Transport Changes not reflected in server

[#1]

Dear Experts,

Sometimes, It happens after transporting request with RC0, we are not able to see changes in system

we have to log out from the system, then after log in we are able to see changes.

Could anyone tell why it's happening

Hello,

As per your description of the incidence, it sems that there is a synchronization problem.

As mentioned in [SAP Note 36283|http://service.sap.com/sap/support/notes/36283|Link to SAP Note 36283]:

Buffer synchronization makes sure that application servers are informed

about changes to buffered tables or other buffered objects that were

made on other application servers or using transport tools.

Therefore buffer synchronization is carried out at a delay. The period is controlled

using profile parameter rdisp/bufreftime. For performance reasons, the value

should never be set to less than 60 seconds.

Please check the value of parameter rdisp/bufreftime in your system. Its default value is 120, and it should not be set to a value lower than 60. So if you have a rdisp/bufreftime parameter with a value between 60 and 120 we can consider that it is okay.

In addition, and as mentioned in [SAP Note 106764|http://service.sap.com/sap/support/notes/106764|Link to SAP Note 106764]:

the synchronization is controlled by three software parts: tp, R3trans and SAP system

Therefore, updating the TP and R3trans might help (if any bug related to synchronization has been detected in an old version of TP or R3trans, a fix has been delivered in newer version). You will find the latest version of TP and R3trans programs in the [SAP Service Marketplace|http://service.sap.com/patches].

Regarding the SAP System, there is a parameter that must be set correctly to avoid synchronization problems. The parameter is called rdisp/bufrefmode and its value depends on whether you have a central system (only one instance) or a system with several application servers:

- Central system (only one application server):

rdisp/bufrefmode = sendoff,exeauto

- A system with several application servers:

rdisp/bufrefmode = sendon,exeauto

In [SAP Note 14754|http://service.sap.com/sap/support/notes/14754|Link to SAP Note 14754] you will find further information about rdisp/bufrefmode and rdisp/bufreftime parameters.

If the value of those parameters are correct and the incidence persists, you can use program RSDBBUFF mentioned in [SAP Note 36283|http://service.sap.com/sap/support/notes/36283|Link to SAP Note 36283], it will help you to analyse buffer shyncronization problems.

Hi Manuel,

How can i check version & updating details of Tp and R3 trans...... I mean to say what commands or T-codes should be execute for checking version

[manuel_suarez]

Hello,

To find out your current version of TP and R3trans you can execute the following command at operating system level:

TP -v

R3trans -v

In the output of the command you will find the version and patch number.

In the SAP Service Marketplace you will find the latest version of TP and R3trans here:

http://service.sap.com/patches --> Browse our Download Catalog --> Additional Components --> SAP Kernel --> <choose your version: 32 or 64 bit and Unicode or non-Unicode> --> <choose your kernel release> --> <choose your operating system> --> #Database independent

here you will find the latest TP and R3trans. If you click in the Info link you will find the version and patch number.

Best regards,

Manuel.
