Updating SAP JVMLocate this document in the navigation structure

Use

The SAP JVM is included in all products based on the SAP NetWeaver Application Server Java 7.3. It resides in the sapjvm_6 subfolder which is located under /usr/sap/(SID)/SYS/exe/jvm/ <platform> / <patchstring> .

The installation of the SAP JVM is included in the installation of the product. The following procedure describes what you have to do to upgrade to the newest SAP JVM version without upgrading your whole product.

Procedure

An upgrade to the newest available version is possible by importing SAP JVM patches using the Java Support Package Manager (JSPM). The JSPM applies these patches as “SAP JVM Support Packages” to the software component “SAP JVM” . After deployment to the file system of the SAP NetWeaver Application Server, there is an automatic replication to each server instance using the sapcpe program.

In short, applying an SAP JVM patch takes the following steps:

  1. Download the SAP JVM patch from the SAP Support Portal. E.g., for SAP NetWeaver 7.3, navigate along the following path: Start of the navigation path https://service.sap.com/patches Next navigation step Support Packages and Patches - Browse our Download Catalog Next navigation step SAP NetWeaver and complementary products Next navigation step SAP NETWEAVER Next navigation step SAP NETWEAVER 7.3 Next navigation step Entry by Component Next navigation step Application Server Java Next navigation step SAP JVM 6.1 End of the navigation path

    Choose your platform, e.g. Windows Server on IA64 64bit .

    The file name looks like SAPJVM6_XX-YYYYYYYYY.SAR, choosing the highest available patch level is recommended.

  2. Log on as <sid>adm.

  3. Copy the patch in the inbox of the JSPM The default inbox directory is defined by profile parameter DIR_EPS_ROOT.

  4. Start JSPM and logon as Administrator. Start the process with the following command:

    • Windows: <drv:>\usr\sap\<SID>\<INSTANCE><NR>\j2ee\JSPM\go.bat

    • Unix: /usr/sap/<SID>/<INSTANCE><NR>/j2ee/JSPM/go

  5. In the Select Package Type screen, choose Single Support Packages and Patches (advanced use) and choose Next .

  6. In the Specify Queue screen, you should be able to see the target patch level for the SAP JVM and it should be higher than the patch level of the current version. Deselect all patches you don't want to install and choose Next .

  7. In the Check Queue screen, you see the patches you have selected. If you agree, choose Next .

    Caution

    The Application Server Java will be stopped. In case of an ABAP/Java double stack system, the ABAP system will be stopped, too.

  8. After the queue has been deployed, you get the Completed screen where the status of the SAP JVM should show DEPLOYED .

  9. Choose Exit to finish the patch procedure.
