JTDS → Microsoft JDBC Driver for SQL Server

Importing a PKCS12 keystore into a JKS keystore

Wow, I did not know keytool can actually do this.

keytool -importkeystore -destkeystore keystore.jks -srckeystore keystore.p12 -alias tomcat

Grails: adjust Hibernate settings to prevent "org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement"

Grails 3.3.2 project. GORM, Hibernate, JTDS (with Microsoft SQL Server). I kept getting the following exception:

Adding the default_catalog: (name of the database here) and default_schema: (name of the schema, usually dbo) underneath the hibernate: section in application.yml solved the issue.

Stop+Disable and Make Automatic+Start Windows Services using PowerShell.

When you need to make sure all Cisco services (Windows services) are stopped and set to manual but you need to do this on 20 servers and there's at least 10 services per server then you start doing things like this:

Stop and set Startup type to Manual:

Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Stop-Service $_.Name}
Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Set-Service $_.Name -StartupType Manual}

Set Startup type to Automatic and start:

Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Set-Service $_.Name -StartupType Automatic}
Get-Service |Where-Object {($_.DisplayName -like 'Cisco*')} |foreach {Start-Service $_.Name}
