Live cache DBM access

Hi Experts
If I stop Livecache in LC10, only SQL access is coming down but DBM access is not totally. Though I can see the message "Live cache is successfully stopped".
How to bring down the DBM access along with SQL access for LC 7.9
I would appreciate your help and guidance
Thanks in advance

Hi Experts,
Need your quick support.. Please
If we stop livecache in LC10, should both the SQL and DB access show as " No" (or) only SQL access stopped and DBM access still showing as "Yes" is fine?
for me only SQL access shows No and DBM access "Yes" even after successfully the livecache in LC10.
Note : In Maxdb studio the database showing as stopped but at the OS level few servers are running after x_server stop as well.
I would appreciate your support.
Thanks in advance

Live Cache DBM error

Hi,
Our Live cache log backup runs to tape, sometimes this may fail and our log area starts increasing, when we try to take a log backup uisng DBMGUI or DBMCLI we get below error.
ERR
-24988,ERR_SQL: SQL error
-104,DBM command impossible at this time
Can you please help how to resolve this ?, since it is something critical for us during our business close end,
Thanks,
Chetan

> Our Live cache log backup runs to tape, sometimes this may fail and our log area starts increasing, when we try to take a log backup uisng DBMGUI or DBMCLI we get below error.
Hmm... that is usually not the way it should work - I assume you're employing a third party backup tool here?
If not, than you definitively shouldn't create the log backup directly to tape.
Instead you should use the AUTOLOG backup to the filesystem and afterwards archive the backups to the tape.
> ERR
> -24988,ERR_SQL: SQL error
> -104,DBM command impossible at this time
Well, it means what it says: for some reason (e.g. there is already a backup running) you cannot start the backup right now.
For more detailed answers we need to see the log files of the database.
> Can you please help how to resolve this ?, since it is something critical for us during our business close end,
Hmm... what has your liveCache to do with your business (month?) end closing??
Anyhow, if something is important1, critical2 or urgent3 then the forum might not be the place to go.
In such cases always open a support message - there you've got guaranteed response times.

please don't blame me for adding the numbers to the three bad words above - this was the only way to get around the awkward content filtering of this forum

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.
Since then, we get following error in LC10.

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

Live Cache Monitoring. DBM_CONNECT DBM Error

Hi Gurus,
I have Installed TM7.0 system which is on NW7.0 with EHP1 on windows server2003 and Oracle DB. i have also installed SCM optimizer.
after i installed Live Cache, in transaction LC10 i have maintained the data in integration tab. When i click the 'liveCache : monitoring' tab i get the following error.
Name and Server     : TM7 - CTSGVCSAPBL07
DBMRFC Function     : DBM_CONNECT
Error               : DBM Error
Return Code         :         -2

This implies that the connectivity to the MaxDB database is giving authoization error.
The user with which i have logged in(SAP logon) has the following roles -
SAP_LCA_ALL
SAP_BC_LVC_SUPERUSER
Thanks in advance
Sriram

Hi,
please take a look at SAP note 990602, specifically point 11; use transaction DB59 to check the connection to your liveCache instance.
From the error message you receive, it seems likely that the integration data (user/password combination) for your liveCache instance is incorrect.

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...

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'.

Why we need live cache along with RDB in APO

Hello Expert,
I recently entered to APO module so want to know about live cache and why we really need comparing to RDB and what RDB cannot do that live cache can do?

SRS,
Functionalities are pretty much the same. LiveCache is a relational Database, built on MaxDB.
Advantage of LC is that most of the data is stored in memory rather than on disk storage. Data access and retrieval is substantially faster from memory than from disk storage.
Best Regards,

Data movement from R/3 DB to APO DB and to Live cache

Dear APO Experts,
I have few questions on live cache and how it works, I understand that Live cache is memory resident database. below are my questions.
1) What sought of data move from R/3 DB to APO DB and then to Live cache DB
2) When data moves from APO DB to Live cache, till how much duration that data stays in live cache
3) And how does data gets pulled in to live cache from APO DB
4) Why do we require live cache logs while data never gets commited to hard disk
5) Do we ever add a datafile to Live cache DB
any info that you provide on this will be really helpfull to me
Thanks,
Chetan

Hello Chetan,
As you know, itu2019s MAXDB/liveCache forum.
What is the version of your system?
The is documentation available at:
 SAP liveCache technology
< Please review document u201CWhat is SAP liveCache technology?u201D >
Sap documents at service.sap.com/scm -> Technology:
u201CliveCache overviewu201D and u201CIntegration overviewu201D
For SAP liveCache documentation also see the SAP note 767598.
Go to SAP link Best Practices for Solution Management: mySAP SCM at SAP liveCache technology ...
And Review the document u201CManage APO Core Interface in SAP APO (3.x) / mySAP SCM (4.x/ 5.0)u201D
1. As you saw in the reference documents the data transferred from the connected R/3 system to APO.
And the transactional data could be uploaded to the liveCache, if you downloaded them
to the APO database cluster tables first. This procedure steps are running during the
system upgrade < for example, from SCM 5.0 to SCM 7.0 ) u2013 report /SAPAPO/OM_LC_UPGRADE_70 steps. Or you want to migrate the
liveCache to another operating system or convert your system to Unicode,
and therefore you want to back up the liveCache data first so that you
can reload it into the liveCache afterwards - SAP Note No. 632357.
2. Could you collaborate more on this sentence. Could you give examples?
3. u201CAnd how does data gets pulled in to live cache from APO DBu201D
 The data are not pulled from the APO DB to liveCache.
 When you changed the APO data on the system the LCA procedures have been called from ABAP. The objects stored in the class containers in liveCache can be accessed and manipulated only via LCA routines. The registration of the LCA routines is done automatically when the liveCache is started by the LC10. The LCA procedures in the LiveCache are written in C++
and shipped to the customers as binary LCA libraries(LCA build) together with the LiveCache.
< See more details in SAP Note No. 824489 or 1278897 as of SCM 7.0 >
4. See the SAP notes:
 869267 FAQ: SAP MaxDB LOG area
 1377148 FAQ: SAP MaxDB backup/recovery
5. You could run the quicksizer & estimate how much data you are planning to have in liveCache.
 Also the amount of data could be increased by the creation of the new data in APO by users
 Or another reason u2026
 In general you will add the datavolume to solve or prevent the DB_FULL issue,
 See u201C17. What do I do if the data area is full? u201C in SAP note 846890.
Thank you and best regards, Natalia Khlopina

