Hi Ashebook,

all the liveCache errors are logged in the file knldiag.err. You should check this file regularly for errors.

Thanks,

Hello Ashebook,

with transaction LC10 you can administrate your liveCache. Here you have the possibility to get irectly into transaction RZ20 where you can check the liveCache Alerts.

You will find detailed information about CCMS for MaxDb and liveCache in FAQ Note <a href="http://<https://websmp104.sap-ag.de/~form/handler?_APP=01100107900000000342&_EVENT=DISPL_TXT&_NNUM=990602&_NLANG=EN>">990602</a>

Hello Raja,

For SAP liveCache documentation in English:

http://help.sap.com/saphelp_nw04/helpdata/en/f2/0271f49770f0498d32844fc0283645/frameset.htm

( please see the liveCache terms 'Data Cache' & 'OMS Data' )

As you know objects in liveCache stored in the class containers can be

accessed and manipulated only via LCA ( liveCache Applications ) routines

( Database Procedures ) which are methods of LCA ( 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 ( dynamic linked )procedures in the LiveCache are written in C++

and shipped to the customers as binary shared libraries ( dynamic linked )

(COM-Routines or LCA-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 using SQL Studio

(shipped with the LiveCache):

just connect to the LiveCache as Standard livecache user ( SAPR3 or SAP<LC-SID>

By default ) with the password 'SAP'( default ).

You can read the Config-Files ./sapdb/<LC name>/db/sap/xxx.lst

or check the information in the lcinit.log file.

Names of all registered procedures, which have been called from ABAP, you can find

executing 'lc10' transaction on your SAPAPO system:

LiveCache Monitoring ->Problem Analysis -> Database Procedures .

If you need to see the interfaces of the procedures, you may use 'se80'

transaction and navigate in the Development class '/SAPAPO/OM'.

The transaction /n/SAPAPO/OM16 is 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' itself calls a bunch 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

You can get more information about liveCache and LCA object at the following links:

Thank you and best regards, Natalia Khlopina

Hi Raja,

SAP liveCache technology is an object-based enhancement of the MaxDB database system and was developed to manage complex objects (e.g. in logistical solutions such as SAP SCM/APO)

In solutions of this type, large volumes of data must be permanently available and modifiable. You can use SAP liveCache technology to represent data structures and data flows (such as networks and relationships) more easily and effectively.

In contrast to MaxDB, with an optimally configured SAP liveCache database instance, all data which must be accessible to the database system is located in the main memory.

There are standard function module available to extract data from live cache. For example, function module /SAPAPO/TS_DM_EXTRACT_DATA is used to extract SNP safety stock forecast from live cache.

Hope this will help.
