Live Cache Crashed

Hello Guru's,
My Production system Live cache has been crashed. I am trying to restore the last backup which was taken yesterday night 8:00pm. I am able to restore the Live Cache however unable to restore the logs to recover PIT, as it is complaining about log sequence. I am not sure about finding the sequence number it is asking for.
Crash happened today morning 7:00am. Backup restored last night 8pm and trying to do point in time recovery. Backup has been restored and trying to apply logs.
Note;- log backup is for every 2 hours, so after the complete backup last night, we have log backup's for every 2 hours and trying to apply the same.
Kindly suggest what can be done..
Thanks,
Sravanthi.

Hello,
1.
You have questions how to solve the liveCache issues on the PROD system
=>
As already recommended Lars, please open the SAP message to the component BC-DB-LVC to get SAP support.
It will be helpful to know the SCM/APO version, liveCache version and more details about the liveCache crash.
2.
In case you had the liveCache crash due the hardware problems, and the data or log volumes or liveCache configuration files are corrupted
=>
solve the hardware issues first or use another server
Follow the SAP note to create the liveCache instance:
    457425     Homogenous liveCache copy using backup/restore
   You need to create/initialize the liveCache instance for restore or run the Restore with initialization, restore the successful databackup, then leave the liveCache in admin status and continue the restore of the incremental databackup/logbackups in sequence if needed.

Live cache Recovery.....

Hello all,
This is related to SAP DB version 7.4.3.32 and it is running on Windows. My DBM GUI version is 7.6.00.12. On the recovery tab of the DBM GUI there is a option called "Recovery with Initialization". I have used this option to recover my SAP DB database and it was always successful. I used this option to intialize the existing database with a good full backup. This is a new option in 7.6.00.12 DBM GUI. It was not there in 7.4.3.30 DBM GUI. Though it is not a good option all the time but it is very good if your database is crashed and if you have latest good full backup then you can use this option for recovery.
My question is that I have never tried this option (Recovery with Initialization) on our Live Cache database (SAP DB instance installed as Live Cache on Solaris). I do see this new option in DBM GUI in 7.6.00.12 DBM GUI as DBM GUI is same for both type of database.
Is it possible to use this option for our SCM 4.0 Live Cache in same way I have used it for SAP DB database. It will be a very good option for Live Cache if we have one good backup and Live Cache is crached then we can use the latest full backup to restore the Live cache.
Please let me knwo if anybody knwos about it or have tried it.
I will really appreciate your help.
Thank you.

Hi,
with liveCache it's a little bit different as opposed to an OLTP instance. The most imporant difference being that when you're using liveCache, there's always another DB instance aswell, the SCM/APO instance. The consistency between these two instances is of the utmost importance. Therefor, after every recovery of liveCache, you should run certain consistency reports to make sure the data in liveCache and SCM DB are consistent.
A normal liveCache recovery would look like this:
- you've got a (successfully saved) full data backup
- you've got several log backups
Using the above backups, you can minimize the loss of important data when experiencing crashes.
In your first case, you would recover using the last full data backup and could then continue to recover all available logbackups (either manually or automatically created).
> You could do a recovery without initialization here aswell, because all changes should still be on the logvolumes.
In the second case, you would just recover + init the data backup from Jan 1st.
In BOTH cases, you should run the consistency reports afterwards!

Roland

Live cache backup

Hi Experts,
I am beginner to SCM and Live cache technology.
I have sucessfully installed SCM 5.0 and Live cache 7.6.29 on two different HP-Ux 11.23 servers.
My first requirent is to take live cache backup. But there is no tape drive connect to any of the server,
local file system assigned as backup space, accordingly I have successfully taken online backup of SCM database by modifying entries like backup_dev_type to tape in init<SID>.sap.
Know I am facing a challenge to take live cache backup on local file system , infact dont know how to take online live cache backup.
Another question is database manager gui is needed in unix environment, if yes please let me know the procedure how to configure this as In transaction lc10 upon double clicking database manager gui system generating error.
Please help to solve the above two problems.
Thanks & Regards,
Maqsood Ahmed

Hi Ahmed (no own SDN account? ).
I'd like to make a few remarks on this:
1. Backup to local filesystem w/o moving it to another location afterwards is next to useless. What happens when (when not if!), the local disk crashes? What backup can you use then?
2. You can perform liveCache Backups from DB13C/DBACockpit after you've integrated the liveCache instance (DB59).
3. If you like to administer the liveCache via DBMGUI - just install DBMGUI on your Windows Workstation and connect remotely to the liveCache. Actually this is the way how it was thought up.
For detailed information how to work with liveCache I propose you check:
The documentation [Backup/Recovery SAP Library - Database Administration in CCMS: SAP liveCache Technology|http://help.sap.com/saphelp_nw70/helpdata/EN/e9/dc1c3e46903b2ee10000000a114084/content.htm]
The SDN Content on liveCache [https://www.sdn.sap.com/irj/sdn/livecache]
The SCM Technology pages in the SAP Service Marketplace [https://service.sap.com/scm] -> SAP SCM Technology
Good luck,

Live cache was down

Hi All,
The live cache instance on my SCM was down yesterday.
However it was got up again thro' LC10.I'm trying to find the reason for it being down.
Can someone please suggest how can I get this information.
I can see the following in knldig around the sametime.Is it becuase of the autolog option.

Hi,
it seems quite strange that you do not see any errors within knldiag.err that might explain why your liveCache instance was down at the time and a restart was needed. If there was no crash or anything remotely similar, somebody triggered liveCache to go down manually? You might want to check dbm.prt, dbm.utl and lcinit.log / lcinit.his to see whether this was the case.
Regarding the XServer, you should have a XServer protocol file with the /sapdb/data/wrk directory.
Regards,
Roland
P.S.: which exact liveCache version (incl. Buildnr.) and OS are you using?

Unable to delete Order does not exist in live cache but in table POSMAPN

Hi Experts,
We are facing an issue where purchase order is not available in live cache (which means no GUID) but exists in database table POSMAPN. We have tried to delete it using standard SAP inconsistent order deletion program and also using BAPI BAPI_POSRVAPS_DELMULTI but not able to delete it.
Can anybody suggest a method by which we can get rid of this order from the system.
Thanks a lot.
Best Regards,
Chandan

Hi Chandan,
Apologize me for taking your question in a wrong perspective. If you want to delete the same then you need to Re-CIF the order from ECC so that it would come and sit in Live Cache. Once done, try using the BAPI.
If you are not successful with the above approach try running the consistency report /SAPAPO/SDRQCR21 in APO system
so that it first corrects the inconsistency between ECC and APO (Live Cache + DB tables) and then use the BAPI to delete the PO.
Not sure if you have tried this way. If this does not solve your purpose you need to check SAP Notes.
Thanks,
Babu Kilari

What is the significance of Live Cache in demand planning ?

Hi all,
Can anyone explain me significance of live cache in the demand planning. What are the issues will turn up for live cache if it is not properly maintained?
Thanks
Pooja

Hi Pooja,
SAP has come up with Live cache concept for storage and most important, quick and efficient processing of transactional data. Its a layer between data base and GUI and even the search methods and storage space has been optimized due to its structure. In DP it is used for storage of time series data whereas in SNP it can store both time series and order series data.
Regarding your second query, it is recommended to have Live cache consistency on a periodic basis for synchrinising data between LC and database tables. You can face many issues due to LC inconsistency as incorrect time series generation, Transactional data discrepancy, COM routine errors during background processing etc.
Let me know if it helps

Gaurav

BAPI to get the Quantity from orders in live cache.

Hi Folks,
Can any body provide me the BAPI to get the quantity value for the orders saved in the Live Cache. I tried using the BAPI
BAPI_SLSRVAPS_GETLIST2 ... but its not fetching any records for me. what else i need to provide it as input.
Thanks in advance.
Thanks & Regards,
Ramana

Check this thread.
Delete In-Transits.
In-Transit is not a particular order. Any Goods Movement from one location to another location will be considered as In-Transit.
Let's say Plant A is sending Product P1 to DC B against a Purchase Order.
In that case in plant A the stock will be reduced by the quauntity of goods being shipped.
At DC B, the Purchase Order will become In-Transit Stock.
Thanks,
Somnath

DBM Error return code -11 in LC10 Administration in SCM System Live Cache

Hello,
We have installed SCM 4.1 on Solaris on one box and LC 7.5 on another solaris box.
For kernel upgrade, we shut down Live Cache using LC10>administration on SCM server. After kernel patch, other patches for ABAP stack, we upgraded LC to SP11 build 35.

