When Java 11 for z/OS was announced, zEDC compression was not supported.

Is that still the case? Will zEDC be supported in the future in Java 11? Or e.g. only on z15+?

The ability to leverage zEDC was a great selling point of Java, but since the Java 11 announcement the future has been very unclear.

I have some usage of compression in Java. I don't know whether to tell customers to stay on Java 8 until zEDC is available in Java 11, or assume that it is gone and disable compression to save CPU.

Does IBM have a e.g. statement of direction for Java and zEDC?

Hello Andrew, circling back to this thread. Last week we shared a roadmap of this at ISV Disclosures meeting (4/26 - "Java on zSystems Update"). Please have a look to see if you have access to the recording.  Thanks.

Thanks James, I will see whether I can get access to the recording.

However, this isn't an ISV interface. This is an interface usable by application Java programs, so any changes potentially affect all customers with zEDC and Java on z/OS. Restricting the information to ISVs doesn't seem to make sense - ISVs are probably the least affected by any changes in this area.

(Obviously I don't know the details form the ISV disclosure yet, so this comment is based on current public information and this thread so far. If zEDC functionality is returning, all is good.)

Following up on this regarding Java 17.

Is the zEDC capability already built-in Java 17?

Any known drawbacks on Java 17 or should have the same z/OS related capabilities as Java 8?

Java 17 is now publicly available, so there doesn't seem to be a reason for secrecy about the current zEDC status.

I have looked for zEDC information in the Java 17 documentation and found none. So I assume the status is unchanged from Java 11:

The zEDC (zEnterprise® Data Compression) Express® adapter and the Integrated Accelerator for zEDC solution for z15™, which were mentioned in the zEnterprise Data Compression documentation for version 8, are not currently supported. As a result, the CPU consumption and performance of Java applications that make extensive use of data compression might be affected. Support is intended to be added in a later release.

Is that a correct reflection of the current status, regardless of any future plans?

Subject: Java zEDC future?

Java 17 is now publicly available, so there doesn't seem to be a reason for secrecy about the current zEDC status.

I have looked for zEDC information in the Java 17 documentation and found none. So I assume the status is unchanged from Java 11:

The zEDC (zEnterprise® Data Compression) Express® adapter and the Integrated Accelerator for zEDC solution for z15™, which were mentioned in the zEnterprise Data Compression documentation for version 8, are not currently supported. As a result, the CPU consumption and performance of Java applications that make extensive use of data compression might be affected. Support is intended to be added in a later release.

Is that a correct reflection of the current status, regardless of any future plans?

Following up on this regarding Java 17.

Is the zEDC capability already built-in Java 17?

Any known drawbacks on Java 17 or should have the same z/OS related capabilities as Java 8?

Thanks James, I will see whether I can get access to the recording.

However, this isn't an ISV interface. This is an interface usable by application Java programs, so any changes potentially affect all customers with zEDC and Java on z/OS. Restricting the information to ISVs doesn't seem to make sense - ISVs are probably the least affected by any changes in this area.

(Obviously I don't know the details form the ISV disclosure yet, so this comment is based on current public information and this thread so far. If zEDC functionality is returning, all is good.)

When Java 11 for z/OS was announced, zEDC compression was not supported.

Is that still the case? Will zEDC be supported in the future in Java 11? Or e.g. only on z15+?

The ability to leverage zEDC was a great selling point of Java, but since the Java 11 announcement the future has been very unclear.

I have some usage of compression in Java. I don't know whether to tell customers to stay on Java 8 until zEDC is available in Java 11, or assume that it is gone and disable compression to save CPU.

Does IBM have a e.g. statement of direction for Java and zEDC?

Hello Scott, there is a few other things in the pipeline that we want to update in the what's new page you referred to, so stay tuned.

We don't normally create an official IBM announcement for service stream releases such as 11.0.20.1 (the one that contains zEDC support), so I published a blog on it instead.

Or are you referring to an official announcement on Semeru (Java) v17 on z/OS GA? If so, the announcement link is here - https://www.ibm.com/docs/en/announcements/semeru-runtime-certified-edition-zos-17

James,

This is great news for the platform.  Can you point to an announcement beyond the blog?  I look at this page and it's still only at version 11.0.19.0.

Thanks,
Scott

The ability to leverage zEDC was a great selling point of Java, but since the Java 11 announcement the future has been very unclear.

I have some usage of compression in Java. I don't know whether to tell customers to stay on Java 8 until zEDC is available in Java 11, or assume that it is gone and disable compression to save CPU.

Does IBM have a e.g. statement of direction for Java and zEDC?

Hi Group,

According to the documentation The latest release requires z/OS 2.5 (5650-ZOS), or later.

This makes it very hard to adopt Java 17 as customers are still using z/OS 2.4.
It feels very weird that Java 17 is not enabled to run on supported z/OS versions.

Any plans to enable support for z/OS 2.4 as well? 

Thanks in advance,
Offer Baruch

Thanks for the update James!

This is really great.

Hi Andrew / Roded, zEDC is now available in v17. See latest blog post - 

https://community.ibm.com/community/user/ibmz-and-linuxone/blogs/james-tang1/2023/12/07/semeru-for-zos-v11021-and-v1709-ga

Hello Andrew, Semeru 17 on z/OS doc has been updated to reflect zEDC status - https://www.ibm.com/docs/en/semeru-runtime-ce-z/17?topic=migrating-from-earlier-releases-semeru-certified-edition-zos

Please connect again in Dec and I shall have another update by then.

This is good news, thanks, except for the Java 17 status.

"We don't normally create an official IBM announcement for service stream releases"

I understand that policy as a general procedure, but when the Java 11 announcement says that zEDC is not currently supported, it would be helpful to have a similar prominence for the support being added. Otherwise it is difficult for customers to research the zEDC support.

The status of Java 17 is now unclear. Previously, it was reasonable to assume that the status was the same as Java 11. But now maybe Java 17 needs the same information that was in the original Java 11 announcement... that zEDC is supported in Java 11 but not currently supported in Java 17?

Hello Scott, there is a few other things in the pipeline that we want to update in the what's new page you referred to, so stay tuned.

We don't normally create an official IBM announcement for service stream releases such as 11.0.20.1 (the one that contains zEDC support), so I published a blog on it instead.

Or are you referring to an official announcement on Semeru (Java) v17 on z/OS GA? If so, the announcement link is here - https://www.ibm.com/docs/en/announcements/semeru-runtime-certified-edition-zos-17

James,

This is great news for the platform.  Can you point to an announcement beyond the blog?  I look at this page and it's still only at version 11.0.19.0.

Thanks,
Scott

Andrew / Offer,

Java 17 is now publicly available, so there doesn't seem to be a reason for secrecy about the current zEDC status.

I have looked for zEDC information in the Java 17 documentation and found none. So I assume the status is unchanged from Java 11:

The zEDC (zEnterprise® Data Compression) Express® adapter and the Integrated Accelerator for zEDC solution for z15™, which were mentioned in the zEnterprise Data Compression documentation for version 8, are not currently supported. As a result, the CPU consumption and performance of Java applications that make extensive use of data compression might be affected. Support is intended to be added in a later release.

Is that a correct reflection of the current status, regardless of any future plans?

Thanks James, I will see whether I can get access to the recording.

However, this isn't an ISV interface. This is an interface usable by application Java programs, so any changes potentially affect all customers with zEDC and Java on z/OS. Restricting the information to ISVs doesn't seem to make sense - ISVs are probably the least affected by any changes in this area.

(Obviously I don't know the details form the ISV disclosure yet, so this comment is based on current public information and this thread so far. If zEDC functionality is returning, all is good.)
