Real-time data read on Live-Cache

[Former Member]

Currently we have nightly extracts of live cache which is not helping customer to get real-time metrics. Is there a way to read the data directly from live-cache in real-time? I see there are articles on creating virtual provider with BAPI's and other methods.

I just want to get input from forum the best optimal way to access live cache data. I appreciate if you can provide more details on this one.

Thanks

Hello Ravi,

/SAPAPO/OM16 and /sapapo/om19 are provided by SAP to get information about data stored in the LiveCache. If you would like to get your own views, you should write a special report in ABAP using "/SAPAPO/OM"-development class functionality.                        

'/SAPAPO/OM16' and '/sapapo/om19' itself calls a banch of OM- functions to read  data from the LiveCache, e.g.:                                                     

/SAPAPO/OM_RESOURCE_GET_ALL                                                        

/SAPAPO/OM_ORDER_GET_ALL                                                           

/SAPAPO/OM_SETUPMATRIX_GET_DAT                                                     

/SAPAPO/OM_STOCK_GET_BY_UID                                                        

As you know objects stored in the class containers can be accessed and manipulated only via LCA < COM> routines which are  methods of LCAPPS/COM objects. The registration of the LCA routines is done automatically when the liveCache is started by the LC10, check the lcinit.log file.                                 

The shared procedures in the LiveCache are written in C++  and shipped to the customers as binary shared libraries  (LCA/COM-Routines) together with the LiveCache. The original  C++ source code of the libraries is not generally available to the customers.                                                                     

You can get the complete list of the stored procedures  in LC10 or MAXDB studio.

You can read the Config-Files ./sapdb/<LC name>/db/sap/xxx.lst  or check the information in the lcinit.log file.                               

If you need to see the interfaces of the procedures, you may use 'se80' transaction and navigate in the Development class '/SAPAPO/OM'.   

//om Function modules have the documentation available in the latest SCM releases.

I gave you general information on your general question.

Dependent on the data type you are planning to read from the liveCache & SCM version, the solutions might be available by BAPI's or another methods => post more spesific question with your bisness scenario on SCM forum.