Error saving transport requisition to live cache

Hi Gurus,
while location heuristic running getting in bottom line message like error saving transport requisition to live cache.kindly suggest me soon.
regards,
babu

Dear Rajendra,
The error message seems to occur during the deletion of the purchase
requisitions when running the heuristics. The error /SAPAPO/SNP028
occurs when SNP tries to access the order data whose master data has
been changed. So, when the order's master data has changed and no
longer represent the existing one, you get this error message.
Please run the report
/SAPAPO/RLCDELETE before running the heuristics job manually to delete the inconsistent data.
So here the product 20508050 @ Mc5000-ZA59 the existing purchase
requisitions might not have anymaster data like Means of transport or PDS. Can you please delete
these inconsistent orders and run the heuristics again to check if
the orders are still created with inconsistent means of transport.
Also run consistenct reports /SAPAPO/TS_LCM_CONS_CHECK and OM17 and correct if any inconsistency is present.
BR,
Thushitha V.

Live Cache config prob!!!!!!

Dear All,
I have just installed IDES of SCM 5.0 and scheduled and released the default jobs from sm36. But from sm37 I can see that the jobs are getting cancelled .
1)" Connection to LiveCache Failed " .
2)" LiveCache Lock Server not Accessible " .
I have installed ABAP + JAVA and logged in client 001.
Please advice ........
Regards,
Souren

Hi Natalia,
Thanks for the reply.
Ours is win2k3 32 bit system where we have installed :
(1) Oracle 10.2 &
(2) SCM 5.0 server (Central System Installation).
During Installation, SAPinst asked for Live cache related details (eg, Live Cache ID - we have given LC1, Control user's Pwd etc) along with the installation DVD for the same - where we have given the DVD 51032259_11 (NW 2004s SR2 liveCache 7.6.0 Windows Server on IA32 32bit).
The installation completed successfully. Our SCM system id is SR3.
**Does this mean that Live Cache Server got installed ??
After the above installation, we have referred the "Installation - SAP liveCache Technology on Win - NW 7.0 SR2" and tried to do the post installation steps (Assuming that Live cache got installed )
We created the RFC user with all the authorizations as described in the SAP note for the same.
During the post installation step :
dbmcli d <SID> -u <controluser>,<password> db_offline,
we got the following error:
ERROR! Connection failed to node <LOCAL> for database <SID>:
Database instance not found.
We tried with both SR3 & LC1 as SID but the result is same.
Further, we tried the next post installation step using LC10.
After Integrating LCA,LDA & LEA, when we tried to "monitor" the Live Cache (by clicking the Live Cache: Monitoring button), we got the following error:
DBMRFC Function : DBM_CONNECT
Error :DBM Error
Return Code : -4
Error Message database instance not found
How should we proceed now??
Thanks & Regards,

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.
Sume

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!
Regards,
Roland

Live cache COM routine ended with own error code 38

Hi Experts,
the process chain got failed and it is showing the error as error 38.when we are doing the analysis the error itself coming in the extractin level and it is showing as errors in the source system and not more than that. Please gimme some solution how to solve it.

Hello,
This is the object not found error for /SAPAPO/OM_PEGAREA
These error codes are generated if you try to access or manipulate an
object that cannot be found in the live cache (any more).
Normally this means that there is no object with the key (GUID) provided
by the ABAP.
Please execute the transaction /SAPAPO/OM17 inorder to resolve the
inconsistencies regarding missing pegkeys.

Live Cache x_server throwing error when starting

ok, fixed it.
Putting the dtd on a machine that it can see solved it... would be nice if the doc mentioned that your test machine (the one that it warns is insecure as everything is installed as root etc etc) needs to have outgoing internet access...
Ho hum.
Oddly, requesting that dtd from sun gives a 500 - using:

Installing Live Cache Server on SCM 4.1 system

Hi All,
I have installed an SCM 4.1 Abap + Java System and Live cache client was installed during SCM 4.1 installation.
I would like to install Live cache server and i have problems with it.
I have downloaded the following installation guide
SAP liveCache 7.5.0 For SAP SCM Server 4.1
Document Version 1.02 u2013 April 8th, 2005
Guide tells us to use installation master CD for installating Live cache Server but note 708118 tells us to use the CD 51031447
04 Nov 05 Windows AMD64: Start Installation from liveCache CD
Start the installation of the liveCache server or client from the liveCache
CD (number 51031447) and not from the installation master CD (number
51031443)
Upon checking the cd 51031447 i see SDBINST.exe and upon clicking it i get the following screen
