Netezza Performance Server 11.2.1.4 interim fix release notes

Deployment options: Netezza Performance Server for Cloud Pak for Data

Version 11.2.1.4-IF1 is an interim fix that is applicable only to Netezza Performance Server for Cloud Pak for Data.

Before you upgrade to 11.2.1.4-IF1, you must back up tables with a compression ratio greater than 7.95 and databases that contain these tables. After the upgrade is complete, truncate the tables from their databases and restore them. To identify tables with compression ratio greater than 7.95, see https://supportcontent.ibm.com/support/pages/node/6564067.

Tables that were identified as having a compression ratio greater than 7.95 before upgrade must not be accessed until they are restored after upgrade.

Make sure you completed the backup of the listed databases before you upgrade Netezza Performance Server.

Known issues

Fixed-format data files that contain numeric fields might be loaded incorrectly into the database. For more information, see https://www.ibm.com/support/pages/node/6583457.
nzrestore fails if backup is taken with BUCKET_URL having slashes.
Whenever the nzrestore failure happens with following error:
```
[Restore Server] : Starting the restore process
[Restore Server] : Operation aborted 
Error: Connector exited with error: 'The specified key does not exist. with address : xx.xxx.xx.xxx'.
```
Check the backup command and verify whether BUCKET_URL is having slashes as shown in the following example:
```
BUCKET_URL=bakcupbucket/subdir/
UNIQUE_ID=2024-01-12
```
WORKAROUND:
Modify BUCKET_URL and UNIQUE_ID as shown:
```
BUCKET_URL=bakcupbucket 
UNIQUE_ID=subdir/2024-01-12
```
Note: UNIQUE_ID is a combination of string that is taken from BUCKET_URL after the first slash and actual UNIQUE_ID. Pass these two arguments to the nzrestore command.
