(110) Check AS400 configuration

Normally, QMirror/DR should run well under common AS400 configuration. If you have a slow replication speed, you will need to check or tune your AS400 configuration.

Please refer to the following paragraphs to check with your AS400 configuration. Watch the QMirror/DR performance status and tune accordingly.

1. Use command STRTCPSVR to start FTP server and DDM server.

2. Manage access using FTP exit programs.

You can provide additional security by adding FTP exit programs to further restrict FTP access to your AS400. Please refer to
https://www.ibm.com/support/ knowledgecenter/ ssw_ibm_i_73/rzaiq/ rzaiqreferenceexit.htm

3. Use command DSPUSRPRF QUSER to verify that the user’s status is *ENABLED.

4. Use command STRHOSTSVR *ALL to start the optimized host server daemons.

5. Amend QZDASOINIT/QUSER PJ jobs back to normal priority.

   a) QZDASOINIT runs priority based on QSYS/QPWFSERVER *CLS

   b) Default value = 20

   c) Use command CHGCLS CLS(QPWFSERVER) RUNPTY(20)

   d) Restart QSERVER subsystem

6. Use command CHGPJE SBSD(QSYSWRK) PGM(QSQSRVR) MAXJOBS(*NOMAX) to set SQL maximum number of jobs to *NOMAX. You might refer to http://publib.boulder.ibm.com/ infocenter/wasinfo/v6r1/ index.jsp?topic=/ com.ibm.websphere.base. iseries.doc/info/iseries/ ae/tins_is_cfgsql.html

7. Tune AS400 server for Java SQL Database access. Please refer to http://archive.midrange.com/ java400-l/200210/ msg00036.html

8. QMirror/DR needs these ports for the connection to AS400 – 23, 446, 449, 8470, 8471, 8472, 8473, 8474, 8475, 8476.
