Support for Sybase Database

fyi, start with sybase support following http://docs.codehaus.org/display/ACT/How+to+add+support+for+new+databases guidlines. I'm in contact with Bernd Rücker to provide CI asap.

Who had the idea of a unique constraint on a nullable column? For each database there is a given workaround expect Sybase.

searching for workaround for h2 expression

alter table ACT_RU_EXECUTION
add constraint ACT_UNIQ_RU_BUS_KEY
unique(PROC_DEF_ID_, BUSINESS_KEY_);

alter table ACT_HI_PROCINST
add constraint ACT_UNIQ_HI_BUS_KEY
unique(PROC_DEF_ID_, BUSINESS_KEY_);

Found a solution for Sybase 15:

create unique index ACT_UNIQ_RU_BUS_KEY on ACT_RU_EXECUTION
(case when BUSINESS_KEY_ is null then ('pk-' + ID_) else ('bk-' + BUSINESS_KEY_) end, PROC_DEF_ID_);

But next problem raises on ant task 'create.db.schema' cause of the sql autocommit default which is false. Sybase can not create a functional index on a multi-statement transaction. The autocommit could be set over the specific db properties file which can lead to an undefined db state if one transaction cause an error.

The CycleDbSqlSessionFactory#dbSchemaCreate() must also be able to switch the autocommit mode.

Another option is to use mutiple sql files each executes in one transaction.

Feedback?

By the way: The same problem one of our customers experienced on Informix. The nullable but unique business key seems to get a problem on some databases...

The Autocommit-Mode sounds reasonable smiley

To support these scripts is it necessary to add autocommit="true" at sql on target name="create.db.schema"

Hi all,

I have ported activiti 5.5 to Sybase Adaptive Server Anywhere (>= Rel 9). But i'm not familar with Maven and though a have not followed the tips explained in the wiki. If subject of interest, I can post these scripts here.

But my problem was, that the Sybase JDBC driver jConnect does not Support JDBC-conform BLOB/CLOB access.
Though I have changed all mybatis mappings like that:

jdbcType=BLOB, typeHandler=org.apache.ibatis.type.ByteArrayTypeHandler

Another problem is, that the used alias name membership refers to a reserved word. Though I have changed this to membershp to solve the problem.

In the global mappings.xml I have added the type handlers

               <typeHandlers>
                  <typeHandler javaType="_byte[]" jdbcType="LONGVARBINARY" handler="org.apache.ibatis.type.ByteArrayTypeHandler"/>
                  <typeHandler javaType="string"  jdbcType="LONGVARCHAR"   handler="org.apache.ibatis.type.StringTypeHandler"/>
               </typeHandlers>

With best regards, Torsten

Patches for version 5.5 attached to http://jira.codehaus.org/browse/ACT-726

@Torsten
- How you solve the constraint problem with nullable columns?
- How you find the problem with the reserved key word membership? All maven tests run successfully on sybase.

I used the sybase sql type image instead of blob/clob. So no changes to the mapping are necessary.

No problem on ASA using
create index ACT_UNIQ_RU_BUS_KEY on ACT_RU_EXECUTION (PROC_DEF_ID_, BUSINESS_KEY_);
create index ACT_UNIQ_HI_BUS_KEY on ACT_HI_PROCINST (PROC_DEF_ID_, BUSINESS_KEY_);

After startup, some action (I think the deployment of BARs) failed with an error message pointing to a problem with reserved words.

I used also Image-Type in the database column in ASA. But the mybatis configuration uses Blob/Clob, the jConnect driver does not support. Dou You have used jConnect or jTDS? On ASA jTDS does not work, only jConnect.

You have to a use unique index. So you did not solve the constraint problem with nullable columns.

Membership is only on ASA a reserved keyword not on ASE.

I used jTDS. On ASE jTDS works.

Do you need to use ASA?

You are right, this is not accurate. But I have assumed, Activiti works fine on other DBs, though the Java code is working and no unique constraint violation will occur.

Yes, we have OEMed that DB in our products.
