There are two types of background work process. They are A type and B type. A type background work process are used for mission critical jobs. Background jobs of priority a have high priority than B type back ground jobs. Update Work Process. Update work processes execute update requests. You need at least one update work process per SAP system and you can have more than one per dispatcher. SAP ABAP Application Component BC-CCM-BTC (Background Processing).

Go to transaction code RZ03 to change to the new configured operation mode. A restart of SAP system is needed to apply the changes. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Symptom You want to increase the work process for background by decreasing the dialog work process. Temporary Increase Create a temporary operation mode in transaction code RZ04 as per desired value.
Note You can also doing the same steps for decreasing the background work process. Share on Twitter Share on Facebook. In contrast to dialog processing, batch processing can highly benefit from parallelism on the application server.
Historically, the default number of work processes used in a DTP is 3. In the meanwhile, customers have application servers with much more CPU threads than years ago. This is called intra-query parallelism. Creating the sub-tasks of such a query is done automatically by SQL Server. You do not have to define a package size, but you can control the maximum number of CPUs, which are used by an operator.
This plan can be either a serial or a parallel plan. An execution plan consists of several operators iterators. Each of them can be either serial or parallel. An execution plan with at least one parallel operator is called a parallel execution plan.
SQL Server will not create a parallel plan in the following cases:. A parallel execution plan does not contain the number of logical CPUs used. The actual degree of parallelism DOP is decided at runtime of the query. SQL Server intra-query parallelism typically decreases the runtime of a query, but it can result in varying execution times of the same query: You can configure MAXDOP, but the actual DOP may be different when running the same query again!
Therefore, the actual runtime of a query is not predictable any more. Batch-mode operators are much faster than row-mode operators. Hence, we want to make sure, that there are always sufficient resources for running the query in parallel DOP 2 or higher. Therefore, no parallelism is used for running a single database query As a matter of course, you can still run many database queries in parallel.
We wanted to avoid the overhead of intra-query parallelism and keep a predictable query runtime. However, in the meanwhile, customers often have more logical CPUs available on the database server than concurrently running SQL queries. Not using intra-query parallelism would simply be a waste of CPU resources. Therefore, we would always benefit from intra-query parallelism. The latest version of SQL Server provides an optimizer hint, which enforces the creation of parallel plans.
Therefore, all operators in an execution plan for SAP BW queries are parallel, if possible be aware, that execution plans with a spool table never contain any parallel operator : To benefit from these forced parallel execution plans, you have to apply the newest SP und CU of SQL Server and the correction instructions of.
The created execution plans are slightly different from normal parallel execution plans, because all operators are parallel see NonClustered Index Seek in the picture above. SAP NetWeaver uses a single-threaded, multi-process application server.
Parallelism on the application server has to be explicitly coded. Furthermore, it is often not easy or even impossible to divide a task on the application server in sub-tasks of similar size.
Using intra-query parallelism on the database server is much easier. More and more functionality in SAP is being pushed down from the application server to the database server. The main idea behind this is to reduce the network load between application server and DB server. However, such a DB pushdown has further advantages. You can now benefit from intra-query parallelism without manually generating sub-tasks.
A new algorithm improves performance beyond the usage of additional CPUs. Parallelism is the key for reducing response time. However, it could result in a reduced throughput, particularly in high-loaded ERP systems.
Parallelism on the SAP application server has to be manually adjusted, dependent on the available CPU resources and the size of processed data. You must be a registered user to add a comment.
