SCM5.0 Live Cache issue

Hello,
I am a newer from SCM5.0. I have 2 questions regarding live cache for SCM5.0.
1) if I want to run SNP or PP/DS, the live cache is necessary. that means, we MUST install live cache for APO planning run.
2) From now on, no 32 bit live cache version for SCM5.0. I can just install 64 bit live cache version for SCM5.0. right?
Could anyone give me some comments on the 2 issue? thanks in advance.
Best Regards,
Karl

Hi Karl,
1. In APO whatever runs you take there should be liveCache. The data will be refreshed from database to livecache and is accessed.
In APO data is stored either order series or time series.
2. Yes you have to install 64 bit.

Kishore Ch

Hello Kishore,
you could check the sizing of the liveCache data.
* Report /SAPAPO/TS_LCM_REORG_SNP has checks of the SNP planning areas for superfluous objects.
* Delete old/temporary APO data.
* /SAPAPO/TS_LCM_REORG report checked TS superfluous objects.
If you didn't create the planning versions, copy of planning versions & data load to liveCache, then create the SAP message to check your system on the question of the dataarea usage.
If you have the long running APO transactions => performance of the SCM system has to be checked.
If you have the bottleneck in liveCache & could not solve the case by yourself => create the SAP message to BC-DB-LVC and get SAP support.

What are the possible live cache issues turn up for demand planning?

HI all,
Can anyone tell me the issues that may arise iin live cache and how to ensure the performance and maintenace of live cache that a planning area is utilizing it.
if the utilization is high how to bring it down!!
Can anyone pls guide me on this!!!
Thanks
Pooja

Hi Pooja,
1) Accumulation of logs created during demand planning jobs will have an impact on performance
and affect livecache and hence to be cleared periodically
2) Livecache consistency check to be performance at planned intervals
which will reduce livecache issues
3) Through om13 transaction, you can analyse the livecache and LCA objects
and act accordingly
4) You can also carry out /SAPAPO/PSTRUCONS - Consistency Check for Planning Object
Structure and /SAPAPO/TSCONS - Consistency Check for Time Series Network related to
demand planning to avoid livecache issues later

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 <b>NOT</b> a physical database, it is a program in C++ that <i>simulates</i> 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

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,

Sure - how did you uninstall the former installation?
rm -f /sapdb/<DBSID> ??
To correctly uninstall a MaxDB/liveCache you'll always have to use the SDBUNINST tool.
Since there seems to be another installation on the same server, it's now a bit complicated to clean up the registration mess... You should open a support message for that. Then we'll see what we can do here.

MAXLOCKS alert generation - SAP Live Cache

Hello Guru's,
We have a requirement for setting alerting for parameter MAXLOCKS on live cache server when it reaches to a threshold value, but we couldn't find any monitoring set in RZ20.
So we have got an idea to use Count(*) on LOCKSTATISTICS and calculate a threshold. But not sure how to do it through Shell Script for MAx DB? Please suggest if any other options as well.
Thanks and Regards,
Sri's

Hello Sri's,
1.
Please review the notes:
65946          Lock escalations
1243937     FAQ: MaxDB SQL locks
As you know, the system table LOCKLISTSTATISTICS displays the statistics of the
lock management since the last database start. This system table is insufficient for the analysis of locking conflicts.
2.
Review the sapact script attach to the SAP Note No. 974758 as HINT to your question on collecting the output
of the statement :
SELECT * FROM SYSDBA.LOCKLISTSTATISTICS     and
SELECT * FROM SYSDBA.LOCKSTATISTICS
Periodically during the job/application run in question.
Also use the DB analyzer to find the bottleneck in liveCache.
3.
Create the SAP message and get SAP support.
It will be helpful to know what is the version of your system, SAP basis SP, the liveCache version and the reason of your project.
Did you get the DB analyzer warnings with lock escalation?
Regards, Natalia Khlopina