Thanks and regards,
Vaibhav

Hello Vaibhav,
while using transaction LC10, the error 11 "tp error: Terminating. [nlsui0.c ...]" occurs. The user authorization with tp fails and the application server cannot connect to the liveCache.
I assumed, that it's due to a library version mismatch, tp cannot use the liveCahe UNICODE libraries.
Please check, that the tp call at the command line works properly. And a dbmcli call in the transaction SM49 with the tp options
(dbmcli ::
-d <LC-SID> -n <LC-servername> -tpp <profile> -tpi <system-SID>
-tpc <connection - LCA/LDA> dbm_version)
works also properly.
I recommend you to update the liveCache client software on the Application server.
If you've got access to OSS/Service Market Place, then please take a look at note
649814 how to update the liveCache client software on the application server.
< Please also review the SAP notes 847736 & 831108 >
Before the liveCache client version will be upgraded on the application
server you can use the workaround by switching off the central authorization for the liveCache LCA/LDA connections:
In transaction LC10, choose Integration and deactivate the option Central authorization, then save.
If you are the official SAP customer, I recommend you to create the ticket to SAP on 'BC-DB-LVC' queue.
Thank you and best regards, Natalia Khlopina

Data fetch from live cache

How can I retrieve data from live cache?This is in Demand Planning : SCM APO.
Please suggest ways.
Thanks & Regards,
Savitha

Hi,
some time ago I worked on SAP APO.
To read live cache, you first have to open a SIM session.
You can do this as shown in this function module:
FUNCTION ZS_SIMSESSION_GET.
*"*"Local Interface:
*" IMPORTING
*"     REFERENCE(IV_SIMID) TYPE /SAPAPO/VRSIOID
*" EXPORTING
*"     REFERENCE(EV_SIMSESSION) TYPE /SAPAPO/OM_SIMSESSION
CONSTANTS:
lc_simsession_new       TYPE c LENGTH 1 VALUE 'N'.
DATA:
lt_rc                   TYPE /sapapo/om_lc_rc_tab,
lv_simsession           LIKE ev_simsession.
IF NOT ev_simsession IS INITIAL.
    EXIT.
ENDIF.
*--> create Simsession
CALL FUNCTION 'GUID_CREATE'
    IMPORTING
      ev_guid_22 = lv_simsession.
*--> create transactional simulation
CALL FUNCTION '/SAPAPO/TSIM_SIMULATION_CONTRL'
    EXPORTING
      iv_simversion            = iv_simid
      iv_simsession            = lv_simsession
      iv_simsession_method     = lc_simsession_new
      iv_perform_commit        = space
    IMPORTING
      et_rc                    = lt_rc
    EXCEPTIONS
      lc_connect_failed        = 1
      lc_com_error             = 2
      lc_appl_error            = 3
      multi_tasim_registration = 4.
IF sy-subrc > 0.
    CLEAR ev_simsession.
*   error can be found in lt_rc
ENDIF.
* return simsession
ev_simsession = lv_simsession.
ENDFUNCTION.
Then you can access the live cache.
In this case we read an order (if I rememver correctly, it's a plan order):
DATA:
lv_vrsioid                  TYPE /sapapo/vrsioid,
lv_simsession           TYPE /sapapo/om_simsession.
* Get vrsioid
CALL FUNCTION '/SAPAPO/DM_VRSIOEX_GET_VRSIOID'
    EXPORTING
      i_vrsioex_fld = '000' "By default
    IMPORTING
      e_vrsioid_fld = lv_vrsioid
    EXCEPTIONS
      not_found     = 1
      OTHERS        = 2.
CALL FUNCTION 'ZS_SIMSESSION_GET'
      EXPORTING
        iv_simid      = iv_vrsioid
      IMPORTING
        ev_simsession = lv_simsession.
CALL FUNCTION '/SAPAPO/RRP_LC_ORDER_GET_DATA'
    EXPORTING
      iv_order      = iv_orderid
      iv_simversion = iv_vrsioid
    IMPORTING
      et_outputs    = lt_outputs
      et_inputs     = lt_inputs.
If you change something in your simsession, you have to merge it back afterwards, so that your changes become effective.
You can do this like that:
* Merge simulation version (to commit order changes)
CALL FUNCTION '/SAPAPO/TSIM_SIMULATION_CONTRL'
    EXPORTING
      iv_simversion                = lv_vrsioid
      iv_simsession                = lv_simsession
      iv_simsession_method         = 'M'
    EXCEPTIONS
      lc_connect_failed            = 1
      lc_com_error                 = 2
      lc_appl_error                = 3
      multi_tasim_registration     = 4
      target_deleted_saveas_failed = 5
      OTHERS                       = 6.
I hope this helps...

