Re: [h2] H2 db getting corrupt on mac
It was my mistake in describing. we do use the BACKUP command and then
since it produces a zip file, we create a new zip file and copy inputStream
to another outputStream to create a new zip file (with some configs related
to the DB) and then give that zip file to the customers to use as their
backup.
Maybe the issue happens while writing the zip file to another file or maybe
it's during backup. We've yet to encounter why.

Re: [h2] H2 db getting corrupt on mac
Testing the backup sounds like a good idea. thanks. Still not sure what would cause a corrupt db because if it happens while its in use, then this is not a solution but it's a start. -- You received this message because you are subscribed to the Google Groups "H2 Database" group.

[h2] H2 db getting corrupt on mac
I don't know what's causing it. We have a feature that backs up the H2 DB file and zips it via java. the DB is in use when we back it up (all it does is copy the h2 file) When we tried to use it, it's corrupted. This is the stack trace when I try to open it ZipOutputStream append = new ZipOutputStream(new FileOutputStream(fileFullPath)); java version "1.7.0_55" on mac and file size is 1.4 MBs and we have a lot of / (slashes) stored. I am not sure where to begin to find it. Is it H2 ? is it our code writing/copying the file? (tests can't reproduce it) What is this error ? >java -cp lib/h2*.jar org.h2.tools.Shell -url "jdbc:h2:./data/path;CIPHER=AES;TRACE_LEVEL_SYSTEM_OUT=0;ALLOW_LITERALS=NUMBERS" -user sa -password "pass1 pass1" Exception in thread "main" org.h2.jdbc.JdbcSQLException: General error: "java.lang.ArrayIndexOutOfBoundsException: 4" [5-173] at org.h2.message.DbException.getJdbcSQLException(DbException.java:331) at org.h2.message.DbException.get(DbException.java:160) at org.h2.message.DbException.convert(DbException.java:283) at org.h2.table.RegularTable.removeRow(RegularTable.java:397) at org.h2.store.PageStore.redo(PageStore.java:1537) at org.h2.store.PageStore.redoDelete(PageStore.java:1511) at org.h2.store.PageLog.recover(PageLog.java:334) at org.h2.store.PageStore.recover(PageStore.java:1371) at org.h2.store.PageStore.openExisting(PageStore.java:361) at org.h2.store.PageStore.open(PageStore.java:285) at org.h2.engine.Database.getPageStore(Database.java:2210) at org.h2.engine.Database.open(Database.java:603) at org.h2.engine.Database.openDatabase(Database.java:226) at org.h2.engine.Database.(Database.java:221) at org.h2.engine.Engine.openSession(Engine.java:56) at org.h2.engine.Engine.openSession(Engine.java:160) at org.h2.engine.Engine.createSessionAndValidate(Engine.java:139) at org.h2.engine.Engine.createSession(Engine.java:122) at org.h2.engine.Engine.createSession(Engine.java:28) at org.h2.engine.SessionRemote.connectEmbeddedOrServer(SessionRemote.java:313) at org.h2.jdbc.JdbcConnection.(JdbcConnection.java:105) at org.h2.jdbc.JdbcConnection.(JdbcConnection.java:90) at org.h2.Driver.connect(Driver.java:73) at java.sql.DriverManager.getConnection(DriverManager.java:571) at java.sql.DriverManager.getConnection(DriverManager.java:215) at org.h2.tools.Shell.runTool(Shell.java:147) at org.h2.tools.Shell.main(Shell.java:80) Caused by: java.lang.ArrayIndexOutOfBoundsException: 4 at org.h2.index.PageBtree.getRow(PageBtree.java:172) at org.h2.index.PageBtreeLeaf.remove(PageBtreeLeaf.java:228) at org.h2.index.PageBtreeIndex.remove(PageBtreeIndex.java:238) at org.h2.table.RegularTable.removeRow(RegularTable.java:379) ... 23 more -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