How to create a cache for JPA Entities using an EJB

Hello everybody! I have recently got started with JPA 2.0 (I use eclipseLink) and EJB 3.1 and have a problem to figure out how to best implement a cache for my JPA Entities using an EJB.
In the following I try to describe my problem.. I know it is a bit verbose, but hope somebody will help me.. (I highlighted in bold the core of my problem, in case you want to first decide if you can/want help and in the case spend another couple of minutes to understand the domain)
I have the following JPA Entities:
@Entity Genre{
private String name;
@OneToMany(mappedBy = "genre", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<Novel> novels;
@Entity
class Novel{
@ManyToOne(cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Genre genre;
private String titleUnique;
@OneToMany(mappedBy="novel", cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> editions;
@Entity
class NovelEdition{
private String publisherNameUnique;
private String year;
@ManyToOne(optional=false, cascade={CascadeType.PERSIST, CascadeType.MERGE})
private Novel novel;
@ManyToOne(optional=false, cascade={CascadeType.MERGE, CascadeType.PERSIST})
private Catalog appearsInCatalog;
@Entity
class Catalog{
private String name;
@OneToMany(mappedBy = "appearsInCatalog", cascade = {CascadeType.MERGE, CascadeType.PERSIST})
private Collection<NovelEdition> novelsInCatalog;
The idea is to have several Novels, belonging each to a specific Genre, for which can exist more than an edition (different publisher, year, etc). For semplicity a NovelEdition can belong to just one Catalog, being such a Catalog represented by such a text file:
FILE 1:
Catalog: Name Of Catalog 1
"Title of Novel 1", "Genre1 name","Publisher1 Name", 2009
"Title of Novel 2", "Genre1 name","Pulisher2 Name", 2010
FILE 2:
Catalog: Name Of Catalog 2
"Title of Novel 1", "Genre1 name","Publisher2 Name", 2011
"Title of Novel 2", "Genre1 name","Pulisher1 Name", 2011
Each entity has associated a Stateless EJB that acts as a DAO, using a Transaction Scoped EntityManager. For example:
@Stateless
public class NovelDAO extends AbstractDAO<Novel> {
@PersistenceContext(unitName = "XXX")
private EntityManager em;
protected EntityManager getEntityManager() {
return em;
public NovelDAO() {
super(Novel.class);
//NovelDAO Specific methods
I am interested at when the catalog files are parsed and the corresponding entities are built (I usually read a whole batch of Catalogs at a time).
Being the parsing a String-driven procedure, I don't want to repeat actions like novelDAO.getByName("Title of Novel 1") so I would like to use a centralized cache for mappings of type String-Identifier->Entity object.
Currently I use +3 Objects+:
1) The file parser, which does something like:
final CatalogBuilder catalogBuilder = //JNDI Lookup
//for each file:
String catalogName = parseCatalogName(file);
catalogBuilder.setCatalogName(catalogName);
//For each novel edition
String title= parseNovelTitle();
String genre= parseGenre();
catalogBuilder.addNovelEdition(title, genre, publisher, year);
//End foreach
catalogBuilder.build();
2) The CatalogBuilder is a Stateful EJB which uses the Cache and gets re-initialized every time a new Catalog file is parsed and gets "removed" after a catalog is persisted.
@Stateful
public class CatalogBuilder {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private Cache cache;
private Catalog catalog;
@PostConstruct
public void initialize() {
catalog = new Catalog();
catalog.setNovelsInCatalog(new ArrayList<NovelEdition>());
public void addNovelEdition(String title, String genreStr, String publisher, String year){
Genre genre = cache.findGenreCreateIfAbsent(genreStr);//##
Novel novel = cache.findNovelCreateIfAbsent(title, genre);//##
NovelEdition novEd = new NovelEdition();
novEd.setNovel(novel);
//novEd.set publisher year catalog
catalog.getNovelsInCatalog().add();
public void setCatalogName(String name) {
catalog.setName(name);
@Remove
public void build(){
em.merge(catalog);
3) Finally, the problematic bean: Cache. For CatalogBuilder I used an EXTENDED persistence context (which I need as the Parser executes several succesive transactions) together with a Stateful EJB; but in this case I am not really sure what I need. In fact, the cache:
Should stay in memory until the parser is finished with its job, but not longer (should not be a singleton) as the parsing is just a very particular activity which happens rarely.
Should keep all of the entities in context, and should return managed entities form mehtods marked with ##, otherwise the attempt to persist the catalog should fail (duplicated INSERTs)..
Should use the same persistence context as the CatalogBuilder.
What I have now is :
@Stateful
public class Cache {
@PersistenceContext(unitName = "XXX", type = PersistenceContextType.EXTENDED)
private EntityManager em;
@EJB
private sessionbean.GenreDAO genreDAO;
//DAOs for other cached entities
Map<String, Genre> genreName2Object=new TreeMap<String, Genre>();
@PostConstruct
public void initialize(){
for (Genre g: genreDAO.findAll()) {
genreName2Object.put(g.getName(), em.merge(g));
public Genre findGenreCreateIfAbsent(String genreName){
if (genreName2Object.containsKey(genreName){
return genreName2Object.get(genreName);
Genre g = new Genre();
g.setName();
g.setNovels(new ArrayList<Novel>());
genreDAO.persist(t);
genreName2Object.put(t.getIdentifier(), em.merge(t));
return t;
But honestly I couldn't find a solution which satisfies these 3 points at the same time. For example, using another stateful bean with an extended persistence context (PC) would work for the 1st parsed file, but I have no idea what should happen from the 2nd file on.. Indeed, for the 1st file the PC will be created and propagated from CatalogBuilder to Cache, which will then use the same PC. But after build() returns, the PC of CatalogBuilder should (I guess) be removed and re-created during the succesive parsing, although the PC of Cache should stay "alive": shouldn't in this case an exception being thrown? Another problem is what to do when the Cache bean is passivated. Currently I get the exception:
"passivateEJB(), Exception caught ->
java.io.IOException: java.io.IOException
at com.sun.ejb.base.io.IOUtils.serializeObject(IOUtils.java:101)
at com.sun.ejb.containers.util.cache.LruSessionCache.saveStateToStore(LruSessionCache.java:501)"
Hence, I have no Idea how to implement my cache.. Can you please tell me how would you solve the problem?
Many thanks!
Bye

Hi Chris,
thanks for your reply!
I've tried to add the following into persistence.xml (although I've read that eclipseLink uses L2 cache by default..):
<shared-cache-mode>ALL</shared-cache-mode>
Then I replaced the Cache bean with a stateless bean which has methods like
Genre findGenreCreateIfAbsent(String genreName){
Genre genre = genreDAO.findByName(genreName);
if (genre!=null){
return genre;
genre = //Build new genre object
genreDAO.persist(genre);
return genre;
As far as I undestood, the shared cache should automatically store the genre and avoid querying the DB multiple times for the same genre, but unfortunately this is not the case: if I use a FINE logging level, I see really a lot of SELECT queries, which I didn't see with my "home made" Cache...
I am really confused.. :(
Thanks again for helping + bye

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
