Dear Christian,
Thanks for your response. I use "pin" so that a context can store many databases. If I don't use "pin", a newest database will override the current database (see context.dbs.list.elementData). Please tell me how can I use many database on one context.

Quoting Christian Grün <[email protected]>:

Hi,

it?s probably a better idea to avoid explicit (un)pinning of nodes;
all commands should correctly do this for you. Out of interest: why
did you choose to do pinning by yourself?

Best,
Christian

Dear BaseX team,
I want to ask you how to use the class AlterDB to change a database name. It
always throws the exception DB_PINNED_X although I use "unpin" before using
AlterDB. I found the problem is that the method TableDiskAccess.locked(db,
this) always returns "true". Please see the attachment and help me solve the
problem.
Thanks in advance.
