To optimize Unwired Server
performance, configure the thread stack size, maximum and minimum heap sizes, and user options
such as enabling trace upload to SAP® Solution Manager.
- Open Sybase Control Center.
- In the left navigation pane, expand the Servers folder and select a server.
- Select Server Configuration.
- In the right administration pane, select the General tab.
- Configure these replication payload properties, as required:
- Host Name – the name of the machine where Unwired Server is running (read only).
- Maximum Heap Size – the
maximum size of the JVM memory allocation pool. Use K to indicate kilobytes, M
to indicate megabytes, or G to indicate gigabytes. For production
recommendations on this value, see Unwired Server
Replication Tuning Reference in System Administration.
- Minimum Heap Size – the
minimum size of the JVM memory allocation pool, in megabytes. For production
recommendations on this value, see Unwired Server
Replication Tuning Reference in System Administration.
- Thread Stack Size –
the JVM -Xss option.
- User Options (in Show
optional properties) – other JVM options. For example, you can enable JVM
garbage collection logging by setting -XX:+PrintGCDetails. Or you can set the permanent space which
allocated outside of the Java heap with DJC_JVM_MAXPERM; the maximum perm size must be followed by K, M,
or G, for example, -XX:MaxPermSize=512M. Note
that DJC_JVM_MAXPERM is not visible to Sybase Control
Center.
Finally, you can define the Solution Manager URL into which trace files can be
uploaded for troubleshooting assistance: -Dcom.sap.solutionmanager.url=<SolutionManager_URL>.
- Click Save.
