DB2 Create Database takes long time

Asked 2021-May-18 at 12:50

I'm new to Db2 and just installed v11.5 on my Ubuntu 18.04.

I referred these two links for setup purpose:

IBM and DCON

I'm using DB2 CLI to create a database. On typing in create database and press enter, it just stays there; there's no output.

I checked the db2diag.log as well, it stops at this:

2021-05-18-15.41.46.618309+330 E653248E505 LEVEL: Event PID : 29136 TID : 140104312022784 PROC : db2sysc 0 INSTANCE: db2inst1 NODE : 000 DB : SOURCE

Tried 3-4 times; on one occasion I just let it be and it took around 30-40 mins but it created the database. I'm not sure if I'm missing out any initialization step.

Kindly guide.

The time it takes to create your skeleton Db2-LUW database is mainly determined by your I/O and logging configuration, and whether or not you get swapping/paging. The CPU speed is less important than the I/O throughput for the create database action.

As an example: my Db2-LUW v11.5 on ubuntu 18.04 and 20.04, the create database completes with the following times as reported by the time tool (with zero paging) and no containerization/virtualization:

with nvme(ssd): around 2 minutes
with spinning disk ext4 4k sector size, 256mb cache sata3, 3.5inch 7200rpm: around 4 minutes
with spinning disk ext4 512byte sector size, 64mb disk cache sata3 2.5 inch 5400rpm : around 10 minutes.

If you have more than one physical drive and/or controller, it can help to put the transaction logs on a different drive / controller to the tablespaces.

So you can see that the performance varies greatly with the I/O configuration. You get what you pay for, and how you configure it.

For creation of other objects on the skelton database like tablespaces, tables, views, indexes, mqt's, routines etc, the performance will vary further, again dependent on your I/O and logging configuration.

Unable to Export complete MariaDB in DDEV project

ddev export-db creates gzipped output by default, so that's why you're seeing binary output. ddev help export-db will show you examples of what to do, for example:

If you can change the type of the Skus field, the common approach would be to declare a slice type that implements the sql.Scanner and driver.Valuer interfaces and use that instead of the unnamed []*CustomizedComponent type.

...

ANSWER

Answered 2020-May-09 at 18:00

Several reasons:

make_unique takes custom deleter, so it is supposed to handle custom allocation. Passing allocator to a hypothetical allocate_unique is cumbersome.
The same as .release() can provide a junction with a code that manages lifetime differently (including API in C interface that use raw pointers).
Historical reasons, make_unique was only introduced in C++14.

Note also that starting C++17 the main reason to prefer make_unique over new was removed, so you may see make_unique only as a syntax sugar, not as exception safety utility. See Why use std::make_unique in C++17?

Tatsu: How to validate/process arithmetic like expressions in semantic actions

...

ANSWER

Answered 2020-Feb-14 at 00:36

To check for pre-defined identifiers during parse you need a Symbol Table.

You add symbols to the table in the semantics for the grammar clauses in which they are defined, and consult the symbol table in the semantics for the grammar clauses in which they are used.

Because TatSu preserves full information for the source input, it may be easier to check for those semantics after the parse, using a walker. The errors reported can be precise to the line an column number, and users usually don't mind that syntactic errors are reported first, and semantic errors later, because TatSu parsers normally stop on the first error (there's support for parse recovery in Tatsu, but it's undocumented).

Symbol tables during the parse phase are necessary only in languages in which a token may, or may not be a keyword depending on context (yes, PEG can handle some context-sensitive cases with the help semantic actions).

Update or Insert SQL with Powershell NULL values

Asked 2019-Sep-23 at 14:59

Trying to figure out how to add a MSSQL-Null value if the value isn't present.

This works so far, it will insert new rows and if match it will update the columns. But if for example termniationdate isn't specified, instead of assigning a null value in the database it will write 1900-01-01 and text fields will be blank instead of null.

Tried to add +[DBNull]::Value but made no change. Kind of run out of ideas. :)
