The post Netezza CREATEXID DELETEXID appeared first on iExpertify.

set show_deleted_records = true

select createxid,deletexid, * from table

If you want to see just the deleted rows , just select where deletexid is not zero

select createxid,deletexid, * from table where deletexid !=0

Once you can see your deleted data, and figure out which transaction you are trying to undo, you can simply re-insert the data

insert into table
select * from table where deletexid=142233; –transaction id from delete.

To undo an update, just re-insert the deleted rows and delete the inserted rows.

insert into table 
select * from table where deletexid=146443 ;–transaction id from update
delete from table where createxid=146443; –transaction id from update

To undo an insert, use the below SQL

delete from table where createxid=1434443; –transaction id from insert

The post Host, SPA in Netezza appeared first on iExpertify.

Key terms and terminologies used in the context of Netezza appliance.

Host: A Linux server which is used by the client to interact with the appliance either natively or through remote clients through OBDC, JDBC, OLE-DB etc. Hosts also store the catalog of all the databases stored in the appliance along with the meta-data of all the objects in the databases. It also passes and verifies the queries from the clients, generates executable snippets, communicates the snippets to the S- Blades, coordinates and consolidates the snippet execution results and communicates back to the client.

Snippet Processing Array: SPA is an array of S-Blades with 8 processor cores and 16 GB of memory running Linux operating system. Each S-Blade is paired with Database Accelerator Card which has 8 FPGA cores and connected to disk storage.

Snippet Processor: The CPU and FPGA pair in a Snippet Processing Array called a snippet processor which can run a snippet which is the smallest code component generated by the host for query execution.

Appliances that end of support

IBM has announced the end-of-support (EOS or End-of-life) dates for three generations of Netezza / IBM PureData analytics appliances

Netezza Skimmer, Twinfin, Striper models have already passed their EOS date before the mid of 2020. Mako models will reach end of support by October 2023.

Appliances that end of support

IBM has announced the end-of-support (EOS or End-of-life) dates for three generations of Netezza / IBM PureData analytics appliances. Additionally, Netezza Skimmer, Twinfin, Striper models have already passed their EOS date before the mid of 2020. Mako models will reach end of support by October 2023.

IBM is not extending support

IBM is NOT offering an extended support service beyond their announced end-of-support date. When Netezza devices are reaching end of life, some companies are choosing to temporarily support it with their existing team without help from IBM until the final strategic solution is in place. Also, there are 3rd parties who are supporting service for these devices. examples are

1. https://www.natrinsic.com/netezza/?hsLang=en
2. Data Warehouse Support Services with Smart Associates (smart-associates.biz)

Most are finding a replacement

Most companies I know are finding a replacement solution and migrating their data warehouses. Snowflake or Redshift are the two most common choices I have heard. What are your companies migrating toward?

Staying with IBM Netezza

What happened to Netezza? – Journey to AI Blog (ibm.com)

Read the blog entry from IBM. They are not strategically moving away from Netezza technology itself. But the popular Netezza appliance that enabled a lot of companies achieve their Data warehousing strategy is changing. They are suggesting these 2 major alternatives:

• IBM® Netezza® Performance Server for the cloud – support current workloads but is adapted for cloud performance
• For on premises, in the IBM Cloud Pak® for Data System hyperconverged architecture, Netezza Performance Server clients connect to the Netezza Performance Server host, which runs as a Docker container named ipshost1 on the system Control Plane node.

Move to the cloud

In conclusion, most solutions are moving toward cloud workloads and if your industry is still hesitant to move towards cloud due to regulatory, privacy or lesser control, you could find on premises alternatives. Most client I have heard of are moving to AWS (Redshift) or Snowflake on (AWS or Azure) as IBM stops support and trying to get you into their IBM cloud solution.

The post Netezza Temporary Table Space appeared first on iExpertify.

In IBM PureData System for Analytics, each disk is roughly equally divided into 3 partitions:
1. The first partition holds the primary copy of one dataslice
2. The second partition holds a mirror copy of a dataslice from a different disk.
3. The temp partition is used to store data that is generated during query execution. Temporary tables, intermediary results, etc.

• When we use temporary tables, it is this third partition, the temp space, that we risk filling up.
• It is important to only create the minimum number of temporary tables needed at a time. It is also important to only make the temporary tables as large as needed.
• Temporary tables are local to a session rather than a specific query. This means that the table may be used repeatedly within a user session. That is the major difference between Temporary tables (multiple use) and derived tables (single use). A Temporary table is materialized in swap space. However, it is not discarded until the session ends or when the user manually drops it.

When explicitly creating large temporary tables used in JOINs it is recommended to GENERATE STATISTICS on the temporary table.