Data storage in Live Cache

Hi,
Can some1 explain me how the SNP data is stored in the live cache.
I know it's by series of order. But tell me is there any mapping involved in it?
Thanks,
Siva.

Order series data is used by both SNP and PPDS.
While I do not know the exact way data is stored in liveCache the following helps me to explain and understand.
Each record in liveCache for Order Series data is stored as
Location Product combination-ATP Category-Quantity-Time Stamp.
Unlike Timeseries data CVC is replaced by a location product combination only, keyfigure is replaced by ATP Category (each kind of Order elements has its own ATP Category) and Time Bucket is replaced by actual Time Stamp (in UTC ddmmyyyyhhmmss format).
The mapping is essentially with ATP Category which maps to corresponding MRP elements in ECC or R/3.
In the SNP Planning Area for each keyfigure the Category Group defines the grouping of ATP Categories for which orderseries data will be displayed in that particular keyfigure.
Hope this helps.
Thanks,
Somnath

How to see Live cache order number in planning book of APO ?

I am trying to see the Live cache order number in Planning book by entering getio as T-code while in planning book.
By this I am not able to see the LC details. Can anyone help me out on the same?

Unable to login to Live Cache

Hi,
I've just completed an SCM 2007 Installation alongwith the live cache.
However, when I try to login to the LC using the dbmcli command (user control/superdba & the pwds. set during installation), it gives the foll. error:
-24950,ERR_USRFAIL: User Authorization failed.
Also, I'm not able to use LC10-->Live Cache Monitoring
Pls help, since it's extremely urgent.
Thanks a lot,
Saba.

Hello Saba,
-> For SAP liveCache documentation in English see the SAP note 767598.
-> In general, the error could be due the wrong password of the dbm user.
 For example, I created the database instance NLK with the control user and
 control password. If I will try to connect to the database with wrong password
 I will get this error ::
 dbmcli -d NLK -u control,test
 Error! Connection failed to node (local) for database NLK:
 -24950,ERR_USRFAIL: User authorization failed
-> You are running SCM 2007 < SCM 5.1 > system, therefore you are SAP customer.
 Please create the SAP ticket concerning this issue => we could logon via OSS and check the status of your system.
 Please set 'high' priority of the ticket, if it's extremely urgent.
 If it's the DEMO or PROD system you could escalate the message to 'VH'.
Thank you and best regards, Natalia Khlopina

In which table is the Live cache data stored?

Hi experts,
I am new APO .Can anyone let me know in which database table will the Live cache data be stored?
Thanks in advance
regards
Ashwin.

Hello Ashwin,
the idea of the liveCache is to haev data permanently and quickly available without having to read/write from/to database. Therefore, the liveCache is NOT a physical database, it is a program in C++ that simulates a database and holds the data in the memory.
However, it does need so called liveCache-anchors which are saved on the database, and which are similar to pointers.
However, you can extract data from liveCache using BADIs or by creating a datasource on a planning area (for DP and SNP), manipulation can also be done only by BADIs or sophisticated programming (which basically uses RFCs).
I hope this answers your question.
Regards,
Klaus
