Issue/Introduction

Based on the OS upgrade to z/OS 2.3, JAVA V8.0 may be installed in the z/OS 2.3 system. Are there any impacts on the SYSVIEW Performance Management Option for DB2 R19.0/R20.0

Are there any impacts on the SYSVIEW Performance Management Option for DB2 R19.0/R20.0 in the following cases?

In the case that the JAVA isn't installed in the z/OS 2.3 environment. (In this case, any versions of JAVA will not be installed in the z/OS 2.3 environment.)

In the case that the JAVA V8.0 is installed in the z/OS 2.3 environment.

 

Environment

Release : 20.0

Component : CA Insight Database Performance Monitor for DB for z/OS

Resolution

Java runtime is needed for the install of the CA DB2 Products.

See member DBMSEDIT in R200.SAMPJCL library.

/* SMPJHOMEPATH - The name of the directory in the UNIX file system*/

/* that contains the JAVA runtime. */

...

/* Set the JAVA path */

Gather Configuration Values

Additionally I do not think customer can work without Java installed in the z/OS environment, for example for CA SYSVIEW for DB2 in the

future if they like to work with the REST API interface they need to communicate with USS and probably working with Java.

See the details in the following link:
