateway. Also, check if you are using the right system number.

Thanks,

Rajan
